Detailed Description

This simple engine extends the base class vtEngine with the ability to remember the last state of the mouse. This is useful for engines which simply need to know mouse state (cursor position and button state). They can simply subclass from vtLastMouse and use the inherited fields rather than having to catch mouse events.

Member Function Documentation

void vtLastMouse::GetNormalizedMouseCoords	(	float &	mx,
		float &	my
	)

Returns the mouse coordinates in the window, normalized such that X and Y range from -1 to 1 (left to right, top to bottom across the window.

Member Data Documentation

int vtLastMouse::m_buttons

The state of the mouse buttons

int vtLastMouse::m_flags

Last known state of the modifier flags

IPoint2 vtLastMouse::m_pos

The location of the mouse cursor
