unity物体运动经过特定点并绘出轨迹

这篇具有很好参考价值的文章主要介绍了unity物体运动经过特定点并绘出轨迹。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

经过线如果有圆滑可以参考

Unity物体运动时画出轨迹_天人合一peng的博客-CSDN博客

并修改里面的数值轨迹会有变化

float angle = Mathf.Min(1, Vector3.Distance(this.transform.position, targetPos) / distanceToTarget) * 45;
this.transform.rotation = this.transform.rotation * Quaternion.Euler(Mathf.Clamp(-angle, -42, 42), 0, 0);

经过特定点时螺钉出现并有动画
