Input.GetKeyUp for Axis input
Hello everyone,
the situation is that i need the player to jump after the space key is released, so this works perfectly
if (Input.GetKeyUp (KeyCode.Space)) {
//do stuff
}
but i need to use custom input instead, i tried doing this :
if (Input.GetAxisRaw("P1Jump")==0) {
//do stuff
}
however the result was obviously the player jumping all the time, what i don't understand is why when i print GetKeyUp i always get false but it is only triggered when i actually press and release the key, but when the Axis Raw it is always zero and it's always calling doing something
thank you
Make sure to set your axis type to "KeyOrMOuseButton"
Then read it using Input.GetButtonUp
http://docs.unity3d.com/Documentation/ScriptReference/Input.GetButtonUp.html
It will not return true until the user has pressed the button and released it again.
This is just how it works. GetKey goes through a cycle of states :
Idle
pressed Down
Held down
released Up
So GetKeyUp is only true after being held down then released, not if it is idle.
You could emulate an axis behaving like a button like this :
#pragma strict
enum AxisState
{
Idle,
Down,
Held,
Up
}
var axisState : AxisState;
var deadZone : float = 0.02;
function Update()
{
switch ( axisState )
{
case AxisState.Idle :
if ( Input.GetAxis( "Horizontal" ) < -deadZone || Input.GetAxis( "Horizontal" ) > deadZone )
{
axisState = AxisState.Down;
}
break;
case AxisState.Down :
axisState = AxisState.Held;
break;
case AxisState.Held :
if ( Input.GetAxis( "Horizontal" ) > -deadZone && Input.GetAxis( "Horizontal" ) < deadZone )
{
axisState = AxisState.Up;
}
break;
case AxisState.Up :
axisState = AxisState.Idle;
break;
}
Debug.Log( axisState );
}
in your example, to check for an axis up state would be :
if (axisState == AxisState.Up) {
//do stuff
}
