Unity3d:将游戏对象旋转到另一个游戏对象的正向向量
Unity3d:将游戏对象旋转到另一个游戏对象的正向向量
提问于 2019-07-10 03:49:32
BackCube.position = cameraEye.position - cameraEye.forward * 2;
float back = cameraEye.position.z - 2f;
BackCube.position = new Vector3(BackCube.position.x, BackCube.position.y, back);
var lookPosBack = cameraEye.position - BackCube.position;
lookPosBack.y = 0;
var rotationBack = Quaternion.LookRotation(lookPosBack);
BackCube.rotation = Quaternion.Slerp(BackCube.rotation, rotationBack, 1);所以，我想让my BackCube向cameraEye的正向矢量旋转。上面的代码查看的是cameraEye，而不是cameraEye的正向向量。我希望两者的正向向量彼此指向，彼此之间相距2个单位。我只能控制BackCube

这起作用了！
Vector3 direction = Vector3.ProjectOnPlane(cameraEye.forward, Vector3.up);
BackCube.transform.position = cameraEye.position - direction.normalized * 2;
var lookPosBack = cameraEye.position - BackCube.position;
lookPosBack.y = 0;
var rotationBack = Quaternion.LookRotation(lookPosBack);
BackCube.rotation = Quaternion.Slerp(BackCube.rotation, rotationBack, 1);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
