快速移动目标的瞄准算法和程序实现

Realization of Algorithm and Program to Aim at the Quickly-moving Object

在塔防游戏中,对于飞机等快速移动且距离较远的目标,火炮直接向目标射击是不可能命中的。本文在分析炮弹和飞机的运动情况的基础上,提出逐次迭代逼近的方法求解命中点,并将世界坐标系转换到火炮坐标系以简化求解过程,使火炮能够快速指向命中点,最后文章给出了主要的程序实现步骤。

In tower defense game,it＇s impossible for the artillery to hit directly the objects which are moving quickly and in faraway distance such as aircraft.Based on the analysis of artillery and aircraft movement,the article put forward the method of successive iteration approximation to get the impact point, as well as the transformation from the world coordinate system to artillery coordinate system to simplify the solution process.Using this method,the artillery can quickly point to the impact point.This article also gives the implementation steps of main programs.
