How can I create global tag handles?

[hw762]

I tried to do ECS_COMPONENT_DECLARE(SomeTag) followed by ECS_TAG(ecs, SomeTag). Unfortunately, this does not seem to work, as it fails an assertion: flecs.c: 7856: assert: ecs_id_is_valid(world, id) INVALID_PARAMETER. Is it possible to create global tag handles?

If you want to forward-declare an entity that's not a component (created with ECS_COMPONENT) then you can use ECS_DECLARE.

As seen in the fwd_declare_component example:

// To forward declare entities created with ECS_ENTITY, ECS_TAG or ECS_PREFAB,
// use ECS_DECLARE.
ECS_DECLARE(Wizard);
