Systems not running in default_systems.tscn

[DragonAxe]

I have organized my systems by SystemGroup's in a default_systems.tscn:

I have attached that scene to my startup scene:

In my Main node's script, I have the following:

Do I still need to register each system with ECS.world.add_system(), even though they are available in the scene tree?

Here's the running scene tree and GECS debugger:

Try this make sure you're assinging your Entity Nodes Root and Your Systems node Root and then move your DefaultSystems underneath that System Nodes Root.

Then when you do ecs.process(delta) it will execute all your systems

Thanks for the quick response!

Unfortunately, doesn't seem to have worked.

Although, the World node does have my 3 systems in it's Systems member, but they don't get executed and don't show up in the debugger.

Ah ya, so you either need to tell your system groups to run or you need to remove the system groups and just use a blank string '' on the system node group property

doing ecs.world.process(delta) will only run the systems in the '' group which is system in no group.

Since all of your systems are grouped, you need to call the group to execute.

ecs.world.process(delta, 'group_name')

Ah ha! Yep, that did the trick! Thank you for your help!
