Ah, that'd explain it. Thanks!

Hi all, I'm attempting to create a block that during the day, has a fairly dull texture, but at night changes to an animated texture, lights up and produces particles. So far I've managed to get a single instance of the block to match this behaviour perfectly via metadata, but I can only get to work on one instance. If multiple instances are present, it seems that only one is chosen (seemingly randomly) for an update. I've added the relevant classes below, anyone have any idea how I can get all instances of these blocks to update correctly? Here's the block class import java.util.Random; import net.minecraft.block.material.Material; import net.minecraft.client.Minecraft; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.util.IIcon; import net.minecraft.world.IBlockAccess; import net.minecraft.world.World; import uk.co.thisishillman.particles.EntityFXColoredDust; import cpw.mods.fml.common.registry.GameRegistry; import cpw.mods.fml.relauncher.Side; import cpw.mods.fml.relauncher.SideOnly; public class BlockMetalPrecious extends CustomBlock { private static String[] names; private boolean isNight; public BlockMetalPrecious(Material mat, String unlocalizedName, String... subNames) { super(mat, unlocalizedName, subNames); this.names = subNames; //this.setTickRandomly(true); } @Override public void registerRecipe() { //TODO } @Override public Item getItemDropped(int meta, Random rand, int fortune) { return Item.getItemFromBlock(this); } @Override public void randomDisplayTick(World world, int x, int y, int z, Random rand) { boolean previousState = isNight; int meta = world.getBlockMetadata(x, y, z); long worldTime = world.getWorldTime(); if( (worldTime > 13000) && (worldTime < 23000) ) { isNight = true; } else { isNight = false; } if(previousState != isNight) { if(meta == 2 || meta == 3) { if(!previousState && isNight) { world.setBlock(x, y, z, this, 3, 2); } else if(previousState && !isNight) { world.setBlock(x, y, z, this, 2, 2); } world.notifyBlockChange(x, y, z, this); System.out.println("Updated block at: " + x + ", " + y + ", " + z); //world.markBlockForUpdate(x, y, z); } } if(isNight && meta == 3 && rand.nextInt(10) <= 2) { spawnParticle(world, x, y, z); } } private void spawnParticle(World world, int x, int y, int z) { Random random = world.rand; for(int side = 0; side < 6; ++side) { double d1 = (double) ((float) x + random.nextFloat()); double d2 = (double) ((float) y + random.nextFloat()); double d3 = (double) ((float) z + random.nextFloat()); if(side == 0 && !world.getBlock(x, y + 1, z).isOpaqueCube()) { d2 = (double) (y + 1) + 0.0625; } if(side == 1 && !world.getBlock(x, y - 1, z).isOpaqueCube()) { d2 = (double) (y + 0) - 0.0625; } if(side == 2 && !world.getBlock(x, y, z + 1).isOpaqueCube()) { d3 = (double) (z + 1) + 0.0625; } if(side == 3 && !world.getBlock(x, y, z - 1).isOpaqueCube()) { d3 = (double) (z + 0) - 0.0625; } if(side == 4 && !world.getBlock(x + 1, y, z).isOpaqueCube()) { d1 = (double) (x + 1) + 0.0625; } if(side == 5 && !world.getBlock(x - 1, y, z).isOpaqueCube()) { d1 = (double) (x + 0) - 0.0625; } if(d1 < (double)x || d1 > (double)(x + 1) || d2 < 0.0 || d2 > (double)(y + 1) || d3 < (double)z || d3 > (double)(z + 1)) { EntityFXColoredDust dust = new EntityFXColoredDust(world, d1, d2, d3, 0.0f, 0.0f, 0.0f); dust.setColor(97f/255f, 1f, 227f/255f); Minecraft.getMinecraft().effectRenderer.addEffect(dust); } } } @Override public void updateTick(World world, int x, int y, int z, Random rand) { randomDisplayTick(world, x, y, z, new Random()); world.scheduleBlockUpdate(x, y, z, this, 20); } @Override public int getLightValue(IBlockAccess access, int x, int y, int z) { int meta = access.getBlockMetadata(x, y, z); if(meta == 3) return 15; return super.getLightValue(access, x, y, z); } @Override @SideOnly(Side.CLIENT) public void registerBlock() { GameRegistry.registerBlock(this, ItemBlockMetalPrecious.class, super.getUnlocalizedName()); } @Override @SideOnly(Side.CLIENT) public IIcon getIcon(int side, int meta) { return super.getIcon(side, meta); } } //End of class.

I'm trying to implement a generic Flocking AI that I can use for any new creatures I add to my mod in the future. I've followed the flocking information found here (http://bit.ly/1kOI2ul) and implemented it with the code below. However, my creatures don't move at all (except for occasionally falling through the floor). Anyone have any idea where I'm going wrong? If anyone's got any posts/tutorials on group-movement of creatures, that'd be handy too FlockUtils.java FlockAI.java

Awesome, that totally worked. Thanks!

Hey all, I've looked at the tutorials/posts about generating veins of custom blocks/ores in the world but I can't seem to get mine to appear at all. My code's below... what have I missed? My ore generation class... public class MineralGenerator implements IWorldGenerator { @Override public void generate(Random rand, int chunkX, int chunkZ, World world, IChunkProvider chunkGen, IChunkProvider chunkProv) { if(world.provider.dimensionId == 0) { FMLLog.log(Level.SEVERE, "GENERATING CUSTOM ORES!"); generateSurface(rand, chunkX, chunkZ, world, BlockStore.citrineUnref.blockID, 15, 6); generateSurface(rand, chunkX, chunkZ, world, BlockStore.peridotUnref.blockID, 15, 6); generateSurface(rand, chunkX, chunkZ, world, BlockStore.jasperUnref.blockID, 15, 6); generateSurface(rand, chunkX, chunkZ, world, BlockStore.aquamarineUnref.blockID, 15, 6); generateSurface(rand, chunkX, chunkZ, world, BlockStore.moonstoneUnref.blockID, 15, 6); } } private void generateSurface(Random rand, int chunkX, int chunkZ, World world, int blockID, int noVeins, int veinSize) { for(int i = 0; i < noVeins; i++) { int randPosX = chunkX + rand.nextInt(16); int randPosY = rand.nextInt(64); int randPosZ = chunkZ + rand.nextInt(16); new WorldGenMinable(blockID, veinSize).generate(world, rand, randPosX, randPosY, randPosZ); } } } Within my mod's main class... @EventHandler public void load(FMLInitializationEvent event) { commonProxy.registerRenderers(); TabStore.registerTabs(); BlockStore.registerBlocks(); ItemStore.registerItems(); BlockStore.setupRecipes(); ItemStore.setupRecipes(); GameRegistry.registerWorldGenerator(new MineralGenerator()); }

Surely that'll create a recipe that outputs 3 item X's for every input 1 item Y? I'm aiming for the reverse, i.e. outputs 1 item X for every 3 item Y's input. I had thought the code in my original post should do that, but it's only using up 1 input item, not 3.

Hi all, I'm trying to create a recipe for an item I've made that *should* require a stack of 3 input items (i.e. three X's create one Y). The code I'm using at the moment is below, but when creating the output item, only one of the stacked input is used up, not all three. What have I missed? GameRegistry.addShapelessRecipe(new ItemStack(ItemStore.itemY), new ItemStack(ItemStore.itemX, 3));

Awesome, thanks for the info. So if I create a custom block that extends BlockFlowerPot (lets call it VaseBlock for now), and edit the getPlantForMeta() and getMetaForPlant() methods to return the ItemStack/blockID of my new flower respectively, will I then be able to place my flower within the VaseBlock?

So I've created a new block type (that extends from BlockFlower) that uses a differing texture & some different logic on where it can be placed, but for the life of me I can't work out how to get it to sit in a flower pot nicely. Looking at the BlockFlowerPot code, it appears that it explicitly returns the metadata for each vanilla flower/sapling. If I can't edit the original vanilla code, do I have to create my own flower pot to hold my new flower? If so, how does one go about doing it? FYI, I'm pretty good with Java but new to the Minecraft code-base; I've seen mention that flowers need TileEntitys, anyone care to explain the purpose of these to a noobie modder? Thanks
