问题描述
最近我进入Unity并遇到了一个奇怪的错误，那就是在我运行的第一个场景中进行第一次重载（重生）后，角色的跳跃高度才更高。
方案1：
- 正在加载场景1。角色正在以正确的高度跳动。
- 角色死亡。场景1重新加载，角色重新生成。现在角色跳得比预期的要高得多。
- 清除场景1，移至场景2。角色现在可以正常工作（即使在重生之后也可以）。
方案2：
- 正在加载场景2。场景1中的确切问题发生在场景2中（因为这是我运行的第一个场景）
- 清除场景2，移到场景3。角色现在可以正常工作（即使在重生之后也可以）。
我已经研究了几个小时，但我仍然不知道错误在哪里。

请让我知道是否需要更多信息。
解决方法
将跳跃力乘以Time.DeltaTime。
Time.DeltaTime是表示自上一帧以来的完成时间（以秒为单位），因此与之乘以或jumpForce可以确保无论在不同设备上获得的帧速率如何，或何时获得帧，我们都跳相同的高度率下降。
请注意，您还在Move函数内的CharacterController类中施加了力量：m_Rigidbody2D.AddForce(new Vector2(0f,m_JumpForce));
