I'm sorry, while I was typing the demo, very simple, in my mind grew up a dubt that need more test to do for getting an universal well working function of collision detection...
So,please gimme more Tempo to use for coding! I have no time in the week, I hope to have good time for weekend.
I tested Terry's Collision detection here with Spiders: https://qb64phoenix.com/forum/showthread...6#pid12986
Very similar to your images! (except mine wiggle and are freshly drawn every loop!) ;-)) Great minds...
I isolated spots needed to setup for Terry's collision code with '++++++++++ comment lines
in that code.
Steve's Collision Routine is next on my ToDo list, one routine looks handy for editing images or other things.
