java - 边界球碰撞不起作用

Question

我尝试在我的 LWJGL 游戏中实现模型之间的碰撞，即使碰撞半径仅为 0，对象似乎仍在不断碰撞。我已将碰撞的代码放在下面，以及指向的链接我用来帮助边界球体碰撞的来源。

package model;

import org.lwjgl.util.vector.Vector3f;

public class BoundingSphere {

    private Vector3f mid = new Vector3f();
    private float radius;

    public BoundingSphere(Vector3f midpoint, float radius) {
         this.mid = midpoint;
         this.radius = radius;
    }

    public boolean isColliding(BoundingSphere other){
        float diffX = (other.mid.x - mid.x);
        float diffY = (other.mid.y - mid.y);
        float diffZ = (other.mid.z - mid.z);

        float diffXSquared = (float) Math.pow(diffX, 2);
        float diffYSquared = (float) Math.pow(diffY, 2);
        float diffZSquared = (float) Math.pow(diffZ, 2);

        float radiusSums = (other.radius + radius);
        float radiusSumsSquared = (float)Math.pow(radiusSums, 2);

        if (diffXSquared + diffYSquared + diffZSquared > radiusSumsSquared){
            return true;
        }
        else{
            return false;
        }

    }

}

Answer 1

看来您已经颠倒了条件。仅当出现以下情况时才会发生碰撞:

((x2 + y2 + z2) <= r2)

如果你想要重叠而不是碰撞，那么“<=”将是“<”
