title = "Updating to 1.11.2"

If you're updating from 1.10.2 to 1.11.2, there are a couple of things you need to be aware of:
|
||
|
|
|
||
|
|
## `ItemStack`s are _never_ `null`
|
||
|
|
Starting in 1.11, `ItemStack`s can _never, ever_ be `null`. Instead of checking for `null`-ness, you use the `ItemStack.isEmpty` method to make sure the stack contains something.
|
||
|
|
|
||
|
|
## `ItemStack` private fields
|
||
|
|
In 1.11, the `ItemStack.stackSize` field was made private. Instead of directly modifying this field like before, there are getter, setter, and mutator methods available.
|
||
|
|
|
||
|
|
- `getCount`: equivalent to simply retrieving the field.
|
||
|
|
- `setCount`: equivalent to setting the field
|
||
|
|
- `grow`: equivalent to increasing the field.
|
||
|
|
`stack.grow(1)` is equivalent to `stack.stackSize++`.
|
||
|
|
- `shrink`: equivalent to decreasing the field.
|
||
|
|
`stack.shrink(1)` is equivalent to `stack.stackSize--`.
|
||
|
|
|
||
|
|
**Note:** The default Forge MDK comes with older MCP mappings in which the new `ItemStack` methods aren't named. You'll need to change the mappings version from `snapshot_20161111` to the latest (`snapshot_20170330` as of this post).
|
||
|
|
|
||
|
|
## Resources
|
||
|
|
In 1.11.2, Minecraft enforces all resource file names being completely lowercase. This practically enforces `snake_case` instead of `camelCase`. You'll need to rename all your resource files (blockstates, models, textures, etc.) and change all the corresponding uses of their old names in code.
|
||
|
|
|
||
|
|
## Other
|
||
|
|
Aside from those major changes, there are a couple of minor things:
|
||
|
|
|
||
|
|
- `CreativeTabs.getTabIconItem` returns an `ItemStack`, not an `Item` now.
|
||
|
|
- Various mapping changes throughout the MC codebase. You can search on [here](https://github.com/ModCoderPack/MCPBot-Issues/issues) to see mapping changes in 1.11.2.
