Tamed Mob not following and question about sitting implementation

Posted August 10, 201510 yr

Hi all,

Just starting out in the forge world with a mod for my daughter - modelling her bear in MC - unfortunately, I cannot seem to get the mob to follow me once tamed. I have checked whether or not the mob is sitting (although I have no animation for that yet) and checked the EntityWolf class for clues but I just cannot figure it out. Everything else works, breeding, taming and following me when I hold an apple (set to fav).

Also, can anyone give me any pointers on how to create a sitting animation / code ?

Any help appreciated!

Jim

Well, the best way to debug such things is to trace the execution to see if everything is behaving like you expect. You can put logger or console statements (like System.out.println() method) in each method of your entity and AI classes, where the statements print out values of the key fields. Then you can usually quickly determine what is going wrong.

Just looking quickly at your code, I'm wondering if your setTamed() method should be calling the setTameValue() method as well. I don't see where the datawatcher value is being updated if you don't call that. So perhaps it is never really getting tamed due to you not setting that value.

I have some tutorials that might interest you as well:

Hi,

I am still having trouble getting my entity to follow me when it is tamed. Tamed and owner is being set once the entity is tamed and isSitting is false when I right click on the entity with an empty hand in game.

I have tried everything I can think of. Can anyone see where I am going wrong please?

Many thanks

Jim

Try replacing implementation with minecraftLibrary. Dependencies in the minecraftLibrary configuration are added to your compile and runtime classpaths in ForgeGradle 6.

Failed loading villager cartographer registered at cartographer - frozen tick

Allocated 10 Gb of ram. Could try again with more but I read using too much can slow things down as well. Going to try another big modpack and see if i can replicate the problem. It seems like this cartographer problem is kind of popular and doesn't have a solid solution yet, but i suspect its some generation mod since it's a crash that happens when specific chunks are being loaded. so i'll still try to lookout for what mod it could be as i add. i'll report back after testing as you suggested for a bit
