public class CustomChaseCamera
extends com.jme.input.ChaseCamera

Same original jME ChaseCamera with a different update method. Avoids getting updated by the main loop update method to avoid the sttutering. Adds a custom update method witch should be called after the physics update step.

Method Detail

getInstance

public static com.jme.input.ChaseCamera getInstance(com.jme.renderer.Camera camera,
                                                    Mission mission)

Factory method for initializing the ChaseCamera. Sets the initial properties for restricting ChaseCamera movement.

Parameters:

camera - to have the position updated.

target - to be followed.

Returns:

nextTarget

public void nextTarget()

Sets the chaser to follow the next target (tank). Since we mantain a collection of the possible targets for the chase camera we just have to iterate over this collection and find the next one.

update

public void update(float tpf)

Default empty update method that is invoked at the main loop. Overrides original for doing nothing to avoid sttutering.

Overrides:

update in class com.jme.input.ChaseCamera

Parameters:

tpf - time per frame

ChaseCameraUpdateCallback

customUpdate

public void customUpdate(float tpf)

Custom update method to be called after physics update step. Calls original update method, since after physics step is the safe moment to update the camera position.

Parameters:

tpf - time per frame
