I'm having issues with this code, everytime I run it i just get this

runtime error line 34 tab 3
if collide_map(player,"down",0) then
attempt to call global "collide_map" (a nil value)

here's my code:

 
--external functions--
function dns(sp)
	spr(sp.sp,sp.x,sp.y,sp.w/8,sp.h/8,sp.flp)
end

function player_update()
	--physics
	player.dy+=gravity
	player.dx*=friction

	--running
	if btn(⬅️) then
		player.dx-=player.acc
		player.running=true
		player.flp=true
	end
	if btn(➡️) then
		player.dx+=player.acc
		player.running=true
	end

	--jumping
	if btnp(🅾️) and player.landed then
		player.dy-=boost
		player.landed=false
	end

	--collision on y axis
	if player.dy>0 then
		player.falling=true
		player.landed=false
		player.jumping=false

		if collide_map(player,"down",0) then
			player.landed=true
			player.falling=false
			player.dy=0
			player.y-=(player.y+player.h)%8
		end
	elseif player.dy<0 then
		player.jumping=true

		if collide_map(player,"up",0) then
			player.dy=0
		end
	end

	--collision on x axis
	if player.dx<0 then
		if collide_map(player,"left",0) then
			player.dx=0
		end
	elseif player.dx>0 then
		if collide_map(player,"right",0) then
			player.dx=0
		end
	end

	player.x+=player.dx
	player.y+=player.dy
end
--function player_animate()
--end

here's just the section its calling out:

collide_map(player,"down",0) then
player.landed=true
player.falling=false
player.dy=0
player.y-=(player.y+player.h)%8

can anyone help me out with this

doing a cmd+f on your code block I don't see a
"function collide_map() ... end" or "collide_map = function() ... end"
If you do define this variable are you sure your doing it before this code is ran? if not debug it out a bit to see what's being ran if it's inlined?

apologies I missed my collision code

 
--collisions--
function map_collide(obj,aim,flag)
	--obj must be a table with (x,y,w,h)
	--will not work if aim is unassigned
	local x=obj.x	local y=obj.y
	local w=ob.w	local h=obj.h

	local x1	local y1
	local x2	local y2

	if aim=="left" then
		x1=x-1			y1=y
		x2=x					y2=y+h-1
	elseif aim=="right" then
		x1=x+w			y1=y
		x2=x+w+1	y2=y+h-1
	elseif aim=="up" then
		x1=x+1			y1=y-1
		x2=x+w-1	y2=y
	elseif aim=="down" then
		x1=x					y1=y+h
		x2=x+w			y2=y+h
	end

	--pixels to tiles
	x1/=8			y1/=8
	x2/=8			y2/=8

	if fget(mget(x1,y1),flag)	or fget(mget(x1,y2),flag)	or fget(mget(x2,y1),flag)	or fget(mget(x2,y2),flag) then
		return true
	else
		return false
	end
end


ya that's "map_collide" not "collide_map"
The error is saying "collide_map" is a nil value and it tried to call it using ()
1

oh shit... thank you, i just didn't see that
