I need to make an object in a collision with another object appeared once the particles, and when they were new clashes did not appear. I decided that this can be achieved in this way. What do you suggest? ("trigger once" certainly does not help)
Make sure your particles "Type" property is set to "One-Shot".
You did not understand me, I need to particles worked only once in a collision with an object, but not every time.
explain with an example. I need to do to effect checkpoint. When a character goes through it should work "fireworks". But it should not be triggered every time a character goes through it.
