SetTRS(Vector3, Quaternion, Vector3)

Sets this matrix to a translation, rotation and scaling matrix.
public void SetTRS(Vector3 pos, Quaternion q, Vector3 s)

Parameters

pos

Vector3

q

Quaternion

s

Vector3

Remarks

The current matrix is modified so that it places objects at position 
pos
, oriented in rotation 
q
and scaled by 
s
.

Try varying// the parameters in the inspector while running// to see the effect they have.using UnityEngine;using System.Collections;public class ExampleClass : MonoBehaviour {    public Vector3 translation;    public Vector3 eulerAngles;    public Vector3 scale = new Vector3(1, 1, 1);    private MeshFilter mf;    private Vector3[] origVerts;    private Vector3[] newVerts;    void Start() {        mf = GetComponent<MeshFilter>();        origVerts = mf.mesh.vertices;        newVerts = new Vector3[origVerts.Length];    }    void Update() {        Quaternion rotation = Quaternion.Euler(eulerAngles.x, eulerAngles.y, eulerAngles.z);        Matrix4x4 m = Matrix4x4.identity;        m.SetTRS(translation, rotation, scale);        int i = 0;        while (i < origVerts.Length) {            newVerts[i] = m.MultiplyPoint3x4(origVerts[i]);            i++;        }        mf.mesh.vertices = newVerts;    }}
