LibGDX：最大屏幕宽度

Question

I'm trying to limit the end of the screen so that the sprite (base) when it reaches the end of the screen does not exceed.

@Override
public void create () {
    rectangleBase = new Rectangle();
    endScreen = new Rectangle();
    startScreen = new Rectangle();
    base = new Texture("base1.png");
    deviceHeight = Gdx.graphics.getHeight();
    deviceWidth = Gdx.graphics.getWidth();
    posYBase = (deviceHeight * 20) / 100;
 }

@Override
public void render () {
    moveBase();
    collisionScreenBase();
    spriteBatch.begin();
    drawBase();
    spriteBatch.end();

}
// Here it is used to move the base in pos X with the touch
// I need to make the collision in that method or create another?
void moveBase(){
    posXBase = Gdx.input.getX();
    if(Intersector.overlaps(rectangleBase, endScreen)){
       // Do something
    }
}

void drawBase(){
    spriteBatch.draw(base, posXBase, posYBase);
}


void createCollision(){
    rectangleBase.set(posXBase, posYBase, base.getWidth(),base.getHeight());
    endScreen.set(deviceWidth - 1, 0, 1, deviceHeight);
    startScreen.set(1 + 1, 0, 1, deviceHeight);
}

How can I limit the posX of the base so it does not exceed the end of the screen?

Answer 1

Insert this in your moveBase() method instead of the if(Intersector...) statement:

//If the base exceed on the right side
if(Gdx.graphics.getWidth() < posXBase + rectangleBase.getWidth()){
    //set the posXBase as far right as possible without exceed
    posXBase = Gdx.graphics.getWidth() - rectangleBase.getWidth();
//If the base exceed on the left side
else if(posXBase < 0)
    //Set the posXBase to 0
    posXBase = 0;
