[1.10.2] How to Replace/Add to Vanilla Item Models/Textures and Potion Questions

Recommended Posts

What I am trying to do is change the texture of the potion, but only for my potions. How would I do this? I tried using setCustomMeshDefinition, but getModelLocation never seemed to be called. Also with potions, is there any way to increase/decrease mob spawns while having a custom potion effect active?

Quite hacky, but this should work:

 

All in preInit:

  • Register an implementation of
    IItemPropertyGetter

    to

    Items.POTIONITEM

    using

    addPropertyOverride

    with a

    ResourceLocation

    with your ModID.

    • In this
      IItemPropertyGetter

      , check if the supplied stack is your potion and return 1 if so, 0 otherwise.

    [*]Implement

    IResourceManagerReloadListener

    and register it with

    Minecraft#getResourceManager

    (you'll have to cast to

    IReloadableResourceManager

    ).

    • In this listener, call
      Minecraft.getMinecraft.getRenderItem().getItemModelMesher().getItemModel(new ItemStack(Items.POTIONITEM));

      to obtain the baked model for the potion.

    • Obtain the
      ItemOverrideList

      for the model using

      IBakedModel#getOverrides

      and get the field

      ItemOverrideList#overrides

      from it (you'll need reflection as this field is private).

    • This field gives you a
      List<ItemOverride>

      . Create your own

      ItemOverride

      and add it to the list. The constructor for

      ItemOverride

      takes 2 parameters: A

      ResourceLocation

      and a

      Map<ResourceLocation, Float>

      . The

      ResourceLocation

      is the identifier for the model you want your potion to have (like you would use when normally registering an item). The

      Map

      needs to contain a single entry, the key being the

      ResourceLocation

      that identifies your

      IItemPropertyGetter

      from the first step, the value being (as a

      Float

      ) 1.

 

You might additionally need to tell Minecraft to pre-load your Model using

ModelBakery.registerItemVariants

in preInit.

How do you want this to work? If a player has this potion active, mob spawns around them are reduced? Does it also happen when other (not-affected) players are nearby?
