Does MC reuse Entity Ids

As for whether it is good to use or not depends on what you want to use it for.  What is it you are trying to do?

At either world gen or birth, I want the baby of my custom mob to store its parents' entity ids. As well, I want the game to check if the id is dead to check if the parents are dead. If MC reuses the ids too often, then the above way will eventually break.

GuiIvVillagerInfo.

GuiIvVillagerInfo does not interact with the UUID. There is a distinct lack of the string "UUID" in that file.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Oops, I meant VillageStructures in the below method:

 

protected void spawnIvVillagers(World worldIn, StructureBoundingBox structurebb, int x, int y, int z, int count, boolean allow_children, int prof)
			{
			    if (this.villagersSpawned < count)
			    {
			        for (int i = this.villagersSpawned; i < count; ++i)
			        {
			            int j = this.getXWithOffset(x + i, z);
			            int k = this.getYWithOffset(y);
			            int l = this.getZWithOffset(x + i, z);
			
			            if (!structurebb.isVecInside(new BlockPos(j, k, l)))
			            {
			                break;
			            }
			
			            ++this.villagersSpawned;
			
			            if (this.isZombieInfested)
			            {
			                EntityZombieVillager entityzombievillager = new EntityZombieVillager(worldIn);
			                entityzombievillager.setLocationAndAngles((double)j + 0.5D, (double)k, (double)l + 0.5D, 0.0F, 0.0F);
			                entityzombievillager.onInitialSpawn(worldIn.getDifficultyForLocation(new BlockPos(entityzombievillager)), (IEntityLivingData)null);
