Move-Out / Move-In Touch Event

Solar2D General Questions/Discussion
#1

I have a button that sets a variable to n when touched and back to 0 when un-touched. I have the basic code working but the problem is that when the button is touched, then the finger is moved out of the button, no ended event is triggered, so the variable is never set back to 0, which messes up my game. I’m asking if there is anyway to detect if a touch event moves out of the target’s bounding box.

Also, I realize that I can setup a global touch listener and check if the point of the touch event hits the button, but there a lot of buttons and it would get laggy and really hard to code.

This might be what you are looking for;

display.getCurrentStage():setFocus( self )

–Here is how it is used.
function button:touch( event )
local phase = event.phase
if “began” == phase then
– Subsequent touch events will target button even if they are
– outside the stageBounds of button
display.getCurrentStage():setFocus( self )
else
…
end

return true

It didn’t work. Still behaves the same. Here is my code:

[code]
function tapButton(event)
if(event.phase == “began”) then
n = 100
display.getCurrentStage():setFocus(self)
end
if(event.phase == “ended”) then n = 0 end
end

button:addEventListener(“touch”, tapButton)
