Hi, Is there a way to use event subscription to call system functions? Thanks

zllangct commented 2 years ago

I think we should change the mode of thinking, this is ECS, not OOP. this rep is a concurrency system with lock-free, all logic drived by "frame", ecs benifit from the the independent "system", your system can call diffrent function by changing component field, a system shoud not communicate with others directly. you can add a new single-use component with some data what you want to send to the system when you want to publish an event.

cchandel commented 2 years ago

Ok, That makes sense.

Could you provide example of how both options would work?

Thanks.

zllangct commented 2 years ago

Good idea, I'm planning to do it, the way to program is very different from what we used before, we need more examples

cchandel commented 2 years ago

For Eg, Lets say the game has the ability to change its speed - which means at speed 2 every thing becomes 2 times as fast, actor movement, game time etc.

How would this be handled in your view?

zllangct commented 2 years ago

I see, you want to modify system by event，such as the time-scale of system and other system field, i think u r right, it's very useful. I will add this capability in future. Thanks.

Hi, Thank you for the fake_game example and for adding events to the ECS system. Regards

Hi, this rep's apis are unstable, will be optimized or changed continuously before release version, Thanks for your proposal.

zllangct commented 2 years ago

fake_game_server example is incomplete, more usages will be added to this example.

cchandel commented 2 years ago

Sure. Understood.
