im tryin to make a platformer base to use for future projects, but when travelling in positive directions, the collision is seemingly not detected until a full pixel further than it should be

 ``` local xd=n.x+n.speed.x+n.w/2*sgn(n.speed.x) local yd=n.y+n.speed.y+n.h/2*sgn(n.speed.y) n.grounded=false n.walled=false if fget(mget(xd\8,(n.y+n.h/2)\8))==1 or fget(mget(xd\8,(n.y-n.h/2)\8))==1 then n.x=xd\8*8+(n.speed.x>0 and -1-n.w/2 or 8+n.w/2) n.walled=true n.speed.x=0 end if fget(mget((n.x+n.w\2)\8,yd\8))==1 or fget(mget((n.x-n.w\2)\8,yd\8))==1 then n.y=yd\8*8+(n.speed.y>0 and -1-n.h/2 or 8+n.h/2) n.grounded=true n.speed.y=0 end n.x+=n.speed.x n.y+=n.speed.y```

this happens at any speed/width/height combination, and the readings are from the last 5 frames before a collision is registered
i have a feeling this is because of flooring but i dont know how i would fix it :3
