c++ - 水平碰撞不起作用 AABB C++

Question

更新

再次更改了碰撞代码并为AABB制作了一个组件，现在看来问题仅在于水平碰撞，它没有将物体推到它认为足够的位置但是与Y轴的代码相同所以它不应该成为一个问题。

(它确实检测到水平碰撞分辨率是问题)

void Hermes_Player::Collision(GameObject * other)
{
    if (other->GetTag() == "wall") {
        AABB* myAABB = dynamic_cast<AABB*>(this->GetComponent("aabb"));
        AABB* otherAABB = dynamic_cast<AABB*>(other->GetComponent("aabb"));
        if (abs(myAABB->lastCenter.x - otherAABB->lastCenter.x) < myAABB->halfCenter.x + otherAABB->halfCenter.x) {
            std::cout << "y" << std::endl;
            if (myAABB->center.y < otherAABB->center.y) {
                int distance = (myAABB->halfCenter.y + otherAABB->halfCenter.y) - (otherAABB->center.y - myAABB->center.y);
                this->Position.y -= distance;
                myAABB->center.y = (myAABB->center.y - distance);
            }
            if (myAABB->center.y > otherAABB->center.y) {
                int distance = (myAABB->halfCenter.y + otherAABB->halfCenter.y) - (myAABB->center.y - otherAABB->center.y);
                this->Position.y += distance;
                myAABB->center.y = (myAABB->center.y + distance);
            }
        }
        else
        {
            std::cout << "x" << std::endl;

            int dist = myAABB->halfCenter.x + otherAABB->halfCenter.x;
            int dif = (this->Size.x + other->Size.x) /2- abs(dist);
            if (myAABB->center.x < otherAABB->center.x) {
                int distance = (myAABB->halfCenter.x + otherAABB->halfCenter.x) - (otherAABB->center.x - myAABB->center.x);
                this->Position.x -= distance;
                myAABB->center.x = (myAABB->center.x - distance);
            }
            if (myAABB->center.x > otherAABB->center.x) {
                int distance = (myAABB->halfCenter.x + otherAABB->halfCenter.x) - (myAABB->center.x - otherAABB->center.x);
                this->Position.x += distance;
                myAABB->center.x = (myAABB->center.x + distance);
            }
            std::cout << this->Position.x << std::endl;
        }
    }
}

这可能不是您想要的，但尝试同时解析 X 轴和 Y 轴可能会相当复杂。

一个解决方案可能是独立步进每个轴并分别解决它们的碰撞。

您必须执行两次碰撞检测，但它使解决更简单，IE 不会检查碰撞解决是否导致更多碰撞，您只需停止沿着第一个碰撞对象的边缘移动。
