I created a new flower for my mod and I can generate it in a custom biome but how do I generate it so it spawns on biomes already in the game? Also is there a forge hook that allows a custom flower to spawn when bonemeal is used on grass? I'll be thankful for any help.

Ahoj.

 

I was hesitant to post this at first, because, knowing my coding habits, this is probably the worst way to do something like this. You have been extremely patient though, so I'll give you something you can at least start on.

 

 

You can use this:

 

                        BiomeGenBase biomegenbase = world.getWorldChunkManager().getBiomeGenAt(chunkX, chunkZ);

                        if(biomegenbase instanceof BiomeGenPlains)

 

and then your "for loop"

 

 

I hope this helps a bit.

I have an intermediate knowledge of java but where do I put that code? In my main class, flowerPineapple class or my world generator class?

Oh, I'm sorry. I was in a hurry at the time of writing that. :'(  You put it in your world generator class.

I'm at a loss when it comes to fixing things in forge. Should it look like this?

                BiomeGenBase biomegenbase = world.getWorldChunkManager().getBiomeGenAt(firstBlockXCoord, firstBlockZCoord);
                if(biomegenbase instanceof BiomeGenDesert)
            	for(int l = 0; l < 10; l++){
            		int x = i + random.nextInt(16);
                	int y = random.nextInt(30);
                	int z = j + random.nextInt(16);
                	(new WorldGenMinable(PenguinMod.flowerPineapple.blockID, 4)).generate(world, random, firstBlockXCoord, firstBlockYCoord, firstBlockZCoord);
            	}

Just don't check for a biome at all. Also, tweak your block so that it can spawn on anything. Unless you don't want it to spawn on everything, just make it spawn on BlockGrass. Most other mods' grass blocks will extend BlockGrass.

Don't use WorldGenMineable. It's for replacing (stone) blocks with other (ores).

Make a seperate class for your flower.

 

It will look something like this...

and then change

(new WorldGenMinable(PenguinMod.flowerPineapple.blockID, 4)).generate(world, random, firstBlockXCoord, firstBlockYCoord, firstBlockZCoord);

           

to

 

(new WorldGenYourFlower()).generate(world, random, RandPosX, RandPosY, RandPosZ);

       

Like I said, I have bad habits. I don't always do things the "best" or "most efficient" way. If it works; it works. I guess thats what happens when you are almost entirely self taught. ¯\_(ツ)_/¯

 

 

EDIT: ^ What GoTo said. Hi GoTo.

As far as I'm aware the code is correct an I have no errors but the pineapple won't spawn. Is anything wrong with my code? Thanks for all the help so far.

FlowerPineapple:

package TylerWatson.Mod;

import net.minecraft.block.Block;
import net.minecraft.block.BlockFlower;

public class FlowerPineapple extends BlockFlower{

public FlowerPineapple(int par1) {
	super(par1);
}
    public boolean canThisPlantGrowOnThisBlockID(int par1)
    {
        return par1 == Block.grass.blockID || par1 == Block.dirt.blockID || par1 == Block.sand.blockID;
    }

}

I think I have your solution.

 

First, where are you getting "firstBlockXCoord, firstBlockYCoord, firstBlockZCoord" from? How is Eclipse not screaming at you? Switch them out for "x, y, z" respectively.

 

Second, change the number in "for(int c = 0; c < 10; c++)" to something higher, like.. "for(int c = 0; c < 80; c++)"
