You’re welcome!
But I don’t see an advantage to using a sprite for one pixel. I’m thinking you have x & y variables, so if you’re drawing the screen every TIC() I think you’d clear the screen and redraw everything. So draw whatever the pixel might collide with first, then use pix to read the color of where the pixel will be, and if it’s the color of the colliding object then you have a collision. Otherwise, use pix again to write the pixel orange or whatever.
I haven’t programmed a line of Tic-80 code yet, though…I’m just getting this from reading Itch and the Tic-80 wiki.
