how do i add my custom tulips to a vanilla-biome?

Drachenbauer · March 2, 2020

Hello

I have created my own tulips to compleete a 16 colors set.

I can put them on the ground and into a flowerpot.

But how do i add them to s vanilla-biome?

I don´t know, where in that huge vanilla-code library i can find the matching code...

Use DeferredWorkQueue to add features to the biomes you want during the FMLCommonSetupEvent.

Check out classes in the net.minecraft.world.gen.feature package and the DefaultBiomeFeatures class in net.minecraft.world.biome.

I´m not sure, how to use DeferredWorkQueue

Should i make a method like in DefaultBiomeFeatures and call it in the FMLCommonSetupEvent.

Ugdhar · March 2, 2020

Search the forums for "runLater", and you will find examples/discussion how to use DeferredWorkQueue, but essentially yes.

Now i have this in my FMLCommonSetupEvent:

        DeferredWorkQueue.runLater(() ->
        {
            addModTulips(biomeIn);
        }
        );

But i´m not sure, how to put a specific biome into my method-call...

I don´t know, where the methods are called, wich i found in DefaultBiomeFeatures...

I must find this to see how a biome is given in there...

should i do it as a new instance of the biome-class?

now i found, what i looked for.

time for a test in a world with a flowerforest biome nearby.

Edit:

this is now my main-class:

   }
}

I made a method, that should ad my tulips to the flowerforest biome.

For a first test, it only includes the black tulip now.

But as i created a flower-forest-world, i cannot find any black tulips in there...

This should be done in FMLClientSetupEvent, not common.

some posts above, an user told me to work in common.

The fact that the first line does not produce a NullPointerException suggests that you are also incorrectly initializing your blocks in a static initializer. You cannot do that. Please use DeferredRegister to register your Blocks.

If i registered my blocks wrong, why i can place them in a world and plant the tulips in pots ?

Yes, regarding adding the biome features...

Do you mean the lines for making the tulips transparent should be in client?

I thaught, you mean my biome-thing.

Spoiler

You cannot initialize these things here.

where else should i initialize them?

Drachenbauer · March 3, 2020

Now i register my blocks and items like shown in the sample in the "DeferredRegister"-class.

Can i remoce the integrated "RegistryEvents"-class from my main-class, if i finished the new way to register my stuff?

Can i put the lines for the single blocks and items, like:

    public static final RegistryObject<Block> BLACK_TULIP_BLOCK = BLOCKS.register("black_tulip", () -> new FlowerBlock(Effects.WEAKNESS, 9,
                        Block.Properties.create(Material.PLANTS).doesNotBlockMovement().hardnessAndResistance(0f).sound(SoundType.PLANT)));

into my blocks- and items-classes, where i already had them listed?

Yes, but you need to register the modbus or something else in your main class (am writing from mobile and have forgot the name). If you still need help then pls provide a link to your Github

Edit:

i think i found it now, saw, that the yellow tulip at the blocks registry had the registry name "purple_tulip".

fixed it now and test it

Now it works.

I created a new flower forest world and started directly in a patch of my own black tulips.

Now i just have to register the other tulips to biome the same way.

Edit:

Now i modifyed my Config-line for the biome, that it makes patches with a mix of all my tulip-colors.

Now i hace some more questions:

Where are the Blockstates from the vanilla-tulips?

I want to add them to my mixed tulip patches, too.

How can i make, that only my code adds tulips to the biomes?

see vanilla (the third .jar file, the extra-client.jar file)

Drachenbauer · March 3, 2020

private static final BlockState DANDELION = Blocks.DANDELION.getDefaultState();

I mean code-lines like this for the tulips.

This sample is the one for the dandelion and is located in the DefaultBiomeFeatures..

Or can i write my own into my code?

Now i´fe written my own lines of this.

How can i now make only my code generate tulips in the biomes?

I want to use my code for all biomes with tulips.

My idea is to use the set BIOMES in the class Biome and make a for-loop, that goes through the biomes:

for (Biome biome : Biome.BIOMES)
{

}

And inside therei want to check for tuips in the biomes and if yes, use my code..

For this i have a question

How can i check, if a biome has tulips?

Edited March 3, 2020 by Drachenbauer

Drachenbauer · March 3, 2020

Now i try this to check for tulips:

        DeferredWorkQueue.runLater(() ->
        {
            for (Biome biome : Biome.BIOMES)
            {
                /*if (biome.getFlowers().contains(o))
                {
                    
                }*/
                System.out.print(biome.getFlowers());
            }
            
            addModTulips(Biomes.FLOWER_FOREST);
        }
        );

At first i want to use an output to see, how the content of the flower-list looks.

But i find no result in the console...

Do i just not know, where in the console output i have to find output from the common-setup?

Or is there any reason, that this gives no output?

In another mod i used this output-command in a model-class and found it´s output in the console.

No, i think you should see the Json Blockstate.

This not wonder me, you have used system.out.println(), but in modding you muss use the Logger.

Drachenbauer · March 4, 2020

Now i have this:

This looks like Flower Forwst does not appear in the biomes-list...

and i still don´t know, what i should place intead of the "flower" in this code:

                if (biome.getFlowers().contains(flower))
                {
                    
                }

to check, if it for sample contains red tulips...

Edit:

in a Minecraft wiki, i saw, that tulips only appear in Plains, Sunflower Plains and Flower Forest.

Is this right?

If Yes, i simply can use 3 lines of my methode-call with theese biomes given as param.

In a wiki i saw, there are only 3 biomes, wich contain tulips.

If this is right, i think, i just can three times call my method and give theese biomes as arguments.

Drachenbauer · March 4, 2020

I also think, biomes in mods may have the tulips added a bit different to the vanila-ones.

This can make it more difficult to check all biomes, that may appear in mods...

I also have a new question:

Can i have my block and item-registries separated into two init-classes?

In the vanila-code has a class Items, where all items are initialized.

And a class Blocks, where all blocks are initialized.

I have similar classes in my mod, too.

So i thaught, i can put the block-registrys into my blocks-class and the item-registrys in my items-class.

But now i get an error:

Quote

java.lang.NullPointerException: Registry Object not present

How can i make theese registrys work, if they are in separate classes?

Edit:

Now i found the solution:

Theese lines:

public static final DeferredRegister<Block> BLOCKS = new DeferredRegister<>(ForgeRegistries.BLOCKS, Reference.MOD_ID);

needed to be in the separate classes, too.

You answered, while i edited my post:

Now i found the solution:

Theese lines:

public static final DeferredRegister<Block> BLOCKS = new DeferredRegister<>(ForgeRegistries.BLOCKS, Reference.MOD_ID);

and

public static final DeferredRegister<Item> ITEMS = new DeferredRegister<>(ForgeRegistries.ITEMS, Reference.MOD_ID);

needed to be in the separate classes, too.

Now it works.

Have you tried anything? Have you looked anywhere to see how vanilla stuff works?

I'd start with BoneMealItem and work back from there.

Drachenbauer · March 5, 2020

I looked into that item, but saw nothing about the flower-blocks there...

You can't give up so easy. Look at what happens when you use bonemeal, and follow the progression of code.

I did, and it lead me to notice it calls some methods from the IGrowable interface, which lead me to notice that when you bonemeal a block, the (IGrowable) block holds the code that is executed. That's as far as I got, I'll let you do the rest.

how do i add my custom tulips to a vanilla-biome?
