horizontal menu + gamepad
I'm making a horizontal selection menu and I would like the player to be able to select a spell from the menu using a gamepad.
I put this piece of code in the Update()
float moveHorizontal = Input.GetAxis ("Horizontal_P1");
Debug.Log ("moveHorizontal " + moveHorizontal);
if(Input.GetKeyDown (KeyCode.Q) || moveHorizontal == -1)
{
if(spellSelected > 0)
{
spellSelected --; // this changes the spell in mySpellSelected array
boxPosA --; // a "frame" GUIbox around the selected spell
}
}
if(Input.GetKeyDown (KeyCode.W) || moveHorizontal == 1)
{
if(spellSelected < 3)
{
spellSelected ++; // this changes the spell in mySpellSelected array
boxPosA ++; // a "frame" GUIbox around the selected spell
}
}
The problem is the "frame" GUIbox jumps from one side of the menu to the other very quickly, because it's updated every frame - that much I understand. Any ideas how to make the GetAxis behave like GetButtonDown instead of GetButton?
Use something like:
if (!received_input)
{
if (moveHorizontal < 0) moveSelectedLeft();
if (moveHorizontal > 0) moveSelectedRight();
received_input = true;
}
else if (moveHorizontal == 0)
received_input = false;
received_input ensures the player has to release the stick before moving the selection again. If they only need to release part-way, you could do:
...
else if (Mathf.Abs(moveHorizontal) < release_threshold)
received_input = false;
You could also use a timer to switch between "step-selection" (like above), and "rapid-selection" (like you already have), if the menus are fairly large, to make it easier for the player to cycle though the items.
