I got this snake game made by a guy named "Richard Davey" (I give him all the credit) and now I want to tweak it.
Instead of having white squares for the snake I want to have a person I made in MS paint 16x16 and instead of a red square for the food I ant another person I made in MS paint 16x16. I already made the people. Can anyone help me?
HERE'S THE CODE:
STARTINGUP:

sync on

` our snake sprite
ink rgb(255,255,255),0
box 1,1,15,15
get image 1,0,0,16,16
` our fruit
ink rgb(255,0,0),0
box 1,1,15,15
get image 2,0,0,16,16
` our border
ink rgb(0,0,255),0
box 1,1,15,15
get image 3,0,0,16,16
` "where is the snake?" array
` because the snake is 16x16 in size the game grid is 40x30
dim grid(40,30)

I put a little thing at the end that lets you play agin by pressing the spacebar, but other than that every thing is the same.
