thanks for your help

function scene:create( event ) local sceneGroup = self.view display.setDefault("background", 0.2 ) physics.start() physics.setGravity(0,90) physics.pause() --loading map local mapData = require("maps.level"..G.currentLevel) local map = tiled.new(mapData,"maps") sceneGroup:insert(map) map.x,map.y =0,0 --player nesnesi player=require ("player"); sceneGroup:insert(player) local mapPlayer=map:getObjectByName(map.layerGroups["player"],"objPlayer") player.x,player.y=mapPlayer.x,mapPlayer.y dpad=require "dpad" sceneGroup:insert(dpad) dpad:toFront()--dpad doesnt appear!!!!!!!!!!! --camera system camera = perspective.createView() camera:add(player, 1) camera:prependLayer() camera:add(map.layerGroups["sky"],4) camera:add(map.layerGroups["landBack"],3) camera:add(map.layerGroups["land"],2) camera:setParallax(1, 1, 1, 0.1) camera:setBounds(display.contentCenterX,map.designedWidth-display.contentCenterX-32, display.contentCenterY,map.designedHeight-display.contentCenterY) camera.damping = 10 camera:setFocus(player) camera:track() end

It looks to me like you’ve required the dpad module but not done anything else with it.

Normally you would have to call the module to create the object.

Without knowing which dpad module you’re using I couldn’t say how to initialise it.  Check the documentation that should have come with the module.

--dpad.lua local controlGroup = display.newGroup() local Dpad = display.newImageRect(controlGroup, "assets/images/control.png", 128, 32) Dpad.x = 80 Dpad.y = display.viewableContentHeight - 40 local jmp=display.newImageRect(controlGroup,"assets/images/jump.png",64,64) jmp.x = display.viewableContentWidth- 50 jmp.y = display.viewableContentHeight - 40 controlGroup.alpha=0.7 --event listener functions . . . return controlGroup

The require command loads the dpad module into memory but then it is not being called to do anything.  Where did you get the module from?  Can you post a link to it?
