One issue I have is that the resources are stored in .GFF files, which I'm able to extract the majority of. Now I would prefer to extract this data during runtime. So, I see some options:

1) Add a custom loader (like in orxAndroid_RegisterAPKResource()), and load from there. My concern is that some things may not translate correctly. For example the image data is stored as two different entries in the gff. A palette entry and then then a data entry. Naturally I have a routine that translates that combination into 24-bit RGB or 32-bit RGBA.
2) Load the data in C and not in .ini. In other words use orxObject_Create(), etc... to create the objects.
3) Explode all the data into .bmp/png files on disk and then load.

I prefer 1) as I have the backend for that and it would allow people to overlay any extensions/mods in the .ini/config files--which would be slick.

I'm not opposed to 2), but that seems to defeat the purpose of ORX since that would be ignoring the whole data-driven .ini/config.

I don't like 3) at all because that is just seems super lame to me. Also, I'd have copyrighted data exploded on disk as opposed to its original format. Additionally there are certain parts of the original engine that use alternating palettes to create effects, which I haven't thought of how I would implement that yet.

Naturally I'd love to hear opinions.

Specifically any direction on 1) to get me started? I can keep reading the code, but any direction/examples would be helpful. Preemptive apology if I missed where this was documented already.

New to the Orx Engine. I've compiled it using Visual Studio, I notice that by default Orx uses FASTCALL when exporting to DLL. Is there a way to change to that CDECL? Without having to change every FASTCALL name to CDECL?

I am trying to use the example iOS project, but the example doesn't seem to work. It builds just fine but crashes with a stack overflow error when run in the simulator. Near the top of the console log I see this error message

When I update to the latest build it crashes with the same console log message and this stack trace

Any suggestions on how to get this config to work?

As a side thought I was also hoping to make a server/client architecture in the future, and was wondering whether its a terrible idea tying things to animations in this case, and how much having the server not actually display the animations on the screen will affect its animation routine.

[22:12:20] [ANIM] [orxAnimSet.c:orxAnimSet_CreateSimpleAnimFromConfig(2283)] AnimSet [JamesAnimationSet]: Failed to create anim [RunAnim], couldn't create any frames.

My sprite sheet is 1840x256, the sprite size is 80x128, the first row is idle and second row is running animation.
It seems to work fine with the idle animation, and my "RunAnim" seems to semi-work if I set the RunAnim: TextureOrigin = (0,65), however anything above this it crashes even though its 256 pixels tall.

Is there something simple I'm missing here, I dont have any scaling or anything applied to the object. Any help is appreciated.

With [Physics] / ShowDebug at true, i don't see neither the physic debug shape, nor coordinates axis.

That's odd, because with simpler objects (ufos which have no animations, body defined in the object entry) , i can see the physic shapes.

[Ufo]
Graphic = UfoGraphic
Body = UfoBody
Pivot = center

[UfoBody]

Solid       = true
SelfFlags = ufo
CheckMask = ufo # hero

And it gives that:

I'm not sure where i should define Physics.
I tried to define Body in [Player] but with a box type, it raises an assert (no assert with sphere, strangely). Anyway, i see only coordinates axis in this case, not the debug shape.

Thank you for reading

So is there a prescribed procedure for taking a game I worked on in visual studio on windows and getting it built on my mac? I quickly tried cloning down the repository to the mac but realized there is no mac build folder in the project. I don't want to do any authoring on the mac, just want to be able to build a finished game that was authored on windows. Any advice for how to best proceed?

thanks!

Thanks very much for any guidance. Here is a shot of the hint I'm seeing with the typo in it:

i'm looking for the most elegant way to manage game scenes ?

My first thought was to create a GameScene class and then create "MainMenuScene", "PlayScene" and "OptionsScene" classes and simply call current_scene.run() in my Run function.

But this solution felt ... hacky, so what's the official way to achieve this ?

Thanks

I'm facing a problem with this tutorial and it's torturing my mind.

I'm trying to make a title menu with two item "Play" & "Quit" highlighted when you hover with your cursor, exactly what's proposed with this tutorial.

I was wondering if there is any cool orx-config style way of doing camera lag in general. It can sometimes be a nice effect for certain kinds of games....I can imagine having a maximum velocity.x/y options for child objects that allow them to catch up to their parents rather that adopt their positions instantly. A max lag distance could also be set so that the child can't get more than a certain distance away from its parent position. I didn't see anything like this so far, so curious if there is already some way to do this that I'm not seeing (other than code it myself, which is fine).

thanks

https://ncase.me/sight-and-light/

For visualization, I'm using the orxDisplay_DrawPolygon function to see my light blocking polygons and also to fill in the resulting "light area" polygon. Since I can't use that function to fill a non-convex polygon, I'm just filling in a series of triangles that can be made from the rays and their endpoints. All working as expected.

My plan was to use the resulting polygon (or collection of triangles) to multiply onto a light map texture that contains my lights in order to create some simple shadows. What I can't figure out yet is how to draw the polygons somewhere other than the main display (ie, onto my light map texture). As far as I can tell, the DrawPolygon feature is tied to the current display, correct?

I'm probably missing the obvious, but what would be the suggested way to get the light polygon drawn onto a texture?

The wiki points to main .cpp which I used.

Within /ImGuiOrx/imgui/examples I find several main .cpp versions for a variety of APIs.

Regarding the high framerate at the beginning, some OpenGL drivers go into busy loops with VSync if VSync is requested too soon after the creation of a window. To prevent this, we request VSync only half a second after the window's creation.

I realize I am using the "GLFW + OpenGL2, using legacy fixed pipeline" which may account for those behaviors.

Which APIs does Orx support and which does igtest.cpp use?

I haven't done anything yet other than look over how the lighting tutorial works, but I have a general question about how to handle lights in a large map. So, the character light is easy because in my setup, the character is always at the center of the screen. I'd like to be able to place lanterns in the map to light up various areas. Of course, these light sources may or may not be on the visible part of the map. I think one way to do this is to look at any light sources in the world (these would probably be regular orx objects) and determine if their location is visible on the screen, and if so, update an array of available lights with the appropriate light color, position, radius, etc. This assumes a setup with a static array of lights similar to the tutorial approach. That would limit the number of lights in a scene to whatever size the array is, and would maybe require some prioritization if there are too many light sources in the scene.

Having never tried to do something like that, I'm wondering if that is a sound approach, or is there some more standard way of handling this that makes more sense. Any advice or suggestion is welcome.

Here is the parameter list, and I've set a default value for the new parameter HighlightAlpha

If in the shader if I use

color.a = 0.35;
it works fine,
but
color.a = HighlightAlpha;

makes the shader not work at all.

I also see when I try to set the parameter in code, that it doesn't like the float value

Not sure what I've done wrong here.

I don't think it is feasible to generate a bunch of orxOBJECTs for each block in the grid for performance reasons. I was thinking of keeping my world in a large 2d array of bytes, with the values representing what type of block is at that location. (1 = dirt, 2 = grass, 3 = rock , etc). For rendering, I'd loop through the visible portion of the array (dependent on player position) and render rectangles according to the values in the array. I've actually done something like that a few years back with my own home-grown stuff. Any hint as to how I could render out textures in Orx directly like that?

The other thing to handle would be collision. I feel like that also may require some custom collision handling rather than using the orx body. Since I'd know where the player is on the grid, I really only have to check a few of the values in the array that are near the player for collision. I know collision can be tricky, but think I can handle doing that part.

So, I'm curious if that sounds like a way to go, or if there are other well-known approaches? Probably the biggest unknown for me is how to render the textures directly without using orxOBJECTS (unless there is a workable approach using them)

thanks for any comment!

Any suggestion for how I can get those .h files to show as part of the project?

thanks

I'm specifically talking about the Windows setting System > Display > Scale and layout > Change the size of text, apps, and other items.

When this is set to anything other than 100%, it causes only screen size (orxDisplay_GetScreenSize) to be scaled. The mouse position is not scaled with the screen size. This cascades and causes mouse to world coordinates and object placement to be calculated incorrectly.

I've posted an example below. With Scale set to 100%, left clicking the mouse makes the orx logo follow the mouse. If the scale is set higher, the orx logo is no longer placed under the mouse correctly. When the mouse is in the top left corner, the logo is underneath the mouse pointer. As you move the mouse down and to the right, the logo moves at scale across the screen the same direction. (i.e. When the mouse will move 100 pixels to the right, the logo moves much more than 100 pixels to the right.)

How can I prevent this from happening, other than forcing a user to change the setting to 100% which may make other parts of the screen hard to read?

This is not the whole code it is just things that are regarding to the problem.
I can post the whole code if you like.

My first issue is that I can't seem to scale my character without affecting the camera. If I set my character's scale to 0.5, it still appears the same size on the screen and the camera appears zoomed in. Likewise if I set its scale to 2, the camera is zoomed out so the character appears still the same size. I'd like to be able to adjust the character's size relative to the other things in the world, but can't seem to do it with the parent arrangement. I tried IgnoreFromParent = Scale on the camera, but it had no affect.

The second issue relates to rotation. I've set the camera to IgnoreFromParent = rotation and this works as expected so that when my character gets rotated for some reason, the camera remains upright, which is what I want. This works as long as the camera's position is set to 0 on the x and y axis relative to the character. But, I'd like to offset the camera by -100 in the y direction so that my character is not in the dead center of the screen, but plays closer to the bottom of the screen. (I should use some fraction of the actual screen height instead of -100). But, the issue is that with the offset, if my character rotates, it now has an effect on the camera such that the camera seems to move right or left horizontally. It doesn't rotate the camera, but the horizontal motion is not desirable. It sort of makes sense that the offset causes this, but I'm hoping there may be a way to eliminate it. I so far haven't found an option that helps with this one so for now my character is center screen. If there is no option with the parent scenario, perhaps I just have to use a timer and set the camera location myself?

thanks again for any help you can offer!

thanks for any help!

But now I'm trying to get the speed of a moving platform, which is moved using FX as setup in the ini file. It looks like GetSpeed is always returning a zero vector on this object. Is it possible to get the current speed of such an object that is moved by a speed effect? Probably I've done something wrong but can't find it yet.

Here is the effect on the object in question:

    [HorzElevatorFX]
    SlotList    =HorzElevatorSpeedSlot
    KeepInCache = true
    Loop        = true

    [HorzElevatorSpeedSlot]
    Type        = Speed
    Curve       = sine
    StartTime   = 0
    EndTime     = 11
    Absolute    = true
    StartValue  = (100,0,0)
    EndValue    = (-100, 0, 0)

Any idea why I might be misssing this file? When I built on Windows with Visual Studio two weeks ago, there was no problem whatsoever. I want to use orx this weekend at a GameJam, so any help would be much appreciated

Same thing happens if I cause an exception to happen and visual studio tries to come to the top to show me.

Regular windowed mode (fullscreen = false) doesn't have a problem allowing VS to get control.

Is there any way around this? I know I can just debug in windowed mode, which is what I do, but would be nice to be able to in fullscreen. I came across this link that seems to indicate it has to do with the window position flag being set. Is this relevant?

https://developercommunity.visualstudio.com/content/problem/44507/setting-a-breakpoint-in-a-fullscreen-app-project-c.html

thanks

Let me know what I've missed and how to proceed. Looking forward to trying this out.

The various ways I've tried to specify this in the Position= line of an object don't seem to work. Assuming this can be done in the ini file, how would you set an object position's x value at the screenwidth - 100 (for example)

thanks again for all the help!

When I create a new project the game is always in fullscreen. When I edit the main ini file i've FullScreen to false, even when I use orxDisplay_SetFullScreen(false); I still have my game in fullscreen.

Did i miss something ?

If I add ScreenWidth & ScreenHeight in my Display section for something like 1280/720 I'm still in fullscreen but borderless. (see screenshot)

Thanks

My basic questions is - what is the recommended way to iterate through all orxOJBECTS and remove them (for exiting a level of game play, for example). More context below:

I've setup a simple system to allow navigation between various "levels" - for example, a main menu with ability to quit or proceed to Level 1. My Level 1 is a simple Space Invaders style game. While this level is in play, I want the user to be able to hit Esc to return to the main menu. This works fine, but I'm having trouble getting rid of all of the objects used in level1 before switching to the main menu. So a couple of questions:

To remove objects, I'm using orxObject_SetLifeTime(MyObject, 0);

It works well for removing objects I have references to, but I'm curious if that is the orx-like way to do it, or if there another recommendation.

To remove children of a parent object (my enemy fleet is composed of a single object with a bunch of children enemy objects), I've found how to iterate through the children and set their lifetimes to 0, so that works well to remove my enemies when the user returns from level 1 to the menu.

The problem is with my player's missiles...they are setup with a simple spawner that activates when the spacebar is pressed (pretty much the same as in the Beginner's guide). If I launch a bunch of missiles then return to the menu, I'm not sure how to find those objects and remove them since I don't have references to them.

Sorry for the long-winded message. I assume there must be a master list of objects that can be iterated for this purpose, but I haven't found it in the short amount of time I've spent looking around.

Thanks!

I downloaded and installed Orx today, and when I generated a new project with the "init.bat" file, I went to the Windows Code::Blocks project and opened it. Everything looked good, but when I tried to build and run the new project, CB pulled up "orxString.h" and highlights two errors: stricmp and strnicmp aren't declared in the scope, apparently. Through a series of trials and errors I found that the problem seems to stem from "strings.h." I also found that these commands are important to the error log and assertions.

I don't understand what could be happening, and I've Googled all over the place, and also searched the forums, but have found nothing.

Any help would be much appreciated!

Thanks,
Wolf

Any tips for good ways for doing pass trough platforms in Orx?

One possible solution is using a separate physics body with a small Y size for the character "feet" and using a small Y size physics body for the platform itself. Then, make the object feet teleport to the top using SetPosition if the object Speed.fY is negative and touch the Platform. But it seems a little complicated.

One can make an object "non-solid" for some objects, and solid for others? (And change it in real-time by code?) or similar, in Orx?

So if a condition is met, it can bypass the platform.

A Godot video tutorial with a preview of the effect can be found here: Pass Through Platforms in Godot Engine

The topmost platform in this picture moves left and right. For some reason, however, when I move my little Megaman onto the platform, he does not move with it, instead remaining static. I thought I may be able to solve it by continuing to call the physics handling event for as long as the player remains on the platform, and using it to apply some impulse that'll move the player alongside the platform, but there does not seem to be a way to accomplish this - at least, I haven't been able to find anything while looking through the tutorials, the examples and the API doc. It only covers one-and-done type collision deals which doesn't help me at all.

While looking through the wider web, I did find a possible solution. That's with the use of the Friction value. If I give both the player and the platform friction, then that will make the platform carry the player properly. But that comes with its own problems: even with friction as low as 1, it makes the player move slower while on the platform that they'd otherwise be (right now, moving left and right on the bottom platforms and in the air gives a Speed value of 319, but moving left and right while on the platform lowers it to 223). And also, having any friction at all will make the player cling onto the side of the platform if they hit it from the side and move towards it in the air. I think this could maybe be solved by setting Friction to 1 while the player is stationary but setting it to 0 when in the air or holding left and right. Problem there is that there doesn't seem to be a way to change Friction during runtime either! There's no orxObject_SetFriction nor anything like it.

I feel like there's a really easy solution to all this and I'm just not seeing it for some reason.

In it, I'm asked to mess with the jelly blob's animation cycle via this type of code:
[JellyWobbleAnim0003]
TextureOrigin = (0, 0, 0)
[JellyWobbleAnim0004]
TextureOrigin = (64, 0, 0)
However, it doesn't seem to actually work? The animation of the jelly blob looks exactly the same as before. It even appears to have no effect whatsoever, as I tried slowing the animation down as well as adding a ton of extra frames that show the same sprite, but the executable still isn't picking up on any of those extra frames, it just keeps showing the same 3 from the spritesheet.

Is the information on the tutorial outdated or am I doing something wrong?

I've created a new project using the init script, but I'm not sure how to build it. I see the visual studio project files in the build/windows folder, but I'm not sure what to do with them. (I've never used Visual Studio before, and the version I have installed is the free version, if that makes a difference.)

I'd really like to use Sublime or QtCreator to build the project since I've used them in the past, but is this too much of a hassle? Should I download codeblocks or codelite instead, or can I build it with Visual Studio Code?

Thanks!

I followed this setup-guide and this building-setup for Orx (Windows 10). Both worked without any errors but when I open the project (created with init) VisualStudio say: ' [...]: "orx.h": No such file or directory '.
Because I worked before with SFML I added the "include" and "lib" directorys in the project setting but nothing changed. Recreating the project (init) doesnt helped. I didnt found my problem in the forum so I created this discussion! I hope somebody can/will help me!

Thanks!

ScreenPosition = (Center?, Center?)

If it can't be done through the config, then how would it be done through my source file, in c++?

Is there any way someone can provide an example of say, tinting the screen red? Maybe a Gaussian blur?

I'm currently on Windows setup, and I'm still in browsing mode, haven't setup the environment yet, I know how to setup minGW & Sublime Text 3 (ST3) to compile C programs.

What I want to know is, can I use it to compile Orx projects easily, Also I know there's a ST2 pack for Orx, can we use it with ST3.

Thanks.

I am new to the ORX world, happy to be here, I'm coming from javascript and haxe background. What attracted and gravitated me towards Orx is it's data-driven concept.

And I'm thinking about going the pure C way rather than C++. And last few weeks I've been wrestling with the C.

What worries me most than anything else is 'Memory Management'. Coming form garbage collecting scripting languages to mother of programming languages is bit intimidating.

I'm hoping Orx takes care of memory management, if not, would you learned Orx masters show me the way to how to do it.

Thanks a lot

I've attached a .zip of the project files if anyone wants to have a look. The structure is mostly identical to that of the tutorial's, with the main difference being the files generated by the init script.

I was curious if its okay to write code for use with orx in pure C. I know that orx was written in C. I was also curious if there was a way to launch a new project that creates a C source file instead of one that is in C++. I'm a beginner so I beg your pardon if these questions are of the "wrong" type.

For my newly created project, may I delete the cpp default source file and create another? Is it permissible to change the file extension of a .cpp file to .c in order for my IDE and compiler to recognize that I want to compile C?

Thank you in advance. I appreciate your patience.

I'm using Codeblocks and MinGW on Windows 7.
