Runtime

Most of RMML’s code is concerned with populating global.rmml_map as quickly as possible. However, something needs to read that map and actually run modded Event code. RMML’s runtime has changed drastically between versions, so let’s go over the latest.

Rusted Moss runs modded Event code using Events that look like this.

// gml_Object_omod_controller_Create_0
// check if the function exists
if ds_map_exists(global.mod_map, "controller_events_create")
{
  // ensure `self` gets set to this Game Object
  ds_map_find_value(global.mod_map, "controller_events_create").setSelf(self)
  // call the stored function
  ds_map_find_value(global.mod_map, "controller_events_create")()
}

Each Event has its own key, based on the Game Object and Event names. global.mod_map is a ds_map, and maps these event keys to Catspeak function calls.
