Question

Here is my trouble.

• When the button is off it hase value 0.
• When it is pressed it turns to 1.
• When it is released it gets back to 0.

Now I was using the following code to listen to change event:

if (obj[0].state.A === 1) {
    //do some thing
}

The problem is I have the function that wraps around my code.
It is TICK function which resets $obj.state.A to 0 if it is not pressed.
It ticks every 0.10ms.

Now here is where the problem is, $if (obj[0].state.A === 1) gives my code that executes when the button is down.
But I need to make it happen on button up! event and only once in one press.

How do I do that?

I found it!

This is how I did it:

if (gamepads[0].state.A === 1 && this.lastStateA == 0) {
      //do stuff
}
this.lastStateA = gamepads[0].state.A;
