Making your first room with Hammer SDK

Hammer is set up for Counter-Strike Source when you load it up, so we are not going to do anything about that, just how to make your first room. (Excuse if the images are hard to read, stupid paint… just make an effort)

So go to File->New and you will get this:

I have lined out some basic explanation to some of the tools, but here is what we are going to use the most.

A brush can be a block, cylinder, and lots of others. This is what we build out maps from.

Entity tool places things like Light and Player start positions can not play it without these.

Face edit is a very useful tool, say u have a wall separating a room into two, you can have a different texture on each side.

Ok, so lets make the bloody room.

Drag some brushes like this, this gives you a roof-less and bottomless "room"

[4]

Drag a couple of extra brushes to form a roof and floor, and select a different texture before you do this, by clicking the browse button in "Texture group"

[5] (I did not hit enter on the last brush so you can see how its placed)

Ok so we need a start position (two really) So select the Entity tool and place a info_player_terrorist and a info_player_counterterrorist, make sure they are above the floor or they will be excluded when you run the map. (so make the grid a bit smaller, two clicks)

[6]

Now you can actually play it, but its no fun (hit compile / F9) and make sure you copy the compiled bsp to your counter-strike source\maps folder (the bsp is most likely in \sourcesdk\cstrike_sample_content\maps) if you do this the map will be full-bright because we didn’t add a light to make shadows, yes that is how it works.

So use the entity tool and place a "light" entity at the top of the box.

[7]

Let’s make another room right besides this and link em up with a corridor. Select all the things you want to copy by holding CTRL and using the select tool and click on the brush in 3D view (you can move in it by tapping space and holding the mouse button and move around with WASD) Then click Ctrl+C and Ctrl+V (copy paste) and move the new room in position next to the first one like this:

[8]

Now, to link them together we need a corridor, simple, use the clip tool (read my clip tool tut [I believe he is referring to the tutorial on his website -- click Tutorials, and view the clipping tutorial*THIS SITE NO LONGER EXISTS...*]) to split up the two sides that are next to each other, but how big is a player ? look at the pic. (a player is 128 units tall, 64 wide, the white brush is how big the player is)

[9]

So delete the two smallest blocks (select tool, and click on it in 3D view, the hit the delete button), this is where you will be passing trough, place some walls and a floor and roof so u have the corridor like this:

[10]

That is really it, you now have two rooms, with a light in it, an start points in one of the rooms.
