Hello!  I am trying to spawn some mobs inside of my TickerClient.  I have spawned entities using items before, but for some reason, I cannot get the mobs to spawn!  At first, I thought it was because I was using WorldClient and not World, but even after switching to World instead of WorldClient, it still didn't work.  Here's the related code:

 

	
private void onTickInGame(Minecraft mc)
{
	mc.theWorld.getGameRules().setOrCreateGameRule("doMobSpawning", "false");


	File allEntityData = new File(mc.getMinecraftDir() + "/mods/TimeMod/past/EntityLocations/" + FMLClientHandler.instance().getServer().getWorldName() + "/" + TimeTraveler.vars.getPastTime() + ".epd");

		try 
		{
			BufferedReader reader = new BufferedReader(new FileReader(allEntityData));
			String line;
			while (((line = reader.readLine()) != null) && nextSet) 
			{
				if(line.equals("===================="))
				{
					nextSet = false;
				}
				else 
				{
					String[] entityData = line.split(",");

					String entityName = entityData[0];
					int entityX = Integer.parseInt(entityData[1]);
					int entityY = Integer.parseInt(entityData[2]);
					int entityZ = Integer.parseInt(entityData[3]);

					//System.out.println(entityName + " " + entityX + " " + entityY + " " + entityZ);
					Entity pastEntity = EntityList.createEntityByName(entityName, mc.thePlayer.worldObj);

					if(pastEntity != null)
					{
						PathEntity path = ((EntityLiving)pastEntity).getNavigator().getPath();
						if(pastEntity != null)
						{
							pastEntity.posX = (double)entityX;
							pastEntity.posY = (double)entityY;
							pastEntity.posZ = (double)entityZ;

							System.out.println(pastEntity);
							mc.thePlayer.worldObj.spawnEntityInWorld(pastEntity);
						}

					}
					else
					{
						EntityPlayerPast pastPlayer = new EntityPlayerPast(mc.thePlayer.worldObj);
						pastPlayer.posX = (double)entityX;
						pastPlayer.posY = (double)entityY;
						pastPlayer.posZ = (double)entityZ;
						System.out.println(pastPlayer);
						mc.thePlayer.worldObj.spawnEntityInWorld(pastPlayer);
					}

			        //path = ((EntityLiving)pastEntity).getNavigator().getPathToXYZ((double)entityX, (double)entityY, (double)entityZ);
			            		
			        //((EntityLiving)pastEntity).getNavigator().setPath(path, 1.0F);
			        //((EntityLiving)pastEntity).getNavigator().tryMoveToXYZ((double)entityX, (double)entityY, (double)entityZ, 0.5F);

				}
				System.out.println(nextSet);
			}
			reader.close();	
		} 
		catch (IOException e) 
		{
			e.printStackTrace();
		} 		
}

You can't spawn mobs on the client.

 

How would I fix this?  I have tried both WorldClient and World to no avail.... do I need a separate ticker for the server?

TickerClient

should be server side

everything you do that NOT ui is server side

always
