strange bug on iPhone with Even.MOUSE_DOWN with Event.MOUSE_MOVE

anneMurielle

Hi,

I'm modifying an old game for kid that I've made with Gideros in 2014. Everything seems to work fine except for 2 or 3 things.
I cannot figure one of them. In my game, I have several images that the kid can click on it to change the image or move the image (in this case, the image doesn't change).
Everything works fine with the player but when I launch the game on my iPhone I have a problem. Moving the image works fine but the simple click on these images doesn't work at all... except if I move the image at the bottom of the screen... so strange... what could be the problem? Do I need to add a plugin or a library in Xcode? ...

Thank you for your help!

I have 3 events for each of the images:
The Event.MOUSE_DOWN
The Event.MOUSE_MOVE
The Event.MOUSE_UP

In the mouse_up, I've added dialog to display what's the value of target.hasMoved... and on the iPhone, it's always true even if I just do a simple click.

Here is the code

MOUSE_DOWN-> set target.hasMoved to false

self.ball:addEventListener(Event.MOUSE_DOWN, function(event) local target = event:getTarget()   if target:hitTestPoint(event.x, event.y) then target.hasMoved = false self.ball.isMoving = true self.ball.x0 = event.x self.ball.y0 = event.y event:stopPropagation() end end )

MOUSE_MOVE-> move the object and change its scale depending on the position

self.ball:addEventListener(Event.MOUSE_MOVE, function(event) local target = event:getTarget()   if target.isMoving == true then target.hasMoved = true dx = event.x -target.x0 dy = event.y - target.y0 target.x0 = event.x target.y0 = event.y   local newX = dx + target:getX() local newY = dy + target:getY()   if newY + target:getHeight()/2 > application:getContentHeight() then newY =application:getContentHeight()-target:getHeight()/2 end   if newX +target:getWidth()/2> application:getContentWidth() then newX =application:getContentWidth()-target:getWidth()/2 end   if newY < -1*target:getHeight()/2 then newY =-1*target:getHeight()/2 end if newX < -1*target:getWidth()/2 then newX=-1*target:getWidth()/2 end   target:setX(newX) target:setY(newY)   --850 is the 1     local sc = 1*target:getY()/1156   if sc < 0.3 then sc = 0.3 end   if sc > 2 then sc = 2 end target:setScale(sc)       event:stopPropagation() end   end)

MOUSE_UP -> test the target.hasMoved, if false, remove the image and add the new one. But the problem is that the target.hasMoved is almost always true...

self.ball:addEventListener(Event.MOUSE_UP, function(event) local target = event:getTarget()   if (target.isMoving == true) then target.isMoving = false randomObject.ballX = target:getX() randomObject.ballY = target:getY()   if target.hasMoved == false then   self.ball:removeFromParent() self.ball = nil local i = randomObject.ball +1 randomObject.ball = i self:addBall(randomObject.ballX,randomObject.ballY) end target.hasMoved = false     event:stopPropagation()   end       end)

Use the code insert tag

Do you have these checkboxes enabled?

anneMurielle

Yes I have the same (two checkboxes enabled) and order Mouse, Touch

welcome back . You may need to add some tolerance to your click action because on mobile touch is very sensitive. Something like:

dx = event.x -target.x0 dy = event.y - target.y0 if math.abs(dx) >= 64 and math.abs(dy) >= 64 then target.ismoving = true end

Hope that helps?

Thank you for your help!

I added this test and adapted it because I change the scale if the object is on the top or bottom of the screen. Now that works well
