Problem with Overloaded Equality Operator

PresCoke — Sat, 21 Nov 2009 19:56:39 GMT

As you can tell from the title I'm trying to build an overloaded equality operator to see when two objects are equal, however it doesn't seem to work, so I was hoping one of you fine people could point out the problem to me.

here's the code, not: m_speed, m_altitude, m_bearing, m_start are integers; m_x and m_y are floats; and m_name is a character array.

bool FlightPlan:perator==(const FlightPlan &other)
{
fprintf (stderr, "Equality Operator runs to #1\n");
if (other.m_speed==m_speed && other.m_bearing==m_bearing && other.m_altitude==m_altitude && other.m_start==m_start && other.m_x==m_x && other.m_y==m_y)
{//control#1: to check Flight I.D.
fprintf (stderr, "Equality Operator runs to #2\n");
if (strlen(m_name)!=strlen(other.m_name) || m_name==0 || other.m_name==0)//if not the same length or either is NULL, not equal
return false;
fprintf (stderr, "Equality Operator runs to #3\n");
for (int i=0; strlen(m_name); i++)
if (m_name[i]!=other.m_name[i])//if unique characters exist, not equal
return false;
fprintf (stderr, "Equality Operator runs to #4\n");
return true;//if it passes all other tests then objects, equal
}//end control#1
else
return false;
}

Here's the relevant stderr output:
Equality Operator runs to #1

The program has unexpectedly finished.

Thanks,
James

C++ Learning

YourAngel — Sun, 31 Aug 2008 19:58:22 GMT

Hello

My name is Andy, and i'm a 13 year old Swedish... Teen.

A while now, i've been looking away from my usual modding to take a look at C++ which nowadays is a MUST in the game industry apparently. So for the past two days i've been reading through the awful http://en.wikibooks.org/wiki/C%2B%2B_Programming/TOC1 C++ Wiki Book. I really started thinking it was supposed to be that hard to learn CPP programming. But a friend told me that Wiki Books are usually overly difficult, at this point i jumped around in happiness thinking that there might still be some way for me to learn it.

So right now i'm looking at http://www.dummies.com/WileyCDA/DummiesTitle/C-For-Dummies-5th-Edition.productCd-0764568523,subcat-PROGRAMMING.html this. The description there says that the CD will cover everything other than the guidance from the book. However, in my experience, you would need mathematical skills in stuff like algebra, trignomethry etc etc to work with CPP.

I would persistantly motivate my dad to let me buy that book, but i don't want to spend money on something i wouldn't understand for several years yét. So is it possible for me to actually learn CPP without a super high maths-certificate?

And my other question... I've seen different feedback on that book, is it really user-friendly? Despite being 13 years old i am not an idiot, i can pick up difficult things, but that Wiki Book was just way beyond me, is this book going to be same?'

Thanks for any answers!

Programmer needed to help with Dungeon Keeper2

hubutton — Sun, 29 Mar 2009 19:59:48 GMT

Hello

I bet some of you have heard about the Dungeon Keeper games, in my opinion the best game serie(ok he didn't work with DK2) created Peter Molyneux.

Im part of the last active DK community, and since none of us in the community knows nothing about programming, I decided this could be the best place to start looking for help to our problem.

I will go straight to the point, and assume you know what Im talking about:

DK2 editor is clearly unfinished, because you cannot make working mercenary portals with it. There seems to be some variables that make the portals work, but it is not possible to change those with the editor, since Bullfrog forgot/didn't bother to add that function.

Im looking for someone that could either upgrade the editor and add that function, or atleast tell how it could be done or can it even be done.

Programmers, how did You get started?

Rectov — Sat, 25 Apr 2009 21:09:41 GMT

Hi there, I'm really struggling to get to grips with programming. I don't know if it's the resources I'm using, or if I'm just too thick to get to grips with it. I have read the thread about how to get started which recommends Java then C then C++ route. I can see the wisdom but even with Java I face the same problem, that every tutorial seems to demand I become conversant in about ten-billion different things before I can even contemplate doing anything interesting.

I just want to begin playing with graphics and take it from there. Is there any hope? : )

Whilst I'm bitching, I'm always hitting that same wall I've heard other people talk about that means it can takes hours to learn what feels like nothing. I think this is because of the number of tutorials that aim to teach a language outside of any particular kind of programming discipline. Isn't there a book called "Learning to program C++ in the context of learning how to write games in the context of the commercially available programs that real developers use"? Which progresses in a first you learn to get a screen, then plot point, draw lines, make polygons, animate characters, double and triple buffers, etc. Instead of all this pony about writing a GUI for Windows using windows widgets, which nobody in their right mind would want to do!

General Tools and tutorials needed to make A game?

rockhopperseanly — Tue, 15 Sep 2009 15:19:27 GMT

And if so, what tutorials would you recomend? To make a simple game?

And if your bored, Why not help me make it.

website development questions

kev670 — Wed, 08 Jul 2009 17:46:31 GMT

I have 2 questions.
I usually build static websites but i have been asked to make a website for an owner of a bar. They want to be able to update an events page regularly. What ways would you recommend for me to implement this. I'd rather not use a google calendar. Is there any way of being able to write short messages on the site without having to go through the code

Secondly, How much is a reasonable price to charge for a fully function website.

Any help would be great thanks

Programming and its Connection to Math

PCRYJ — Wed, 28 May 2008 01:17:34 GMT

I'm a fairly new programmer(C++), and I have had a few questions about programming as it becomes more complicated and complex that I never seemed to find the answer to. Do you have to be at math to be a programmer? I'm asking this because I am concerned at the fact that I'm not exactly at math(English is more of my thing), but so far I am enjoying programming at a simple level. Also, as programming becomes more complex, meaning development level of AAA games (Fable 2), what type of math is invloved? Can you get by with just a simple understanding of certain math topics?

- If anyone from the community or hopefully someone from Lionhead, could answer any of these questions for me, or just give me some suggestions, that would be greatly appreciated!

Programming basics.

Ash692 — Mon, 31 Aug 2009 08:39:07 GMT

Hey Everyone,

Haven't been on this sub section before, but I feel it's the right time with college in a week.

I'm studying IT for 2 years at college, the curriculum is really really detailed. I'll be doing programming,designing,website design,softwarfare designing, game dev, so lots.

I was wondering if anyone knew of any free programmes on where I can maybe catch up on some basics of programming (C++,C)

It would be incredibly helpful because I could learn from it before college and in my free time.

Thanks

~Ash

Tools Used For Fable

What tools were used to make Fable other than the unobtainable FableEd? Does anyone know? Can anyone provide links?

What events happen in a programmers day to day life?

automission — Tue, 02 Jun 2009 09:02:55 GMT

Is it as simple as knowing how to code, sitting down and typing lines and lines of code out? That alone sounds complex to me, but I assume once you know how to code, it is a easy as speaking your native language?

I ask as I often ponder taking courses in programming, but I'm still quite unsure on it. Hell i need to know coding to get into testing, so I'l need to learn coding regardless.

Is programming for me?

Elite3van — Fri, 21 Aug 2009 18:04:08 GMT

I have recently been thinking about my life after school. I am currently 13 and have a passion for games. I'm smart (I think). I'm top in my maths class, science class and IT class, and I am a musician for my county. I really want to become a programmer, but is it too hard/ambitious for me. I have tried Visual Basic but it looked sooo complicated I gave up. Here's my rough plan for the future.

GCSE:
Including
Maths
Further Maths
Triple Science
I.C.T
Music

AS Levels:
Music (Or further maths if there is that)
Physics
Maths
I.C.T

A Levels:
Physics
Maths
I.C.T

Uni:
Maths
Computer Science (preferably with a year in industry)

I was thinking I could go Lionhead for work experience and their graduate program thing.

But is programming for me? I've also heard that it really sucks. I am, to quote, in a kerfuffle!!!

Please can you give me all of your advice!!!

New to programming, thinking about taking some classes and more

Michigan52 — Sat, 01 Aug 2009 02:52:11 GMT

Hey guys im pretty new to programming like the past week or so new and im learning the basics of HTML and C++. I started looking into it because i love video games and was trying to think what i could do to get into the field of making them. I was just wondering what people think of as a way to get started like things to read or things to work on. I am still in highschool and my school offers a few classes in programming. Not many but a few. I was thinking about getting a couple books and taking the classes seeing if i enjoy it/understand it. Im also pretty at art so i was thinking more down the line of graphics programming. I was also wondering if were to enjoy/understand it then what would people with more expeirence or jobs in the field think i would want to take major in in college.

Thanks for the help guys

How do Achievements work?

Fata1moose — Sun, 29 Mar 2009 20:33:23 GMT

Somthing always wanted to know how do developers make them work how does the game know when you got one? pretty much just the general basis behind it.

The windows communication foundation is a nightmare!

Pandilex2 — Sat, 18 Jul 2009 17:43:04 GMT

I spent a long time with sockets in C#, a very very long time indeed. They were poorly documented and caused me no end of grief with bizarre quirks and such.

I finally decided to make the move to the WCF to see if I it was easier to get along with, but I have found it to be a nightmare so far... there is also a laughable amount of documentation and tutorials available for it, so I was wondering if anyone has had any success with it.

All I want to do is have a server, and a client, making a tcp connection and sending data back and forth.

After a huge amount of struggling on my own, I gave up and bought a c# book that covers it in one chapter. I followed the tutorial and made a simple http based server/client. I then tried to adapt it to using tcp, and now svcutil can't generate me a client because "the connection was closed by the remote host". The same thing worked fine before I switched it over to tcp...

It's driving me nuts, I have been trying to get it working for 3 days now and it's all trial and error... does anyone have any advice?

learn iphone programming

mobil1 — Fri, 19 Jun 2009 11:55:34 GMT

thought i'd let you know of an online iPhone Course that teaches aspiring students via video, pdf and one-on-one lessons. Its not that expensive ($200) and there is a $50 rebate if you use the code AZV while registering.

You also get to work and co-publish your first live industrial iphone project (game or application) on the official Apple Appstore, and you get to keep 80% of the revenues as part of a co-publishing deal with the company that runs the online iPhone classes. This means that you can essentially earn back the money and time that you put into this, many times over in a matter of a few months!

Interested people will need to register ASAP, as they are quickly approaching maximum capacity and will not be able to entertain an excessive number of students. Visit the link - learn iphone tutorials to sign up today!

Where Do I Start?

ArrowGoBooom — Sat, 30 May 2009 19:41:05 GMT

Hi,

I am a graduate who is interested in the game programming field. I would eventually like to work for Lionhead Studios on Fable 3 but, need advice on where i should start. I have some knowledge of c/c++(very little), java, flash, html, css and javascript(graduate related - 7 month course). What would i need to learn in order to work at Lionhead Studios more c/c++ or another programming language?

Sincerely,

ArrowGoBooom

P.S. I have a website where i am doing a remake of pong for the Atari 2600 using 6502 assembly language, but it is currently down. The url is http://6502pong.110mb.com, and i hope to have it up very soon. Also i briefly looked at Alice 2.0 but was put off by it being a point and click language and not a hardcore code wise language.

Age-old 2D games programming problem. Are you smart enough to solve it?

Rectov — Thu, 16 Apr 2009 19:55:10 GMT

Hi there,

I wanted help solving a technical problem a friend has given to me. In fact, both me and my friend have our own solutions but we don't like them because we both feel certain there must be a better, more efficient way than how we're doing it.

The basis is simple: Given a specific speed, how do you get from A to B in 2D?

The exact scenario is typical of zillions of games. An alien baddy wants to shoot you with a missile he can point. We're not worried about the graphics here at all, only the path the missile will take. Assume the screen refreshes at 60Hz (which it does) and out game will sync. We have a fixed speed for the missile of V pixels/frame. My friend is using an integer V, but I'd think you might like to have a fixed point. The speed can vary from bullet to bullet, but it's constant once the bullet is fired. Simple so far?

Now both my friend and I have bothered to come up with answers of out own to this question and both of like neither of our answers. His is not realistic enough and mine is more realistic but too math heavy. His basically works out along which axis the bullet will travel fastest and makes the bullet travel at SPEED pixels per frame in that axis. After dividing to find the ratio of X to Y he then uses a variant of Bresenhams algorithm to calculate the speed in the Other axis (i.e. Substracting the fraction away from the start distance once per frame (and storing the answer for next time) until the subtraction underflows, then adding back on the length you first thought of).

The trouble with this is that all bullets always travel at SPEED pixels/frame in one or the other aixs, meaning the more diagonal the bullet direction, the more unnaturally fast the bullets move. In other words, if we fired a wide shot at a wall, the bullets would all hit the wall at the same time.... they should hit the closer part of the wall first. Get it?

My version also sucks. I get the exact right result, mathmatically speaking, but I'm using trig to get it, which includes a square root and two divides per missle shot. This takes ACRES of CPU time and the solution was discarded without implementation for being too CPU intensive. I agree. This is an answer but not a Result!

Can you *please* think of a better solution?

How important is math and/or what topics do I need to learn. ( GCSE Student)

xchris92x — Tue, 24 Feb 2009 00:52:47 GMT

I felt I needed to get this information before it is too late. How important is maths when it comes to programming I usually range from a mid/ high c. Should I just forget about or is it possible to be a programmer being an average maths student.

Also what topics would I need to learn or are there any programming tutorials that may come in handy.

Chris.
