CurrentTouch.state == Click

Suggestions
1

Hello again,
I’ve a little problem with Codea. It’s about one time touch and double times click.
Here is a sample code:


function setup()
   watch("numberTap")
   numberTap = 0
end

function addTap()
   numberTap = numberTap + 1
end 

function draw()
   if CurrentTouch.state == BEGAN
      addTap()
   end
end

When I tap on the screen the variable numberTap is updated continuously not one time.
I think that the solution is:


if CurrentTouch.state == ClickPressed
      addTap()
   end

So, I suggest you to add: ClickPressed and ClickReleased.
I hope you understand my problem.

Edit: I do not know how to put this code here: don’t works. You know the codes for this forum?

The way I’ve been dealing with this is to keep track of touch state.<br

In setup, add a global oldState = nil

Then in your check loop do

if (CurrentTouch.state == BEGAN and oldState ~= CurrentTouch.state)

addTap()

end

Check for this instead


if CurrentTouch.state == ENDED and CurrentTouch.tapCount == 2 then
    performAction()
end

Mark, don’t works. Please give me an full example about One Simple Click.
Simeon, Your example works fine, but not works fine for One Simple Click and I know why, because function draw is updated every one frame, maybe, Here we need a function that is not automatically updated every frame, only if it interacted with touch event.

Does this help?

function touched(touch) is the separate way to handle touches you are looks for I think.

@Georgian: @Ipda41001 is correct, use the touched(touch) callback to handle touch events only when they occur and not every frame.

The state / oldState solution works, but you need to add oldState = CurrentTouch.state after the addTap() call.

Sorry I left that out

Many thanks to Ipda41001, HURRAY! it works! Sorry for this inconvenience, I will consult the Codea Documentation & Wiki.
