[1.7.10] Making a mob

[untamemadman]

Can anyone give me a link to a tutorial to how to make a mob in minecraft 1.7.10 because I can't find one

[Eternaldoom]

Just browse my github repo: https://github.com/Eternaldoom/Realms-of-Chaos. You can use Techne to generate models.

I have a tutorial on custom entities.  In this case they are creatures, not mobs, but most of the information is the same.  If your entity is truly custom (like custom model, AI, sounds, etc.) then there are actually quite a few steps you need to do and my tutorial should help you with many of them: http://jabelarminecraft.blogspot.com/p/creating-custom-entities.html

Thank you for your reply, I am having a problem because your tutorial for the spawn egg is throwable. How would I do it normally?

[Eternaldoom]

When you register your entity, add two hex color params to the function and it will add a spawn egg with those colors.

Yeah I need to update the tutorial to include a regular spawn egg.

 

The problem is that the new way of registering entities does not allow you to register spawn egg at the same time.  So you have to create your own. 

 

To create your own spawn egg, you need to extend ItemMonsterPlacer.  "Monster Placer" is what spawn eggs are called in the code.  Then you can @Override the spawnCreature() method to return your custom entity instead of looking it up in the egg registry.  You'll also want to @Override other methods that look up the entity or spawn egg registery, like the getDisplayName() and such.  You may also have to do something to get the color right, I need to look at that more.  It is an item so you'll want to register it as a item.

[jabelar]

Okay, I went ahead and made a regular spawn egg.  I made it quickly, but seems to work.  Anyway, hopefully it gives you the right idea.

 

Create your own class as extension of ItemMonsterPlacer:

    }

}[code]

Make sure you register it like a normal item, in your common proxy pre-init handling method.  Something like this:
[code]     // can't use vanilla spawn eggs with entities registered with modEntityID, so use custom eggs.
     // name passed must match entity name string
     public void registerSpawnEgg(String parSpawnName, int parEggColor, int parEggSpotsColor)
     {
       Item itemSpawnEgg = new WildAnimalsMonsterPlacer(parSpawnName, parEggColor, parEggSpotsColor).setUnlocalizedName("spawn_egg_"+parSpawnName.toLowerCase()).setTextureName("wildanimals:spawn_egg");
       GameRegistry.registerItem(itemSpawnEgg, "spawnEgg"+parSpawnName);
     }

 

Of course you need to call the above method for each custom entity you create, passing it an egg color, etc.

 

Lastly, you need to copy the vanilla textures for the egg base and the egg spots and name them such that it matches the icon registration.

 

Hope that helps!
