SecondAmendment

Anyone have a good MCPBot / SRG name tutorial? Like what pre-requisits do I need to use SRG names?

Oh, that makes sense. So what render event should i use for my particular need?

well I found this that i tried private void drawLineWithGL(Vec3d blockA, Vec3d blockB) { GL11.glColor4f(1F, 0F, 1F, 0F); GL11.glBegin(GL11.GL_LINE_STRIP); GL11.glVertex3d(blockA.xCoord, blockA.yCoord, blockA.zCoord); GL11.glVertex3d(blockB.xCoord, blockB.yCoord, blockB.zCoord); GL11.glEnd(); }

How can I draw a line from the player's cursor to a mob on screen? Ive looked around and messed with GL11 but I just cant figure it out. Someone please help.

How to create and change a mobs team? Client side only?

I know how to in spiggot, not sure about forge though.

Ok what about the changing team way? How can i change the mobs team

Does anyone know how to change the color of entity.setGlowing(true). Preferably a way that doesn't involve changing the entity's team.

What would the method be called? I cant seem to find it on the spreadsheet

How do I do it with MC Bot in order to get the SRG name?

Hmmmm... Im having trouble getting the field. the crash report says it cannot find it. What am I doing wrong? public void playerTick(PlayerTickEvent event) throws IllegalArgumentException, IllegalAccessException, NoSuchFieldException, SecurityException { List<Entity> entities = event.player.getEntityWorld().getEntitiesWithinAABBExcludingEntity(event.player, event.player.getEntityBoundingBox().expand(5.0D, 5.0D, 5.0D)); for(Entity entity : entities){ if((entity instanceof EntityMob && ((EntityLivingBase) entity).getHeldItemMainhand() != null && !previousmobs.contains(entity))){ Field dropchance = null; dropchance = ((EntityLiving)entity).getClass().getDeclaredField("inventoryHandsDropChances"); dropchance.setAccessible(true); Object floatchance = dropchance.get(entity); event.player.addChatMessage(((EntityLivingBase) entity).getHeldItemMainhand().getTextComponent().appendSibling((new TextComponentString(" Drop Chance: ").appendText(Array.get(floatchance , 0).toString())))); Crash Report: [11:04:45] [Server thread/ERROR]: Encountered an unexpected exception net.minecraft.util.ReportedException: Ticking player at net.minecraft.network.NetworkSystem.networkTick(NetworkSystem.java:210) ~[NetworkSystem.class:?] at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:806) ~[MinecraftServer.class:?] at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:687) ~[MinecraftServer.class:?] at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:156) ~[IntegratedServer.class:?] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:536) [MinecraftServer.class:?] at java.lang.Thread.run(Unknown Source) [?:1.8.0_65] Caused by: java.lang.RuntimeException: java.lang.NoSuchFieldException: inventoryHandsDropChances at com.google.common.base.Throwables.propagate(Throwables.java:160) ~[guava-17.0.jar:?] at net.minecraftforge.fml.common.eventhandler.EventBus.post(EventBus.java:191) ~[EventBus.class:?] at net.minecraftforge.fml.common.FMLCommonHandler.onPlayerPreTick(FMLCommonHandler.java:360) ~[FMLCommonHandler.class:?] at net.minecraft.entity.player.EntityPlayer.onUpdate(EntityPlayer.java:215) ~[EntityPlayer.class:?] at net.minecraft.entity.player.EntityPlayerMP.onUpdateEntity(EntityPlayerMP.java:341) ~[EntityPlayerMP.class:?] at net.minecraft.network.NetHandlerPlayServer.update(NetHandlerPlayServer.java:174) ~[NetHandlerPlayServer.class:?] at net.minecraftforge.fml.common.network.handshake.NetworkDispatcher$1.update(NetworkDispatcher.java:216) ~[NetworkDispatcher$1.class:?] at net.minecraft.network.NetworkManager.processReceivedPackets(NetworkManager.java:308) ~[NetworkManager.class:?] at net.minecraft.network.NetworkSystem.networkTick(NetworkSystem.java:195) ~[NetworkSystem.class:?] ... 5 more Caused by: java.lang.NoSuchFieldException: inventoryHandsDropChances

Damn it, I hate using Reflection

Is there a way to check the drop chance of an item a mob is holding?

Got it: Solved I dont know how I forgot such a basic rule of java. Whenever iterating through a List always use an Iterator.

Oh yeah. I forgot about the iterator method

public void playerTick(PlayerTickEvent event) { List<Entity> entities = event.player.getEntityWorld().getEntitiesWithinAABBExcludingEntity(event.player, event.player.getEntityBoundingBox().expand(1.0D, 1.0D, 1.0D)); for(Entity entity : entities){ if((entity instanceof EntityMob && ((EntityLivingBase) entity).getHeldItemMainhand() != null && !previousmobs.contains(entity))){ event.player.addChatMessage(((EntityLivingBase) entity).getHeldItemMainhand().getTextComponent()); previousmobs.add((EntityMob) entity); } } if(!previousmobs.isEmpty()){ for(Entity e : previousmobs){ if(e.isDead){ previousmobs.remove(e); } } } ConcurrentModificationException: (I am assuming that means that at the same time it is removing it from the list it is also checking if its on the list causing it to crash) The game crashes right after I kill a mob and the body drops.

Where do I end this discussion? SOLVED

Silly me, how did I make such a mistake. Thank you very much sir.

I know, I still have to add a check for a null getItemMainHand but I already tried commenting that out and the problem still occured on the line where it states: player.getEntityWorld().getEntitiesWithinAABBExcludingEntity(event.player, event.player.getCollisionBoundingBox().expand(5.0D, 5.0D, 5.0D)); as for the entities field not being a local variable I changed it: @SideOnly(Side.CLIENT) @SubscribeEvent public void playerTick(PlayerTickEvent event) { List<Entity> entities = event.player.getEntityWorld().getEntitiesWithinAABBExcludingEntity(event.player, event.player.getCollisionBoundingBox().expand(5.0D, 5.0D, 5.0D)); for(Entity entity : entities){ event.player.addChatMessage(((EntityLivingBase) entity).getHeldItemMainhand().getTextComponent()); } if(event.player.getLastAttacker() != null && !event.player.getLastAttacker().equals(previousentity) && (event.player.getLastAttacker().getHeldItemMainhand() != null)){ event.player.addChatMessage(event.player.getLastAttacker().getHeldItemMainhand().getTextComponent()); previousentity = (Entity) event.player.getLastAttacker(); } } Problem still occurs. Same line I just didn't have the variable locally because I might want to use it for later in some other method.

Could it be due to the fact that act that current point in time there are no mobs around me causing it to crash? Ill try adding a check to see if there are any mobs first.

It tells me there is a null pointer but I dont know where a value would be null.

Ok so I am trying to get the mobs around the player. However I cant do that because the entity is Ticking. I have solved many of these problems in the past, however I dont know how to solve this one. public void playerTick(PlayerTickEvent event) { entities = event.player.getEntityWorld().getEntitiesWithinAABBExcludingEntity(event.player, event.player.getCollisionBoundingBox().expand(5.0D, 5.0D, 5.0D)); for(Entity entity : entities){

I fixed it, Thank you for your assistance

Ok so I changed them to a float to allow for a shorter range of numbers, and also added tollerance. But it will not stop, it will still go on forever. new Timer().schedule( new java.util.TimerTask() { @Override public void run() { float x = (float) Minecraft.getMinecraft().thePlayer.posX; System.out.println(x); boolean atPosition = true; Minecraft.getMinecraft().thePlayer.rotationYaw = Minecraft.getMinecraft().thePlayer.rotationYaw+rotation; Minecraft.getMinecraft().gameSettings.keyBindForward.setKeyBindState(Keyboard.KEY_W, true); while(atPosition){ if(((float)Minecraft.getMinecraft().thePlayer.posX) >= x+1){ Minecraft.getMinecraft().gameSettings.keyBindForward.setKeyBindState(Keyboard.KEY_W, false); Minecraft.getMinecraft().thePlayer.rotationYaw = Minecraft.getMinecraft().thePlayer.rotationYaw+rotation; atPosition = false; } } atPosition = true; } }, 0 );
