AvatarLib

1.1.1 ・ Public

AvatarLib

Contains a bunch of quick-to-use APIs for plugins and applications to add, modify a VRChat avatar. This is created because one or more tools of mine share the same code.

How to install

AvatarLib uses the Unity Package Manager (UPM) for version control. You can install the library by:

Start the Package Manager from Window -> Package Manager
Press the + icon and Add package from git URL...
Enter the URL: https://github.com/poi-vrc/AvatarLib.git?path=Packages/com.chocopoi.vrc.avatarlib

This URL tracks the latest master branch version
To change to a specific version, you can append #1.x.x at the end
- e.g. https://github.com/poi-vrc/AvatarLib.git?path=Packages/com.chocopoi.vrc.avatarlib#1.0.0
For details, check https://docs.unity3d.com/Manual/upm-git.html

How to update

Start the Package Manager from Window -> Package Manager
Next to the + icon, change to In Project
Find AvatarLib and press the Update to x.x.x button if available.

Why this library?

It is created to simply allow me to re-use some codes in multiple tools. But it is a really good library with handy library functions:

Easier VRCExpressionsMenu generation

With plain VRCSDK code, you will need to:

...
VRCExpressionsMenu menu = new VRCExpressionsMenu(); 
menu.controls.Add(new VRCExpressionsMenu.Control()
{
    name = "MyButton",
    type = VRCExpressionsMenu.Control.ControlType.Button,
    parameter = "this_is_a_parameter_1",
    value = 1.0f
});
menu.controls.Add(new VRCExpressionsMenu.Control()
{
    name = "MyToggle",
    type = VRCExpressionsMenu.Control.ControlType.Toggle,
    parameter = "this_is_a_parameter_2",
    value = 1.0f
});
VRCExpressionsMenu subMenuHere = new VRCExpressionsMenu(); 
menu.controls.Add(new VRCExpressionsMenu.Control()
{
    name = "MyAnotherSubMenu",
    type = VRCExpressionsMenu.Control.ControlType.SubMenu,
    subMenu = subMenuHere
});
AssetDatabase.CreateAsset(menu, "Assets/Menu1.asset");
AssetDatabase.CreateAsset(subMenuHere, "Assets/Menu2.asset");
...

...which is very long. But you can do this easier with AvatarLib:

// you can create a ExpressionMenuBuilder or directly create a sub-menu the avatar root menu
VRCExpressionsMenu myMenu = new ExpressionMenuBuilder()
    .AddButton("MyButton", "this_is_a_parameter_1", 1.0f)
    .CreateAsset("Assets/Menu1.asset")
    .GetMenu();

// or..
ExpressionMenuUtils.CreateSubMenu(avatar.rootMenu, "MySubMenu")
    .AddButton("MyButton", "this_is_a_parameter_1", 1.0f)
    .AddToggle("MyToggle", "this_is_a_parameter_2", 1.0f)
    .BeginNewSubMenu("MyAnotherSubMenu")
        .AddButton("SubMenuButtonHere", "this_is_a_parameter_3", 1.0f)
        .CreateAsset("Assets/Menu2.asset")
    .EndNewSubMenu()
    .CreateAsset("Assets/Menu1.asset");

Clean up your existing expression menus and animator stuff easier using Regex

// removes controls with name starting with "MyMenu "
ExpressionMenuUtils.RemoveExpressionMenuControls(menu, "^MyMenu ");

// removes parameters with name starting with "MyParameter_"
ExpressionMenuUtils.RemoveExpressionParameters(parameters, "^MyParameter_");

// removes layers with name starting with "MyLayer_"
AnimationUtils.RemoveAnimatorLayers(controller, "^MyLayer_");

// removes parameters with name starting with "MyParameter_"
AnimationUtils.RemoveAnimatorParameters(controller, "^MyParameter_");

Quick create animator layers with one-line of code

// Creates a AnyState--{condition}-->State layer!
//
//    [Entry] --------------------|
//                                v
//    [AnyState] --{if 0}-> [ myDefaultMotion ]
//         |
//          -------{if 1}-> [ motion1 ]
//         |
//          -------{if 2}-> [ motion2 ]
//         |
//          -------{if 3}-> [ motion3 ]

Dictionary<int, Motion> pairs = new Dictionary<int, Motion>();

pairs.Add(0, myDefaultMotion);
pairs.Add(1, motion1);
pairs.Add(2, motion2);
pairs.Add(3, motion3);

AnimationUtils.GenerateAnyStateLayer(controller, "MyLayer", "MyParameter_Integer", pairs, true);

Create World Constraint with code

Transform root = avatar.transform;

WorldConstraint wc = WorldConstraintUtils.CreateWorldConstraint(myGameObjectToBeInWorldSpace, root);

// animation clips generation

AnimationClip lockClip = WorldConstraintUtils.GenerateLockAnimation(wc);
AnimationClip unlockClip = WorldConstraintUtils.GenerateUnlockAnimation(wc);
AnimationClip showClip = WorldConstraintUtils.GenerateShowAnimation(wc);
AnimationClip hideClip = WorldConstraintUtils.GenerateHideAnimation(wc);
