libgdx：为什么我的自定义actor有内存泄漏？

Question

我创建了以下自定义actor以在libgdx上绘制线条

public class LineWidget extends Actor implements Disposable {

private Position posA;
private Position posB;

public final Vector2 _A;
public final Vector2 _B;

private TextureRegion lineTexture;
private final TextureRegion lineTextureGreen = Assets.instance.Images.lineGreen;
private final TextureRegion lineTextureOrange = Assets.instance.Images.lineOrange;
private final TextureRegion lineTextureRed = Assets.instance.Images.lineRed;

public LineWidget(Position A, Position B) {
    this._A = A.getPositionVector();
    this._B = B.getPositionVector();
    this.posA = A;
    this.posB = B;
}

@Override
public void act(float delta) {
    super.act(delta);
}

@Override
public void draw(Batch batch, float parentAlpha) {
    super.draw(batch, parentAlpha);

    setLineColor(posA, posB);

    float xdif = _B.x-_A.x;
    float ydif = _B.y-_A.x;
    float l2 = xdif*xdif+ydif*ydif;
    float invl = (float)(1/Math.sqrt(l2));
    //dif is vector with length linewidth from first to second vertex
    xdif*=invl*5;
    ydif*=invl*5;

    float floatBits = batch.getColor().toFloatBits();
    //draw quad with width of linewidth*2 through (x1, y1) and (x2, y2)
    float[] verts = new float[]{_A.x+ydif, _A.y-xdif, floatBits, lineTexture.getU(), lineTexture.getV(),
            _A.x-ydif, _A.y+xdif, floatBits, lineTexture.getU2(), lineTexture.getV(),
            _B.x-ydif, _B.y+xdif, floatBits, lineTexture.getU2(), lineTexture.getV2(),
            _B.x+ydif, _B.y-xdif, floatBits, lineTexture.getU(), lineTexture.getV2()};
    batch.draw(lineTexture.getTexture(), verts, 0, 20);
}

@Override
public void setSize(float width, float height) {
    super.setSize(width, height);
}

@Override
public void dispose() {
}

private void setLineColor(Position A, Position B) {
    if(A.get_value() != null && B.get_value() != null) {
        if(A.get_value() == 1 || B.get_value() == 1) {
            lineTexture = lineTextureGreen;
            return;
        }else {
            lineTexture = lineTextureRed;
        }
    } else {
        lineTexture = lineTextureRed;
    }
}

}

当我创建演员时，内存消耗不断上升，但我无法检测到这种泄漏发生的位置。如何修复此actor以阻止内存泄漏？

编辑：我在另一个扩展了Group Actor类的actor中绘制了这个actor。组actor类不泄漏内存，它现在唯一要做的就是通过调用addActor（）来绘制LineWidget。然后将此actor添加到屏幕内的舞台。我不认为这些信息很重要，只是添加它以防万一。我测试了所有这些actor，当我绘制LineWidget Actor时，内存泄漏就开始了。
