Tutorial - How to combine multiple collisionfiles?

Since the availability of Steve's new CollisionFileEditor, it's easy to create new collisionfiles for the Vehicles.col and therefore to create them for vehicles. But what to do if there are 10 different Vehicles.col? You need every single one to make the vehicles work properly, but you can only install one at a time! So you should combine multiple collisionfiles - how that works? You will get to know here, step by step!

Step 1: You need CollisionFileEditor, who already has it can skip this step and go to the next one. Who hasn't got it must go on reading here :) You find the editor at Steve's homepage in the download section (http://people.freenet.de/steve-m/download.html). If the program does not work, also get the suitable .DLL file, which you can also find there! Now extract the editor and the .DLL file into any directory, e.g. C:\ColEditor. Go into that directory and start the program by starting "CollEditor.exe"!

Step 2: As you have started "CollEditor.exe" you should see a screen like this one here:

Step 3: Now load the vehicles' .col file. Therefor go into the GTA3 folder, then into the Models directory and afterwards into Coll (GTA3/Models/Coll). Now open the .col file, in this case: vehicles.col. Now the editor should look like this:

Step 4: For example your vehicles.col is the one of the flatbed with the ramp, but you also want to get the collisionfile of the Opel Speedster, which is in the archive of the Opel, into this one. We first check what car is replaced by the Opel, because this is the vehicle which has the new collisionfiles in the vehicles.col. So we have look into the archive to find out the names of the .TXD and .DFF file. Their names are Stallion.dff and Stallion.txd, so the Stallion will have been modified in the .col file, so you click on Import in the Editor. This window should appear:

Now you scroll down, select Stallion and click on IMPORT. It should look like this:

Because the position of the new colfile is the last one, the next step will be alot easier.

Schritt 5:

Now you have to delete the old colfile of the Stallion, because the game can't choose the right colfile and it would just crash :) So you delete the old Stallion colfile, which is easy to discriminate from your new one, because the new one is at the end of the collisionfile. So you look for the old one and there it is:

Now you click onto delete. The old Stallion file now is deleted and the new one active, so you have combined two collisionfiles. Everything should look like this:

Of course collisionfiles can look different from this one, because every vehicle looks different ;) So this is finished you just have to choose Save and save the file into the GTA3/Models/Coll folder. This is being acknowledged and you're finished! Now you can play the game with both collisionfiles, combined in one...
I hope the tutorial was helpful. It will really be useful because there will be lots of new collisionfiles for every kind of car, and you don't want to leave a car out. But you should always use a collisionfile when it's included with a car. If not, the car might touch the ground all the time and things like this. And you wouldn't want to leave a car out, just because you have multiple vehicles.col, would you? This is the reason why this tutorial exists. I allow EVERYONE to include this tutorial with their cars, if it uses a custom collisionfile, so it's most comfortable for every GTA3 gamer ;) But remember that my name remains in this tutorial! I hope this Tutorial was useful!
