Issues with non active objects

Hello there,

I am receiving some issues with working with the ecs right now, i didn't expect and cannot really explain, so i am low with workarounds.
I have implemented the new Input System into an InputComponentSystem, which is capable to receive all that inputs and put it into a seperate PlayerController, which has nothing more in it, than just the input and a given id.

Then i have several entities inside the area, which share the same id and receive input from another system, which i can easily swap around.

Somehow everything works ...
But it only works, if i have the component, that should receive input active in the hierarchy.
Whenever i loose focus in hierarchy it stops working.

And - if you can imagine - when build into a game, i have no hierarchy anymore, where i would focus objects.

So it looks like i show in the small youtube video down here, and i can't really say, what's going on.

The ComponentWrapper are no voodoo, and the component itself also just holds float...

Code (CSharp):

1. [System.Serializable]
2. public struct UpdateFloatValue : IComponentData
3. {
4.     [SerializeField]
5.     public float Value;
6.  
7.     public UpdateFloatValue(float value)
8.     {
9.         Value = value;
10.     }
11. }
12.  
13. public class UpdateSliderComponent :  ComponentDataWrapper<UpdateFloatValue>
14. {
15.     Slider slider;
16.     private void Start()
17.     {
18.         slider = GetComponent<Slider>();
19.     }
20.  
21.     void LateUpdate()
22.     {
23.         float sliderValue = (Value.Value + 1)*.5f;
24.  
25.         slider.value = sliderValue;
26.     }
27. }

 

From memory this doesn't work

Code (CSharp):

1.         float sliderValue = (Value.Value + 1)*.5f;
2.         slider.value = sliderValue;

The value field on the ComponentDataWrapper is only updated when you have the entity selected. It's for viewing/debugging only.

 

So what would i want to do instead with it to receive my UI ?

I understand the problem, but not the solution.

Thank you for answering !

 

Code (CSharp):

1. using Unity.Entities;
2. using UnityEngine.UI;
3.  
4. public class UpdateTextSystem : ComponentSystem
5. {
6.     unsafe public struct TextGroup{
7.         public Text Text;
8.         public UpdateFloatValue* UpdateFloatValue;
9.     }
10.  
11.     unsafe protected override void OnUpdate()
12.     {
13.         var entities = GetEntities<TextGroup>();
14.         for (int i = 0; i < entities.Length; i++)
15.         {
16.             var entity = entities[i];          
17.             entity.Text.text = entity.UpdateFloatValue->Value + "";
18.         }
19.     }
20. }
21.  

This does the job.

But i really really don't know, if i do good, doing this...

Is it usual to have unsafe code for various situations ???

 

It is fine to access something like this through Monobehaviour and then set the values with EntityManager. Here's an example where the player in my game shoots with a mono component and damages entities.

Code (CSharp):

1. void DamageEntity(GameObject entityGO){
2.         var entity = entityGO.GetComponent<GameObjectEntity>();  
3.         var target = entity.EntityManager.GetComponentData<Health>(entity.Entity);
4.         target.value -= 15f; //-weapon_dmg
5.  
6.         if(target.value <= 0 ){
7.             entity.EntityManager.AddComponentData(entity.Entity, new DeadUnit{});
8.             entityGO.layer = 14;
9.         }
10.         else{
11.             entity.EntityManager.AddComponentData(entity.Entity,new DamagedAnimation{});
12.         }
13.         entity.EntityManager.SetComponentData(entity.Entity,target);
14.     }
