How can I make custom Fx

[War]

All in the title. I would want especially to make sprite-based fx.

I've  been doing sprite based effects for awhile now. Simply create your sprite, and then import it into the sprite manager. Then either spawn the sprite over the thing you want it to spawn onto and create a delay command to delete it, or, you can create an enemy and put the sprite onto that and then create a delay command to delete the enemy once the animation is over.

Platform Builder would need also a custom fx manager, with the choice of making it particle-based or sprite-based, then we would have to spawn it using commands

That'd be pretty difficult to make I think. I suggested a particle manager a long time ago.

I don't think it's too hard because I actually saw how other games allow users to manage and create particles. Such as Geometry Dash (in 2.2 it will be added) or in Minecraft.
GameMaker Studio actually has a system to create custom particles and that things. Might not be too complicated.

I know that, but putting it into PB might be hard I'm guessing.
