Hey, i started learning corona sdk by making a space invaders game on this tutorial : http://code.tutsplus.com/tutorials/create-a-space-invaders-game-in-corona-implementing-gameplay–cms-22788
i wrote the same code but it doesn’t work, it gives me an error.
the start.lua file is:
local composer = require( "composer" ) local scene = composer.newScene() local startButton -- used to start the game local pulsatingText = require("pulsatingtext") -- A module providing a pulsating text effect local starFieldGenerator = require("starfieldgenerator") -- A module that generates the starFieldGenerator local starGenerator -- An instance of the starFieldGenerator function scene:create( event ) local group = self.view startButton = display.newImage("new\_game\_btn.png",display.contentCenterX,display.contentCenterY) group:insert(startButton) local invadersText = pulsatingText.new("INVADERZ",display.contentCenterX,display.contentCenterY-200,"CONQUEST", 20,group) invadersText:setColor( 1, 1, 1 ) invadersText:pulsate() end function scene:show( event ) local phase = event.phase local previousScene = composer.getSceneName( "previous" ) if(previousScene~=nil) then composer.removeScene(previousScene) end if ( phase == "did" ) then startButton:addEventListener("tap",startGame) end end function scene:hide( event ) local phase = event.phase if ( phase == "will" ) then startButton:removeEventListener("tap",startGame) end end function startGame() composer.gotoScene("gamelevel") end scene:addEventListener( "create", scene ) scene:addEventListener( "show", scene ) scene:addEventListener( "hide", scene ) return scene
and the pulsatingtext.lua file is:
local composer = require( "composer" ) local scene = composer.newScene() local pulsatingText = {} local pulsatingText\_mt = {\_\_index = pulsatingText} function pulsatingText.new(theText,positionX,positionY,theFont,theFontSize,theGroup) local theTextField = display.newText(theText,positionX,positionY,theFont,theFontSize) local newPulsatingText = { theTextField = theTextField} theGroup:insert(theTextField) return setmetatable(newPulsatingText,pulsatingText\_mt) end function pulsatingText:setColor(r,b,g) self.theTextField:setFillColor(r,g,b) end function pulsatingText:pulsate() transition.to( self.theTextField, { xScale=4.0, yScale=4.0, time=1500, iterations = -1} ) end return pulsatingText return scene
i upload an image with the error i am getting.
thanks for your help!
