I have been playing a bunch of GMod lately. I have picked up quite a few building tips that you should know:
When using the physics gun on an object, holding down "shift" and hitting "E" snaps it to a grid for nice angles and alignment.
That add-on that I got that places a grid over props - it also provides snapping. Whenever you see that grid, you can hold down "E" to snap your tool to the grid.
I have made some pretty sweet stuff that I will share once I have it polished some more.
I made a jet that flies really stably. It has a cockpit for both a pilot and gunner. Pilot seat has a lot of flight instrumentation and the gunner has weapons instrumentation. Weapons include machine guns (4 total), and also bombs. I am going to add rockets and seeking missles as soon as I determine the best way to make really accurate missles.
Remaining stuff:
I also have a 3D scanner that uses a ranger to scan an object, store it in a RAM chip and output it via a holoemitter. Something is wrong with it and it doesn't work 100% yet.
Other ideas:
I made a pretty neat rollercoaster and a blimp! It is pretty neat that the blimp is actually propelled by propellers, rather than thrusters or anything like that.
I made 2 different aircraft carriers, not finished yet but looking pretty good. 1 is a catamaran (2 hulls) and is HUGE, the other is a single hulled one about half as big but still plenty big for aircraft to take off and land.
Working on a spaceship.
I made kind of a 'generic' manned turret (you sit in a cockpit and direct it). Using this as a base, I created a tractor beam turret for use with my spaceship. It can attract or repel objects, as well as lock onto them and hold them in place. Only problem is with dealing with distant/massive objects. Because they are pretty decent distance away, they have good leverage against me.
Also created a fully working radar for my aircraft carriers. I am working on making it more accurate, but it is pretty sweet already.
wow nice job dude. we should all play sometime and you can dup. all those items and we can fuck around.
I improved my radar. Also my spaceship is coming along nicely! It has a pilot seat that controls it at sublight speeds (thrusters). Another seat is for the navigator. He can choose between multiple jump points, and initiate a hyperdrive jump. Alternatively a directional jump of a configurable distance can be performed (ie jump 3000u in front of the ships current position). There is a hanger that can hold 4 fighters. They are held in place when not in use by grabber devices, this stops them from falling out of the hanger, and also means they jump with the ship when docked.
Todo -
The biggest downfall with the jumpdrive is that any players inside the ship must be within a 'vehicle' or they wont jump with the ship. Thus, before performing a jump, you need to take a seat.
I thought I posted these but I cant find them:

I have gotten my jet down to near-perfection. I rebuilt it from scratch. This time I used an Expression Chip with a bunch of code in it, rather than using ~20 different chips. It has 4 guns which are pretty perfectly aligned, and can drop bombs. I finally got decent landing gear to work ok. This version is a 1 seater, but its pretty trivial to add another seat if needed. I have an ejection seat I am working on, which needs tweaking. I am going to look into adjustable thrust (throttle up and down) as well as missiles. I have a missile addon however it has a problem in that when I advanced dup a contraption, it forgets the wiring to the missile, so I am thinking of alternate means.
Started work on a helicopter. This is really tough, but I am getting there.
Forgot to mention: proof that my jet works pretty good. Gerba and I played a bit today together and had some pretty sweet dogfights. It was kind of funny because Gerba was lagging and would crash, I would fly over and do a strafing run followed by a carpet bombing.
I am looking into these:
I have made some neat stuff lately. I have improved my targeting system. This is a general purpose targeting system that can be used for all sorts of stuff, I am using it with missiles right now. It takes in a x,y,z coordinate which can come from anywhere (I am using a laser pointer receiver) finds the nearest targetable object to that point and locks onto it, outputting it's x,y,z. It uses a whitelist to determine what can be targeted.
I also made a really accurate turret. It can shoot a manhack from across the map. It can also easily shoot down missiles, grenades, pretty much anything. It seems to be slightly off when shooting RPGs, but this can be easily rectified by making it slightly less accurate (more spread). It is fairly intelligent, it detects when a target dies and moves to the next immediately. It also is virtually impossible for it to hit an incorrect target (ie if you run into its line of fire) since it detects what it is currently aimed at and checks to see if that is its target. If it is unable to kill a target within 2 seconds, it moves onto the next. These two features combined means that if a target is hidden from view, it will detect that it cannot shoot it, wait up to 2 seconds trying, and move on to the next rather than becoming "stuck" on a target. I also made a rocket version that is pretty sweet. You could easily mount any kind of weapon on it. I also made a plasma gun and grenade launcher.
Right now, it uses an external target finder to find its targets. I am working to incorporate the targeting into the main chip right now. I also want to reduce wobble when it is attached to a moving object. I welded it to a car and drove around and it was easily able to kill targets, but it had a little trouble when attached to a jet since it is going fast and moving a lot.
Also, I found out that the top speed in Garry's Mod is 113MPH or ~2000units/s (inch/s). I also found a addon on that allows you to break this speed barrier and go pretty much as fast as you want until the game crashes.
