@RavenDreamer may I assume vecInput is storing your final result?

Raven Dreamer

Yes.

Gajet

side question, I thought you were working with unity, why do you have xna tag in your question?

Raven Dreamer

Because the question is not unity specific, and XNA has a higher follower count than C#

Gajet

then you should not add any of those tags to your question.

you can't add any tag to your question, unless it describes what the question is about.

Raven Dreamer

XNA uses C#. It does describe the question.

@RavenDreamer are the original angles always a cardinal direction?

if you want an anisotropic function that rescales a vector I'd do something like

scaledMagnitude = Sqrt((v.x / maxXSpeed)^2 + (v.y/maxYSpeed)^2);
if (scaledMagnitude > 2)
   v = v * 2 / scaledMagnitude;

You know what I hate... tutorials with horrible variable names.

Jimmy

variable names such as "v"? :P

tylerrrr07

foo bar, v, variableprefixRealVariableName, etc.

Gajet

4:18 AM

@tylerrrr07 then what do you use suggest for variable names?

tylerrrr07

@Gajet - I've got basic mouse input working now. One step closer to that RTS :P

Gajet

:D

tylerrrr07

I can click stuffs and select stuffs using a drag + click

Gajet

yesterday I've talked about same idea with a friend of mine,

tylerrrr07

And how about... DescriptiveVariableNameBasedOnWhatItsForWithoutAnyPrefix

Gajet

4:18 AM

@tylerrrr07 that's too long

anyway it seems he once had that idea and implemented a tech demo with gamemaker

tylerrrr07

@Gajet I'm speaking in generic terms. But in all honesty... if that's what it requires for me to figure out what the variable does, then its just long enough

But to be specific, the example I'm looking at prefixes all of its class level variables with the letter m

Gajet

though he got off the track after a little while and it ended up a game which you had to design some objects and their behaviour

tylerrrr07

Makes Copying / pasting / formatting to my specific needs a pain

Gajet

I like prefixes.

tylerrrr07

Prefixes are OK when it comes to UI - otherwise meh... I'd rather not

Gajet

4:21 AM

they usually declare variable scope. or variable type.

tylerrrr07

especially for something as trivial as scope

Gajet

I use "m" prefix for fields too

scopes are not that trivial.

specially when you class contains methods with 50+ lines of code

tylerrrr07

Fields and local scoped variables start with a lower case letter for me. Properties start with an upper case letter.

And thats sufficient for me

Gajet

this happens when you are developing core features

tylerrrr07

Yeahhhh... We're going to have to agree to disagree here

Gajet

4:23 AM

for me all Fields start with "m", all methods and local variables and functions start with lower case letter, and all classes start with upper case.

tylerrrr07

Methods and Classes both start with Upper Case for me

Jimmy

I don't have set naming rules but I probably use what tyler uses

tylerrrr07

If it isn't obvious which scope a certain field / local variable belongs to (class or local) then the class / method design probably isn't quite right

Jimmy

that's pretty close to .NET standard style

tylerrrr07

@Jimmy - That's pretty much where I got it :)

Jimmy

4:26 AM

fancy naming systems make it harder for me to understand code

might as well alternate between rEVERSEcAMELcASE and igPay atinLay.

William 'MindWorX' Mariager

I'll never understand or even remotely like web development. :(

tylerrrr07

@WilliamMindWorXMariager - What's not to understand?

Gajet

@WilliamMindWorXMariager it's not you, it' web developments problem :D

William 'MindWorX' Mariager

According to html5test.com, my phone supports canvas and 2d.

Running this in my browser: legeria.net/l2r

Works fine.

Running it on my phone.

White screen.

Now, I'm using firebug, to make sure there are no errors on the page. And there's not.

tylerrrr07

Blue BG + Green Box?

Is there more to it?

Jimmy

4:30 AM

looks fine in iPhone4

William 'MindWorX' Mariager

@tylerrrr07 Nope that's all.

tylerrrr07

Works on my Xperia Play

William 'MindWorX' Mariager

Only special part about the page is, it'll retain the same width/height no matter the resolution, as in, not scale.

I'm trying to test it on my Windows Phone 7.5.

Which, like I've mentioned, should support canvas with 2d context.

Gajet

windows phone is using IE core, which I doubt has a version more than 8

tylerrrr07

Well, bad news, it doesn't work on IE 9

Which also supports Canvas according to that site

William 'MindWorX' Mariager

4:32 AM

html5test.com/compare/browser/wp75.html

tylerrrr07

Maybe there is a specific implementation required for IE9

Jimmy

SCRIPT438: Object doesn't support property or method 'getContext'

oh wait

it's in quirksmode

tylerrrr07

@WilliamMindWorXMariager - Try including <!DOCTYPE html>

Jimmy

you have to doctype the demons out of that one

tylerrrr07

@Jimmy - I saw that

William 'MindWorX' Mariager

4:34 AM

Where should I place that? Top of the page?

tylerrrr07

Parsing rules 1
<!DOCTYPE html> triggers standards mode »

Yes - At the top

Jimmy

absolutely before anything else

William 'MindWorX' Mariager

Works. :D

tylerrrr07

Yay for wanna be game devs that are web developers IRL :P

William 'MindWorX' Mariager

Hehe

Next step is getting it to actually fill the page properly like it does in firefox.

So, should I test with IE9, and assume I get the same issues in it like I would on the phone?

I guess I could just download IE9 and test. :P

Anyways, I'll be back soon, you kids are awesome. <3's and huggles.

Windows Phone

Windows Phone is a mobile operating system developed by Microsoft, and is the successor to its Windows Mobile platform, although incompatible with it. Unlike its predecessor, it is primarily aimed at the consumer market rather than the enterprise market. It was launched in the second half of 2010, with a release in Asia following in early 2011. With Windows Phone, Microsoft created a new user interface, featuring its design language called Metro. Additionally, the software is integrated with third party services and Microsoft services, and sets minimum requirements for the hardware on w...

(Link goes to the web browser section)

Long story short - it uses IE Mobile with a rendering engine based on IE9 - so testing with IE9 first is probably a good idea but not a guarantee.

IE9 also has a developer toolbar built in that's similar to firebug (press F12) so you can use that for troubleshooting some.

William 'MindWorX' Mariager

Thanks @tylerrrr07

Right now I have a white bar in the bottom when in portrait mode, but not in landscape mode.

I guess I should see if I can detect portrait/landscape mode. :P

Since it doesn't fix the resolution right now.

William 'MindWorX' Mariager

5:57 AM

Yay

Basic rendering loop is working: legeria.net/l2r

All written in SharpKit. <3

Gajet

6:10 AM

@WilliamMindWorXMariager is it 6am your time?

William 'MindWorX' Mariager

Right now?

It's 8:10 AM

Gajet

yes

@Gajet - I may have an idea for an RTS

Kind of...

It's more like I have an idea which involves writing an RTS toolkit that allows you to create custom Tech Trees using Custom sprites / animations and then I'll make the game that uses them

dbomb101

12:32 PM

Hey guys

Gajet

@tylerrrr07 I'm listening

you mean I have to design the tech tree?

if that's the case, there is no need for any toolkit.

I can directly write all the tree into a file.

and you (or again me) can write a parser only to draw that tree.

tylerrrr07

1:02 PM

@Gajet - No I mean the players can design their own tech tree if they want

In my head I have a vision of notebook doodlings, stick figures with different themes (Pirates, Ninjas, Medieval, etc.) to start out with, and then a little wizard for creating their own and importing their own doodles as graphics

@dbomb101 - Hey

And then I thought it would be neat for online play where you could on the fly download the other players tech trees and use them kind of like a downloaded map

The tech tree building could have some sort of score system so that you can't just make a super OP tech tree (though without really thorough testing I imagine this could happen anyway)

This is just what my imagination came up with when I was trying to sleep last night

Gustavo Maciel

+1 for player customization :)

hey guys

do you mix TCP with UDP for example in FPS game, when there's need for e.g. chat messages ?

according to my question on SO:
http://stackoverflow.com/questions/11361208/high-performance-scalable-udp-servers

the man says that "Using TCP for chat messages and loading level data at startup looks like a good idea, that's an usage pattern TCP is good at."

and again here
http://gafferongames.com/networking-for-game-programmers/udp-vs-tcp/

though Glenn says that "My recommendation then is not only that you use UDP, but that you only use UDP. Don’t mix TCP and UDP, instead learn how to implement the specific pieces of TCP that you wish to use inside your own custom UDP based protocol."

Later in the comments he replies about mixing the protocols that "now, of course if you just had the occasional event sent via TCP, and the bulk of your time sensitive data in UDP, no problems at all"

or should I just ask separate question on this site ?

also, high five gustavo, I'm too 16
