translate
Applies an additional translation to this transform's current position and returns a new Transform with the combined position.
The new position is calculated by performing an element-wise addition of this transform's current position vector (this.position) with the input translation vector.
The orientation (quaternion) and scale components of the transform remain unchanged. This operation assumes that the + operator for Vector3 performs element-wise addition.
Return
A new Transform instance with the updated position, while retaining the original orientation and scale.
Parameters
translation
A Vector3 representing the translation to apply to the current position.
