Adds tabs to access nearby blocks.
To add Inventory Tabs to your project, you need to add https://jitpack.io as a repo and com.github.cakewhip:inventorytabs:mcA.B.C-vX.Y.Z as a dependency. For example:
repositories {
maven {
url "https://jitpack.io"
}
}
dependencies {
modImplementation "com.github.cakewhip:inventorytabs:mcA.B.C-vX.Y.Z"
}
See the releases page for available versions.
There are multiple ways to add custom tabs.
A "simple block tab" is a tab that is opened via interaction with a block. If your block falls under this category, adding a tab is as easy as passing your block to TabProviderRegistry#registerSimpleBlock.
Chest tabs are tabs belonging to chests that are able to double up along the horizontal axis. To register your chest, pass the block reference to TabProviderRegistry#registerChest. Chests that do not match vanilla chest behavior should not use this method.
The first step to adding a custom tab is creating a class that implements the Tab interface. This represents the tab that players will see, and it also controls what happens when the tab is clicked.
The next step is to register a TabProvider using the TabProviderRegistry. TabProvider objects are called every tick while a screen is open in order to populate the list of tabs available to the player. The list is not managed by the mod, so be sure to check for duplicates yourself. The GenericBlockTabProvider class is provided, and serves as a basis for adding tabs for blocks that open handled screens (it also checks for duplicates for you). Feel free to see the EnderChestTabProvider and ShulkerBoxTabProvider classes for implementation details.
Your handled screen needs to update the TabManager, which you can grab a reference of by calling TabManager#getInstance. In the init method (not your constructor), you must call TabManager$#onScreenOpen. After doing that, you need to do a check to see if your screen was opened via tab or other means. If it wasn't opened via tab (check by calling TabManager#screenOpenedViaTab), call TabManager#onOpenTab with your Tab object. See VanillaScreenTabAdder for more details on how to do this. You can also adjust the y-axis positioning of the bottom row of tabs by setting TabRenderer#bottomRowYOffset (there is a reference to a TabRenderer object in the TabManager).
Finally, there are some methods to call for rendering and managing the tabs. In the render method before anything is drawn, call TabRenderer#renderBackground. In the drawBackground, call TabRenderer#renderForeground and TabRenderer#renderHoverTooltips. In the mouseClicked method, call TabManager#mouseClicked.
If your screen's GUI dynamically changes (in the case of a recipe book opening), you can implement the TabRenderingHints interface and offset the top and bottom rows however you like.
