I try to use cell.c to detect a wall but it doesn’t work. Is there a better way of accomplishing this?

It should work. Keep in mind that cell co-ordinates are different than pixel co-ordinates. A cell is 8x8 pixels. For example a sprite is at 100,50, then you have to check cell 12,6. (100/8),(50/8)

Yes, that is the “sticky wicket”...
SPRITE is place by pixel precision, and CELL is placed by its grid number based on each cell being 8x8 pixels in size...
ALSO of great importance is that the sprite’s x,y coordinate is locate at its upper left corner... so technically you are only checking it’s upper left corner... you need to consider all 4 corners... it’s lower right location for a 1x1cell sprite is its X+8, and it’s Y+8... 2x2 cell sprites have its lower right corner as its X+16 and it’s Y+16...
