I've seen many of your raycasting programs and they are very impressive. I just have plans to make an fps or open world sandbox game, but I dont know where to start.
(enter the code below word for word)
spset 0,0
@move
b=button()
if b==1 then y=y-1
if b==2 then y=y+1
if b==4 then x=x-1
if b==8 then x=x+2
spofs 0,x,y
vsync 1
goto @move
