Tameable Mobs?

[SureenInk]

Okay, so...I don't understand the coding for wolves...there's a lot of "func" stuff, and I don't understand any of that...I copied stuff out of wolf and into another entity the best I could, and even tried tweaking the code a bit. I can make the mob tameable, but I can't get them to breed or follow the player once tamed. I'm also not sure how to make them sit...Could someone help me out? Here's my current code. I don't really want someone to give me code to fix it as much as I'd like someone to help explain the code that is there and what code I'm missing to make them work. (Also, when I give them meat, which I guess is the breeding item, it crashes completely).

ItemFood (porkchops) heals the dog/wolf when he is tamed.

Items.bone (from skeletons) can tame the wolf (with some random chance) unless he is angry.

isBreedingTime returns true if the item passed in is the wolfsFavoriteMeat (property held by an ItemFood:  like porkChop)

Most of the otherstuff is pretty standard tameable methodology.

I don't know where the follow player code come into play.

[coolAlias]

It crashes when you give your mob meat because you are using the EntityWolf's code exactly:

 

this.dataWatcher.getWatchableObjectFloat(18) < 20.0F

 

DataWatcher (18) is added during entityInit for EntityWolf, but you do not add it - wolves use it to track current health, though I'm not really sure why that's necessary.

 

As for sitting, the animation isn't going to happen automatically; chances are the entity IS sitting when you tame it, but since their is no animation you can't tell and just think it's not following you. Try right clicking it again after you tame it and see if it doesn't follow you around, or put in a println statement in your interact method to tell you the sitting state.

[SureenInk]

Oh! lol I had to right-click her without something in my hand to make her unsit. I feel dumb! Thanks for that bit of info! She seems to work fine now. Now I just have to figure out how to get her to spawn and how to change the food and make her able to breed (well, I also need to make a sitting animation somehow)

[saxon564]

The wold doesnt use an animation when you make it sit. The way the model is called changes so it is rendered differently. Just like many mobs have an "isBaby" call to change the model the same goes with the wolf.
