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.

Hi there. Thanks for the articles, they are a great help.
I have a question about the getservice call. How fast is it? I see you are using it in your update functions a lot.

You don’t have to, I did just to make it clearer what we are doing.

Hi there and thanks for the great article! I have a question regarding this snippet from the InputDeviceEventArgs class:

this.State = ((InputDevice)Device).State;

why do we have to cast Device.State into InputDevice when it is already declared as of type InputDevice in the function arguments? Thanks in advance~
