Custom events [Solved]

sausage

Having a little problem with custom events. I inserted one into the animation list, but a second one causes the project to break.

For example:

[BlockAnim]
DefaultKeyDuration  = 0.15; 
KeyData1            = tile1
EventName1	    = AR1
EventTime1	    = 0.1
EventValue1	    = 1.0
KeyData2            = tile2
KeyData3            = tile3
KeyData4            = tile4

This works perfectly and I'm hooked on the concept. Every first frame, a custom event is generated with

...
  switch(_pstEvent->eID)
  {

	case orxANIM_EVENT_CUSTOM_EVENT:
...

If I insert a second one in my config like this:

[BlockAnim]
DefaultKeyDuration  = 0.15; 
KeyData1            = tile1
EventName1	    = AR1
EventTime1	    = 0.1
EventValue1	    = 1.0
KeyData2            = tile2
EventName2	    = AR2
EventTime2	    = 0.1
EventValue2	    = 1.0
KeyData3            = tile3
KeyData4            = tile4

..the project breaks.

The final output from the debug log was:

[2010-11-05 15:13:02] <ASSERT> (orxAnim_AddEvent() - c: mporxcodesrcanimorxanim.c:869) [Assertion failed] : <(orxAnim_GetEventCounter(_pstAnim) == 0) || (_fTimeStamp > _pstAnim->astEventList[orxAnim_GetEventCounter(_pstAnim) - 1].fTimeStamp)>

Thanks for the output, it helped me find the issue right away.

So basically the answer is that there can only be one custom event on a given timestamp. Internally timestamps are used as keys so they can't be duplicated on the same channel (here the event channel). If you still want to have both events fired at the same time, you can go wild with the decimals:

EventTime1 = 0.09999
EventTime2 = 0.1
EventTime3 = 0.10001

These 3 events will be fire at the same time but don't share the same key. Sorry about the inconvenience, I'll have to figure out to handle things differently internally to allow more than one event per timestamp.

Ahhhhhhh!!! That's totally it. Thank you!

A tutorial based on this discussion can be located in the wiki here: http://orx-project.org/wiki/en/orx/tutorials/community/sausage/realistic_walk_movement

Excellent tutorial, thanks for it!

I should probably reorganize the tutorial home page so that the community tutorials should be the first thing people see there.

I may be bias, but for some reason I think this is a great idea

iarwain

I'll do it right now, but I was afraid you'd feel forced to, you know, write other tutorials! :P

Grey

Yeah, you might be right... such a cruel slave-driver you are haha

sausage

Haha. Yep. You'll notice I moved the english tutorials under the main page in the wiki. The other tutorials in other languages should probably be moved to suit.

Ahah, apparently not that efficient as a slave driver, though! :P

Yep, very good idea. Not sure I'll venture myself to do the same for Chinese as I can't read it, unfortunately. Same for Spanish actually and the French pages are still non-existent. I blame me.
