Touch event not ending when no longer over object

Solar2D General Questions/Discussion
#1

I have an event listener attached to an object. I want the event to be fired when the user touches the object, then I want to return the distance when the user drags his finger off the object and lifts it from the screen. I calculate the distance using event.x and event.xStart (and y ) upon event “ended”.

The problem is that if the user drags his finger off of the object before lifting it from the screen, nothing happens. How can I start the event when the object is hit and end it when the finger is lifted even when it is no longer on the object? [import]uid: 3018 topic_id: 2670 reply_id: 302670[/import]

If you set the evenlistener to “tap” and not “touch” it starts when you touch it.

As is shown in the many examples in the SDK and the docs, you need to lock the focus on to the object being touched:

display.getCurrentStage():setFocus(object)

Then catch the “moved” events and check the position of the touch as you’re doing now. Remember to setFocus(nil) in the “ended” and “cancelled” phases. [import]uid: 3953 topic_id: 2670 reply_id: 7820[/import]

Here is some code from their example:

 -- Subsequent touch events will target button even if they are  
 -- outside the stageBounds of button  
 display.getCurrentStage():setFocus( self )

If I set the focus to the object, shouldn’t it return “ended” even when it is ended no longer touching the event? It doesn’t [import]uid: 3018 topic_id: 2670 reply_id: 7935[/import]

It returns “ended” when the touch ends; that is, when you lift the mouse or finger. Put this in your code at the beginning of your handler & it will become clearer:

print(event.phase) [import]uid: 3953 topic_id: 2670 reply_id: 7978[/import]

#7

This line does not work for Android:

display.getCurrentStage():setFocus( self )

Does anyone know a work-around? [import]uid: 29652 topic_id: 2670 reply_id: 26331[/import]
