## ModAPI.keygen
|
||||
ModAPI.keygen contains the API for getting item and block IDs from a string. It looks at the registries for items and blocks to derive the IDs, so IDs will not be automatically reserved until a block/item is actually registered. Ideally, you'd want to call a keygen method just before registering your block.

ModAPI.keygen contains the API for getting numerical item, block and entity IDs from a string. It looks at registries to derive the IDs, so IDs will not be automatically reserved until a block/item is actually registered into the game. Ideally, you'd want to call a keygen method just before registering your block.
|
||||
|
||||
Methods:
|
||||
- `ModAPI.keygen.item(itemId: String) : number`
|
||||
- Example usage is: `var id = ModAPI.keygen.item("my_example_item");`
|
||||
- `ModAPI.keygen.block(blockId: String) : number`
|
||||
- Example usage is: `var id = ModAPI.keygen.block("my_example_block");`
|
||||
- Example usage is: `var id = ModAPI.keygen.block("my_example_block");`
|
||||
- `ModAPI.keygen.entity(entityId: String) : number`
|
||||
- Example usage is: `var id = ModAPI.keygen.entity("my_example_entity");`

@ -16,9 +16,10 @@ Methods:
|
||||
- This method is used to find a class by its id.
|
||||
- For example, to get the `Minecraft` class, you can use `ModAPI.reflect.getClassById("Minecraft")`
|
||||
- This runs slower than `getClassById` because it has to filter through all classes. Make sure to cache the result rather than calling it over and over again.
|
||||
- `ModAPI.reflect.getSuper(rClass: ReflectClass, filter: Function) : Function`
|
||||
- `ModAPI.reflect.getSuper(rClass: ReflectClass, filter: Function?) : Function`
|
||||
- Gets a super function from a reflect class. This is used to extend built in classes, like `Block`.
|
||||
- For an example, see lines [29](https://github.com/eaglerforge/EaglerForgeInjector/blob/6e8598c180f96a65c0c101be72e6d0fa53195404/examplemods/unlucky_blocks.js#L29) and [33](https://github.com/eaglerforge/EaglerForgeInjector/blob/6e8598c180f96a65c0c101be72e6d0fa53195404/examplemods/unlucky_blocks.js#L33) in unlucky_blocks.js

- For an example, see lines [29](https://github.com/eaglerforge/EaglerForgeInjector/blob/6e8598c180f96a65c0c101be72e6d0fa53195404/examplemods/unlucky_blocks.js#L29) and [33](https://github.com/eaglerforge/EaglerForgeInjector/blob/6e8598c180f96a65c0c101be72e6d0fa53195404/examplemods/unlucky_blocks.js#L33) in `unlucky_blocks.js`
|
||||
- When called without a filter function, the filter defaults to `(fn)=>fn.length === 1`
|
||||
- `ModAPI.reflect.prototypeStack(rClass: ReflectClass, target: Class/ConstructorFunction) : void`
|
||||
- Copies methods from a reflect class and it's parents onto a target native JavaScript class. This allows TeaVM to use these objects normally, without you having to manually reimplement every method. In other words, this is the equivalent of extending a class.
