Bad math?

Hello. I have a custom F11 map, but i has some problem with "waypoint" create.

When i'm click on map, the waypoint makes not in the cursor position, the waypoint has a small offset (left, right, up, down) and this is not good.

 

local screenX, screenY = guiGetScreenSize()

local mapTextureSize = 3072
local bigmapMapUnit = mapTextureSize / 6000

local bigmapWidth = screenX - 60
local bigmapHeight = screenY - 60
local bigmapX = 30
local bigmapY = 30
local bigmapCurrentZoom = 1.5

local playerX, playerY, playerZ = 0, 0, 0 -- automatic updating in render

function getWorldFromMapPosition(mapX, mapY) -- This function dont work correctly (mapX, mapY = cursor relative X,Y)
	local worldX = playerX + ((mapX * (((bigmapX + bigmapWidth) / bigmapCurrentZoom) * 2)) - ((bigmapX + bigmapWidth) / bigmapCurrentZoom))
	local worldY = playerY - ((mapY * (((bigmapY + bigmapHeight) / bigmapCurrentZoom) * 2)) - ((bigmapY + bigmapHeight) / bigmapCurrentZoom))
	
	return worldX, worldY
end

function getMapFromWorldPosition(worldX, worldY)
	local mapX = (bigmapX + bigmapWidth / 2) + ((worldX - playerX) * bigmapCurrentZoom) * bigmapMapUnit
	local mapY = (bigmapY + bigmapHeight / 2) - ((worldY - playerY) * bigmapCurrentZoom) * bigmapMapUnit
	
	return mapX, mapY
end

 

Thanks the replies.

Is it an issue with 2D display of waypoint on the custom map or the actual 3D position of the blip/marker/whatever?

Solved.
