There is a mod that I decided to update to 1.9 as a learning exercise to get my feet wet with minecraft modding.

 

I currently get these errors when I compile:

I've managed to track down most the errors before this, but these all seem to be about changes to the code.

 

I don't just want someone to tell me the changes I need to make, I'd also like to learn how to figure it out for myself.

Any help is apprciated!

These are mostly classes that have been renamed in recent versions. You can search the issues of this repository for the old class name to find out what it was renamed to. This will work for most classes that were renamed in 1.9, but may not work for earlier versions.

 

  • AxisAlignedBB#fromBounds

    was removed when the class's constructor was made public. Use the constructor instead of

    fromBounds

    .

  • Vanilla removed the
    WorldProvider#dimensionId

    field and its getter method in 1.9 and replaced them with the

    DimensionType

    enum and the

    WorldProvider#getDimensionType

    method. Forge re-adds the

    WorldProvider#dimensionId

    field, but the getter is now called

    getDimension

    instead of

    getDimensionId

    .

  • WorldRenderer

    was renamed to

    VertexBuffer

    , so

    Tessellator#getWorldRenderer

    was renamed to

    Tessellator#getBuffer

    .

  • MCPBot tells me that the SRG name of
    StructureStart#getComponents

    in 1.9 is

    func_186161_c

    and it was given the name

    getComponents

    two days after Forge's default 1.9 MCP mappings were generated. Either use the SRG name or update your mappings.

  • MinecraftServer.getServer

    is no longer a static method. There are several methods that you can use to get the

    MinecraftServer

    instance now, use IDEA's Find Usages (or Eclipse's equivalent) feature to search for methods with return type

    MinecraftServer

    . In particular, you can use

    World#getMinecraftServer

    on a server-side

    World

    or

    FMLCommonHandler#getMinecraftServerInstance

    (prefer using the

    World

    method when possible).

  • ServerConfigurationManager

    was renamed to

    PlayerList

    , so

    MinecraftServer#getConfigurationManager

    was renamed to

    MinecraftServer#getPlayerList

    . The

    PlayerList#playerEntityList

    field is now private, use the

    PlayerList#getPlayerList

    method to get it.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
