Ok. so i know now how to edit a cube to stair for example, and how to make walls and floor, but not sure if its the right way =)
But still, i dont know how to create a sky or any secret that will be hidden behind a wall or under stairs. And still dont know how to run the damn map!
Oh, i would like to know how to add the staring place too..

Thanks anyways, even if you havent answered yet. lol!

Hi Sampoo,

Tread edits multiple games, and unfortunately each one is different. The questions you are asking are mostly related to the specific game in question. I recommend looking around the web for tutorials on editing the game in question.

As far as basic modeling in the editor, you can resize brushes using the grip handles in the 2D views, or using the gizmo's in the 3D view. Climable ladders and other brush objects are done by "Linking" the brush to an entity. Select your brush and right click, and goto the Link To Entity submenu.

To run the map, you need to configure the game in question under one of the main menu's (I forget which one off hand). Enter the location of the executable and other information. After that you should be able to run the game using the Run Game option under one of the main menus.

Hope that helps!

Quake 2 uses special texture values for its brushes for content, like liquid or solid, and for surface properties, like slick or sky.
I don't know whether Tread supports these special brush properties, but ladder is one of the brush texture properties, in the same way that water or sky is.
If Tread can't do these important Quake 2 texture properties, then I suggest finding another editor like Worldcraft(if it works with your graphics card) or requesting that these features be put in. As it is, I can't find a way to do it in Tread.

For a level ending point:
1. Make a brush.
2. Link the brush to a Trigger Level Change entity (right click on brush and go to Link to Entity> Triggers> Trigger Level Change or something similar depending on the game).
3. You can change the map name in the properties on the right, just select it from the drop down list.

When you touch the trigger in game it will end the level and change to the next map, if there is no next map then it will just go to the console or main menu.

For the Additional Command Line:
This depends on your compiler, that is your qbsp light and vis programs(these names should be slightly different for Quake 2 than Quake but I can't remember what they are... anyhow)
With vis you can add a parameter to have it to a quick sloppy job or a full complete compile: -level x (where x = either 1,2,3, or 4, I'm not sure what no parameter is, but it's probably 1)
With light you can add a parameter to have it either do normal lighting, or extra: -extra (normal is with no parameter)

For secret areas:
1. Make a brush.
2. Link it to an entity similarly to above. This time it's Link to Entity> Triggers> Trigger Secret or something similar.
3. Change the properties to your liking.

4. As for making secret doors or walls:
a. Make your secret room with more brushes (this is where you put your trigger secret in).
b. Make an opening to it.
c. Make a door to fill the opening.
d. This door must be a Link to Entity> Door or Secret Door
e. Change the properties of the door to have a "health" of at least "1"
f. In-game when you shoot or whack the door, it should open in the set direction. Play around with it until you get it how you like. The texture for the door can be the same as the walls around it, but with a rotation of about 10 to make it more hidden, or the texture can be something like a light or vent or whatever.

An elevator is made similar to a door:
1. Make a brush.
2. right click on it, Link to Entity> Elevator
3. The properties set things like travel height and damage done to things under it.

Also for adding command line options, look in the base folder (which should be where the Tread.exe is), and look at the quake.opts and quake.txt files.
