# [Math]Projectile Motion: Finding the Optimal Launch Angle

If we want to throw a projectile as far as possible, at what angle should it be launched? This paper focuses on how the answer to this question changes depending on the situation. 如果你想尽可能远的抛掷物体，以多大的角度抛出最合适？这篇文章用于分析不同测试环境下而导致的不同答案。 论文地址：Projectile Motion: Finding the Optimal Launch Angle https://www.whitman.edu/Documents/Academics/Mathematics/2016/Henelsmith.pdf UE4实现：如何绕开障碍物并投掷到指定位置 Projectile: How to avoid obstacle & hit target https://www.reddit.com/r/unrealengine/comments/9xfdei/projectile_how_to_avoid_obstacle_hit_target/ 所有的战争都是内战，因为所有的人类都是同胞。——弗朗索瓦·费奈隆（FrancoisFenelon）
