Viewmodel

About Me

Vanilla Viewmodels is a Datapack Library which adds an “animation controller” for your OBJMC rendered viewmodels ingame. To work with the datapack, you must have:

• An Animated (Generic in Blockbench) Model.
• objmc installed locally.
• A Basic Understanding of How Resourcepacks and Datapacks work.

Using Viewmodel?

Pros

• Seamless Item Animations that can be ran per function.
• Thanks to OBJMC, the models can be extremely High-Resolution.

Cons

• The OBJMC shader doesn’t work with an IRIS shader on.
• The Resourcepack Size may bloat due to high res textures exported by objmc

Utility:

• ## How it works. Since objmc only exports model+texture, it should be noted that the datapack adopts certain conventions to make sure that it works as intended. OBJMC, by default, will not “prepare you a datapack/resourcepack” like how plugins like AnimatedJava does. Hence, creating a resourcepack that correctly follows this datapack’s convention is CRUCIAL.

Model in Resourcepack

The optional ‘id’ parameter accepted in the “play-animation” utils command requires a valid item_model component value. Since every objmc animation exports into its own model+texture, you must:

• Create an Item Model JSON that resembles the model. e.g. 'first_person:weapons/glock' at assets/first_person/items/weapons/glock.json
• Animations for the Model MUST be included in this item_model folder, where the “model with animation” is a model toggled when STRING CUSTOM-MODEL-DATA value === ANIMATION-NAME.

Hence, every animation is a CustomModelData string in the item_model JSON file. Obviously, this implies that adding multiple animations would mean that you’ll have to export every animation into its OBJ sequences => put them through OBJMC.py => take the condensed model and mention it in the item_model component.

Registering Models in Datapack.

To Register an OBJMC Animated Model in the datapack, open the function file vm:global/load and add a registry in the data modify line!

Here’s how a registry entry’s structure looks like:

{
  id: "first_person:weapons/glock", // item_model component
  animations: [
      {
          "name":"equip",
          "start": 0,
          "end": 27,                                      // The Total Ticks of the Animation
          "duration": 30,                                 // Ticks of Animation with Dead Space
          keyframe_functions: [
            { at: 0, function_file: 'test:equip' },       // Run a function file @ 0th keyframe.
            { at: 30, function_file: 'test:end_animation' },
            { at: 25, function_file: 'test:gun_sfx' }
          ]
      },
      {
          "name": "shoot1",
          "start": 0,
          "end": 8,
          "duration": 6,
          "keyframe_functions": [
              { at: 0, function_file: 'gun:shoot' }
          ]
      }
  ]
}

To register an animation that loops infinitely, set the “end” value to -1

• ## Playing an Animation

to play an Animation, run the command:

function vm:animations/play {args:{}}

the args:{} field is used to tweak parameters, namely:

id: it stores/applies the *item_model* component value
animation: it stores the name of the animation.
frame: the frame at which the animation should start.

an example command:

function vm:animations/play {args:{id:"first_person:weapons/glock", animation: "equip", frame: 10}}

This command will,

• change the item model of the potion item to first_person_weapons/glock
• set the animation-to-be-played to “equip” (this is handled by setting animation name equal to custom_model_data string that changes the model into one with different animation texture data)
• set the starting frame to 0 (potion color is set to 8388608+10)

• ## Stopping an Animation

to stop an animation, simply run the command:

function vm:animations/stop
