Unity API Parsing (8)--quaternion class

Four--consists of 4 components of x, Y, Z and W, which belong to the struct type

The selection angle used to store and represent objects

Eulerangles Properties--Euler's Corner

The transform of the Gameobject object is the order of the Euler angle, which rotates the corresponding angle around the z-axis, rotates the corresponding angle around the x-axis, and the last y-axis-the final state of the different rotation order.

Using unityengine;using System.collections;public class eulerangle_ts:monobehaviour{public    Transform A, B;    Quaternion rotations=quaternion.identity;    Vector3 eulerangle = Vector3.zero;    float speed = 10.0f;    void Update ()    {        ///The first method assigns quaternion to transform rotation        rotations.eulerangles = new Vector3 (0.0f, Speed * time.time, 0.0f);        A.rotation = rotations;        The second way, the three-dimensional vector represents the Euler angle directly assigned to the transform eulerangles        eulerangle = new Vector3 (0.0f, Speed * time.time, 0.0f);        B.eulerangles = Eulerangle;    }}

setfromtorotation--Creating an Rotation instance

Used to create a rotation from fromdirection to Todirection

cannot be set directly using the Transform.rotation.setFromToRotation (V1,v2) method, only the instantiated quaternion are assigned to Transform.rotation

Using unityengine;using System.collections;public class Setfromtorotation_ts:monobehaviour {public    Transform A, B , C;    quaternion q1 = quaternion.identity;void Update () {        //cannot be used directly c.rotation.setfromtorotation (a.position,b.position) ;        Q1. Setfromtorotation (a.position,b.position);        c.rotation = Q1;        Debug.drawline (vector3.zero,a.position,color.red);        Debug.drawline (Vector3.zero, b.position, color.green);        Debug.drawline (C.position, C.position+new Vector3 (0.0f,1.0f,0.0f), color.black);        Debug.drawline (C.position, C.transformpoint (vector3.up*1.5f), Color.yellow);}}

setlookrotation--Setting the orientation of the quaternion instance

quaternion q1 = quaternion.identity;

Q1. Setlookrotation (V1,V2);

Transform.rotation = Q1;

The Transform.forward direction is the same as the V1 direction

Transform.right perpendicular to Vector3.zero, V1 and V2, the 3-point plane

Can not be used directly using Transform.rotation.SetLookRotation (V1,V2), you should instantiate a quaternion and then use Setlookrotation The last assignment to Transform.rotation

The angular axis representation of a toangleaxis--quaternion instance

This method is usually used in conjunction with the static method Angleaxis (Angle:float, Axis:vector3), so that the rotation of an object remains consistent with the rotation of another object

Angle between angle--quaternion instances

Used to return the angle from parameter A to parameter B transformation--The angle returned is not the angle of a local axis to the transformation, but rather the Gameobject object from state A to State B to make the minimum angle required to be rotated

dot--Point Multiply

euler--four-dollar number of Euler angles

Returns a four-tuple instance of the Euler angle Vector3

Fromtorotation--quaternion Transform

inverse--Value of Reverse quaternion

lerp--linear interpolation

lookrotation--Setting the orientation of the quaternion

slerp--spherical interpolation
