Locking Npc Animations

This is a quick guide to locking NPC animations for a custom model. As an example in this tutorial, we will use the Zombie Classic model. Only the decompiling process, locking the animations and recompiling will be covered.

Note:When in-game, animations created using this tutorial might move awkwardly. This tutorial is not supposed to make them move perfectly, but rather demonstrate the process. To make it look right, it will take some custom tweaking while moving the root bone.

Required tools

• Goldsource / Source engine
• StudioCompiler

Warning:do not use Cannonfodders stand-alone .mdl decompiler, it has a bug in it affecting decompilation of this file.

• 3DSMax / Cannonfodders 3DSMax .smd import/export plug-ins
• GCFScape
• Adobe Photoshop and VTF Import plugin

Creating a decompile directory to store your .smd, .mdl and texture files

1. On your desktop or where-ever, create a directory called decompile.
2. In your mod directory, open your models directory (if there isn't one, create it) and create a directory named Zombie.
3. Back in your mod directory, open the directory materials and create a directory named models. Under that directory create another directory named zombie_classic. It should now look like materials/models/zombie_classic.

Note:These directory names are case-sensitive. Please use the ones described here or you are likely to have problems further into the tutorial.

Extracting the zombie model and its textures.

1. Open GCFScape
2. Extract the zombie classic model found with GCFscape in Program Files\Steam\SteamApps\source models in the decompile directory.
3. Next, extract the zombie textures found with GCFScape in Program Files\Steam\SteamApps\source materials in the decompile directory.

Note:GCFScape will sometimes not open with Steam running in the background. If this happens, just close Steam.

Note:For the Zombie texture location, look in GCFScape under hl2/materials/Models/Zombie_Classic.

Opening the .VTF files with Photoshop and converting them to .TGA

You need to change the zombie textures you just extracted into targas for viewing later on.

1. Launch Photoshop
2. Navigate to file -> open
3. Scroll to your decompile directory and select Zombie_Classic_Sheet.vtf.
4. Navigate to file -> save as and save the document as a .targa file in the decompile directory.
5. Repeat the process for the normal map texture.

Note:Be sure NOT to load the .VMT file instead of the .VTF file.

Decompiling the model

1. Open Studio Compiler and select Model Decompile.
2. Next, in the choose model file line, select the blue directory icon and open the Classic.mdl file that you extracted in your decompile directory.
3. Under choose output directory, select the blue directory icon and browse to the decompile directory.
4. Click the extract button to decompile your model.

Note:You may have to type in the location of the model under choose model file.

You will notice in the directory you created (make sure you set studio compiler's mdl decompile to extract the files in the directory you just made) a bunch of files with the extension .smd and a text file with the extension .qc. It will be explained later — for now, we just need the .smd files.

Using 3DSMax

Note:Make sure you have installed Cannonfodders 3D Studio Max .smd import/export plug-ins into the 3DSMax plug-in directory.

1. In 3DSMax, navigate to File -> Import.
2. Select the .smd file type, navigate to the decompile directory and select the file Zombie_reference.smd. Click Open.
3. A window will pop up asking what you want to import. Check import triangles, import skeleton, prompt for missing textures, rebuild smoothing groups and click OK.
4. Another window will pop up asking for the textures you extracted earlier. Under file type, select .targa. Navigate to the decompile directory and select the .targa file you created earlier. Load the file.

Note:Be sure not to load the normal map image file! Your model should look like this.

Now you have your zombie model in the viewport.

Loading animation files

Now, for the part you all have been waiting for: how in the world do you lock the animations?

1. Navigate to File -> Import, scroll to the decompile directory and select a_walk1.smd.
2. This time when the Cannonfodders window pops up, uncheck all the boxes except import skeleton. You'll notice the figure change pose.
3. Scroll the time slider at the bottom to view the animation. You will notice that the model walks in one place, this is where the problem lies.

Note:If you happen to get a bone at the bottom of your model named smd import, delete it.

Moving the root bone

1. Press F3 on your keyboard to view the wire frame.
2. Zoom into the middle of the model's pelvis area and select the bone labeled ValveBiped.Bip01_Pelvis.
3. To ensure we have selected the correct bone, select the move tool and move the bone around the screen. The entire model should move with the bone. If it does not, try to select the bone again until the model moves with the selected bone.
4. Next, select all the time keys at the bottom of the screen.
5. Delete all of them except the first one.
6. Move your camera to the side of the model.
7. Press the auto key button at the bottom of the screen.
8. Move the time slider to the last key.
9. Using the move tool, move the model a few feet forward by the root bone.
10. Turn off auto key.
11. Scroll the time slider back and forth to view the animation. The model should move back and forth, instead of in one place.
12. Navigate to File -> Export. For file type select .smd. Scroll to the decompile directory and overwrite the existing file named a_walk1.smd.
13. Now import the remaining walk files labeled a_walk1.smd, a_walk2.smd, a_walkNE.smd, a_walkSW.smd, etc. and repeat the process to them. Make sure you overwrite all the walk animations with the new ones.
14. After overwriting all the walk animations with new ones, close 3DSMax.

Note:When working with animation files labeled with a SW, NW and so on at the end of them i.e. a_walkSW.smd, make sure you move the root bone into that direction. Example: move a walk animation labeled A_walkNE.smd into the north east direction, like so: before, after.

Editing the .qc file

1. In Notepad or similar, navigate to the decompile directory and open the .qc file as shown in the picture.
2. This step is the most important. We will now officially lock the animations. After every animation line, you have to add the text LX LY.
3. Paste the following code in your .qc file and close it.

Testing your model

Congratulations! You've just completed your first NPC with locked animations. The easiest way to view your models is to make a shortcut to model viewer on your desktop and drag the files onto it.

1. Navigate to your Source SDK binary directory at ...\Steam\SteamApps\yourname\sourcesdk\bin.
2. Select the program named hlmv and right click on it.
3. Select Send to and click Desktop (create shortcut). A shortcut is now on your desktop.
4. Navigate to your models directory in your mod's directory.
5. Open the Zombie directory.
6. Select the model Classic and drag it onto the hlmv shortcut. The model viewer opens.
7. Under the Render tab, select the Ground checkbox.
8. Select the Sequence tab and select the walk animation.
9. The ground underneath the model should now move, which means that the model will change position in game.
