Re: 2D game engine written in D is in progress
Also do somebody know how should I speed up the sprite part of the code? In my opinion, it's pretty slow alrought it was the easiest way I could come up with. Hi, you have wrong approach to this problem. From design OOP view it is perfectly ok and this is how you universities teach it in their SQL classes... But you probably don't aim for clean OOP design but for speed. You work with every single sprite as entity. But you should aim to process sprites in batch. Your sprite should be probably struct, then feed array of them into separate function instead of calling on every sprite. Difference: foreach(sprite) sprite-doSth(); vs: doSth(sprite[]); this is good read: http://gameprogrammingpatterns.com/flyweight.html
Re: London D Programmers MeetUp
Thank you, Kingsley, for a very well organized and thought-through event. I was impressed by the calibre of people that attended, and look forward to attending future meetups.
Re: London D Programmers MeetUp
One interesting anecdote: somebody in a financial services company gave an account of giving D a try as a way to prototype something quickly, intending to rewrite it later in a more conventional language. The prototype went straight into production, and they are happy with it. The C interop was important for them to have made this possible. It was interesting, because it is a serious company where people don't by any means have a hacker mentality, and it was one more point at variance with the I am a java programmer but do all my personal projects in D narrative, and also because this particular kind of company is exactly the sort of second wave early adopter one wants to have. (I hope I represented this accurately, and tried to make this as vague as possible whilst still keeping it useful since people might not want the details of what they do being public).

Re: London D Programmers MeetUp
Thanks to everyone who attended it was a great evening of D fun :) As part of the evening we did a secret santa code challenge - here are some of the results: http://www.meetup.com/London-D-Programmers/messages/boards/thread/48694585 We had about 13 people from different backgrounds - many from C/C++ as well as Java, F# and dynamic languages such as Python. Many of the guys had a financial / banking background or an academic background - for example we had some guys working on market data, another guy who ran a hedge fun as well as people from scientific / research and university backgrounds. We touched on IDE's and editors for D - I demo'd my intellij plugin. Bruno was also there (he maintains the eclipse D plugin DDT) and he had some interesting things to say about where he thought the future of IDE's is going especially in terms of code completion. In my intellij plugin I actually re-use the guts of the DDT parser/lexer and the general opinion seemed to be that have a single set of tools that could be re-used in multiple IDE projects was a good way forward. I already implemented Brian's DCD and DScanner tools in my plugin and Bruno was looking to go that way also rather than re-writing the wheel each time. Brian certainly has some great tools in D for this kind of thing. (Hackerpilot - DCD/libdparse/DScanner etc) We also had some discussion about the popularity of D - and many felt that D was a great language especially coming from C/C++ but that the whole community was perhaps a little fragmented and finding information on the Dlang site was also a bit disjointed and that in order for a language to gain popularity it needed the appropriate community support and information - the recent language Rust was mentioned as having great documentation/support for new people and is arguably doing a better job at that aspect than D especially since its such a new language compared to D. There was also a bit of discussion around the dub package manager with Russel W feeling strongly that dub was more like a java maven and had many issues for what he wanted to do. I think he has since posted something on the D forum about his dub feelings. We got onto dub from my intellij plugin which uses dub by default. We got together in pairs with 1 more experienced D person and 1 newbie / less experienced D persons and paired on the secret santa challenge. We only had about 45 mins for this one and then some discussion on how we chose to implement things. A couple of issues came out of the challenge regarding familiarity with syntax and then spending time hunting down the docs - is there a forall in D? Also one of the guys ended up with an out of data d compiler and spend a lot of time trying to get the right version instead of the one that came with the IDE he downloaded. The slides for the evening are here: http://slides.com/kingsleyhendrickse/london-d-programmers Our kind host Skills Matter are organising a Functional Programming conference in the summer and they have suggested we add a D talk to it that focuses on the functional aspects of D. I'll be arranging meetups every 6 weeks or so.

Re: London D Programmers MeetUp
usually it applies to a collection e.g. List in Scala there is one - that takes a function that returns a boolean. e.g. List(1,2,3).forall(x = x 3) which is equivalent to a foldLeft ( I think) On Wednesday, 4 February 2015 at 14:52:32 UTC, Andrej Mitrovic wrote: On 2/4/15, Kingsley via Digitalmars-d-announce digitalmars-d-announce@puremagic.com wrote: A couple of issues came out of the challenge regarding familiarity with syntax and then spending time hunting down the docs - is there a forall in D?
