当 Player 与 Wall 碰撞时，它会将他弹开并向前从一堵墙发射到另一堵墙，我不知道如何解决它

Question

这是我的代码 并链接到视频，在那里你可以看到我的“怪物” 文字 Player 和 Walls 有标签 - Player, Wall

对撞机

None physical Material
Is Trigger - unchecked
Radius - 0.5

和 Rididbody 与

Mass - 1
Drag - 0 
AngularDrag = 0.05
Use Gravity = unchecked
Is Kinematic = unchecked

我的目标是让玩家在下一步与他碰撞时不能向墙的方向移动（例如，如果玩家按下“A”，并且按下“A”，他将与墙碰撞，什么都不会发生，但如果下一步不撞墙等，他将能够以“W”向前移动。

当我启动游戏时，它就像视频中那样弹回虚空

Answer 1

还有第二个代码变体，我没有完全中断移动，但是我可以在按下 WASD 的同时向墙移动，如果我在墙上移动，玩家会绊倒它并弹开，然后移动中断。
