I want to make contrails for a plane but I don't want the contrails to be seen while on the ground or when I'm not moving. If someone could tell me how to make a button turn on/off a particle emitter that would be great....
This isn't a request site, but here's some pseudocode:
Connect to the button's click event If particleEmitter.Enabled is true, set it to false Otherwise, set it to true
