背景信息

嘿，伙计们，我目前正在开发一个小rpg:）今天我尝试实现一些简单的灯光

主要问题

当我在项目中使用点光源时，fps将变得越来越慢。。。我有一台非常好的电脑，所以它不可能是我的gpu或cpu。。。我错过了什么

这是一张截图

您可以在左下角看到fps:6。顺便说一下，我禁用了vsync，我的gpu是GTX960。。。所以我真的不知道为什么我的fps这么低

球员级别：

package Mobs;


public class Player {

AnimatedSprite animatedSprite;
SpriteBatch batch;

Light licht = new Light(Color.WHITE,500);


public int state = 0;
public int netState = 1;
float speed = 2f;
public Vector2 position = new Vector2(256,256);
public Vector2 networkPosition = new Vector2(0,0);



public Player(){



}


public void update(){

       state = 0;

       if(Gdx.input.isKeyPressed(Keys.A)){ 
           position.x -= Gdx.graphics.getDeltaTime() * 100f;


           state = 1;
           //System.out.println(currentState);
       }
       if(Gdx.input.isKeyPressed(Keys.D)){
           position.x += Gdx.graphics.getDeltaTime() * 100f;    


           state = 2;
           //System.out.println(currentState);
       }
       if(Gdx.input.isKeyPressed(Keys.W)){ 
           position.y += Gdx.graphics.getDeltaTime() * 100f;


           state = 3;
           //System.out.println(currentState);
       }
       if(Gdx.input.isKeyPressed(Keys.S)){ 
           position.y -= Gdx.graphics.getDeltaTime() * 100f;


           state = 4;
           //System.out.println(currentState);
       }



}

public void setX(float x){

    position.x = x;

}

public void setY(float y){

    position.y = y;

}

public void draw(float f, float g, OrthographicCamera camera){

    position.x = f;
    position.y = g;

    //System.out.println("In beforeSetState : "+currentState);
    animatedSprite.setState(state);
    //System.out.println("In after : "+currentState);
    animatedSprite.createAnimation();

    camera.position.set(f,g,0);
    camera.update();

    licht.drawLight(camera, f+25 , g+25);


    batch.setProjectionMatrix(camera.combined);
    batch.begin();
    batch.draw(animatedSprite.convertAnimationTOframes(),f,g, Gdx.graphics.getWidth()/25,Gdx.graphics.getHeight()/15);   
    batch.end();



}


public void doSetup(){


    batch = new SpriteBatch();
    animatedSprite = new AnimatedSprite();


}



public float getX(){


    return position.x;


}

public float getY(){


    return position.y;


}

my Main类中的.doDispose（）是从使用的类中处理资源的方法

感谢您的帮助和时间：）

如果您没有处理任何东西，您可能需要查看LibGDX的dispose（）函数这里是链接

如果这不是问题，请告诉我们。

什么是

player.createFixture（PolyConfigure）做什么？它将一个box2d动态对象附加到播放器：）Thx为了查看我的代码，我通常不会得到答案没有问题。你介意用包含的代码编辑你的帖子吗？仅供参考，我是在这样的假设下运行的，即您在每个绘制周期中都在不断地创建资源，而不是释放它们。这将导致渲染速度减慢，因为它必须绘制越来越多的图形。我正在尝试定位可能发生这种情况的位置。我可以删除该部分，因为它仅在附加的屏幕上“绘制”一个动态多边形：）问题在于灯光。您可以尝试暂时删除该代码并检查性能吗？另外，在你的代码中，你是否看到你正在创建可以呈现的对象？啊，这就是我在帖子评论中所想的答案。这是一个很好的发现，确实如此，更新了我的代码：），但仍然有延迟，比如每3-5秒一次：/可能是因为我的渲染方法？
