Hey guys,

I made a few new plants and now I wonder how I can get them to spawn just like minecraft flowers

Thanks in advance

Have you ever made an IWorldGenerator for ores? It's the same thing, but use WorldGenFlowers instead of WorldGenMineable.

unfortunatly not, you know a good tutorial on that?

Add this to you initializationEvent: "GameRegistry.registerWorldGenerator(new RPGGenerator(), 1);".

But use instead of my class a new class that implements IWorldGenerator.

If you have eclipse, you can use "add unimplement methods" to get the method you will have to use.

That method is called every time a new chunk is generated, I hope I have you told enough.

Have a look here on how to make a worldgen class. Look where I use WorldGenWaterPlants, it's very similar to WorldGenFlowers.

Alright Thanks so far, but I get a crash

Dont know why it wont work, only thing im not too sure about is where to register my generator? (currently in my preInit)

There's my code :

 

public class PlantGenerator implements IWorldGenerator
{
@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {
	if(world.provider.dimensionId == 0) generateFlowers(world, random, chunkX*16, chunkZ*16);

}

private void generateFlowers(World world, Random random, int x, int z) {
	for(int i = 0; i < 3; i++){
	int xCoord = x + random.nextInt(16);
	int zCoord = z + random.nextInt(16);
	new WorldGenFlowers(Blocks.red_flower).generate(world, random, xCoord, world.getHeightValue(xCoord, zCoord), zCoord);
	}
}
}





public static PlantGenerator plantGene;
    public void preInit(FMLPreInitializationEvent event) {
	GameRegistry.registerWorldGenerator(plantGene, 0);
}

 

Crash:

Do it like that:

 

// Worldgenerator Registration

GameRegistry.registerWorldGenerator(new WorldGenerator(), 1);

 

and put it in the init or even post-init

That's not the problem, it looks like he's registering it. The problem is you don't assign that PlantGenerator field a value before registering it.

uhm now I got another problem, when i create a new world it takes around 50 times longer and theres a huge hole where i spawn where there are just no blocks at all, and it takes another 5 min to fill that gap, not too sure if thats caused by my epic generator tho..

But Thanks anyway
