[DK] Headcrab [DK] Posted May 16, 2020 Share Posted May 16, 2020 Hello, I were wondering if there were any recommendations on the use of many event handlers? My mod adds custom perks, and most perks trigger at different events. To make maintenance easier I would like to have all code related to the perk in its own class, so I was thinking about using the "@Mod.EventBusSubscriber" notation on each of the perk classes, and then use the "@SubscribeEvent" notation on the correct event to implement the functionality. If my mod addes 30 perks, it means I will be registering 30 new event handlers, and since im unsure of the actual inner workings of Forge, it made me wonder if having many EventHandlers could have an impact on performance? So, is it recommended to use a single EventHandler that subscribe to all relevant events, and call the correct methods in each perk, or is the performance impact negligable if any from using many handlers?

Draco18s Posted May 16, 2020 Share Posted May 16, 2020 Virtually zero. One hundred classes that each listen for one of one hundred separate events has the (nearly) the same impact as one class with one hundred listeners in it. The difference is all start-up time when Forge has to do discovery and some bytecode magic to create the hooks, but runtime is going to be the same. 1 Quote Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.
