Restart screen fail pt.2 .

I’m working on the restart screen for my app . I have a play button that is supposed to take me back to the game .it is displayed but when I press it it does nothing .however no error is displayed in the cmd prompt .

I had this error before and I was told to change everything to composer cause I had storyboard as well as composer .

level1.lua:

local composer = require( "composer" ) local scene = composer.newScene() local physics = require( "physics" ) physics.start() physics.setGravity(0, 40) -- display background image local background = display.newImage( "background.png" ) background.x = 10; background.y = 308 -- display ground image local ground = display.newImage( "ground.png" ) ground.x = 145; ground.y = 480 ground.myName = "ground" ground.isGround = true physics.addBody( ground, "static" , { friction=0.5, bounce=0.1 } ) -- create object local myObject = display.newRect( 0, 0, 100, 30 ) myObject:setFillColor( 0 ) myObject.x = 145; myObject.y = 400 myObject.isMyObject = true physics.addBody( myObject, "kinematic" , { myObject, friction=0.5, bounce=2 } ) -- touch listener function function myObject:touch( event ) if event.phase == "moved" then self.x = event.x self.y = event.y end return true end -- make 'myObject' listen for touch events myObject:addEventListener( "touch", myObject ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x, wall.y = -6, 387 wall.rotation = 90 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x, wall.y = -6, 300 wall.rotation = 90 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x, wall.y = -6, 202 wall.rotation = 90 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x, wall.y = -6, 104 wall.rotation = 90 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x, wall.y = -6, 7 wall.rotation = 90 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x, wall.y = 50, -49 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x, wall.y = 135, -49 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x = 232 wall.y = -49 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x = 335 wall.y = -49 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.rotation = 90 wall.x = 325 wall.y = 3 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.rotation = 90 wall.x = 325 wall.y = 98 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.x = 325 wall.y = 195 wall.rotation = 90 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.rotation = 90 wall.x = 325 wall.y = 292 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local wall = display.newImageRect( "wall.png", 100, 10 ) wall.rotation = 90 wall.x = 325 wall.y = 387 physics.addBody( wall, "static" , { wall, friction=0.5, bounce=0.5 } ) local block = display.newImage( "block.png" ) block.rotation = 8 block.x = 200 block.myName = "block" block.isBlock = true physics.addBody( block, "dynamic" , { block, friction=0.5, bounce=0.5 } ) local function onCollision( self, event ) local other = event.other if( event.phase == "began" and self.isBlock and other.isGround ) then timer.performWithDelay( 30, function() composer.gotoScene ( "restart", "fade", 500 ); end) self:removeEventListener( "collision" ) end return true end block.collision = onCollision block:addEventListener( "collision" ) local block2 = display.newImage( "block2.png" ) block2.rotation = 8 block2.x = 100 block2.isBlock2 = true physics.addBody( block2, "dynamic" , { block2, friction=0.5, bounce=0.5 } ) local function onCollision( self, event ) local other = event.other if( event.phase == "began" and self.isBlock2 and other.isGround ) then timer.performWithDelay( 30, function() composer.gotoScene ( "restart", "fade", 500 ); end) self:removeEventListener( "collision" ) end return true end block2.collision = onCollision block2:addEventListener( "collision" ) scene:addEventListener( "createScene", scene ) scene:addEventListener( "showScene", scene ) scene:addEventListener( "hideScene", scene ) scene:addEventListener( "destroyScene", scene ) return scene

restart.lua:

thank you for the help.

This is what the most basic composer scene looks like:

local composer = require( "composer" ) local scene = composer.newScene() -- ----------------------------------------------------------------------------------------------------------------- -- All code outside of the listener functions will only be executed ONCE unless "composer.removeScene()" is called. -- ----------------------------------------------------------------------------------------------------------------- -- local forward references should go here -- ------------------------------------------------------------------------------- -- "scene:create()" function scene:create( event ) local sceneGroup = self.view -- Initialize the scene here. -- Example: add display objects to "sceneGroup", add touch listeners, etc. end -- "scene:show()" function scene:show( event ) local sceneGroup = self.view local phase = event.phase if ( phase == "will" ) then -- Called when the scene is still off screen (but is about to come on screen). elseif ( phase == "did" ) then -- Called when the scene is now on screen. -- Insert code here to make the scene come alive. -- Example: start timers, begin animation, play audio, etc. end end -- "scene:hide()" function scene:hide( event ) local sceneGroup = self.view local phase = event.phase if ( phase == "will" ) then -- Called when the scene is on screen (but is about to go off screen). -- Insert code here to "pause" the scene. -- Example: stop timers, stop animation, stop audio, etc. elseif ( phase == "did" ) then -- Called immediately after scene goes off screen. end end -- "scene:destroy()" function scene:destroy( event ) local sceneGroup = self.view -- Called prior to the removal of scene's view ("sceneGroup"). -- Insert code here to clean up the scene. -- Example: remove display objects, save state, etc. end -- ------------------------------------------------------------------------------- -- Listener setup scene:addEventListener( "create", scene ) scene:addEventListener( "show", scene ) scene:addEventListener( "hide", scene ) scene:addEventListener( "destroy", scene ) -- ------------------------------------------------------------------------------- return scene

You should literally just copy and paste this into a file when you start a new scene. Notice that this template includes the (necessary) functions scene:create(), scene:show(), scene:hide() and scene:destroy(), which you have not included. Also notice the strings being passed in to event listeners at the end are diferent from what you have in your level1.lua (e.g “create” where you have “createScene”).

You should probably read here for further details:
