我是libgdx新手,在向数组中添加矩形(“2”)时遇到了问题。添加并获取后,我无法检测碰撞。
我的代码如下:
...
public class MyGdxGame implements ApplicationListener
{
Texture texture;
SpriteBatch batch;
Rectangle one, two;
float x1=0,x2;
float y1, y2;
Array <Rectangle> array;
在Create()中:
texture = new Texture(Gdx.files.internal("android.jpg"));
batch = new SpriteBatch();
x2 = Gdx.graphics.getWidth()-40;
y1 = y2 = (Gdx.graphics.getHeight()/2)-15;
one = new Rectangle();
two = new Rectangle();
one.set(x1, y1, 40, 30);
two.set(x2, y2, 40, 30);
array = new Array <Rectangle>();
array.add(two);
在渲染器()中:
...
batch.begin();
batch.draw(texture, x1, y1, 40, 30);
batch.draw(texture, x2, y2, 40, 30);
try
{
Thread.sleep(10);
x1 += 2;
x2 -= 2;
one.set(x1, y1, 40, 30);
two.set(x2, y2, 40, 30);
这就是问题所在,因为“一”矩形无法检测到与“两”矩形的碰撞:
if(one.overlaps(array.get(1)))
{
x1 = 0;
x2 = Gdx.graphics.getWidth()-40;
}
}
catch(Exception e){}
batch.end();
谁能帮帮我吗?
