changing Physics::showDebug on-the-fly?

epoulsen

Was wondering if there was a way to programatically turn they physics debug outlines on and off (e.g. via a keystroke), or is it an ini-only type of thing?

I've tried the obvious places in the API:
orxPhysics
orxRender
orxDebug

Even grepped through the source. No luck.

To answer my own question:

void Game::togglePhysicsDebug() const {
	setPhysicsDebug(!getPhysicsDebug());
}

void Game::setPhysicsDebug(bool enable) const {
	orxConfig_PushSection(orxPHYSICS_KZ_CONFIG_SECTION);
	orxConfig_SetBool(orxPHYSICS_KZ_CONFIG_SHOW_DEBUG, enable ? orxTRUE : orxFALSE );
	orxConfig_PopSection();
}

bool Game::getPhysicsDebug() const {
	orxConfig_PushSection(orxPHYSICS_KZ_CONFIG_SECTION);
	bool ret = orxConfig_GetBool(orxPHYSICS_KZ_CONFIG_SHOW_DEBUG);
	orxConfig_PopSection();
	return ret;
}

That is indeed the way to do it programmatically.

Now if all you wanted to do was to do it on-the-fly in your game without having to modify the code, open the console and type:

set Physics ShowDebug true
set Physics ShowDebug false

You can also add a command alias to make it easier, either at runtime via the console:

Command.AddAlias psd set "Physics ShowDebug"

Or via your config file:

[Console]
psd = set Physics ShowDebug

And then use it in the console with:

psd true
psd false
psd 1
psd 0

EDIT: You can also list all aliases in the console with:

Command.ListAliases

Wow, okay. Didn't know there was a console. Couldn't figure out how to open it, son a whim I hit backtick (`), since that's where it is in so many other engines.

Is that key-binding hard-coded in?

That's the default key but you can change it in config:

[Console]
ToggleKey = KEY_*; NB: Defines the toggle key for activating the in-game console;

Any existing command can be executed in the console. I'm using it most of the time to check the current value of config properties, or to toggle FPS/Profiler/PhysicsDebug or even for creating new objects on the fly and testing a few things on them.
One can also use it to make a full dump of the config values into a separate file or even for saving config data in their originating file after tweaking them (but in that case comments and text formatting will be lost).
