I need to know how to make a unit never move from a position but still be able to shoot or attk. How is this done?

Center locs a + b on the unit, A is 2x2, b is 5x5, when player brings 0 units to a, move unit at b to a

srry but I just found a way. I just created a location that was over water and had the unit move there it immobilizes it thanks though

You can also constantly move it off the map, which will work for air units. If you encounter problems with it not being attackable/attacking, you can use an inverted location to make it stand still by detecting when it's not in that location (which should be as soon as it moves 1 pixel in any direction).

Oh i didnt know they could still attack with that trigger

They can, although they have trouble locking on to a target, and other units attacking them often miss, and also have difficulty targeting them.
