How to make Rotatable Block [VIDEO TUTORIAL]

Started by Nuparu00 on Sun, 09/25/2016 - 16:43

Hi. Because there is not his feature in MCreater itself and many of you need it for your mod , I decided to make a video tutorial how to make custom block rotatable , using PropertyDirection.

Hi,

I am using 1.12.2 and it didn't work even with the code for +1.9.

Could you please send the code of one and the same simple block with and without rotation so that I can see exactly the difference and I can apply it to other blocks as well? I would be very grateful for that!!

Jump to top Permalink

Yeah, please, can you make update to new version?

Jump to top Permalink

I put the code you metioned and in the game there is no texture.

Jump to top Permalink

Did you edit the blockstate .JSON file? And if yes, are there any error/warning messages in the log?

Jump to top Permalink

Yes, I edited the blockstate.json. But today I rewrited the code giving me the purple block by your example code from one of the video commentaries (https://pastebin.com/Exp7HuUn). And the client doesn't even start. Now I got two errors:

C:\Pylo\MCreator179\forge\build\sources\main\java\mod\mcreator\mcreator_sipka.java:55: error: register(K) has private access in GameRegistry
      GameRegistry.register(block);
                  ^
  where K is a type-variable:
    K extends IForgeRegistryEntry declared in method register(K)
C:\Pylo\MCreator179\forge\build\sources\main\java\mod\mcreator\mcreator_sipka.java:56: error: register(K) has private access in GameRegistry
      GameRegistry.register(new ItemBlock(block).setRegistryName(block.getRegistryName()));
                  ^
  where K is a type-variable:
    K extends IForgeRegistryEntry declared in method register(K)

Meantime I solved the rotation by creating 4 blocks (each is facing different direction) and by making 4 procedures which changes one block for another by clicking. But I think the coding would be more elegant.

What version of Minecraft are you modding for? If you are using 1.12.x+ , you can not register the block in the same way as in the version that the code sample was for. I guess I have to update the video someday...

Jump to top Permalink

I use 1.12.2. First time I used the code for 1.9 (right bellow the vid) and put the changes for 1.10, 1.11 and 1.12 from commentaries. Then the game worked but textures were missing. Later I thought the sample code was for 1.12 so I tried to use this. And that happened. Never mind, I use the procedure system now. Updating the code system would be great for 1.13 and newer versions. And thank you for your attention.

this.setDefaultState(blockState.getBaseState().withProperty(FACING, EnumFacing.NORTH));

Is supposed to be in the constructor of your blocks class, it can not be on its own in the class.
