My project is not displaying correctly when I use toggleWorldWrapX and toggleWorldWrapY. It seems fine when I turn it off though. I’ve tried everything I know, can you guys take a look?
Attached are screenshots of what it looks like when toggleWorldWrapX and toggleWorldWrapY are set to true. Parts of the map flicker on and off as the player moves around (the black is not supposed to be there…)
My code:
[lua]
display.setStatusBar( display.HiddenStatusBar )
local storyboard = require( “storyboard” )
local scene = storyboard.newScene()
local mte = require(“MTE.mte”).createMTE()
local json = require “json”
system.activate( “multitouch” )
local moveTime = 300
local holding = false;
local angle = nil
– FUNCTIONS
local isSolid = function(level, levelPosX, levelPosY)
local tileX = mte.levelToLocX(levelPosX)
local tileY = mte.levelToLocX(levelPosY)
local tiles = mte.getTileProperties({level = level, locX = tileX, locY = tileY})
for i = 1, #tiles, 1 do
if tiles[i].properties then
if tiles[i].properties.solid then
return true
end
end
end
end
– Rounds a number to given decimal places
function round(num, idp)
local mult = 10^(idp or 0)
return math.floor( num * mult + 0.5 ) / mult
end
– Handler for Dpad touches.
local function dPadTouchHandler( event )
if event.phase == “began” then
display.getCurrentStage():setFocus(event.target, event.id)
event.target.isFocus = true
end
if event.phase == “began” or event.phase == “moved” then
holding = true
local dirX = event.x - event.target.x – Calculates the distance between the touch point and the centre of the Dpad
local dirY = event.y - event.target.y – "
angle = math.deg(math.atan(dirY/dirX))
if dirX < 0 then
angle = 90 + (90 - (angle * -1))
end
angle = angle + 90
if angle == 360 then
angle = 0
end
--angle = round(angle, 0) – Round to integer
elseif event.phase == “ended” or event.phase == “cancelled” then
holding = false
display.getCurrentStage():setFocus( event.target, nil )
event.target.isFocus = false
end
return true
end
local function gameLoop( event )
– Move player
local destX = nil
local destY = nil
if holding then
local radAngle = math.rad(angle) – Convert to radians
local lengthX = 30 * math.sin(radAngle)
local lengthY = -30 * math.cos(radAngle)
destX = round(player.x + lengthX, 0)
destY = round(player.y + lengthY, 0)
else
angle = nil
destX = nil
destY = nil
end
player.rotation = angle + 90 --Rotate the sprite to face the correct direction
local tileSolid = isSolid( player.level, destX, destY)
if tileSolid then
player:pause()
else
player:play()
mte.moveSpriteTo( { sprite = player, levelPosX = destX, levelPosY = destY, time = moveTime, easing = “linear” } )
end
else

end
