- com.unity.entities 1.2.3
I’m new in DOTS and find trouble with the simple example.
I use a SpeedManager to try interation between MonoBehaviour and Entities. But I find that only the metrics in runtime inspector changes(like Local Transform and Local to World). However, the Cube in the Game didn’t move.
I try modify the value in the Authoring Inspector of Speed Authoring. The Cube finally moves in the game view. But the Console output still show that the speed are setting to 2, and local transform are moving towards right. Actually, in the Game view, the Cube is moving at a speed of -0.2.
And this is the ‘Mixed Inspector’ showing.

{
public class SpeedManager : MonoBehaviour
{
public float global_speed;
private void Start()
{
Debug.Log("SpeedManager Start!!");
global_speed = 2;
}
private void Update()
{
var entities = World.DefaultGameObjectInjectionWorld.EntityManager.CreateEntityQuery(typeof(Speed)).ToEntityArray(Allocator.Temp);
Debug.Log("entities.Length: " + entities.Length + " global_speed: " + global_speed);
foreach (var entity in entities)
{
var speed = World.DefaultGameObjectInjectionWorld.EntityManager.GetComponentData<Speed>(entity);
// Debug.Log("speed.value ori: " + speed.value);
speed.value = global_speed;
World.DefaultGameObjectInjectionWorld.EntityManager.SetComponentData(entity, speed);
// speed = World.DefaultGameObjectInjectionWorld.EntityManager.GetComponentData<Speed>(entity);
// Debug.Log("speed.value after: " + speed.value);
var transform = World.DefaultGameObjectInjectionWorld.EntityManager.GetComponentData<LocalTransform>(entity);
Debug.Log("transform.Position" + transform.Position);
}
}
}
