I am currently creating a new ParticleEffect to simulate rotor wash from a helicoptor on water. To do this I need to set the rotation on each particle when created to point in the direction of its velocity. The idea is that each 'wake' particle is emitted and sent out from a circle.
I can create a Operator to change the rotation based on the angle between two vectors but an Operator occurs every frame. This is very inefficent, considering the dot product and other calculations needed! I just want to set each particle to have a different orientation upon creation. The ParticleSystem can set the orientation of ALL particles to be the same but I need something similar to Operator that only occurs on particle creation. Does anyone have any clues on how to resolve this?
