I make mistakes and call them video games.

 ```function box(_x,_y,_w,_h) return{ x=_x, y=_y, w=_w, h=_h } end function get_cols(a) local gx,gy=flr(a.x/8),flr(a.y/8) local ex,ey=flr((a.x+a.w-1)/8),flr((a.y+a.h-1)/8) local list={} for i=gx-1,ex+1 do for ii=gy-1,ey+1 do if fget(mget(i,ii),0) then add(list,box(i*8,ii*8,8,8)) end end end return list end function collide(a,_dx,_dy,list,side) local ca={ x=flr(a.x), y=flr(a.y), w=a.w, h=a.h } for i=1,#list do local v=list[i] if col(v,ca) then if _dx>0 then a.x=v.x-a.w side["right"]=true elseif _dx<0 then a.x=v.x+v.w side["left"]=true end if _dy>0 then a.y=v.y-a.h side["down"]=true elseif _dy<0 then a.y=v.y+v.h side["up"]=true end end end end --diss code expects that "a" have a --dx and dy function move(a) local sides={ ["left"]=false, ["right"]=false, ["up"]=false, ["down"]=false } local l=get_cols(a) a.x+=a.dx collide(a,a.dx,0,l,sides) a.y+=a.dy collide(a,0,a.dy,l,sides) if sides["up"] or sides["down"] then a.dy=0 end if sides["left"] or sides["right"] then a.dx=0 end return sides end function col(a,b) return not( (a.x>b.x+b.w-1)or (b.x>a.x+a.w-1)or (a.y>b.y+b.h-1)or (b.y>a.y+a.h-1) ) end```

this is the code that i use for collisions with the map
is not perfect but it works

hehe

the code is based in the pygame way of doing collisions
probably not the best way of doing collisions in pico-8

but it works for me atleast

the way to use this, is to just call the move function
in a table that have dx and dy

dx="direction in the x-axis"
dy="direction in the y-axis"

and update dx and dy

i not a pico-8 expert so, i probably using a lot of tokens

i saw that pico8 got a free version so i decide to make a small game

i kinda new in to developing games ,and that why the game is so simple , or maybe is because pico8 token count said he hates me,
who knows.

about the game he is kinda_like a rougue like , he very inspired in the binding of issac, but simpler
every door do something

is the item room

# pink one

is a mystery can have enemies or good_stuff

# the brown one

is just a enemy room

the controls are the keybord keys and z and x
z are shot
x use card

diss game is not that good , is very short and you can see that, is more like train to flex my programing skils that anything .
btw the code is pretty bad , have fun :)
