iTestBed::setCameraControlState()

Description

Set control state for built in testbed controls, based on mouse movement.

Syntax

void setCameraControlState(int32_t state);

Parameters

Remarks

Control state is set on a frame by frame basis and if this method is not called on a given update frame the control state will revert to PE_CameraControl_None.

Possible values for state are as follows:

PE_CameraControl_None - no camera controls are applied.

PE_CameraControl_Zoom - camera moves in or out from current camera target, mouse movement to left zooms out, mouse movement to right zooms in.

PE_CameraControl_Pan - mouse movement left, right, up or down moves camera target such that the world appears to move in the same direction.

PE_CameraControl_Rotate - two angle rotation of camera position around current target, relative to the world Z axis (left right movement spins around this axis, up down movement controls elevation).

If a world position is supplied, with iTestBed::setCameraControlTarget(), this will be used to adjust camera target position in certain cases to avoid the camera target getting 'locked' at arbitrary locations and help ensure that camera control remains intuitive.
