Permitted datavalues from block-tileentitys

Botjoe · January 27, 2015

I am trying to find out how to get the permitted datavalues from TileEntity classes before they are drawn (rendered or instantiated). Stairs specifically must rotate in a fill statement before placement.

I am pretty sure getValidRotations isn't what I want here.

My use case is to rotate the objects in a command set (my mod supports multi-line command sets as components along North,South,East,West) before it's executed. If the commands has a fill or set block of objects like stairs or wood, I need to rotate the data values. My problem is that datavalues aren't consistent for rotation for all types of blocks. That is- the rotating of minecraft:stone_stairs or yourmod:stairs from a south orientation is different from the values in rotating wood which is different from wall. The mod's command ExecuteFile can have any command including itself.

Walls have datavalues of 2-5 - Rotating a south (value) wall to the right in the fill command changes the datavalue from 2 to 4.

Stairs have 0-15 - Rotating from south to west changes the value from 0 to 4.

Nothing consistent.

In my use case, the files can also invoke files. That means rotations in the mod must also allow cascading with other components. Teleports, blockdata, etc all must rotate and the rotation must cascade.

I need a scheme for getting block rotation changes data values, BEFORE I run commands.

Hoping this is built in and I missed it. Otherwise I code and config the solution. but it's preferable (vastly preferred) to get some of all the block types rotations (classes) from vanilla and mods dynamically.

Hi

Bad news, I'm afraid... If you want that robustly, I suggest you migrate to 1.8 which uses BlockStates and facing to let you do this properly.

There is an inbuilt forge method in 1.7.10 (Block.rotateBlock()) but it's only good for rotating in place, it's useless for rotating metadata values.

I needed to do this for a mod of mine and in the end I copied the helper class from WorldEdit (on GitHub) which manually coded the values for every single block.

Sir, I am using 1.8 only, but it doesn't have what I need either.

Thank you for the timely reply

Then for robust configurability, It's information I need to read from the configurable file with types (Stair_type), and specific names "minecraft:stone_stairs" or Yourmod:your_stairs".

--------------------------------------------------------------

I'll post the code to read the configuration file when I write it with a helper function returning the new datavalue for rotation by forgedirection. --- I'll also create a command or api to add to the file so it's accessible for users, modders in the game.

----------------------------------------------------------------------------------------------------------------------------------

After the /ExecuteFile is sufficient, The next step is an /ExecuteOnEvent command for terrain generation events with a randomness percentage. My final use case is to give two simple commands that allow the average map maker or redstoner to have custom generation of cities, structures, and other things from "simple - easy to program" command files.

Ghost, I looked at https://github.com/sk89q/WorldEdit/blob/master/worldedit-core/src/main/java/com/sk89q/worldedit/blocks/BlockData.java. I'll probably extend the code differently and hook it to a generic type.

It's close, but it's not configurable for any other custom mod's blockdata.

I realized on reading it, I would need to allow modders with custom commands to add to the command types of rotation for my mod. No reason to do the same hard coding as blockdata.java. BlockId's aren't stable across mods, so more thinking is required.

---------------------------------------------------------------------

I'm not clear on how mods should communicate capabilities to other mods in forge.

I'm using the following for now.

BIG Thank you Grey Ghost

that's got it for now. Just vanilla, but enough for the moment.
