Strange things happening to particle system in game

When I instantiate a game object with the particle systems attached this happens for about a minuet

anyone have any ideas how I can stop this from happening?

What exactly is wrong?

In the image, the texture for the fire is spread out randomly through the scene, really hard to explain.

All over the scene? I use particle instantiation all the time and have never seen this happen. How large is the ellipsoid of your particles?

If you just have your (original) particle system in your scene, it doesnt do this?

I honestly havent come across this, so I dont know what could be causing this. It may not be convenient, but could you post a video of the issue?

x - 0.5
y - 1
z - 0.5

and yes its fine if the original is in the scene, only when its instantiated does this happen.

will make a vid quick

Was just thinking, might be a problem in your code. Would you be willing to post your code for the effect being instantiated? would prob help narrow down the problem; have you checked the code to see if that was the problem?

the instantiating code? thats the only code that touches the particle system. nothing else, this couldnt be causing the problem could it? >.<

heres the video: http://dl.dropbox.com/u/27684978/issue.avi

Saw the video, looks like the particle system was set to do that. What are you particle system settings? do you have some of the random force parameters turned on/working? it looks like you have the particles set to fly off, which is pretty normal in a particle system when you want that effect.

I dont know what your code looks like, so cant say much else. Look here for the API portion related to controlling particle emission via scripting: http://unity3d.com/support/documentation/ScriptReference/ParticleEmitter.html
Maybe you accidentally scripted the particles to emit the way in the video?

random force isnt set and im really not using any code on the particle system. I instantiate a prefab which contains the particle system with the effect i want. Is it possible that the movement of the fire is causing this? like a delay? the fires catching up to the position it stopped at?

I don’t know, but I still think it’s your code. The script you’re using to instantiate the prefab- what’s it look like?

I just have a feeling it’s an easy fix, but who knows.

sorry for not replying, had some computer issues so had to format my hard drive, once i re installed unity the particle system no longer behaved like that, so no idea what was wrong with it but thanks :slight_smile: working now
