how can I use transparent background in example firework #88

Closed ape-casear closed 3 years ago

Is there exists any implement like Comet tail? background must be transparent

The fireworks demo uses the principle of multiple erasing. If you want a transparent background, need to set the Image Body. Can also simulate fireworks.
