Movement Button Problem
Posted on Tue, 2012-02-07 15:16
Hello Community, I have a problem with my movement buttons; I have two buttons (Button Left and Button Right), I've added a "touch" listener to both buttons, and the multitouch is enable. When the "touch" starts the character moves to the indicated direction, and when the "touch" is ended the character is stopped; but here's the problem: sometimes the character continues moving to any direction and doesn't stop when I release the button.

Also you would want to have this at the end of your function.
1 | return true |

@peach Yes, when e.phase "ended" = stop
@danny I tried it, but nothing happens

Hi :)
Can you strip the part in question down to an example/sample and post up the code?
I'm sure its something simple :)

Yes, here's the code, but in this code I changed the button's listeners to a Runtime listener, you can see here, that if you touch inside a specific part of the screen you can move the character to right or left, but when I use the buttons (not the Runtime listener) I'm getting problems.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 | --Multitouch is Activated --Buttons are in the left corner and right corner from the screen (down) local buttonLeft = display.newImage ( "button.png" ) buttonLeft:addEventListener ( "touch", moveLeft ) local buttonRight = display.newImage ( "button2.png" ) buttonRight:addEventListener ( "touch", moveRight ) --Checking if Movement to Right is true function moveRight (e) if ( gameplay == true ) then if ( e.phase == "began" ) then motionRight = true elseif ( e.phase == "ended" ) then motionRight = false end end return true end --Checking if Movement to Left is true function moveLeft (e) if ( gameplay == true ) then if ( e.phase == "began" ) then motionLeft = true elseif ( e.phase == "ended" ) then motionLeft = false end end return true end --Movement Setup ( Fixing the double touch ) function movement () if ( gameplay == true ) then if ( motionRight == true and motionLeft == false ) then motionX = speedX elseif ( motionRight == false and motionLeft == true ) then motionX = -speedX elseif ( motionRight == true and motionLeft == true ) then motionX = 0 elseif ( motionRight == false and motionLeft == false ) then motionX = 0 end end end Runtime:addEventListener ( "enterFrame", movement ) --Group Movement ( Player ) function groupMove () if ( gameplay == true ) then player.x = player.x + motionX end end Runtime:addEventListener ( "enterFrame", groupMove ) --Player Wrap function playerWrap () if ( gameplay == true ) then if ( player.x < 150 ) then player.x = 150 elseif ( player.x > wScreen - 25 ) then player.x = wScreen - 25 end end end Runtime:addEventListener ( "enterFrame", playerWrap ) |

This code works? Do you have the code that doesn't work?

The code that doesn't work is the same, just replace the "Runtime Listener touch-moveLeft" and "Runtime Listener touch-moveRight" to two button listeners ("ButtonLeft Listener touch-moveLeft" and "ButtonRight Listener touch-moveRight") and erase the "e.x" and "e.y" conditions inside moveLeft and moveRight functions.

I changed the "e.x" and "e.y" coordinates (to a area of 50X50 pixels) to simulate the area of the buttons but I have the same problem, the problem doesn't exist just when I use the huge area.

Can you post the full code with button source just to humour me? :)

Ready, the code above is the code that doesn't work. The problem is that my character sometimes doesn't stop when I release the button and continues its movement.

I wonder if you need to test for "cancelled" as well...

eg:
1 | elseif ( e.phase == "ended" or e.phase == "cancelled") then |

@Danny Yeah, I think that's the problem, but I could not fix it. The parameters to "ended" the touch when I release it outside the buttons don't work. Sorry Danny, can you help me with that? I tried this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | --Checking if Movement to Right is true function moveRight (e) if ( gameplay == true ) then if ( e.phase == "began" ) then motionRight = true elseif ( e.phase == "ended" ) then motionRight = false if ( e.x > buttonRight.contentBounds.xMin and e.x < buttonRight.contentBounds.xMax and e.y > buttonRight.contentBounds.yMin and e.y < buttonRight.contentBounds.yMax ) then motionRight = false end end end print ( motionRight ) end |
Do you have an ended phase on your buttons?
