How can I create sprite entity?

Below is my code but it's not working. No sprite been created.

Code (CSharp):

1.  
2. EntityArchetype entityArchetype = EntityManager.CreateArchetype(
3.     typeof(Translation),
4.     typeof(Sprite2DRenderer),
5.     typeof(Sprite2DRendererOptions),
6.     typeof(LayerSorting)
7. );
8.  
9. Entity entity = PostUpdateCommands.CreateEntity(entityArchetype);
10.  
11. EntityManager.SetComponentData(entity, new Translation { Value = new float3() });
12. EntityManager.SetComponentData(entity, new Sprite2DRenderer { color = new Color(1, 1, 0) });
13. EntityManager.SetComponentData(entity, new Sprite2DRendererOptions { size = new float2(25, 10) });
14.  

 

Do you want to change sprite of an entity by creating a new one? If that is the case you should first get the sprite on a component from the editor as an entity.

 

Nope. I want to create like if you select / clicked the unit / player it will create a highlighted.

 

1 - If you put a child entity to your unit entities and that child entity has a Sprite2DRenderer component with the "highlight" sprite; then you can Enable/Disable that entity by adding or removing Disabled() component to/from it.

OR

2 - Get a reference to "highlight" sprite, whenever you need it you can assign it to an entity with a Sprite2DRenderer component.

In both cases you don't need to create a new sprite in runtime. But after all if that's what you need to do, I haven't figured out how to do it yet.

Good luck!

 

Are you sure that not created? May be you mean not rendered? Try add LocalToWorld type.

 

How can I read the child component? do you have any sample code or reference for me sir?

 

Already did that also. the sprite still not appear. thanks

 

Hi techielabmy,

Have you tried:

1- adding a LayerSorting order value in case it is under something?

Code (CSharp):

1. LayerSorting lay = new LayerSorting { order = 1 };
2. EntityManager.SetComponentData(entity, lay);
3.  

2- And you may need also to add a sprite when you create your Sprite2DRenderer, not only set the color

 

Just add a component to the child entities. Then use Entities.WithAll<ChildEntityComponent>() to get your child entities.
