On button release

Engines, Libraries and Tools JInput
#1

I couldnt find a method for on button release. Im using this so the user can hold down a button and it wont register it XX amount of times due to the refresh rate of the event loop. Thanks.

#2

What are you using? LWJGL, etc…?

#3

Oh sorry, im using the newest build of JInput.

A way to do it:

Have a boolean buttonPressed which you set to true if the button is pressed.
If the boolean changes from true to false you know the user released the button.

#5

But if i say if buttonPressed == false, that would be all the time that it isnt pressed not just after it is pressed. Thanks though

#6 

boolean lastTimeButtonPressed = buttonPressed;
buttonPressed = checkIfButtonIsPressed();

if(lastTimeButtonPressed && !buttonPressed) {
    System.out.println("The button has been released");
}
#7

Ok thanks :smiley: but you would have to set buttonPressed to false in that otherwise it would keep going.

#8 
boolean lastTimeButtonPressed = buttonPressed;
buttonPressed = checkIfButtonIsPressed();

if(lastTimeButtonPressed && !buttonPressed) {
    System.out.println("The button has been released");
    buttonPressed = false;
}
#9

No, buttonPressed would already be false or it couldn’t get through the if statement.

#10 

boolean buttonPressed = false;
boolean lastButtonPressed = false;

In update method


buttonPressed = checkIfButtonPressed();

if(lastButtonPressed && !buttonPressed){
     System.out.println("Button Released");
}

lastButtonPressed = buttonPressed
#11

sorry i meant to put lastbuttonpressed should be false

and also can someone help explain why i get different results for these thanks:
This works:

 
if (Controllers.isCirclePressed() == true) {circlePressed = true;}
if (Controllers.isCirclePressed() == false && circlePressed == true)
    {
         if (jAutonomyBox.isSelected()) {jAutonomyBox.setSelected(false);}
         else {jAutonomyBox.setSelected(true);}
         circlePressed = false;
     }

but if i use

circlePressed = Controllers.isCirclePressed();

instead of if(Controllers.isCirclePressed() == true)… it never gets called.
