问题描述
我试图限制屏幕的末端，以使到达屏幕末端的子画面（底部）不超过。
@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);
}
如何限制基座的posX，使其不超出屏幕末端？

将此插入到您的moveBase()方法中，而不是if(Intersector...)语句中：
//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;
