Particle Troubles - Invalid Datablock

by David Bigerstaff · in Torque Game Builder · 01/08/2006 (10:04 pm) · 3 replies

I'm having a nightmare tonight, i've just posted an empty thread (sorry about that), after having typed up what i wanted to say, so here we go again :P

Well the main reason for my post is that i'm having trouble creating a particle. I've done the basic tutorial fine and i cant for the life of me figure out why this wont work.

The specific error i'm getting is t2dParticleEmitter::setImageMap() - t2dImageMapDatablock Datablock is invalid! (particles5ImageMap)

function createFirework()
{
         %magic = new t2dParticleEffect() { scenegraph = t2dScene; };
         %magic.loadEffect("~/client/effects/smallThruster.eff");
         %magic.setPosition( $player.getPosition() );
         %magic.playEffect();
         echo("$player.getPosition() = " @ $player.getPosition() );
}

I call that function every time i click the mouse and the console.log looks like this each time.


t2dParticleEmitter::setImageMap() - t2dImageMapDatablock Datablock is invalid! (particles5ImageMap)
$player.getPosition() = -20.000000 22.923536


Thanks for looking!

Are you defining the particles5 graphic along with your other graphic datablocks? Assuming you're using the particles5 image from the tutorial, you want to add this to your datablocks:
datablock t2dImageMapDatablock(particles5ImageMap)
{
	imageName = "~/client/images/particles5";
	imageMode = cell;
	cellWidth = 64;
	cellHeight = 64;	
	filterPad = false;
};

Philip is correct; the "smallThruster.eff" is complaining that a datablock it uses "particle5Imagemap" isn't defined.

This is one of the datablocks defined in the "demoDatablocks.cs" file that are used for the demos and demo-particle effects. You can obviously go into the editor and change which image-map/animation the effect uses but it's best to save it as another name if you do. Either that or just add the image-map definition back in as per Philips instructions.

Cheers,

Thanks guys i got it working.

It turned out that i'd initially taken out the exec("./demoDatablocks.cs");

and then I didnt have particles5.png in my image directory.

Thanks again!
