#Screeps constants code

In JavaScript this is not a problem, because you either assume the correct type or verify the type otherwise e.g. For example, room.find(FIND_CREEPS) finds all creeps in a room, room.find(FIND_FLAGS) finds all flags, and so forth. The Screeps API has a number of functions that take in a constant specifying a type and return an object of that type. How do I parse function return values into the correct types?

#Screeps constants code

In the end the JS code just passes in objects like it always does, but with strong compile-time guarantees about correct objects being passed within our code. Also, all of these types are defined only at compile-time and disappear at run time. RoomObject (RawStructure RawContainer) = RoomObject a Borrowing an example from the PureScript Wiki: Write a foreign import type declaration for how you want to call the function and a corresponding JavaScript function that actually calls the function (and handles currying). How do I call a JavaScript function from PureScript? Here is what I ran into and how I ended up solving it. How do IвЂ¦ДЄs a relative newcomer to PureScript and strongly typed functional programming languages, I ran into a number of puzzles in wrapping the Screeps API. But I gave a shot at wrapping it and IвЂ™m pretty happy with the result. Performance is important, because the game caps the amount of CPU and memory you can use. It makes heavy use of prototypes, a class hierarchy, and implicit effects. PureScript is a small strongly typed language that compiles to JavaScript.ДЄs a target for PureScript, the Screeps JavaScript API has some challenges. EveryoneвЂ™s code runs 24/7 across hundreds of rooms in the same world. You play by writing a JavaScript AI to control your minions. Screeps is an MMO strategy game for programmers. How do I wrap a JavaScript API to use from PureScript? I had a chance to think about this while wrapping the Screeps game API so I could play Screeps using PureScript.
