如何在C＃中使用Xbox 360按钮？

Question

I'm new to C Sharp, and writing a game w/ the XNA Framework.

I'm trying to establish variables for the buttons on the XBox 360 controller, so I can reconfigure the buttons' game functions in one place and not have to change direct references to the buttons everywhere.

So if I want to assign a button to "attack", instead of this:

if (gamePadState.IsButtonDown(Buttons.B)
{
   // do game logic
}

I want to do this:

if (gamePadState.IsButtonDown(MyAttackButton)
{
   // do game logic
}

Any ideas? I'm sure it's a very simple solution, but I've tried several approaches and none have worked yet. Thanks!

Answer 1

Buttons只是一个枚举，所以你只需要创建一个具有该名称的变量

Buttons MyAttackButton = Buttons.B;

Answer 2

An alternative would be to define an enum somewhere:

public enum MyButtons
{
    AttackButton = Buttons.B,
    DefendButton = Buttons.A
}

Then to test it:

if (gamePadState.IsButtonDown((Buttons)MyButtons.DefendButton))

Answer 3

You could also create a dictionary:

enum MyButtons { ShootButton, JumpButton }

Dictionary<MyButtons, Buttons> inputMap = new Dictionary<MyButtons, Buttons>()
{
    { MyButtons.ShootButton, Buttons.Y },
    { MyButtons.JumpButton,  Buttons.B },
}

...

if (gamePadState.IsButtonDown(inputMap[MyButtons.ShootButton]))
{
    // Shoot...
}

The advantage of this method is that the button map can be modified at runtime, so you can use it to implement customizable control settings.
