Check whether screen is being touched at a given time?

[neo187]

Hi all

This is not strictly a JPCT query but rather an Android programming one....but I can't seem to find any info on this and maybe someone has come across this same issue.

I am currently using onToucheEvent to register all kinds of touch inputs... In my game I am using both ACTION_DOWN and ACTION_UP to trigger certain events....

Sometimes a frame rate  drop can lead the application to not detect an ACTION_UP event following and ACTION_DOWN, so for actions where holding down a button and then releasing it make stuff happen this becomes problematic...

Is there a way to get round this issue? Basically a way to check at any time whether there is a finger on the screen or not, so as to make up for lost touch.up events?

Thank you very much

First, check that your OntouchEvent() always return true or it will only get the ACTION_DOWN event.

If it's not this, the problem is that ActionEvents only fire when there is a change. (You can't check a NO_ACTION event then)
So maybe you could use a Timer...

Thanks Vi_O! That seems to have done the trick actually! I needed to have a statement for ACTION_CANCEL which I didn't and I needed to make sure to always return true.... Following the HelloWorld template I was actually returning super.onToucheEvent... Now at a slow framerate the ACTION_UP may register with a bit of a delay but from a small test it seems to always register.

Thanks again!
