Silverlight 5 - XNA : Mouse.SetPosition

Question

I am using xna with silverlight 5 to build a 3d application.

Microsoft.Xna.Framework.Input.Mouse.SetPosition(10,10) is throwing the following exception

"The method or operation is not implemented."

Can someone confirm if the implementation is available for this method or am I missing something here...

Hi, I tried to reproduce your scenario, but I can't find Microsoft.Xna.Framework.Input namespace under Microsoft.Xna.Framework. But when I create an new Windows Phone Silverlight and XNA Application or Xbox 360 Game (4.0), It works now.

So I search it on MSDN, Microsoft.Xna.Framework.Input namespace is not available for Silverlight, but you can use it in Xbox Game or Windows Phone.

Thanks Johnson, I am trying to create a third person shooter with Silverlight and XNA.. The cross hair movement will be smoother if the mouse position can be set to center always.. and that is why I was looking at Mouse.SetPosition, and I see this cannot be done,

Any other recommendations that you are aware of which provides the same functionality ??

Hi,

Seems that you are building an game. I suggest you to install Microsoft XNA Game Studio and create a new project (Windows Game or Xbox 360 Game) which you can use XNA Framework and of course including Microsoft.Xna.Framework.Input.Mouse.SetPoint(,) method.

Or you can create a MyCrosshair Class represents the Crosshair which has X_Axis and Y_Axis properties, when the application is loaded, you can initialize its X_Axis and Y_Axis based on the Silverlight plugin size. (this is my own opinion)
