public KeyNodeLookDownAction(Spatial node, float speed)
KeyNodeLookDownAction
object
using the supplied node and speed for it's rotation. Speed is multiplied
by the time per frame, providing a frame rate independant speed. Thus,
speed should be considered in (unit/second).
node
- the node that will be affected by this action.speed
- the speed at which the node can move.Method Detail |

public void performAction(InputActionEvent evt)
performAction
rotates the node towards the nodes'
negative up axis at a speed of movement speed * time. Where time is the
time between frames and 1 corresponds to 1 second.
evt
- the event that triggered the perform action method.InputActionInterface.performAction(InputActionEvent)
