Input.GetButtonUp ?

Questions & Answers
1

I want to press a button and detect if this has happened as soon as I pressed the button.
These functions only detect a key press if I release the button and both seem to be the same?

Input.GetButtonUp or Input.GetButtonDown

void Update () {
	  if (Input.GetButtonDown("Jump"))         
	{
		Debug.Log("Space bar pressed");
	}
		
	

}

GetButtonDown only returns true during the frame when the button is pressed down. GetButtonUp only returns true during the frame when the button, which had previously been pressed, is released.
