我是这个论坛的新手,只是为了问这个具体的问题而注册:我一直在关注视频游戏开发的YouTube网络系列(如何制作2D游戏 - 由EddieVanHalen98制作)但他没有告诉我如何让相机跟随特定的精灵.

我的渲染代码如下

public class [ClassName] {
    polkymain game; 
    OrthographicCamera camera;

    public static int PolkyX;
    public static int PolkyY;

    SpriteBatch batch;

    public GameScreen(polkymain game){
        this.game = game;

        camera.setToOrtho(true, 1280, 1240);

        batch = new SpriteBatch();

        PolkyX = 0;

        Gdx.gl.glClearColor(0.95F, 0.95F, 0.95F, 0.95F);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);       

        camera.update();
        generalUpdate();

        batch.setProjectionMatrix(camera.combined);     
        batch.begin();          
        batch.draw(Assets.Sprite_Mario_main, PolkyX, PolkyY);       
        batch.end();
    }

    public void generalUpdate(){
        if(Gdx.input.isKeyPressed(Keys.D) || (Gdx.input.isKeyPressed(Keys.LEFT))
        {
            PolkyX += 5;
        }

        if(Gdx.input.isKeyPressed(keys.A) || (Gdx.input.isKeyPressd(Keys.RIGHT)) …
