GetButton too slow

Unity Engine
1

Hello,

I would like to do a simple thing, but I can’t.
I want when the player push a button, he take an object. And when he push the same button, he put down the object.

    if(Input.GetButtonDown("Fire3") && haveObject == false){
        haveObject = true;
    }
    if(Input.GetButtonDown("Fire3") && haveObject == true){
        haveObject = false;
    }
    if(haveObject == true){
        portableObject.transform.position = transform.position;
    }

But when I push the button, he take the object and put it immediatly.
I think that’s because the button is still pushed for the second condition.

Someone have a solution pleaase ? :slight_smile:

Thanks in advance !

Mai oui! The value of Input.GetButtonDown() is not going to change between one line and the next. In fact, it will only change on the next frame.

Try this.

    if (Input.GetButtonDown("Fire3")) {
        haveObject = !haveObject;
    }
    if (haveObject){
        portableObject.transform.position = transform.position;
    }

Nice idea thanks. Yes I’m not yet used to thinking with frames :slight_smile:
So finally i can just write an else if instead of the second if.

Thank you so much :slight_smile:

Whenever you face an issue like this, you should work through your code line and by line and analyze the logic.

  • if a button is down and have object is false, set have object to true
  • if a button is down and have object is true, set have object to false
  • if have object is true, move the object

The error in logic should jump right out at you.

Yeh, but I use most often line by line compilation, like a “normal” program :slight_smile:
In the update function, it’s a little bit different and I’ve to get used to :slight_smile:
