This is embarrassing...

I feel like a fool for not quite understanding the question, BUT some random thoughts to get the noggin going:

To get a whole number, you can use

(int) rand(360) or trunc(rand(360)).

To get it to stop rotating, could you not just use "==" instead of ">="? Could there be any chance that it is calculating a collision on every frame because the instance is right on the ground plane?

On a seperate idea, instead of a collision event, have you considered using a mag(velocity) with an if statement to determine if the instance is at rest? Its not useable in all cases of course, but I prefer to avoid collision events if possible. Here is an example of what I mean:

If I have your question wrong, please let me know.

Ahh...good call mate!....==

I have since got this to work using a noise(particleShape1.particleId)*10 in place of the rand(360)...but now that you mention the == Im pretty sure thats what was messing up the calculation....Ill go in and recheck that to confirm.

props for the quick reply....

And thanks

dan, dan, dan... have I taught you nothing?

your runtime is giving random rotational values on Y each frame after the first collision. If you want the rotation to stay static after the collision you probably want to reverse your if statement like this

if (particleShape1.event < 1)

rotation = <<random rotation>>;

then when the particle collides it will just hold the last rotation value because it doesn't get updated any more
