how do i get things such as my ores and biome to only spawn in my dimension please help

not definite as I've not done any biome or dimension ID stuff myself, but in the biome spawning script(and ore) can you not get it to check the world dimension id (using world.provider.dimensionID) and if it is not equal to your dimensions id return false or stop the script or something (I'm assuming a world parameter is passed somewhere)

 

again i've not got any experience of this but that would be my first guess

nope ive tried that thx anyway though

Since you have your own dimension, could you not just make it spawn trough the world generation for your new world and only there?

have tried but dont know how to get ores to generate in my dimension and biomes not to generate in the overworld

For the ore:

In your generate file add a switch statement of world.provider.dimensionID.

If it is your custom dimension id then add your generate method there.

If you want a certain ore, in your dimension.

 

You need to put the ore in the biome, here is an example.

 

public void generateSurface(World world, int x, int y, int z, Random rand)

BiomeGenBase biome = new BiomeGenBase(); something like that.

YourOre ore = new YourOre();

 

if (biome instanceof BiomeGenBase.YOURBIOME)

{

    //add your generating stuff

    ore.generate(world, x, y, z, rand);

}
