ScreepsOS

An Kotlin coroutine based operatingsystem framework for Screeps

How to get started

You need to:

• Implement your own Scheduler (feel free to base it on the provided ExampleScheduler)
• Give the function to know which tick it is ({ Game.time } will do)
• Spawn your first process:

val scheduler = YourScheduler()

kernel = Kernel.create(scheduler) { Game.time } 

val mainProgram = MainProgram()

kernel.spawnProcess(mainProgram, priority = 1)

Then you can start looping:

fun mainloop() {
  kernel.loop()
}

Implemented functions

• yield() Returns control back to the kernel, letting your Scheduler decide what to (if anything) to run next. Used for splitting up heavy tasks over several ticks
• sleep(10) - Puts the process to sleep for 10 ticks, and returns control to the kernel
• wait({Intel.hasVisibility(roomName)}, , checkInterval = 5) - Waits until the condition is true before continuing. In this example we wait for {Intel.hasVisibility(roomName)} to become true, checking every 5 ticks.
• exit() - Exits the Process. The Program will still be accessable until all references is gone and it is removed by the GC.

To utilize yield(), sleep(), wait() and exit() you need the suspend keyword on your function call-chain outwards from Program.execute().
