Script-born particles

by Samuel Marcus · in Torque Game Builder · 11/14/2006 (1:30 am) · 5 replies

I'm trying to create an effect without using the editor, but my test-case crashes Torque. It looks like an infinite loop and I suspect it has to do with graph-fields being undefined. When you create a new particle effect/emitter, are its graph-fields given defaults or need all of them be defined by hand (even things like spin or what-have-you which I may not even be using)?

Alternatively: does someone have a "naked" particle effect scripted somewhere that I could see as a sort of template?

thanks!

They all have defaults.

So are there any obvious reasons why adding one might cause the game to crash Torque on loading?

Here's what I have:

datablock t2dImageMapDataBlock(rain)
{
	imageName = "~/data/images/rain.png";
	imageMode = key;
	size = "32 216";
	frames = 4;
};

function rainGod::makeItRain(%this, %scenegraph)
{
	%rainStorm = new t2dParticleEffect()
	{
		layer = 3;
		sceneGraph = %sceneGraph;
	};
	%droplet = new t2dParticleEmitter();
	%droplet.setImageMap(rain, 0);
	%droplet.setEmitterType(LINEX);
	%droplet.setAttachPositionToEmitter(false);
	%droplet.setFixedAngleOffset(0);
	
	%rainStorm.addEmitter(%droplet);
	%rainStorm.setEffectLifeMode(KILL, 5);
//	%rainStorm.playEffect();
}

When I uncomment the last line, it crashes. (the game creates this class and then calls MakeItRain)

Resolved! addEmitter() doesn't do what I thought it did.

Well, 5 years later, but here's how to fix it:

change:
// %droplet = new t2dParticleEmitter();
%droplet = %rainStorm.addEmitter();

remove
%rainStorm.addEmitter(%droplet);
