问题描述
Libgdx中是否有办法验证Polygon和Circle之间的碰撞?
Is there a way in Libgdx to verify a collision between a Polygon and a Circle?
我看到 Intersector class但只找到Circle和Rectangle的碰撞测试。那么任何其他Polygon怎么样?
I saw the Intersector class but only found collision test for Circle and Rectangle. What about any other Polygon?
如果我需要手动完成,使用Libgdx最好的方法是什么?
If I need to do it manually, what's the best way to do that using Libgdx?
推荐答案因此,我设法在Circle和Polygon之间创建了一个碰撞测试方法。至少,它对我有用。
So, I managed to create a collision test method between a Circle and a Polygon. At least, it works for me.
这是代码:
public boolean overlaps(Polygon polygon, Circle circle) { float []vertices=polygon.getTransformedVertices(); Vector2 center=new Vector2(circle.x, circle.y); float squareRadius=circle.radius*circle.radius; for (int i=0;i<vertices.length;i+=2){ if (i==0){ if (Intersector.intersectSegmentCircle(new Vector2(vertices[vertices.length-2], vertices[vertices.length-1]), new Vector2(vertices[i], vertices[i+1]), center, squareRadius)) return true; } else { if (Intersector.intersectSegmentCircle(new Vector2(vertices[i-2], vertices[i-1]), new Vector2(vertices[i], vertices[i+1]), center, squareRadius)) return true; } } return false; }更多推荐
