Let's start off with... I'm an experienced Java programmer (25+ years between assembly, c, c++ and java) and have some recent experience with Minecraft (especially the event handling and task scheduling, which are most relevant to my question). So, I'm not looking for anyone to give me specific code for anything... (aka do my work for me). My question is really what is the best way to do something with the constraints of the available API's. I need to grab a timer tick and perform different actions at different unrelated intervals. I have worked a test system where I can accomplish this is with scheduling a repeating thread to start-up, check the time and do its thing for that period. My gut has me worried that spawning a repeating task like this has a lot of overhead and could cause lag. I've also looked around extensively to find some sort of timer tick event I can monitor with an event handler instead - again my gut says this would more efficient and the developers should have provided some sort of event like this to monitor. My concerns may actually be a moot point because at worst case the event would only be triggered every 10 seconds (an eternity in computer time). Any recommendations as to the best way to handle this timer tick issue? Your assistance is appreciated!
