New Input System implementation with DOTS (ECS, Jobs, Burst)

Questions & Answers
1

Hello, I am currently a noob for DOTS and learning the job system with ECS and the Input System. I am currently generating an entity with the default cube mesh and I want it to interact with the new Input System package (currently 1.0.1). If anyone knows how to implement the new Input System with Jobs and ECS, I would be really grateful to you.

Thanks in advance.

This is probably the most basic implementation to marry InputSystem with ecs now:

// PlayerAuthoring.cs
using UnityEngine;
using UnityEngine.InputSystem;
using Unity.Mathematics;
using Unity.Entities;
using Unity.Transforms;

public class PlayerAuthoring : MonoBehaviour, IConvertGameObjectToEntity
{
    void IConvertGameObjectToEntity.Convert ( Entity entity , EntityManager dstManager , GameObjectConversionSystem conversionSystem )
    {
        dstManager.AddComponent<PLAYER>( entity );
    }
}

public struct PLAYER : IComponentData {}

public class PlayerMovementSystem : SystemBase
{
	protected override void OnUpdate ()
	{
        float dt = Time.DeltaTime;
        float3 inputs = default(float3);
        const float speed = 5f;
        
        // replace this code with your own input mapping method:
        var keyboard = Keyboard.current;
        if( keyboard!=null )
        {
            inputs = new float3{
                x = keyboard.dKey.ReadValue() - keyboard.aKey.ReadValue() ,
                y = keyboard.spaceKey.ReadValue() - keyboard.leftCtrlKey.ReadValue() ,
                z = keyboard.wKey.ReadValue() - keyboard.sKey.ReadValue()
            };
        }
        
        Entities
            .WithName("basic_locomotion_job")
            .WithAll<PLAYER>()
            .ForEach( ( ref LocalToWorld transform , in Entity entity ) =>
            {
                #if UNITY_EDITOR
                Debug.DrawLine( transform.Position , transform.Position+inputs , Color.yellow );
                #endif

                transform.Value = math.mul(
                    transform.Value ,
                    float4x4.Translate( math.normalizesafe(inputs) * speed * dt )
                );
            } )
            .WithBurst().ScheduleParallel();
	}
}
