Collision detection between two BoundingBoxes in libgdx

In my libgdx game I have 3D BoundingBoxes for map and player objects. I want to find out whether they collide in 3D space. How can I do this?

Solution

  • You can use the following method:

        public static boolean intersectsWith(BoundingBox boundingBox1, BoundingBox boundingBox2) {
        Vector3 otherMin = boundingBox1.getMin();
        Vector3 otherMax = boundingBox1.getMax();
        Vector3 min = boundingBox2.getMin();
        Vector3 max = boundingBox2.getMax();

        return (min.x < otherMax.x) && (max.x > otherMin.x)
            && (min.y < otherMax.y) && (max.y > otherMin.y)
            && (min.z < otherMax.z) && (max.z > otherMin.z);
    }

    It's modeled after this method: https://github.com/MasDennis/Rajawali/blob/master/src/rajawali/bounds/BoundingBox.java#L186
