Allows avoiding repeating HasComponent ? GetComponentData : default pattern. Extension method for Entity Manager in Unity Entities.

EntityManagerTryExtension.cs

using Unity.Entities;

public static class EntityManagerTryExtension
{
    public static bool TryGetComponentData<T>(this EntityManager em, in Entity e, out T data) where T : struct, IComponentData
    {
        if (em.HasComponent<T>(e))
        {
            data = em.GetComponentData<T>(e);
            return true;
        }
        
        data = default;
        return false;
    }
    
    public static T TryGetComponentData<T>(this EntityManager em, in Entity e, T fallback) where T : struct, IComponentData
    {
        return em.HasComponent<T>(e) ? em.GetComponentData<T>(e) : fallback;
    }
