Re: Tron clone in Clojure

Here's a 2D game I wrote in Clojure for comparision: http://github.com/ShardPhoenix/SAGame This was my first significant Clojure program so the code is a bit rough, but the core game state is handled in a pure-functional way, and is continuously passed around the main loop. -- Ryan Sattler -- Y

Hi Carlos, This certainly looks like a bug. I've filed issue 768 on myself (http://dev.clojure.org/jira/browse/CLJ-768) and I'll take a look as soon as I get a chance. Thanks for bringing this up, Tom On Apr 3, 1:49 pm, Carlos Ungil wrote: > Hello, > > I don't know if there is a better way to

How to profile my app?

Hi Group! I am hoping to get a little help figuring out how to profile my app. I have been working on this for a while and appear to have a bottleneck somewhere. I could attempt to manually step through the app step by step, but I am looking to see if there is a better solution. How to you all

Re: Protocols and name collisions

You can't turn clojure.core/first into a protocol - it's already a bare function. When you define a protocol with a first method, you define a new function in your namespace called first, which delegates to protocol implementations. The compiler is complaining that you're shadowing clojure.core/fir

Protocols and name collisions

I'm trying out some protocol code. Here's what I'm trying: (defprotocol AFirst (first [s])) this blows up with : (defprotocol AFirst (first [f])) Warning: protocol #'foo/AFirst is overwriting function first WARNING: first already refers to: #'clojure.core/first in namespace: foo, being replaced

Re: Shaping my game API

In a test game engine I developed, I simply used maps and created a sort of "duck" typing. It actually worked quite well. For instance, each entity would have a :physics-update function: ((:physics-update entity) entity timespan) It ended up working very well. I had a few thousand entities, all u

Hi, I'm at the moment writing a 2D game 'thing' (wouldn't call it a framework or engine really) I don't have it released yet, but when I do, I'll post it on this list. In my 'thing', I just do something like this for the game loop(pseudocode): (doseq [frame (iterate #(map act %) initial-state)]

Shaping my game API

Hey, I'm writing some Clojure game stuff, and I'm having trouble coming up with a sensible model for the game objects. The basic idea is that I have a bunch of objects that represent the game, and call 'act' on them, supplying the current world to get their next state. The objects have a few p

Yes. Generally push lazy-seq as high in the chain as you can (but no higher!), for that reason.. On Apr 3, 11:09 pm, Roman Sykora <4rt.f...@gmail.com> wrote: > Thank you for your time and kind answers. I really enjoy reading this > group and the whole clojure community. Enough flattery ;) > > A qu
