Particle rotation

[ParaToxic]

Hey I would ask you if I can set the rotation of the sprites or particles emitted by a emitter?

I see that the rotation of the sprites are random and you can't create something like sparks flying away from the position of the emitter like a firework.

 

Is there a way to set the rotation ?

 

Thanks

You can set rotation speed with SetEmitterRotationSpeed(). But it sets "speed" only, while "direction" of rotation for each particle will be chosen randomly.

 

...and you can't create something like sparks flying away from the position of the emitter like a firework.

 

Why is that? Recall my old video:

Ok thanks I think I going to make my own emitter system for something like sparks of explosions

Why?

I can't see why you can't use usual LE2-emitter for creating sparks effect.

For helicopter dusting effects we had to rotate the emitter rapidly to get a radius, there's only so many kinds of effects you can get the LE system to do. It's functional but primitive.

 

BTW Daimour I was inspired by your video to add extra debris effects to our explosions. For which I thank you.

Because when I use a spark texture ,which have the size of 64x256 pixels it turns allways in an other direction.I don't know how to fix that..

It's pleasant to hear.

I see. You trying to use a spark picture with trail.

Try to use a star-like (or roundish shape) spark without trail. And use the motion for creating trail effect (like in video).

Animated texture solving it Big sprite with baked sparks frames.
