Modding:JSON Patching: Difference between revisions

{{GameVersion|1.19}}

The first thing you need to do is to setup a generic mod as outlined on the wiki. That information can be found on the [[Mod Packaging|mod packaging]] page. In that example the domain is the name of your mod. Patching is considered a content mod but if you have a .dll or .cs in your mod it is a code mod. Patches go in assets/domain/patches.

Now that the mod files and folders are setup it is time to make the first patch. Start by making a .json and name it however you'd like. Open the file with your favorite text editor and fill it in with the following.

Now lets give an example. For these examples I'll be modifying the wolf-male.json because it was the first one I modified, I'm very familiar with it, and it provides a good basis for examples. In this first example, we'll modify wolf damage.

You can change the domain to modify other peoples mods as well.

Since wolves already deal damage we simply want to replace the damage value.

Within these square brackets, you'll find sections between curly braces. '''Curly braces { }'''

Now to break down the example. We see the value we want to modify on line 52. To get to that we trace it back to the first label which is '''server'''. From there the next label is behavoirs. Here we notice the square brackets, so we must count. In this case to 5. Next is the label '''aitasks''', then we hit more square brackets. The count for this is 0 because that's the number you start on. Finally we get to the label '''damage'''.

{ file: "game:entities/land/wolf-male", op: "replace", path: "/server/behaviors/4/aitasks/0/damage", value: 6},

At this point, you have all the tools for modifying assets using the patching system. This is an incredibly powerful tool that only limited by your imagination. Have fun patching!
