C# 如何在Unity 3d中跳过固定距离？
我有一个控制器，可以沿对角线移动我的对象。左箭头应将玩家向前向左移动45度，右箭头向右移动45度。我想将玩家移动到相对其当前位置。现在它相对于点（0,0,0）移动 我的代码：C# 如何在Unity 3d中跳过固定距离？,c#,unity3d,C#,Unity3d,我有一个控制器，可以沿对角线移动我的对象。左箭头应将玩家向前向左移动45度，右箭头向右移动45度。我想将玩家移动到相对其当前位置。现在它相对于点（0,0,0）移动 我的代码： public class JollyJumper : MonoBehaviour { protected CharacterController control; public float fTime = 1.5f; // Hop time public float fRange = 5.0f;

如何解决这个问题？有什么想法吗？非常感谢 简单的回答是：您硬编码了两个要跳转到的位置：点（1,1）和（-1,1）。您应该在每次开始跳跃时创建新向量。更换每个
direction = new Vector2(1.0f, 1.0f);
v3Dest = transform.position + new Vector3(1.0f, 0, 1) * fRange;
- 每次跳转后都会出现大量浮点错误。请注意，在您的代码中，
永远不会等于v3T
（您永远不会真正到达目的地），因为您之前切换了v3Dest
标志。跳转结束时，应明确将位置设置为移动v3Dest - 您正在检查跳转计时器等每一帧。一个更明智的解决办法是
- 使用正弦曲线作为跳跃曲线，看起来不错，但使用抛物线在概念上更为正确
- 现在可以开始下一次空中跳跃（我不确定是否有意）

}您能给我一些代码片段吗？我在编程方面有经验，但在Unity3d方面没有经验。只需在Unity inspector中将控制器拖放到播放器即可。或者设置
controller.transform.parent=player.transformcontroller.transform.parent=player.transform
