how to properly handle input/events?

[mvl]

Hello,

I Read the SFML game development book, and am very interested in how it handled input/events in its command based system. Is there anymore information on that subject? Also is this the best way if situational what other good methods are there? Should input be separated from other events? Should other systems than the entity system receive events? If so with the same system as the entities or different ones?

please help me and thank you for reading my post  .

If you read the book, which part did you not understand? It's fully explained in the book...

There are always multiple ways to go about something. What is your use case?

I did understand but just extra info for maybe different ways, for example if i google command based communication system i don't really get anything useful. maybe some source that it in a bit more detail maybe a comparison with other alternatives what alternatives are there could you even do a full game without one?

The handling of input is nothing special. The basis is that when an event or input happens some form of a callback function gets called.

The command pattern from the book is one way and fits their game.
They do mention the message bus pattern which is a different way of doing things, but it can go beyond just input or system event.
The Thor library has yet again a different approach and enables you to uniformly handle realtime input and events.

Overall input/evenf handling is the relatively easy part of writting a game and it's important to choose a system that goes hand in hand with your game.
