Method Detail

### interact

    void interact(java.util.ArrayList<IDynamics> dynamics)

  behavior definition of interaction with other dynamic objects. The server puts all dynamic objects including itself.

### update

    void update()

  behavior definition of updating dynamics in each time frame

### preinteract

    void preinteract(java.util.ArrayList<IDynamics> dynamics)

  executed before interact(ArrayList). behavior can be changed by IConfig.enablePreinteract and IConfig.loopPreinteract.

### postinteract

    void postinteract(java.util.ArrayList<IDynamics> dynamics)

  executed after interact(ArrayList). behavior can be changed by IConfig.enablePostinteract and IConfig.loopPostinteract. If IConfig.loopPostinteract is false, preupdate is executed before post interact (updated 2012/08/26).

### preupdate

    void preupdate()

  executed before update(). behavior can be changed by IConfig.enablePreupdate and IConfig.loopPreupdate. If IConfig.loopPreupdate is false, preupdate is executed before post interact (updated 2012/08/26).

### postupdate

    void postupdate()

  executed after update(). behavior can be changed by IConfig.enablePostupdate and IConfig.loopPostupdate.

### localDynamics

    java.util.ArrayList<IDynamics> localDynamics()

  IDynamics can have local dynamics which is managed by parent dynamics. IAgent implements this feature

### target

    IDynamics target(IObject targetObj)

  add terget object to be updated by this dynamic object.

### targetNum

    int targetNum()

  get total target number.

### target

    IObject target(int i)

  get target object.

### targets

    java.util.ArrayList<IObject> targets()

  get all target objects.

### removeTarget

    IDynamics removeTarget(int i)

  remove target object.

### removeTarget

    IDynamics removeTarget(IObject obj)

  remove target object.

### updateTarget

    void updateTarget()

  update all terget objects (should be called when the dynamic object is updated).
