These callbacks are what the game uses to trigger logic around events that happen in the game. Next, we will begin setting up some various callbacks. MyMod.COLLECTIBLE_MY_ITEM = Isaac.GetItemIdByName("My Item") This will make it easier reference them throughout our code. Next, let's make some references to the item that we are creating and attach them to our mod.

A reference to our mod is then stored in the MyMod local variable that we can now use within our code.Īs an additional convenience, we've also created a game variable to reference the game class. This registers our new mod by passing in a string of "My Mod" and 1, which sets the name of our mod and the API version we're using. Inside of the file, we'll first register our new mod and set a reference to the game. In the root directory of our project, create a new a file. To do this, we need to add in some logic to tell the game which stats we would like to increase and by how much. Our item is going to do basic stat updates for the player, similar to the various items already in the game that give increase all of your stats. Just make sure that the image filename is exactly what you set as the value in the gfx property of the item in the items.xml file we created above. Making the image from scratch is well beyond the scope of this tutorial, but all you need is to have an image that is 32px-by-32px and place it into the resources/gfx/items/collectibles/ directory that we created earlier. Once you have successfully added your items.xml file, we can now add in an image file for our item.

So, in this case, we wish to give the player 3 full soulhearts so we must double the number assigned to this property. It is important to note that this numeric value corresponds to the smallest heart unit: the half-heart. The soulhearts property values reflect how many soul hearts we would like to give to the player when they pick up this item. You will provide a corresponding cache value for every stat that you wish to modify. The cache property values are used to trigger stat changes for the player. Next, we have a couple function properties cache and soulhearts. These will be used directly inside of the game when the player picks up the item. On this element, we provide all of the necessary properties that that game will use.įirst we provide it a name and description. Inside, we added a new element which signifies that we are creating a passive item (for reference, the other options are and ). įor the element, we just need to provide the root directory to find the graphics files that we will be using and the version of the API. Unlike the resources directory, this breaks the pattern of mimicking the same location the the game already uses. This file has to be located inside of the content directory to work properly. This file will contain the basic information for the item that we are creating in addition to a reference to the graphic that we will be using for it.
Next, inside of our content directory, we will need to create a new file named items.xml. We're essentially mimicking this structure so that the game knows where to find our files and pull them into the game. The reason that we have to structure the resources folders in this way is because they directly map to the folder structure that the game already uses. When done, our directory structure should look like so: - my-mod/ Inside of our resources directory we need to add a few more folders. In our case, we're going to be creating an item - so our mod will require a folder named content a folder named resources. This new folder requires a few files and a specific folder structure to actually work correctly. ~/Library/Application Support/Binding of Isaac Afterbirth+ Mods/ WindowsĬ:\Users\YourName\My Games\Binding of Isaac Afterbirth+ Mods\

The first step to making a new mod is to navigate to your mods directory and create a new folder. In this article, we're going to take a look at The Binding of Isaac: Afterbirth+ modding API and go over the basic steps to create a simple item mod for the game.
