Can I use Immediate Mode in ECS System?

I would like to use IM in a system like the following:

public partial class SomeSystem : SystemBase
{
protected override void OnCreate()
{
base.OnCreate();
}

protected override void OnUpdate()
{
Entities.WithAll().ForEach((in DrawingData someData) =>
{
Draw.Line();
}).WithoutBurst().Run();
}}

Would it be possible to access IM from within such an Entites ForEach loop?

I haven't designed it to be used with ECS, I don't know all the intricacies of how it handles rendering and command buffer dispatch. So I don't know I'm afraid! I've heard some who haven't been able to use it together with ECS, so I don't think it's supported, but it's possible it might work in certain configurations

Worst case, you can always try it and refund in case it doesn't work out!

It does work as simple as that!:

protected override void OnUpdate()

{

using (Draw.Command(Camera.main))
{
Entities.WithAll().ForEach((in DrawingData someData) =>
{
Draw.Line();
}).WithoutBurst().Run();
}

}}
