检测凸多边形碰撞的一种简单的方法是SAT(Separating Axis Theorem),即分离轴定理. 原理:将多边形投影到一条向量上,看这两个多边形的投影是否重叠.如果不重叠,则认为这两个多边形是分离的,否则找下一条向量来继续投影.我们不需要比较很多条向量,因为已经在数学上证明,多边形每条边的垂直向量就是我们需要的向量. 1.AABB 让我们首先以AABB开始(AABB是一种两边分别平行于X-Y轴的矩形) 判断两个AABB是否碰撞,我们只需要投影两次,分别是投影在平行于X轴和Y轴的向量上…
Given a 2D grid, each cell is either a wall 'W', an enemy 'E' or empty '0' (the number zero), return the maximum enemies you can kill using one bomb. The bomb kills all the enemies in the same row and column from the planted point until it hits the w…
