[Game AI][Steering Behavior] 17. Task_Seek (test.SeekScenario )

test.SeekScenario 

 

- 수정해야할 부분 

GameObject car2 = new Car("graphics/bluecar.png",600,300,-Math.PI/2, new EmptyController());

GameObject car2 = new Car("graphics/bluecar.png", 600, 300, -Math.PI / 2, new SeekController(car1));

 

위에 있는 코드를 아래처럼 바꾸면 된다. 

EmptyController() 대신 우리가 만든 SeekController(car1)을 추가해주는 것이다. 

여기서 car1은 car2가 추적해야되는 대상을 나타낸다. 

SeekController는 이 정보를 사용해서 car2가 car1을 추적하도록 만들 수 있다. 

(해당 자동차를 추적하고, 그 자동차를 향해 움직이도록 하는 것)
