What I want to do is create a game like an old DOS game, but on the debian linux console. I don't know much about linux yet, but I know C. What would be the best library for doing something like this?
View 8 RepliesDo you know any game engines or game studios that can make adventure games, for instance in the style of Myst (1st person) or in the style of old Sierra games (3rd person), like King's Quest, Space Quest, etc.?I've seen AGI Studio, but it is too old, I'd like to use more modern graphics (although there is no need for 3D).
View 7 Replies View RelatedI've been working on this console-based game (in c) in which the player walks around touches floating orbs which do things etc. And I want to make it so that an object on the map blocks the sight of the player, which is something I haven't tried until now. This is the part of the code which handles this sort of thing :
void uncover(int shadow)
{
int wp,
hp,
xp,
yp,
pp, // point placement
mp, // maximum pp value // (that's what she said)
lp; // light placement .....
This <works> but isn't very nice. What I would like to do is to change the third to last if statement, which is really more of a geometry problem, which could be frased as :
given points (x,y) , (plist[pp].x,plist[pp].y) and (wp,hp) create a conditional which tests weather or not point (wp,hp) is within the shadow cast by light-source (x,y) being blocked by an object at (plist[pp].x,plist[pp].y), [with some width, ~1]
but there isn't a geometry forum, and it's somewhat more related to programming.
I have all of the code written for a text based game but how big of a leap is it from text to graphics? lets just say a 2d engine. Is this a fairly easy task or would it be a bit of effort? I've never done anything with graphics before and would just like a quick idea of how much of a project is graphics vs functionality.

View 1 Replies View RelatedMy hardware is the FriendlyArm mini2440 Samsung board. I run our main application from init.d/rcS. It uses printf's to display continuous program debug information that can be seen on the serial ttySAC2 console. I would like to be able to remotely view this information by a telnet connection when needed. What is the best way to accomplish this? The telnet user can possibly activate some script or program. I saw there is a ttysnoop program that I could not get to compile.
There must be a simpler way. There must be several ways. Instead of using printf I could do something else. I do not want to use a normal log file to the flash file system. I had thought of using a ram file in /var directory but it would complicate matters as I would need to limit its size and the telnet user needs to view the program's printfs in a real time fashion.

I'm trying to write a simple, console based application in linux, in c++. I know how to start in Eclipse and I have some experience in c++ from Windoze.

But what I like to do now is to write stuff onto the console, and I don't get it. According to my tutorials I can print stuff on the console using the printk()-function as long as the priority-level of the macro used in printk() is lower than the console_loglevel (how can I find that value out btw?).
But it doesn't work for me. Even if I use KERN_EMERG it still gets only logged, but not printed on the console and I thought KERN_EMERG get always printed...

View 1 Replies View RelatedI use ioctl to get the console window size (the SSH window). I use the following code:
struct winsize ws;
int returnValue = ioctl(pCommandStructure->terminal, TIOCGWINSZ, &ws);
int numberOfColumnsOfTerminalWindow = ws.ws_col;
When I debug on linux pc, it gives me the correct window width. But after I try it on router (this is my enventual place where my code shall run), ioctl always give me 0 width, that is, numberOfColumnsOfTerminalWindow == 0. but the returnValue is 0 which means that the function call succeeds.
How system call internals could be known ? I mean for example if i take the example of write system call of linux kernel, where i can find out the code of write() system call in the kernel source tree ? The problem is write() system call directly write on console.If we want to write the data on some web page then write() system call will not do that ? How to redirect out data from console to application like html/web page?
View 6 Replies View RelatedI am interested in learning 3D programming. The thing is, I would hate to put too much effort to learn something that doesn't have future and is dying. My favorite language at the time is Java. My goal is professional programming.
So I have several questions:
1. Should I learn JOGL or start learning C++ and do C++ openGL programming?
2. Is there a big difference between JOGL and C++ openGL programming?
3. Is it worth to learn openGL? Does it have a future?
4. Is it a big difference between openGL and directX coding?
5. If choosing Java, then JOGL or LWJGL?
Why and what is the main difference between them?

This game is Java based. After rebooting the game works, but on ending the game several notification boxes remain. If these boxes are not closed in the reverse order that the game opened them, it is no longer possible to close them. Only by killing the Java processes can these notifications be made to close. Also after playing the game, even if all these notifications are closed it is many times necessary to kill the Java process(es) in order to get the game to load again at a later time. I am currently using Slackware 1.30, but a similar problem has existed in several of the past releases.

A simple TCP based chat server could allow users to use any TCP client (telnet, for example) to communicate with each other. For this question you should consider a single process, single thread server that can support exactly 2 clients at once, the server simply forwards whatever is sent from one client to the other (in both directions). Your server must not insist on any specific ordering of messages as soon as something is sent from one client it is immediately forwarded to the other client. As soon as either client terminates the connection the server can exit

[Code]...
I need to know what, for example, 'ttable' means and what is its syntax. This seems to be a state secret.
We have documents on multiple workstations and want to collate them into a single repository to provide text search and download. So far we have implemented rsync to copy files from each workstation under a directory for each workstation on a server (incidentally providing a backup) and have set up text search using Xapian with Omega; users access it via a web browser. Still to do is to set up a system to copy files from each workstation's area on the server to the repository.
Many files are duplicated. In these cases we want to preserve the names but keep a single copy of the file;hard links can be used for that.For each file to be copied from a workstation's area into the collated area we need to check whether it is a duplicate (file size and, if same, MD5 sum) and if so, create a hard link to the original rather than create a copy.A system to detect and replace duplicates in the collated area has been written using ruby and postgresql but the developer cannot commit to continuing this work. It does mean we have a postgresql database populated with "fingerprints" of files in the collated area.My first priority is to get the system working; in the longer term whatever is developed must be maintainable; I do not yet know which language skills are available locally.
I am fluent in bash and competent with awk. Ruby looks nice but I have started to learn python and do think it prudent to learn both at the same time. Python's postgresql capabilities are not settled but may be fine for the simple usage required.What to do? A bash solution would run very slowly but could be developed quickly. Language knowledge aside, I have found it difficult to install ruby on the server (CentOS 5.5;installed rvm but "gem" still not installed; seems a very complex system with its own package management).
