ModifyMouseState

Introduction

The ModifyMouseState event is an event you can add to the Mouse object to set/modify the Microsoft.Xna.Framework.Input.MouseState used by the mouse for positioning and clicking. This is useful if you are working on a platform which does not have mouse input but you would like to simulate mouse input, or if you are working on a platform which requires modifications of the mouse input.

Code Example

The following code can be used in a WPF project to properly set the mouse position. Add the following to your Game's Initialize function:

FlatRedBall.Input.Mouse.ModifyMouseState += HandleModifyMouseState;

Add the following implementation:

private void HandleModifyMouseState(ref Microsoft.Xna.Framework.Input.MouseState mouseState)
{
    var point = Control.MousePosition;

    var screen = mFrbControl.PointFromScreen(new System.Windows.Point(point.X, point.Y));
    var newMouseState = new Microsoft.Xna.Framework.Input.MouseState(
        MathFunctions.RoundToInt(screen.X),
        MathFunctions.RoundToInt(screen.Y),
        mouseState.ScrollWheelValue,
        mouseState.LeftButton,
        mouseState.MiddleButton,
        mouseState.RightButton,
        mouseState.XButton1,
        mouseState.XButton2);
    mouseState = newMouseState;
}
