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
