Nodeflow

# Nodeflow Nodeflow is a library for graph based programming interfaces in minecraft on the fabric modloader.

## Getting Started Add a dependency on the library from jitpack. You can also use the modrinth maven, but you might end having to manually add a dependency on mixin extras then. ```groovy repositories { maven { url 'https://jitpack.io' } }

dependencies { implementation 'com.github.mattidragon:nodeflow:$nodeflow_version' } ```

To get started you will want to create a `GraphEnvironment`. Most mods will only ever need one, but if the available nodes change, feel free to create one every time. ```java public static final GraphEnvironment ENVIRONMENT = GraphEnvironment.builder() // Adds context that nodes need to execute. Stays same during each evaluation .addContextTypes(ContextType. SERVER_WORLD, ContextType. BLOCK_POS, ContextType. SERVER) // Datatypes that are allowed to be used. Exists for nodes that can act on any data type to know which ones are allowed .addDataTypes(DataType. BOOLEAN, DataType. NUMBER, DataType. STRING) // Adds groups of nodes at a time. They are also used for grouping in the editor. .addNodeGroups(new TagNodeGroup(NodeGroup. MATH), new TagNodeGroup(NodeGroup. ADVANCED_MATH), new TagNodeGroup(NodeGroup. LOGIC), new TagNodeGroup(ModNodeTypes. REDSTONE_GROUP)) // Adds single nodes. They will be placed in a misc group. .addNodeTypes(NodeType. TIME) .build(); ```

Using this environment you can create a `EditorScreen`, although you usually don't have any use for the base class.

If you are using a block entity for holding your code you can make it implement `GraphProvidingBlockEntity` in addition to extending `BlockEntity`. This interface already implements `ExtendedScreenHandlerFactory` so all you have to do is open the screen from the block entity. Nodeflow will handle syncing the graph on change.

If you aren't storing the graph in a block you can create a subclass of `EditorScreen` and handle syncing yourself (or not if you are fully client sided).

Proper javadocs and a wiki might come in the future.
