I used the EntityLiving for tessellator, but if it crashes... EDIT: I have no idea on how to do that, I tried with this.renderItem(); method but it crashes when I equip it! How can I do that? I don't understand at all the code you gave to me

Hi guys I'm lorizz and I need to know why my IItemRenderer class, that is used for a class EXTENDING TO A SWORD, doesn't render my texture in case of EQUIPPED and EQUIPPED_FIRST_PERSON, if I don't use those it renders the texture normally but I need to move the model, so this is why I use IItemRenderer (I use it for another reason that you will may find in my code)! This is the IItemRenderer class: package it.exoworld_client.renderer; import it.exoworld_client.ExoWorld_Client; import it.exoworld_client.extender.ItemDaggerExtender; import it.exoworld_client.registry.ItemRegistry; import it.exoworld_client.watcher.PlayerInformation; import net.minecraft.client.Minecraft; import net.minecraft.client.renderer.ItemRenderer; import net.minecraft.client.renderer.Tessellator; import net.minecraft.client.renderer.entity.RenderItem; import net.minecraft.entity.EntityLiving; import net.minecraft.item.ItemStack; import net.minecraft.util.Icon; import net.minecraftforge.client.IItemRenderer; import org.lwjgl.opengl.GL11; import org.lwjgl.opengl.GL12; import cpw.mods.fml.client.FMLClientHandler; public class ItemDaggerRenderer implements IItemRenderer { private static RenderItem renderItem = new RenderItem(); private Minecraft mc; @Override public boolean handleRenderType(ItemStack item, ItemRenderType type) { // TODO Auto-generated method stub return type == ItemRenderType.INVENTORY || type == ItemRenderType.EQUIPPED || type == ItemRenderType.EQUIPPED_FIRST_PERSON; } @Override public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item, ItemRendererHelper helper) { // TODO Auto-generated method stub return false; } @Override public void renderItem(ItemRenderType type, ItemStack item, Object... data) { EntityLiving entity = (EntityLiving) data[1]; ItemRenderer itemRenderer = this.mc.entityRenderer.itemRenderer; PlayerInformation props = PlayerInformation.get(Minecraft .getMinecraft().thePlayer); ItemDaggerExtender dagger = (ItemDaggerExtender) item.getItem(); int selectedClass = props.getSelectedClass(); int classConfirm = props.getClassConfirm(); Icon daggerIcon = dagger.getIconIndex(item); Icon daggerWrongClass = ItemRegistry.daggerWrongClass .getIconIndex(item); if (type == ItemRenderType.INVENTORY) { if (classConfirm != 1 && selectedClass != 1) { this.renderItem.renderIcon(0, 0, daggerWrongClass, 16, 16); } else { this.renderItem.renderIcon(0, 0, daggerIcon, 16, 16); } } GL11.glPushMatrix(); FMLClientHandler.instance().getClient().renderEngine .bindTexture("/mods/" + ExoWorld_Client.modid + "/textures/items/dagger/" + dagger.getUnlocalizedName().substring(5) + ".png"); if(type == ItemRenderType.EQUIPPED) { } else if (type == ItemRenderType.EQUIPPED_FIRST_PERSON) { } GL11.glPopMatrix(); } } I tried using "Minecraft.getMinecraft().renderEngine.bindTexture()" method but still not working, also I tried using tessellator...crash because of "EntityLiving entity = (EntityLiving) data[1];" and I don't know why, it tells me "ArrayIndexOutOfBounds". Who can help me? Maybe it doesn't work because it's used for a class that extends to a custom extender that extends to an ItemSword? Does my extender need to extends to an Item? I can make my own ItemSword if I need so. Thanks! (I'm italian sorry for my bad english...if I made some grammar mistakes)

1)yes 2)yes Edit: SOLVED! I didn't register the event in clientside too, only serverside! Thanks anyway!

How can I fix it? if(this.mc.thePlayer != null) didn't work

Hi guys, today I learned about DW, I create a class that implements IExtendedEntityProperties and registered my DW. After registering those in EntityConstructing event, they worked perfectly! Load and save are perfect! But the problem is there...... The RenderGameOverlay, it crashes I think because of this cast PlayerInformation props = PlayerInformation.get((EntityPlayer) this.mc.thePlayer); There's always a problem with Player cast D: Here's my PlayerInformation that implements IExtendedEntityProperties: Where it loads in EntityConstructing event: Where it crashes in RenderGameOverlay event: That's the crash log, it's a NullPointer: Please help me, I need to release my mod next two months!

Huh...no, quite the opposite actually. By the way, gui is client side only, so you don't need to check. Done, but now it shows me this error with my new code: METHOD: public static void sendPacket(EntityPlayer entityPlayer) { EntityClientPlayerMP player = (EntityClientPlayerMP) entityPlayer; ByteArrayOutputStream byteOutputStream = new ByteArrayOutputStream(); DataOutputStream dataOutputStream = new DataOutputStream( byteOutputStream); try { dataOutputStream.writeInt(player.entityId);// this info is unused // when handling the // packet ?? } catch (Exception e) { e.printStackTrace(); } Packet250CustomPayload packet = new Packet250CustomPayload( ECPacketHandler.GCHATSYNC, byteOutputStream.toByteArray()); FMLClientHandler.instance().sendPacket(packet); } ERROR: Caused by: java.lang.RuntimeException: Attempted to load class mods/enetchat/client/gui/EGuiChatGeneral for invalid side SERVER at cpw.mods.fml.common.asm.transformers.SideTransformer.transform(SideTransformer.java:50) at cpw.mods.fml.relauncher.RelaunchClassLoader.runTransformers(RelaunchClassLoader.java:352) at cpw.mods.fml.relauncher.RelaunchClassLoader.findClass(RelaunchClassLoader.java:225) ... 18 more

If you use a MySQL Api it would be very very easy... Use someting like JDBC (Java DataBase Connection)

Why are you creating a Hardcore Mod while there is already one made by Minecraft?... People's brain Anyway make a command like /stopmod or /modstop that when it's done it will close the server, on the server close (so with the FMLOnServerStoppingEvent) save everything you need to be saved. If you can't stop the server check in the MinecraftServer package

Hey guys, I need help with my own custom chat. I created a chat that implements group system (made by me) and a general one, that is used like as the normal, the problem is the packet handling! I cannot cast EntityClientPlayerMP with EntityPlayerMP and I know that so I'm here to ask you how to do this! I want that when a player write something in the custom chat, it will be showed for every player in the server.

*pretend i didnt see anything.............* in your frirst post you talk about registerng with the server yet your tickhabdler return a tick type of client and render, 2 type which dont exists server side. you want this tick handler server side or client side ? Bold word are just wtf? Anyway Server side

Nooooo you don't say? : I just wrote it... still not work

Hi guys, I wanted to make a special armour that it charge and then ask you to press F for release the Fury Mode. I created it in my ItemClass, it worked good but the problem is, the server is not registering this. So I asked to my friend that can make mod and said to me: "You need to register a new TickHandler for this thing" but the problem is, I can't figure out I tried doing this: TickHandler class: package mods.exoworld.handler; import java.util.EnumSet; import mods.exoworld.Main; import mods.exoworld.item.ExoTNTHelmet; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.ItemStack; import net.minecraft.world.World; import cpw.mods.fml.common.ITickHandler; import cpw.mods.fml.common.TickType; public class ExoServerTickHandler implements ITickHandler { public ExoTNTHelmet event; public World world; public EntityPlayer player; @Override public void tickStart(EnumSet<TickType> type, Object... tickData) { // TODO Auto-generated method stub } public void onTickArmor(EntityPlayer player, World world, ItemStack itemStack, ExoTNTHelmet event) { ItemStack helmet = player.inventory.armorItemInSlot(3); ItemStack chestplate = player.inventory.armorItemInSlot(2); ItemStack leggings = player.inventory.armorItemInSlot(1); ItemStack boots = player.inventory.armorItemInSlot(0); if (helmet.itemID == Main.ExoTNTHelmet.itemID && chestplate.itemID == Main.ExoTNTChestplate.itemID && leggings.itemID == Main.ExoTNTLeggings.itemID && boots.itemID == Main.ExoTNTBoots.itemID) { event.counter += 0.021F; System.out.println(event.counter); if(event.counter > 50F) { event.powerupIsAvailable = true; } if (event.powerupIsAvailable == true) { event.counter -= 5F; if (event.counter < 0F) { event.counter = 0F; } } } } public void onPowerupActivated() { while (event.counter < 0F) { // I want that every 5 ticks the function do this code below if (event.powerupIsAvailable == true) world.createExplosion(null, player.posX + 5, player.posY, player.posZ, 5.0F, false); world.createExplosion(null, player.posX - 5, player.posY, player.posZ, 5.0F, false); world.createExplosion(null, player.posX, player.posY, player.posZ + 5, 5.0F, false); world.createExplosion(null, player.posX, player.posY, player.posZ - 5, 5.0F, false); event.powerupIsAvailable = false; } } @Override public void tickEnd(EnumSet<TickType> type, Object... tickData) { // TODO Auto-generated method stub } @Override public EnumSet<TickType> ticks() { // TODO Auto-generated method stub return EnumSet.of(TickType.CLIENT, TickType.RENDER); } @Override public String getLabel() { // TODO Auto-generated method stub return null; } } My KeyHandler code: package mods.exoworld.handler; import java.util.EnumSet; import mods.exoworld.item.ExoTNTHelmet; import net.minecraft.client.settings.KeyBinding; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.world.World; import org.lwjgl.input.Keyboard; import cpw.mods.fml.client.FMLClientHandler; import cpw.mods.fml.client.registry.KeyBindingRegistry.KeyHandler; import cpw.mods.fml.common.TickType; public class ExoKeyHandler extends KeyHandler { public ExoServerTickHandler tickHandler; public static KeyBinding armorPowerup = new KeyBinding( "Armor Powerup", Keyboard.KEY_F); public static KeyBinding[] arrayOfKeys = new KeyBinding[] { armorPowerup }; public static boolean[] areRepeating = new boolean[] { false }; public ExoKeyHandler() { super(arrayOfKeys, areRepeating); } @Override public String getLabel() { return "ExoWorld's KeyHandler"; } @Override public void keyDown(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd, boolean isRepeat) { if (tickEnd) { if (kb.keyCode == armorPowerup.keyCode) { tickHandler.onPowerupActivated(); } } } @Override public void keyUp(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd) { } @Override public EnumSet<TickType> ticks() { return EnumSet.of(TickType.CLIENT); } } P.S.: Never used TickHandler in my life, no tutorials, no examples = never use this sh@t again

Oh my god thanks! It worked

I know what SideOnly means -.- I just put that in onItemRightClick for mistake, now it works on server PERFECTLY How???

Guys I have a mod that add something specials for my server, it's the RageMode, whenever the player do the right click after a combo of 80 hits, it will start the rage mode BUT: I want that the rage mode ends after 7.2 seconds! I tried making a TickHandler but I can't figure out how to do that, I never did something with ticks, if you can help me and the code works I'll finally know how to do ticks :3 My ExoRageModeEvent code: public class ExoRageModeEvent extends ItemSword { public static int comboStreak = 0; public static int maxComboStreak = 240; public static int minComboStreak = 3; public static boolean rageMode = false; public static boolean soundStarted = false; public ExoRageModeEvent(int par1, EnumToolMaterial par2EnumToolMaterial) { super(par1, par2EnumToolMaterial); // TODO Auto-generated constructor stub } @SideOnly(Side.CLIENT) public void onUpdate(ItemStack item, World world, Entity entity, int par4, boolean par5) { if (par5 && (entity instanceof EntityPlayer)) { if (rageMode == false) { EntityPlayer player = (EntityPlayer) entity; } else { EntityPlayer player = (EntityPlayer) entity; /* * wait 7.2 seconds; rageMode = false; */ } } else { EntityPlayer player = (EntityPlayer) entity; player.capabilities.setPlayerWalkSpeed(0.1F); rageMode = false; comboStreak = 0; } } public boolean hitEntity(ItemStack par1ItemStack, EntityLiving par2EntityLiving, EntityLiving par3EntityLiving) { par2EntityLiving.setPosition(par2EntityLiving.posX, par2EntityLiving.posY, par2EntityLiving.posZ); comboStreak += 1; if (par3EntityLiving instanceof EntityPlayer) { if (comboStreak == 80) { EntityPlayer player = (EntityPlayer) par3EntityLiving; player.sendChatToPlayer("Your powerup is ready! Right click to activate it!"); } } if (comboStreak > maxComboStreak) { comboStreak = 240; } return true; } @SideOnly(Side.CLIENT) public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer) { if (comboStreak >= 80) { rageMode = true; // Wait 0.05 seconds because if I put in the condition "soundStarted == false" // it will automatically read first the soundStarted = true under that "playSoundEffect" // because the song will load 0.01 second after! par2World.playSoundEffect(par3EntityPlayer.posX, par3EntityPlayer.posY, par3EntityPlayer.posZ, "ExoWorld.RageMode", 1.0F, 1.0F); soundStarted = true; } if (comboStreak >= 90) { comboStreak = 0; } return par1ItemStack; } } Any help? Thanks!

Hey guys, I'm making a Mirror's Edge mod (called Mirror's Craft) I need to do the Wallrun function D: Making the animation I'll think after all, but now I need the function to detect the player colliding a block, how can I do this?? I searched everywhere, but no results

So vogner, how can I do that?

Have you created the basic mod class?

Just put simply this this.iconIndex = iconRegister.registerIcon("NameOfYourModFolder:NameOfYourItem/Block"); example this.iconIndex = iconRegister.registerIcon("mod:superpickaxe"); .-.
