Matrix4x4.SetTRS

Description

Sets this matrix to a translation, rotation and scaling matrix.

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

// Translate, rotate and scale a mesh. Try varying
// the parameters in the inspector while running
// to see the effect they have.
