Hey guys I am building an app so when the enemy collides with your “boat” then you lose and it will change scene.I have it so when the boat detects collision it will call the function but it only calls the “print” and it wont call the “composer.gotoScene(”")" or anything else inside.
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 local physics = require ("physics");
