开发笔记:如何在我的播放状态课程中更新我的游戏分数

我正在开发小动画游戏，当我触摸物体时，它会杀死一些物体。

当我杀死他们时我得分，但我不知道在我的游戏班上显示我的最新分数。

这是我的班级：

public class PlayState extends State implements Input.TextInputListener {
private static int FREQUENCY=100;
boolean alive;
Texture mBackground,mScore;
List bugs;
int x,type,count,score;
int xScale,yScale;
public PlayState(StateManager manager) {
super(manager);
mBackground=new Texture("bg_game1.jpg");
mScore=new Texture("score.jpg");
bugs=new ArrayList();
alive=true;
count=FREQUENCY;
score=0;
xScale=AntSmasher.WIDTH/AntSmasher.VIRTUALWIDTH;
yScale=AntSmasher.HEIGHT/AntSmasher.VIRTUALHEIGHT;
}
@Override
public void handleInput() {
if(Gdx.input.justTouched()){
if(alive) {
for (Bug ref:bugs) {
if(ref.getLife()){
TextureRegion image = ref.getRegion();
int
xTouch = Gdx.input.getX(),
yTouch = Gdx.input.getY();
int
xMin = (int) ref.getPosition().x,
xMax = xMin + image.getRegionWidth()*xScale,
yMin = AntSmasher.HEIGHT - ((int) ref.getPosition().y) - image.getRegionHeight()*yScale,
yMax = yMin + image.getRegionHeight()*yScale;
if (xTouch <= xMax && xTouch >= xMin &&
yTouch <= yMax && yTouch >= yMin) {
FREQUENCY*=1.0;
AntSmasher.YSPEED*=1;
ref.die();
if(ref instanceof BlackAnt)
score++;
else if(ref instanceof BrownAnt)
score+=2;
else
score+=3;
}
}
}
}
}
}
@Override
public void dispose() {
mBackground.dispose();
mScore.dispose();
for (Bug ref2:bugs)
ref2.dispose();
}
@Override
public void update(float dt) {
handleInput();
if(alive) {
if (count++ >= FREQUENCY) {
x = (int) (Math.random() * (AntSmasher.WIDTH-100*xScale) + 1);
type = (int) (Math.random() * 3);
if (type == 0) {
BlackAnt bug = new BlackAnt(x);
bugs.add(bug);
} else if (type == 1) {
BrownAnt bug = new BrownAnt(x);
bugs.add(bug);
} else {
Scorpion bug = new Scorpion(x);
bugs.add(bug);
}
count = 0;
}
for (Bug ref : bugs){
ref.update(dt);
if(ref.getPosition().y<=0) {
alive = false;
Gdx.input.getTextInput(this, "Game Over", "", "Score is : "+String.valueOf(score));
AntSmasher.YSPEED=-400;
FREQUENCY=100;
manager.set(new MenuState(manager));
break;
}
}
}
}
@Override
public void render(SpriteBatch sb) {
sb.begin();
sb.draw(mBackground,0,0,AntSmasher.WIDTH,AntSmasher.HEIGHT);
BitmapFont fOnt= new BitmapFont();
font.draw(sb,"Score :"+ String.valueOf(score), 500, Align.topLeft);
font.setColor(Color.WHITE);
float ratio=(float)AntSmasher.WIDTH/(float)mScore.getWidth();
sb.draw(mScore,
(AntSmasher.WIDTH-mScore.getWidth()*ratio)/2,
AntSmasher.HEIGHT-mScore.getHeight()*ratio-50*AntSmasher.HEIGHT/AntSmasher.VIRTUALHEIGHT,
mScore.getWidth()*ratio,
mScore.getHeight()*ratio);
for(Bug ref:bugs) {
if(ref.getLife())
sb.draw(ref.getRegion(),
ref.getPosition().x,
ref.getPosition().y,
ref.getRegion().getRegionWidth()*xScale,
ref.getRegion().getRegionHeight()*yScale);
else
sb.draw(ref.getImage(),
ref.getPosition().x,
ref.getPosition().y,
ref.getImage().getWidth()*xScale,
ref.getImage().getHeight()*yScale);
}
sb.end();
}
@Override
public void input(String text) {
AntSmasher.firebase.addToFirebase(text,score);
//AntSmasher.firebase.addToFirebase("Okay",score);
score=0;
}
@Override
public void canceled() {
AntSmasher.firebase.addToFirebase("Anónimo",score);
score=0;
}
}


请帮助我，因为我错过了在PlayStation屏幕上更新分数的代码。
