A Tutorial on Garry’s Mod

How to use Garry’s Mod

Creating a Super Mortar Tank

(Necron41)

Okay, first go down to your tool bar, click on the steam icon, this will activate the pop-up window

Then, click on your newly installed Garry’s Mod and click Launch down near the bottom

Once the game is loaded, select your graphics settings to what you think your computer can

handle by going to Options, Video, Advanced then using the settings. After that click Play Single

player, then gm_flatgrass

Get familiar with the moving of your guy, scroll up and down to select different weapons and try

firing them. Once you are familiar hit ‘v’ . This will enable you to fly through objects and in the air, the direction you look is the direction you will

travel, wsad does not apply while flying.

Hit and hold down ‘q’ in order to bring up the spawn menu. Scroll up and down to look at the different things you can spawn. Do not worry,

there are many more. Looking at the top part you will see we are under Useful Construction Props, this is the most useful of all sections as you will

use it a lot. Clicking on different names will change it to different things, also notice the tabs

at the top.

Click on the Browse tab at the top, this will bring up many more things you can spawn, double-click

on Half Life 2 to open more selections.

Go to the pipes selection, then click the top right one 2 times to spawn it 2 times. You can move

around while spawning objects, which helps when spawning NPC’s and other large objects.

Okay, first right click on one of the pipes, this will lock it in place, when you lock it a small circle will appear then disappear, to unlock it left click on it

again or right click it again.

Left click the other pipe and move it so that is resting like this next to the other pipe. To bring a

object closer or farther away scroll up or down, how far away you are when you click it also effects the length, right click the pipe you just grabbed also.

Bring up the spawn menu again, on the right side under constraints click on weld, this is the most important tool. It lets you weld stuff, go figure.

To weld first click on one thing that is near another object, after clicking on the first, click on the other object near it as seen on the next slide. Weld like this all the way around the pipes that

you can see.

You do not have to weld this close but there are 3 rules to remember when welding.

1: the closer you weld, the more solidly combined the objects are

2: The more you weld it, the stronger it is, welding once will make it flail around.

3: make sure you do not weld something to the ground, if you think this has happened press ‘z’ to undo it.

Red lines indicate where to weld. (Continue on other side)

Now it should be a sturdy weld since you welded all around it. Since it is welded it acts like 1 object and it is grouped. Click on 1 pipe and left click it

again to release the lock, move it around and drop it a few times to make sure it is sturdy, if

not, weld it more.

Now press ‘v’ to use no clip flying (unless you are already doing it) Go inside the pipe and weld all around in there, you may have noticed there’s a

crack in the pipe welding, do not worry, if you can want you will learn how to fix that and you can go

back and redo it. But it will work fine.

Okay. Now it is a very strong weld, be proud of what you did.

Go back to the spawn menu, then go back to regular useful construction props, about ¾ down

you will see blast doors. Select a single blast door.

Open the spawn menu again and spawn this laundry basket, its very important. Also it holds

laundry..

Open the menu once again and under Useful Comic Props (this selection of things also rocks) And scroll down about mid way until you see a

pipe like the once selected, spawn it.

Take the pipes, lift them up and hold them in place with a right click. Then take the blast door and do as shown. Right click that too while your

at it.

Go to the spawn menu and select ball socket. Notice the torque and force limits, set them to ‘0’

which means they will never break

To create ball sockets it’s the same principle as welding, make two ball sockets as shown,

relatively close together. If you have just one it will swing around like crazy.

Release the blast door, it should swing around like this. Don’t worry its okay.

Go to the spawn menu and get winches, these are kind of like ropes that get shorter and longer at your command. Make increase and decrease

speed 100, rope width around 2 and the commands 0 and . When you start typing things while in the spawn menu (like typing 100) you no

longer need to hold down Q)

Winches work like ball sockets and welds, first click on the blast door.

Then click on the pipe like shown, do it again for the bottom. When positioning two or more winches

make sure if there using the same command there not too far apart, this will cause the shorter one to

keep getting shorter while the longer is still closing, causing unnecessary stress on the objects.

Spawn a fence, and grab that. It is under useful construction props.

Now were going to *gasp!* put the fence inside the pipe. To do this were going to make it not collide

with the pipe, select no collide under the construction tab.

First left click on the fence, then left click on this pipe (the once with the door hinge you make on it earlier). Make sure not to right click, this makes it

not collide with everything which is bad.

Now just take the fence, move it over the blast door and into the pipe like this, make sure not too much

is sticking out at the bottom. Also make it even.

See how its all nice and even. Good for you. Now take that laundry basket I told you to spawn earlier and no-collide that with the fence (left clicking) and the pipe (also left clicking) position it like this, so it is in the

pipe and the fence is right near it.

By now you should have something that looks like this. If it does, go get yourself something nice. If not,

you fail and re-do it.

Now go to the spawn menu, get dynamite and set it for ( . ), take no notice of the 8, also set the

explosivity level for 500) Spawn 4

Now take that dynamite and put 2 sticks of dynamite in the barrel, they will be stuck in place

until you click on them.

When its all said and done, it should look like this, intimidating isn’t it?

Now go to useful comic props and put whatever you want in the barrel, I recommend CRT monitors since

these seem to fly the farthest, car batteries also work. But feel free to use whatever you want.

Press . To ignite your dynamite and send the ammo flying as shown above. A key thing to remember, the

more things you have in the gun, the shorter the distance they will go since less energy is giving to

each item, if I had only 4 monitors they would have gone much farther, as oppose to them trickling out

with 30. Feel free to play with the cannon, since you made the effort to make it.

This is a picture of the explosion, notice how big it is with 4 dynamite sticks. Also notice the plumbing fixture you have not worked on yet. This picture

caused me damage.

Since the explosion was so big I decided to use the remover tool to get rid of 2 dynamite sticks, sadly I accidentally removed the pipe, so be careful using

this tool, notice how the dynamite is outlined in white, this means it is selected and I can remove it.

Remember that plumbing fixture I demanded you to spawn, now take it and weld it to the blast door, this will help you open it. (Note if you can already open it

fine you can skip this step)

Now would be a god time to check your FPS, hit ESC then options, under keyboard go to advanced and

enable consol

Go back to the game, then press ~ to open up to consol, type in Net_graph 1 to display your FPS and

other important junk.

Congrats, you have created the cannon for the super mortar tank, dork around with it, adjust the

height, use the door to open up the cannon and add dynamite, color it if you want and add pretty

balloons, also try firing watermelons, its tradition.
