How do you make random local velocity for particles?
I'm pretty new to Unity and found I couldn't make the particle effect I was going for (using a particle emitter component) without random local velocity. My first thought was to make a script adding values which would translate to world values then be added to the existing rndVelocity options. I can't figure out how to do it though. This is what I tried:
var rndLocalVelX : float = 0; var rndLocalVelY : float = 0; var rndLocalVelZ : float = 0; var particlez : ParticleEmitter; var relativeDirection : Vector3;
function Start () { var randomAdd : Vector3; randomAdd = Vector3( rndLocalVelX, rndLocalVelY, rndLocalVelZ);
relativeDirection = transform.TransformDirection(randomAdd);
particlez = GetComponent(ParticleEmitter);
//adding a random value to local velocity:
particlez.rndVelocity += relativeDirection;
}
I don't understand what you're trying to do, but anyway, the variable called Rnd Velocity is already local random velocity. So you can just set that value directly.
do you need to add positive and negative velocity? If so, use Random.Range(min, max)
randomAdd = Vector3(Random.Range(-rndLocalVelX, rndLocalVelX), Random.Range(-rndLocalVelY, rndLocalVelY), Random.Range(-rndLocalVelZ, rndLocalVelZ));
you would set this as Velocity instead of rndVelocity ofcourse
