MOUSE Category

Nodes for reading mouse button state, scroll wheel, and cursor position. Complement the CURSOR category.

Available Nodes

Node	Type	Description
Mouse Button	Branch	Detects left, right, or middle click
Mouse Scroll	Branch	Detects scroll wheel up or down
Mouse Position	Data	Returns cursor X or Y position
Mouse Over	Branch	Detects whether cursor is over a 3D object
Mouse Raycast	Branch	Ray from camera to cursor with hit result

Difference between Mouse Over and Cursor Over

Both nodes cast a ray from the camera to the cursor, but Mouse Over (in mouse_nodes.py) uses getScreenRay directly and exposes the hit object as a result. Cursor Over (in cursor_nodes.py) uses a similar approach but allows filtering by BGE property or specific object name.
