Klicking an a Purebasic Program in KDE

Brujah · Post by **Brujah** » Fri Aug 12, 2005 12:08 am

Hy Purebasic Fans,

I want to achieve that when you Klick on my Program File in KDE my game is executed.

Brujah · Post by **Brujah** » Fri Aug 12, 2005 12:18 am

The game runs, but it can't find the other resource files (like my graphics).

Can I read out the path that I got called from?
I have to set this path I think.
And right now I have no idea how to do that.

I'm not sure if this would work for you but I use it when I need something out of the environment. Reading 'PWD' gives you the current directory...

BTW: I did not write this code, it is a little to dark for me just yet...

Code: Select all

Procedure.s GetEnv(Variable$)

  Protected *Environ.LONG

  !extrn _environ
  !mov eax, [_environ]
  !mov [esp+4], eax

  Variable$ + "="

  While *Environ\l <> 0
    If CompareMemoryString(@Variable$, *Environ\l, 0, Len(Variable$)) = 0
      ProcedureReturn PeekS(*Environ\l + Len(Variable$))
    EndIf
    *Environ + 4
  Wend

  ProcedureReturn ""

EndProcedure

MessageRequester("test",GetEnv("PWD"))

You can also use getenv() from the libc, which is probably a bit cleaner:

Code: Select all

Procedure.s GetEnv(Variable$)
  *result = getenv_(Variable$)
  If *result
    ProcedureReturn PeekS(*result)
  Else
    ProcedureReturn ""
  EndIf
EndProcedure

Yes, much cleaner!

Thanx a lot.
I integerated this routine and when I call my program from
the Commandline its working fine.

But when I click on the File in KDE it seems that thiy Environment Variable "PWD" is not set.

Is there another way to get a KDE Environment Variable?

I solved the problem in a different way.
I succeeded in creating a rpm for my game.
Now its working fine. Even with a Icon on the Desktop after installation!

Maybe its useful to anyone.
Here comes the spec that I created for my game.
You create the rpm with it using the command "rpmbuild -ba laby2.spec"

I translated it to 3 languages.

Code: Select all

%define name    laby
%define version 0.9.9
%define release 0

Name:           %{name}
Summary:      Lost Labyrinth is a so-called "roguelike" roleplaying computer game

Cool!

But how did you solve the current working directory thing?

The "GetEnv("PWD")" code only works when the app is launched from a shell (has it should, because PWD *is* a shell command)...

Brujah · Post by **Brujah** » Sun Aug 21, 2005 12:23 am

There is a Script "laby" created in /usr/games which changes into the right directory and executes the game.

So you can call the game by typing laby.

And you get a Link in your Start Menu. Should be enough to call the game easily now.

Post by **freak** » Sun Aug 21, 2005 12:33 am

Num3: PWD is not a command, it is a environment variable, that is set by the shell.
Thats the reason why it only works there

Anyway i really like lost labirint, i play it all the time :roll:

But there seems to be a problem with loading saved games, it always gives me "tempered error" even if i don't touch it!

Brujah · Post by **Brujah** » Mon Aug 22, 2005 12:59 am

So you use the windows version!
I have no idea about this.

Right now my version exists only for linux and I got multiplayer mode too!

Num3 · Post by **Num3** » Thu Aug 25, 2005 9:18 am

Can you fix the loading routines for windows?

I got to level 19, died, and when i tried to reload the previous level i always get the error...
