c++ - 矩形碰撞检测

Question

class Rectangle{
public:
   float x, y, width, height;
   // (x,y) is the lower left corner of the rectangle
};

这个算法正确吗？

bool Rectangle::colidesWith(Rectangle other) {
   if (x+width < other.x) return false; // "other" is on the far right
   if (other.x+other.width < x) return false; //"other" is on the far left
   if (y+height < other.y) return false // "other" is up
   if (other.y+other.height < y) return false // "other" is down
   return true;
}

Answer 1

如果矩形被填充(即，如果其中一个在另一个矩形内，则算作碰撞)。
