Animating and Moving the Robot

• In DemoFrameListenerframeStarted
• There are three items that we have to do.
• Animate the robot according to the state of the
  robot
• idle and walk
• 2. Translate the robot from one location to
  another location
• using interpolation method.
• 3. If the facing direction of the robot is not
  consistent
• with the walking direction, the orientation
  of the robot
• should be changed.

Animating the robot based on its state
Set state AnimationState mAnimationState mAnima
tionState mEntity-gtgetAnimationState("Idle") mA
nimationState-gtsetLoop(true) mAnimationState-gtset
Enabled(true) Animate mAnimationState-gtaddTime
(evt.timeSinceLastFrame) Remark use
OgreMeshViewer and view the mesh
