Game development in Clojure (with play-clj) 

Thanks for your comment, and I'm happy I was able to help clear up a few issues for you.

Hi Boris, I'm glad you enjoyed it. I've uploaded the project's core.clj to a GitHub gist (gist.github.com/Misophistful/9892203).

Misophistful Thanks , and I get a question about: spawn-apple function. I don't see it added to vector of entities. What I am missing? Thanks.

Boris Rozinov Spawned apples get added to the vector of entities in the :on-timer function (line 74). However, the name "spawn-apple" does imply that the function is doing the spawning (i.e. adding to the vector), so I see why you got confused. To improve this I could either rename the existing function to "create-apple", or keep the current name but change the function to receive the vector of entities as a parameter so that it could actually spawn an apple itself.

Misophistful Thanks a lot, now it is clear , I just missed 'conj' initially

It sounds like you might have an old graphics chip/card that doesn't support the version of OpenGL that libGDX requires. Without more details about your setup, I'm afraid the only advice I can give you is to make sure that your graphics drivers are up-to-date. Good luck!

Misophistful Well, although I have instaled brand new drivers for my card, at the moment I still got the error message. But when I have reinstaled my pc, it works flawlessly. Reinstaling was the key. Thanks, and yes, nice video, I am creating a game also, and this video is very helpful :)

tintinexplorerbg I'm really glad that you got it working, and that you found my video useful. Good luck creating your game!
