Could I change the execution order of systems at runtime?

[carloslab-ai]

Hi everyone,

I've encountered some cases in which I needed to change the running order of systems at runtime.
Although I can solve my problems by adding something like a DecisionMakingSystem to determine which system will be run next.
But I think it would be better if I could change the running order of the systems.

Therefore, I have two questions that I want to ask you guys:

1. Could I change the running order of systems at runtime in SveltoECS?
2. Have you encountered any cases where you needed to change the running order of systems?
   If yes, what solution did you use to solve the problem?

as you know Svelto doesn't have any ticking system nor takes any responsibility on execution order. In few words you create your own custom engines group and do whatever logic you prefer for the ticking.

all that said, needing to change execution order MAY be a design mistake.
