I have a collision system that detects when triggers on asteroids are hit and stores asteroid data, the point of collision, the player ID, etc in a NativeArray. I would like to use that data in another system to spawn "mined resources".

The collision might look like this:

public struct AsteroidHitList : IBufferElementData
{
    public LocalTransform position;
    public int playerProjectileOwnerId;
    public int resourceGeneratedTypeId;
}

public partial struct BulletTriggersOnAsteroidsSystem : ISystem
{
    NativeList<AsteroidHitList> resourcesArray;

Then I would want another system to generate resources... maybe something like this. What would be the proper way to share these data between systems:

public partial struct SpawnResourcesSystem : ISystem
{
    public void OnUpdate(ref SystemState state)
    {
        World.GetExistingSystem<BulletTriggersOnAsteroidsSystem>().resourcesArray
    }
}
