To do most things with .scs files all you need is a compression agent. I happen to use 7zip because it is easy to use, flexible and free
1. Download It!
2. Install it
3. Set 7zip (or your compression agent) to be the default program opening .scs files <----REALLY GOOD THING TO DO IF YOU PLAN ON MESSING WITH LOTS OF .SCS FILES!!!
In Windows XP:
1.Open windows explorer
2.Click on the "tools" tab
3.Click on the "folder options" menu tab
4.Click the "file types" tab
5.Click the "new" button
6.Fill out the form with the appropriate associated program
MOVE ON TO THE NEXT STEP!
Finding & Unzipping the Base.scs file
1. Make sure you have administrator privileges or can navigate through system files.
2. Navigate to C:\Program Files (where C: is your main drive)
3. Click on the "18 Wheels of Steel Haulin" folder
4. Use 7zip (see above) to open "base.scs"
5. Extract base.scs to a folder called "base" in your "C:\Program Files\18 Wheels of Steel Haulin" folder
Finding the definition files1.
1.Open the .scs file of the truck you want to install, then extract it's contents to your desktop in a folder called: "Haulin' truck storage"
2. Inside the haulin' truck storage folder, click on the extracted folder called "vehicle"
3. Click on the folder called "truck"
4. Click on the folder called "definition"
5. You should now see one file (or more) that have the extension .sii
6. In a new window (don't close the old one) open up the directory of the "base" folder you should have created
7. Click on the "vehicle" folder inside the "base" folder
8. Click on the truck folder
9. Scroll down to the bottom of the "truck" folder, you should now see two .sii files
10. Highlight the "truck_storage.sii" file and copy it
11. Open your old window back up and click the back until you are in the "Haulin' Truck Storage" folder
12. Create a new folder inside it called "truck Storage file"
13. Create a new folder inside that folder called "vehicle"
14. Create a new folder inside that called "truck"
15. Paste the "truck_storage.sii" file there
16. Open the "truck_storage.sii" file with notepad
It should look like this:
Pretty intimidating, huh?
17. Go back to those definition files we found in the truck you want to install
18. Copy ALL of one of the file names
19. Type a new line directly below @include "definition/ws.sii" using this template:
@include "definition/put the name of the def file here"
20. Keep adding new lines for all of the trucks you have.
Note: DO NOT USE ANY FILES LABELED AS TRAFFIC, those are for a different purpose
21. Once you have added all the lines you want for your trucks, save the file
Creating .SCS files
1. Open up the "truck Storage" folder using 7zip (click on the 7zip icon, then navigate to the folder
2. Click on the "vehicle" folder ONCE!
3. Click the "add button on the tool bar at the top of the screen, A dialog box will pop up
4. Configure Zipping options
Set Archive Format to Zip
Set Compression level to store
5. In the "archive" box at the top of the screen, type in the name of the file you want (for instance, truck_storage)make sure you put the name you want, and then add .sii to the end (truck_storage.sii for instance)
Note: there is a myth out there that files need to have the extension .scs for haulin' to recognize them, but this is NOT true. If you have used the proper compression method, the computer should accept .zip extensions just as well as .scs extensions. To avoid confusion however, it's best to name your files.scs by re-naming the file extension
6. Click "OK"
7. Make sure that you move all appropriate .scs files into your mod folder before starting a game, otherwise it will crash
Enjoy your new trucks!
