Hi everibody! I am having an issue making a custom arrow.... The problem i have is that when i shot the arrow on a block this doesn't stay in the block but it falls... Here is a video for better explain what is my problem https://www.youtube.com/watch?v=S-luhXMK0zg&feature=youtu.be And here is the code of my custom arrow In the mainMod class EntityRegistry.registerModEntity(EntityRubyArrow.class, "RubyArrow", 1, this, 128, 1, true);

Thank you so much for helped me! I know i'm becoming boring but i have just a final problem, when i shot the arrow this doens't stay in the block, but fall... Here's a video to better explain what i'm saying https://www.youtube.com/watch?v=S-luhXMK0zg&feature=youtu.be

I think it's all ok in the ClientProxy too but maybe i must change something [EDIT] I've moved the proxy.registerRenderThings() from preInit to Init and it worked! Now, for what reguarding the FOV Zoom, how can i added it to my custom bow without editing the original code? I know that simply extending the ItemBow has no effect because in the original code it is written that only if the item is the Bow (and not an instance of ItemBow) there is the zoom

Yes, it's the same problem, i can't render properly my custom bow

How can i do that? I've never used this events and also i don't know where to find a guide for this

Hi everybody! I'm asking you help making a miner helmet. This item is an helmet that while is weared give night vision to the player, but i want to hide the particles effect and the guy which says that the nighty vision effect is applied for **:**. I'm posting a screen to better explain what i'm trying to do. I've tried to copy the code directly from the potion effect (the part where it says to minecraft "add light ecc..." but it seems is hard-coded because it's not in the Potion files Image: https://www.dropbox.com/s/h1yroci3ioksjd7/2014-03-11_18.58.58.png This is the code of the helmet package mod_ores.items; import net.minecraft.client.renderer.texture.IconRegister; import net.minecraft.entity.Entity; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.EnumArmorMaterial; import net.minecraft.item.ItemArmor; import net.minecraft.item.ItemStack; import net.minecraft.potion.Potion; import net.minecraft.potion.PotionEffect; import net.minecraft.world.World; public class ItemMinerHemet extends ItemArmor { private String mat; private String name; public ItemMinerHemet(int par1, EnumArmorMaterial par2EnumArmorMaterial, int par3, int par4, String par5, String par6) { super(par1, par2EnumArmorMaterial, par3, par4); mat = par5; name = par6; } public void registerIcons(IconRegister par1IconRegister) { itemIcon = par1IconRegister.registerIcon(mod_ores.main.modId + ":" + name); } public String getArmorTexture(ItemStack stack, Entity entity, int slot, int layer){ if (layer == 2) return mod_ores.main.modId + ":" + "textures/models/armor/" + mat + "_2.png"; else return mod_ores.main.modId + ":" + "textures/models/armor/" + mat + "_1.png"; } @Override public void onArmorTickUpdate(World world, EntityPlayer player, ItemStack itemStack) { ItemStack head = player.getCurrentItemOrArmor(4); if(player.getCurrentItemOrArmor(4) != null){ if(head.getItem() == mod_ores.main.minerHelmet){ player.addPotionEffect((new PotionEffect(Potion.nightVision.getId(), 10, 0))); } } } } Thanks for helping me!

It has no effect

Alright! Almost done I've added this two lines in my main mod class EntityRegistry.registerGlobalEntityID(EntityRubyArrow.class, "rubyArrow", EntityRegistry.findGlobalUniqueEntityId()); EntityRegistry.registerModEntity(EntityRubyArrow.class, "rubyArrow", 1, this, 128, 1, true); the registerModentity has different values from yours because the arrows rotate while shooting, so i've changed the last 3 values and now goes good. The only two things left are: The collisions The FOV Zoom When i shoot the arrow and this hit a block, sometimes it won't go in the block, but if fell. I noticed that is only a rendering thing, because when i'm trying to take back the arrow, it only does when it hit, not where it actually is. Also there is no FOV Zoom while using the bow, and i don't know how to make this without modifiyng the EntityPlayer class, wich do this for the normal bow. Here's a video i've recorded to explain better, i'm sorry for my bad english but i'm italian http://www.youtube.com/watch?v=UzvjCTkJsVc&feature=youtu.be The animation while loading is not in the video but it's not a problem, i've already solved it

So there is not the problem to make the mistake to give same id to different blocks? The game itself assigns an automatic id to the blocks? Edit: cool, the Ore Ruby has already a translated name in the game O_O I'm italian, i didn't added a translation method yet, but i see the ore name in italian, not tile.oreRuby.name but "Rubino Grezzo", "Ruby Ore" in english. Lol. Also it seems like i've supposed, the game itself give an unique id to the blocks, wich is really cool. Thanks for help me, i'll close this post

I know, but i've tried to make it in the init function because it doesn't work in pre init method, i've already a 1.6.4 version of the mod, i know where all things go but it seems that is wrong in 1.7 EDIT: I've changed it again right now and it worked O_O and so yes, i'm a stupid (doh!). Aniway, why the id of this block is 165 and not 1000 like i specify?

Hi everybody! I have a simple question for you I'm trying to update my mod to 1.7.2 but i can't even add a simple block! D: I'm trying to add a new ore but it seems that the code doesn't work, in fact in game there isn't my block.

Yes sorry i've looked for it and i'm looking all the list of packets --EDIT: it seems there is no packet who write on a block, only the Packet130UpdateSigns it does, so i have created a CustomNetHandler and a CustomPacket equal to the Packet 130 but it has no effects.... maybe i'm missing something?

Yes sorry i've looked for it and i'm looking all the list of packets

Packet250CustomData doesn't exist

Ok, so i've tried to make a TileEntity like signs but not editable. But the text doesn't appear on block because i can't find a packet who do that: package net.minecraft.tileentity; import cpw.mods.fml.relauncher.Side; import cpw.mods.fml.relauncher.SideOnly; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.network.packet.Packet; import net.minecraft.network.packet.Packet130UpdateSign; public class TileEntitySign extends TileEntity { /** An array of four strings storing the lines of text on the sign. */ public String[] signText = new String[] {"TEST", "TEST", "TEST", "TEST"}; /** * The index of the line currently being edited.

So how can i print messages directly on the blocks?

I can also do it, but if you see i have differents chat messages based on the results and the level of the block. The block has 3 power level, if he find no blocks, it will show a message, if he find a block, i will show "I found something", if is level 1, "I found 10 block", if is level 2, "I found 10 blocks and one of them is at x..." if is level 3.... A button who send a message will send the same message i guess --Edit: alternatively how can i print messages directly on the block? For example, if he found no blocks, it will appear an X on the block, so the player is no more necessary

I want this: (1)Peter place the BlockDetector and make a circuit (2)James push the button (3)A chat message appeare to James, not to Peter. The player who push the button will have a chat message, not the one who placed it.

mmm... it's strange because basically it's the same system that uses command blocks. Infact if i, player, activate a command block, a chat message in MY chat appear, not in the other player's chat. So i know thath there must be a way to do this, but i can't figure how to do that.... In the command class to send a chat message it uses a ChatMessageComponent, which is simple to create, and a ICommandSender, wich i don't know how to instantiate...

Ok, but i want to send a chat message only to one player, the one who activate the block. For example, the block is connected to a lever or to a redstone circuit and in the world there are 2 or more players. I want to send a chat message only at the player who activate the lever or the circuit, so my question is: how can i understand wich player activate the circuit and send him a message?

Is what i've dobe first, basically i've copied the redstone lamp class. The problems are the chat messages because i can make a custom function like the onBlockActivated wirhout EntityPlayer parameter and it works fine. But i want to add a chat message when the block has an input, like when you run a command... I've already see the command block class but it wasn't help....

Hi guys, i want to ask you a little help with my mod. I have a block that when clicked by a player it searches for an ore and gives a chat message. Now i want to make it activable by redstone but i don't know how to say "if the redstone is on then activate the block" because the onNeighborBlockChange has no EntityPlayer parameter. And if i use the Minecraft.getMinecraft().thePlayer, on lan it gives the chat messages only at who started the lan (only when the block is activated by redstone), the server doesn't even start!
