how to make units unable to move but still able to rotate

[Wietlol]

I thought that there was a trigger action (or jass function) that could do this but I cant recall what it was.

Anyone knows what it is?

There is SetUnitMoveSpeed but I'm not sure if it can rotate. SetUnitPropWindow can do it for sure (setting it to 0). E: Just in case, you cant set it to 0 in GUI - the BJ defaults it to 1.

E: The Root ability works for buildings.

Setting their movement to float works, but only if you spawn them in and if they're not too close to water.

//  DisableUnitMovement /* v1.0.0.1
//    *   Disables unit movement. They can still turn, but will stay in
//    *   place. It simulates an ensnare-like effect, except that it will
//    *   not ground units, it does not have buffs, does not interrupt
//    *   channeled casts and appears to have no downsides.
//    *   Full credits to WaterKnight for discovering this technique.

function DisableUnitMovement takes unit u returns nothing
    call SetUnitPropWindow(u, 0)
endfunction
//--------------------------------------------------------------------     
function EnableUnitMovement takes unit u returns nothing
    call SetUnitPropWindow(u, GetUnitDefaultPropWindow(u) * bj_DEGTORAD)
endfunction

SetUnitPropWindow was what I was looking for.
Thanks!
