How to stop an animation

[helloworld2013d]

I have this function

local function buttonBackHandler() -- A per-frame event to move the elements local tPrevious = system.getTimer() local function move(event) &nbsp;&nbsp; &nbsp;local tDelta = event.time - tPrevious &nbsp;&nbsp; &nbsp;tPrevious = event.time &nbsp;&nbsp; &nbsp;local xOffset = ( 0.1 \* tDelta ) &nbsp;&nbsp; &nbsp;funny1.x = funny1.x - xOffset &nbsp;&nbsp; &nbsp;funny2.x = funny2.x - xOffset &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;if (funny1.x + funny1.contentWidth) \< 0 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;funny1:translate( 1500, 0) &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;if (funny2.x + funny2.contentWidth) \< 0 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;funny2:translate( 1500, 0) &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp; end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- Start everything moving Runtime:addEventListener( "enterFrame", move );&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;return true end

It’s moving two images just fine…

but I need another button with a function inside to “Stop” the movement

I put this and it did not work

local function buttonHomeHandler()     move.stop()             return true end

Please help me out with this, I have a problem with sprites and with stop animation

this is the complete code

local storyboard = require( "storyboard" ) local widget = require "widget" local scene = storyboard.newScene() local buttonHome local buttonBack local funny1 local funny2 local function buttonHomeHandler() &nbsp;&nbsp; &nbsp;move.stop()&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;return true end local function buttonBackHandler() -- A per-frame event to move the elements local tPrevious = system.getTimer() local function move(event) &nbsp;&nbsp; &nbsp;local tDelta = event.time - tPrevious &nbsp;&nbsp; &nbsp;tPrevious = event.time &nbsp;&nbsp; &nbsp;local xOffset = ( 0.1 \* tDelta ) &nbsp;&nbsp; &nbsp;funny1.x = funny1.x - xOffset &nbsp;&nbsp; &nbsp;funny2.x = funny2.x - xOffset &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;if (funny1.x + funny1.contentWidth) \< 0 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;funny1:translate( 1500, 0) &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;if (funny2.x + funny2.contentWidth) \< 0 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;funny2:translate( 1500, 0) &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp; end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- Start everything moving Runtime:addEventListener( "enterFrame", move );&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;return true end -- --==\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*[CREATE SCENE]\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*++-- -- function scene:createScene( event ) &nbsp;&nbsp; &nbsp;local group = self.view&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;local background = display.newImage( "backgroundFunny.png" ) &nbsp;&nbsp; &nbsp;group:insert ( background ) &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;buttonHome = widget.newButton{ &nbsp;&nbsp; &nbsp;defaultFile="buttonHome.png", &nbsp;&nbsp; &nbsp;onRelease = buttonHomeHandler &nbsp;&nbsp; &nbsp;} &nbsp;&nbsp; &nbsp;group:insert ( buttonHome ) &nbsp;&nbsp; &nbsp;buttonHome.x = 910 &nbsp;&nbsp; &nbsp;buttonHome.y = 710 &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;buttonBack = widget.newButton{ &nbsp;&nbsp; &nbsp;defaultFile="buttonBack.png", &nbsp;&nbsp; &nbsp;onRelease = buttonBackHandler &nbsp;&nbsp; &nbsp;} &nbsp;&nbsp; &nbsp;group:insert ( buttonBack ) &nbsp;&nbsp; &nbsp;buttonBack.x = 100 &nbsp;&nbsp; &nbsp;buttonBack.y = 710 &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;funny1 = display.newImage( "funnyG1.png" ) &nbsp;&nbsp; &nbsp;funny1:setReferencePoint( display.CenterLeftReferencePoint ) &nbsp;&nbsp; &nbsp;funny1.x = 100; funny1.y = 200 &nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;funny2 = display.newImage( "carTireFront.png" ) &nbsp;&nbsp; &nbsp;funny2:setReferencePoint( display.CenterLeftReferencePoint ) &nbsp;&nbsp; &nbsp;funny2.x = 250; funny2.y = 200 end --------------------------------------------------------------ENTER SCENE---------- function scene:enterScene( event ) &nbsp;&nbsp; &nbsp; end -------------------------------------------------------------------------------------- --------------------------------------------------------------EXIT SCENE---------- function scene:exitScene() &nbsp;&nbsp; &nbsp; end -------------------------------------------------------------------------------------- -- --==\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*[DESTROY SCENE]\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*++-- -- function scene:destroyScene( event ) &nbsp;&nbsp; &nbsp;local group = self.view&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if buttonHome then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;buttonHome:removeSelf() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;buttonHome = nil &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if buttonBack then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;buttonBack:removeSelf() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;buttonBack = nil &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; end ---------------------------------------------------------------------------------- scene:addEventListener( "createScene", scene ) scene:addEventListener( "enterScene", scene ) scene:addEventListener( "exitScene", scene ) scene:addEventListener( "destroyScene", scene ) return scene

–Also, is there any function to move the images from left to right?

– And I found another problem. I have a button that will take me to another scene.

– I press that button and works fine.

– But if I have the images moving, when I use the button to go to another scene, I have an error.

File: …tormbarba/Desktop/How to make an app/speedSample.lua
Line: 31

Attempt to perform arithmetic on field ‘x’ (a nil value)

– Please I need help.

Thanks

You have 2 functions called “buttonHomeHandler”.   You have to change the name of one of them.

I changed the name, still is not working

Please help.

You have 2 functions called “buttonHomeHandler”.   You have to change the name of one of them.
