You could probably make it the same way you create a bullet. just make the spr image really long like 1000 pixel width or however long your game screen is. Then just set the speed = 0. You would have to create an end step as well so that it keeps redrawing.
You would have to remove any instance destroy command for when it hits walls or goes outside the room. Make a several frame spr to animate it with glow and such. Then you could write the damage code based on the room speed or something.
There is some code you could program the length of the beam if you wanted to.
Edit: I think distance_to_point is what you would need.
Otherwise just do some instance destroy collision events with certain object in the room for the player to hide behind and such.

As for it's movement, there's plenty of ai tutorials out there on how you could program a turret of sorts to just rotate clockwise or randomly however you want.
