Returns:: The coordinate being looked-at by this camera.
Overrides: core.Camera'.Camera.getLookAt: (inherited documentation)

getPosn(self)

Returns the position coordinate of this camera.

Returns:: Position coordinate of this camera.
Overrides: core.Camera'.Camera.getPosn: (inherited documentation)

getZoom(self)

Returns the zoom factor.

Returns: float: The zoom factor.
Overrides: core.Camera'.Camera.getZoom: (inherited documentation)

setLookAt(self, lookAt)

Sets the coordinate at which this camera is looking.

Parameters:

coord - New coordinate to be looked-at by this camera.

Overrides: core.Camera'.Camera.setLookAt

(inherited documentation)

setPosn(self, posn)
