Particle Help

hey guys searched the forum as im sure this has been answered but couldnt find it.

I have a rocket with a particle effect. On the emitter offset I have -38 so it comes out of the bottom perfectly. TH eproblem is when the rocket turns upside down or to the side, the particles are still on the bottom of the actor, not relative to the actors orientation, which is what I need. Thanks.

First thing that comes to mind is to check the Velocity/Position tab of the Particles behavior and make sure Relative to: is set to Actor and not Scene

youll need to use sin and cos to keep the paricles right no matter of rotation and direction

try this

in the emiiter for the x position have

-13*cos(self.Rotation)

and in the emiiter for the y position have

-13*sin(self.Rotation)

cheers

Thanks John, that did it.

Well.....almost. It worked fine for a little rotation but a lot of it and its still not centered. Hmmm.

JohnPapiomitis

then you just adjust the numbers.

change -13 to something lower like -30 ect.

If that makes it worse change it up like -10, -5, 0, , or 10 ect

Just to clarify I have

x amount*cos(self.rotation) in the X value

and

x amount*sin(self.rotation) in the Y value

Is that correct? And from there just adjust the numbers?
