Property Value

MousePositionRaw is the mouse position relative to the game window - as it was read using the XNA Mouse class. MousePositionDeltaRaw is the mouse position change since the last frame. Both properties are read-only.

The properties MousePosition and MousePositionDelta are set to the same values as MousePositionRaw and MousePositionDeltaRaw in each frame. These properties have a setter and can therefore be modified by other game components. MousePosition and MousePositionDelta store any changed values for the rest of the frame. This is useful if the mouse position needs to be transformed. For example, the mouse position can be transformed to be relative to a viewport within the game window.

If MousePosition is modified, MousePositionDelta should be modified accordingly.
