How to scale an object and at same time fix the position ?

[tahatlal]

I’m trying to make a signal that expand like normal signal and move forward with the speed of sound …
this is for research helping my prof. to simulate this thing …
i tried to use local scale but always changing the position of my object over time …

 gameObject.transform.localScale +=new Vector3(0.3f,0.3f,0.3f);

 gameObject.transform.position += new Vector3(_x, _y, _z);

please help

my prefap: sigfi--.prefab - Google Drive

Parent it to an empty object in such way that the parent is located at the point from which the object should expand, and scale the parent.
