https://scratch.mit.edu/projects/546863032/ I want explosion to fade away rather then use clear all, preferably preventing range show from making explosions invisible, right now costume 1 towers are explosive for testing purposes

progressively make the colour different, just do the same script with a different colour. you won't need to do erase all because it will layer on top, erase all after the exploion anim is finished.

I just easily did it, just make the brightness of the pen colour progressively brighter, do it four times and do intervals of 0.1 seconds.
if you have any questions just go into this project and the code is there: https://scratch.mit.edu/projects/557247426/
Hope this helps!
