Rotate circle on mouse position

[Luka]

Got an idea to make a battleship with working guns and stuff. The only problem is that I can't understand completely what's going on in the automated mouse-controlled gun (the one made by pixartist). And I just want to activate the axle without changing the RPM.

Help will be helpful

EDIT - This is the thing which I want.

Simplest way is to set bend / bendTarget for turrel and connect it to +inf inertiaMultilpier circle.

Draw new circle on top of turret, hinge it to turret.

in circle ->
postStep = (e) => {scene.my.tpos = pos}
onSpawn = (e) => {scene.my.tpos = pos}
inertiaMultilpier = +inf

in bend hinge ->
bend = true;
bendTraget = {v := app.mousepos - scene.my.tpos; math.atan2(v(0),v(1))}

Worked. By the way the bendTarget was offset.
So I changed the atan2 part code and swapped 0 with 1 and 1 with 0 (that's how math calculates angle from 2 variables).
