Turns out that if I am doing the

if (keyboard.IsKeyDown(Keys.Up) || gamepad.IsButtonDown(Buttons.DPadUp))
InputCommand = “moveUp”;

stuff in the Game.Update() Method, everything works fine. It just doesn’t work in my GameScreen.HandleInput() (which is called from the GameScreen.Upate() ). That’s weird, because there aren’t any such problems with the Keyboard…

Addition: Copy & Paste maluse makes it seem I do the initialization after the registration. This is not the case. the gamepad = new …. comes at the very first.

I can’t seem to get the gamepad to work on my XBox. I have a HandleInput method like this:

public void HandleInput()
{
KeyboardDevice kbd = (KeyboardDevice)
Engine.Services.GetService(typeof(KeyboardDevice));
GamepadDevice gpd = (GamepadDevice)
Engine.Services.GetService(typeof(GamepadDevice));

if (kbd.IsKeyDown(Keys.Up) || gpd.IsButtonDown(Buttons.DPadUp))
inputString = “moveUp”;

Using the keyboard on the PC works just fine. The gamepad for the XBox is dead…

Here is how I register the input devices in my Game Class:

engine = new Engine(graphics);
engine.Services.AddService(typeof(KeyboardDevice), keyboard);
engine.Services.AddService(typeof(GamepadDevice), gamepad);
keyboard = new KeyboardDevice();
gamepad = new GamepadDevice(PlayerIndex.One);
MyGameScreen.AddComponent(keyboard);
MyGameScreen.AddComponent(gamepad);

What am I missing?

I am running up to this chapter on the 360. Works like a charm. Except that when I “fire” it adds the last of the 9 boxes and knocks them over.

Also when I “fire” alot of boxes I get a performance drop really fast.
Is this caused by the physics?

boxes spawn inside eachother so I guess it causes quite some collisions?

It’s fast enough that you don’t have to worry about how fast it is

It’s pretty much just calling the retrieve function in a dictionary contained in Engine.Services.
