Unity中location和rotation赋值和更改-Toy模板网

这篇具有很好参考价值的文章主要介绍了Unity中location和rotation赋值和更改。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。

Unity中location可以和Vector3向量相加减和通过new Vector3更改位置。如：

public Vector3 cubeposition = new Vector3(0,0,0);

cubeposition = new Vector3(Xadjustposition, Yadjustposition, Zadjustposition);
GameObject.Find("newcube").transform.position = cubeposition;

但rotation不行，要用Quaternion.Euler赋值的办法才能赋值或更改角度。如：

public Quaternion cuberotation = Quaternion.identity;//四元素初始化只能这样

cuberotation = Quaternion.Euler(Xadjustrotation, Yadjustrotation, Zadjustrotation);

GameObject.Find("newcube").transform.localRotation=cuberotation;

或者GameObject.Find("newcube").transform.localRotation=Quaternion.Euler(Xadjustrotation, Yadjustrotation, Zadjustrotation);

综合：

GameObject.Find("newcube").transform.localPosition = cuberotation * new Vector3(translation.y, translation.z, -translation.x) + cubeposition;

下面是更完整一点儿的摘抄：

float Xadjustposition, Yadjustposition, Zadjustposition, Xadjustrotation, Yadjustrotation, Zadjustrotation;
public Vector3 cubeposition = new Vector3(0,0,0);
public Quaternion cuberotation = Quaternion.identity;//四元素初始化只能这样

Matrix4x4 matrix = new Matrix4x4();
matrix.SetRow(0, new Vector4(m[3], m[6], m[9], m[12] / scaleMultiplier));//经过实际测试前三个都是0，从第四个开始才跟transform中的数据一样，跟openIGTLink官方的协议说明不同，按实际的来，所以从m[3]开始
matrix.SetRow(1, new Vector4(m[4], m[7], m[10], m[13] / scaleMultiplier));
matrix.SetRow(2, new Vector4(m[5], m[8], m[11], m[14] / scaleMultiplier));
matrix.SetRow(3, new Vector4(0.0f, 0.0f, 0.0f, 1.0f));

Vector3 eulerAngles = matrix.rotation.eulerAngles;
GameObject.Find("newcube").transform.localRotation = Quaternion.Euler(eulerAngles.x, -eulerAngles.y, -eulerAngles.z);

Vector3 markerposition = GameObject.Find("ImageTarget2").transform.position;//ImageTarget2
Quaternion markerrotation = GameObject.Find("ImageTarget2").transform.rotation;

cubeposition = markerposition + markerrotation * new Vector3(0, -0.03f, -0.114f);

cubeposition = markerposition + markerrotation * (cubeposition - markerposition);//此句虽然是用的向量加旋转，但依然是眼镜获得的两个全局值再运算，跟上面一个效果，多一层误差。

public void XpositionPlus()
{

float result = 0;
string textValue = XpositionInput.GetComponent<InputField>().text;
result = float.Parse(textValue);
Xadjustposition = Xadjustposition + result / 1000;
cubeposition = new Vector3(Xadjustposition, Yadjustposition, Zadjustposition);
GameObject.Find("newcube").transform.position = cubeposition;
}

//以下是rotation
public void XrotationPlus()
{

float result = 0;
string textValue = XrotationInput.GetComponent<InputField>().text;
result = float.Parse(textValue);
Xadjustrotation = Xadjustrotation + result;
cuberotation = Quaternion.Euler(Xadjustrotation, Yadjustrotation, Zadjustrotation);

GameObject.Find("newcube").transform.localRotation=cuberotation;
