Function Documentation

void LinkToGLUT

(

InputSystem &

system

)

Links an InputSystem to the GLUT window system.

This function can be called to initialise the GLUT callbacks to refer to all the appropriate member functions of an InputSystem object.

For example, the glut mouse functions will trigger the InputSystem's mouseDown, mouseUp and other methods after the InputSystem is linked to GLUT.

Note that this function links an InputSystem to GLUT using an inverted Y axis. So the resulting window coordinates received by the InputSystem will be relative to the lower left corner of the screen. That is, the lower left corner will represent (0, 0) and the upper right corner will represent (window_width, window_height).
