I tried to make it so:
So trace sprite spawns behind a bullet so often, so it looks like trail. It is common way to make trail effect.
Bullet stepping is needed here because bullet moves too fast so spawning a trace just every tick is too infrequently to achieve a trail effect. Because trace sprites will spawn on a lot of distance from each other.
And overall it works, but not for bouncing.
Here is the problem with bouncing:
When bullet bouncing from some object, it stops to spawn a trace sprites for a bit of time... I can not understand how to fix it.
Thank you for your help in advance!
