Using ParticleEmitterNode as an explosion.
by Derrick Austin · in Technical Issues · 02/02/2009 (5:47 pm) · 3 replies
I'm trying to use a ParticleEmitterNode as an explosion since Explosion does not show up on the client side. Unfortunately, I can not get the EmitterNode to disappear so I end up with a bunch of blue blobs floating around my maps... :(
Here is the code I am using... Any ideas?

I seem to remember that from a while back. Maybe it got fixed ... maybe not.
If you do have problems create a delete function and have the create function schedule that.
I might be wrong, I might be thinking of datablock functions deleting themselves.

Doesn't having something (ie: a function) schedule it's own delete cause problems? I seem to remember that from a while back. Maybe it got fixed ... maybe not.
If you do have problems create a delete function and have the create function schedule that.
//psuedo-code
function create_explosion(%this, %that, %theother)
{
//your stuff here
MissionCleanup.add(%p);
%this.scehdule(1000, "delete_explosion");
}
//------------------------------------
function delete_explosion(%p)
{
%p.schedule(2000,"delete");
}

I haven't experienced any issues - but if I do - I will certainly try the code ups ^
