Anyone..?

I'm trying to make a new WorldType that generates my custom biomes only, with alternative ores instead of the Vanilla ones. But for some reason it's only generating one biome and the Vanilla Rivers. And on top of that the Wasteland is generating too many trees and NOT generating the alternative ores. Anyone know what's causing this?

I want to use symbols in some items' tooltips to represent the elements and special effects of weapons I'm adding but they appear significantly smaller than they do in out-of-Minecraft text. All extra symbols (stars, hearts, music notes, etc) appear in a significantly smaller font size and are slightly superscript in tooltips. Even when running Minecraft on a large TV I have trouble seeing what the symbols are. For example, I want the enchantability of items to be displayed with a star next to them (like "☆10" on a Diamond Sword). However, what shows up is more like "☆10". This is what I'm using (in the ItemTooltipEvent so I can add to Vanilla items): event.toolTip.add(EnumChatFormatting.BLUE + "☆ " + item.getItemEnchantability()); Is there any way to fix this?

Here's the full code: http://pastebin.com/zetGiejq

Okay, so how would I save it in that? I tried setting NBTTagCompound entityData = player.getEntityData(); to NBTTagCompound entityData = player.getEntityData().getCompoundTag(EntityPlayer.PERSISTED_NBT_TAG); And it just gives the player items on every single login now. I have no idea how to actually use that.

I'm trying to give the player items the first time they join the world. So I check a boolean in the player nbt, if it's false I check if their username contains one of several specific words and if it does it gives them some special items and enables some other aesthetic features, then set it to true. And at first glance it works perfectly. I log in to a new world, get the items, log out and when I log back it it recognises that I already got them. Unfortunately, if I log out after I die it's undone and it gives me new items the next time I log back in. I assume this is because the player gets a new nbt on respawn? I'm specifically trying to do this WITHOUT using IExtendedEntityProperties because I cannot get that to work no matter which tutorial I try, for what ever reason. How can I get it to stay through death without using IEEP? @SubscribeEvent public void login(PlayerLoggedInEvent event) { EntityPlayer player = event.player; NBTTagCompound entityData = player.getEntityData(); if (event.player.dimension == 0) { if (entityData.getBoolean(Infinity.MODID + "." + "RecievedItems") == false) { if (Tools.hasRelatedName(player)) { player.inventory.addItemStackToInventory(new ItemStack(Content.dream_sword)); player.addChatMessage( new ChatComponentText(EnumChatFormatting.GOLD + "You got a Keychain and the Dream Sword!")); player.inventory.addItemStackToInventory(new ItemStack(Content.keychain)); entityData.setBoolean(Infinity.MODID + "." + "RecievedItems", true); } else { player.addChatMessage(new ChatComponentText(EnumChatFormatting.LIGHT_PURPLE + "[" + Infinity.NAME + "]" + EnumChatFormatting.RESET + "There's nothing special for you today.")); } } } }

I'm trying to do it that way because it's shorter and I don't have to edit the shaped recipe object every single time. And the recipes are being registered AFTER all the content is. All the content shows up in-game, so none of it is null.

I'm trying to use pre-built Object arrays that take items as parameters so I don't have to copy/paste/edit every single shaped recipe since they're all the same shape, just with a different main material. But for some reason I'm getting a NullPointerException crash in when loading the mod. I can't figure out what I'm doing wrong. How I'm trying to register them: public static void init() { add(Content.kingdom_key, keyRecipe(Content.heart)); } add() method: public static void add(Item output, Object[] recipe) { GameRegistry.addShapedRecipe(new ItemStack(output), recipe); } keyRecipe() method: public static Object[] keyRecipe(Object synth) { return new Object[] { "AAA", "ABA", "AAA", 'A', synth, 'B', Content.wooden_key }; }

That's my point, I can't figure out how to do that...

I have no idea why, but I can't get any of the many projectile tutorials I've tried to work. It would always either only ever go in one direction or spawn but not move at all until hit. So I gave up and de-obfuscated a mod to try to figure out just what I'm doing so wrongly compared to a finished mod that I've tried and that works, and finally found some code that's successful...at first. Unfortunately, after about 2 seconds of travelling, the projectile starts slowing down exponentially for another second until it stops in mid-air... I assume it's something to do with the math, but I've always been horrible at that so I really don't know what's going on there. What exactly is going on here and how can I get it to just fly straight? Vec3 vec1 = player.getLook(1); EntityLargeFireball fireball = new EntityLargeFireball(player.worldObj); fireball.setLocationAndAngles(player.posX + vec1.xCoord, player.posY + player.getEyeHeight() * 0.85, player.posZ + vec1.zCoord, player.rotationYaw, player.rotationPitch); fireball.motionX = (-MathHelper.sin(fireball.rotationYaw / 180.0F * 3.141593F) * MathHelper.cos(fireball.rotationPitch / 180.0F * 3.141593F)); fireball.motionZ = (MathHelper.cos(fireball.rotationYaw / 180.0F * 3.141593F) * MathHelper.cos(fireball.rotationPitch / 180.0F * 3.141593F)); fireball.motionY = (-MathHelper.sin(fireball.rotationPitch / 180.0F * 3.141593F)); fireball.motionX *= 2.0D; fireball.motionY *= 2.0D; fireball.motionZ *= 2.0D;

I have an item that's supposed to basically search the player's hotbar for a specific weapon type, check if it's damaged and repair it if it is.

If the player is holding a magic rod when a key is pressed it should cast a fireball and damage the rod. But I'm not sure how to go about doing that. I'm assuming the code I have won't work (I haven't made the projectile or packets yet so I haven't tested it) since it's getting the equipped item of the client player? If not, how do I get the regular EntityPlayer from that in a packet? Would simply passing the client player through the packet parameters and casting it to EntityPlayer be enough? @SubscribeEvent public void onKeyPress(KeyInputEvent event) { if (Keybinds.fire.isPressed()) { ItemStack stack = Minecraft.getMinecraft().thePlayer.getCurrentEquippedItem(); if (stack.getItem() instanceof Rod) { if (stack.getItemDamage() < stack.getMaxDamage() - 1) { // TODO packet stack.damageItem(1, Minecraft.getMinecraft().thePlayer); } } } }
