Entities.Foreach.Run causes Invalid IL code
In my system, it is necessary to go through some entities if a certain condition is met. To do this, I use Entities.Foreach.Run. As a result, an error occurs:
InvalidProgramException: Invalid IL code in ECS.Systems.ContainerSelectSystem:OnUpdate (): IL_01a7:
However, if you call Schedule instead of Run, there will be no error. Also, there will be no error if I make exactly the same bypass from the If block.
Example code:
[UpdateInGroup(typeof(SimulationSystemGroup))]
//[DisableAutoCreation]
public class ContainerSelectSystem : SystemBase
{
public const float maxDistance = 300f;
BuildPhysicsWorld _buildPhysicsWorld;
protected override void OnCreate()
{
_buildPhysicsWorld = World.GetExistingSystem<BuildPhysicsWorld>();
RequireForUpdate(GetEntityQuery(new EntityQueryDesc
{
All = new ComponentType[] { typeof(Container) }
}));
}
protected override void OnUpdate()
{
if (Input.GetMouseButtonDown(0) && (Camera.main != null))
{
var mousePosition = Input.mousePosition;
var ray = Camera.main.ScreenPointToRay(mousePosition);
var raycastInput = new RaycastInput
{
Start = ray.origin,
End = ray.origin + ray.direction * maxDistance,
Filter = CollisionFilter.Default,
};
var collisionWorld = _buildPhysicsWorld.PhysicsWorld.CollisionWorld;
RaycastHit hit;
if (collisionWorld.CastRay(raycastInput, out hit))
{
var index = EntityManager.GetComponentData<Container>(hit.Entity).Index;
Debug.Log("Сheck: " + index);
var stopwatch = new Stopwatch();
stopwatch.Start();
Entities
.WithoutBurst()
.ForEach((Entity entity, in Container container) =>
{
if (container.Index.y == index.y)
Debug.Log(container.Index);
})
.Run();
stopwatch.Stop();
Debug.Log(stopwatch.Elapsed.TotalMilliseconds);
}
}
}
}
Error message you provided is incomplete. Copy & paste full message details.
I have no idea which version of unity.entities and unity.physics packages you're running here. But I tested this code on both 0.17p42+0.6.0p3 and 0.50+0.50 and I see no errors.
I found the reason quite by accident. The error was thrown because of StopWatch. The solution was also found by chance: instead of creating a new StopWatch variable before traversing entities, I put it in the class field. I don't understand how it works behind the scenes.
