EntitiesBT on OpenUPM

Hi @quabug ,

Thanks for creating the amazing project. I'm the creator of OpenUPM, a public upm registry with automatic build pipelines that publish new package bundle based on semver git tags. You can read the announcement to get the basic idea, so far it hosts 80+ packages as of December 2019.

I have added this package: https://openupm.com/packages/entities-bt/. To make it useful, could you please

Make a GitHub Release for v0.2.0
[Optional] consider adding a badge.

License

What is the license on this work?

Generate `EntitiesInternalMethods.dll` on `ILPostProcessor`?

[SubScene] `EntityQueryMask` is not match

Entities 0.17.0-preview.41 Not Working

I think this is Fatal Error in EntitiesBT.

Expression variant

Create a tree of variant from a string input.

class Assign<T> : IVariant<T> where T : unmanaged
{
    public IVariantWriter<T> Left;
    public IVariantReader<T> Right;
}

class Add<T> : IVariantReader<T> where T : unmanaged
{
    public IVariantReader<T> Left;
    public IVariantReader<T> Right;
}

class Normalize<T> : IVariantReader<T> where T : unmanaged
{
    public IVariantReader<T> Value;
}

class SomeExpressionReader<T> : IVariantReader<T> where T : unmanaged
{
    public IVariantReaderAndWriter<T> Foo;
    public IVariantReader<T> Bar;
    public string Expression; // "$Foo = $Foo + normalize($Bar)"
                              //     => Assign(Left: Foo, Right: Add(Left: Foo, Right: Normalize(Value: Bar)))
}

Graph input data of behavior tree must be at the same graph as `BehaviorTreeBuilder` located.

`InvalidOperationException` after an Entity is destroyed

This issue only happens when two or more entities have the same tree source. Any cleanup steps are required before destroying an Entity with BehaviourTreeRoot?

The full call stack is as follows.

Failed to run Sample properly

I tried to run the sample but log me error and warning. Any idea what the cause and how to fix them?

[SubScene] `Entity` of `BTDebugViewTreesManager` is not the same as entity in default world

monorepo and inconsistent sub-package versions

Hi @quabug,

You have a good monorepo setup, but your sub-package versions are inconsistent. i.e. for Git tag 0.21.2, some package may be still versioned with 0.21.0. This is not a problem, but it confused openupm build pipelines that not all package versions are matched with the tag version.

Two options

Keep all sub-packages versions synced with your Git tag version. This will also send your user a clear signal that whether all packages are synced, but a user may force to do unnecessary updates for packages not get real updated.
Create a Git tag for an individual package with a related prefix, and ask openupm-cli to track the Git tag prefix instead. ReeseUnityDemos is an example. The sub-package com.reese.random ask our pipelines to track random prefix. The author @reeseschultz is creating a tool called https://github.com/reeseschultz/ubump to automate the process.

You can also ignore the issue, and version conflict errors on your openupm page like https://openupm.com/packages/com.quabug.entities-bt.builder.component/.

Optimize il code generator of variants

It takes more than 5s on 5800x for generating variants of all primitives and Unity.Mathematics types.

`EntityQuery` cannot be used in `ISharedComponentData`?

BlackboardDataQuery.cs

Analyze `Tick` and `Reset` methods of node code and generate `ComponentType` automatically?

How to access entity data by ComponentType in Job?

https://forum.unity.com/threads/is-it-possible-to-access-data-of-entity-by-componenttype-or-typeindex-in-job.802569/

I have tried create a NativeHashMap<int/*TypeIndex*/, ArchetypeChunkComponentTypeDynamic> and pass it into Job, but ArchetypeChunkComponentTypeDynamic cannot be used in NativeContainer.

        struct Job : IJobChunk
        {
            // ArchetypeChunkComponentTypeDynamic is not a valid type of NativeContainer
            public NativeHashMap<int, ArchetypeChunkComponentTypeDynamic> Types;
         
            public void Execute(ArchetypeChunk chunk, int chunkIndex, int firstEntityIndex)
            {
                chunk.GetDynamicComponentDataArrayReinterpret<A>(Types[ComponentType.ReadOnly<A>().TypeIndex], UnsafeUtility.SizeOf<A>());
            }
        }

What did I do wrong?

Move deprecated code out into a separated package.

generate il code of `SerializableNodeData` for each `INodeData`

no need to create a new BTNode for each INodeData.

Print error log if there's no `BehaviorNode` attribute on an `INodeData` structure.

Use constraint type interfaces for `IBlackboard`?

Is this a clearer and distinct way to declare IBlackboard?

public interface IBlackboard
{
    T GetData<T>() where T : strcut, IComponentData;
    ref T GetDataRef<T>() where T : strcut, IComponentData;
    T GetManagedData<T>() where T : class, IComponentData;
    T GetSharedData<T>() where T : strcut, ISharedComponentData;
    T GetUnityComponent<T>() where T : UnityEngine.Component;
}
