A quick thing I made that creates customizable particles. It includes a (huge) block that lets you create particles from the current costume with many options. I made a few examples of what you can do with this. Tap the buttons! Setting fade to -1 makes the particle shrink until it despawns. Setting rotation to -1 makes the particle face towards its movement direction. To make it rotate left, set rotation to 360 minus the amount of degrees you want.
Credit me if you use this in a project. If you're making the particle sprite receive broadcasts to make particles, you should make a particle?=0 check to prevent particles from creating particles. Be aware of the 300 clone limit since this uses clones for the particles. Things that might be added in the future: Random rotation speed (you can use multiple create particle blocks for now) Random fade out time (you can use multiple create blocks for now)
