Generate Custom Flower like Block

Posted August 12, 20169 yr

I am trying to Generate a flower like block. right now it extends Blockbush. i seem to be having trouble with this line

if (worldIn.isAirBlock(blockpos) && (!worldIn.provider.getHasNoSky() || blockpos.getY() < 255) && this.getBlock.canBlockStay(worldIn, blockpos, this.state))

this part makes my game crash this.getBlock.canBlockStay(worldIn, blockpos, this.state)

I have this and this works fine:

public WorldGenerator BUSH= new WorldGenBush((BlockBush) BlockClass.BLOCK);

@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator, IChunkProvider chunkProvider) {
	switch (world.provider.getDimension()) {
	case -1:
		break;
	case 0:
		runGenerator(BUSH, world, random, chunkX, chunkZ, 7, 50, 120);
		break;
	case 1:
		break;
	}
}

private void runGenerator(WorldGenerator generator, World world, Random random, int chunk_X, int chunk_Z, int chancesToSpawn, int minHeight, int maxHeight){
	if (minHeight < 0 || maxHeight > 256 || minHeight > maxHeight){
		throw new IllegalArgumentException("Illegal Height Arguments for WorldGenerator");
	}
	int heightDiff = maxHeight - minHeight + 1;
	for (int i = 0; i < chancesToSpawn; i++); {
		int x = chunk_X * 16 + random.nextInt(16);
		int y = minHeight  + random.nextInt(heightDiff);
		int z = chunk_Z * 16 + random.nextInt(16);
		generator.generate(world, random, new BlockPos(x, y, z));
	}
}

}

Please actually post your crash-log. Without that, we have no clue what's actually happening.

You never assign a value to IWorldGenTwigs#state, so it is null and Java throws an NPE when it is referenced.

While not the cause of the problem IWorldGenTwigs should be called WorldGenTwigs, as it is a class, not an interface.

Dude, seriously. The first line is the most important one: it tells us/you what the error is. The second line is the second most important: it tells us/you where the error is. We need both.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )
