Pseudocode for a very basic event system in a game engine
At a high level, events work as follows:
- Each type of event must have a unique name or ID (e.g. "user_joined_game")
- Each type of event may have additional metadata (e.g. the "user_joined_game" event will likely have a "user_id" in the metadata)
- Zero or more event handlers (in the form of callback function, also sometimes called "listeners" and owned by "subscribers") can be registered for each type of event. This can be done in many different ways, one way would be to have a central event manager that keeps track by having a list of subscribers for each type of event. In a more advanced implementation, you could also have filters (e.g. only send me "user_position_changed" events for "user_id = 5"). I would recommend starting with a simple boolean "handled" flag as a filter to start (see below).
- Zero or more places where an event is fired (also called "triggered", done by a "publisher").
- When an even is fired/triggered by a publisher, it goes into an event queue. Generally you'd have one portion of a

Cross-platform, drop-in, high resolution timer for C/C++ projects.

Easy embeddable cross-platform high resolution timer function. For each

function in your file after embedding this.
