WorldType GuiTroubles

[Niightlord491]

Hey everybody I got a simple problem I think... But anyways the problem is that I made a new WorldType and I wish for when the player first spawns in this worldtype my GUI screen will appear. Now I've heard that forge has an amazing method just for this purpose called onGuiWorldPress and I'm looking forward to using it but I just don't know where to inject it into my code. Heres the code please help!

package net.minecraft.src;

public class SinCityWorldType extends WorldType {
public SinCityWorldType() {
        super(2, "Sin City");
        // The first parameter is the id number of the WorldType,
        // vanilla Minecraft uses 0, 1, and 8 already. The max that can be used is 15,
        // The second parameter is our textname for our WorldType, the case needs to
        // match the "generator.void" localization in the "mod_" file.
}

public WorldChunkManager getChunkManager(World world) {
        return new SinCityChunkManager(world);
        // This is our ChunkManager class, it controls rain, temp, biomes, and spawn location
}


public boolean hasVoidParticles(boolean flag) {
        return false; // Used to determine if there is a sky
}

public int getSeaLevel(World world) {
        return 0; // Sets the Sea Level, be careful with this one, it controls the Y value of your spawn point.
}

public double voidFadeMagnitude() {
        return 0.0D; // Sets the void fade, play with it to see which values work for you.
}
public IChunkProvider getChunkGenerator(World world)
{
return new ChunkProviderFlat(world, world.getSeed(), world.getWorldInfo().isMapFeaturesEnabled());
// Change the provider on the line above to the Chunk Provider of choice.
}
}

 

Also here's the GUI if you need it.
