Link to a pastebin: here Hmmm... if that mangled the diff file too much, PM me your email address, virusman, and I'll send the original. I'd post the text here, but it's 35 KB. |

Now that I've got item properties working, I've begun work on a workaround to the ActionDoCommand, AssignCommand, and DelayCommand problems. I believe I may have a fix, that only requires three small scripts to be loaded into the module, and one Relatively short ruby source file that overrides the NWScript module's definitions for those commands.
If it all goes as planned, this will be one less thing to be concerned over... and the Talent functions are unimportant to me... at least for now. |

Okay... I'm certain that my action type workarounds are working perfectly, so here's the source code:
| Code: | // relay_action.nss
#include "nwnx_ruby"
void main() {
object oMod = GetModule();
string sCmd = IntToString(GetLocalInt(oMod,"RELAY_CMD"));
ActionDoCommand(RubyEvalVoid("ActionSingleton.ExecCommand("+sCmd+")"));
DeleteLocalInt(oMod,"RELAY_CMD");
} |
| Code: | // relay_assign.nss
#include "nwnx_ruby"
void main() {
object oMod = GetModule();
object oRelay = GetLocalObject(oMod,"RELAY_OBJECT");
string sCmd = IntToString(GetLocalInt(oMod,"RELAY_CMD"));
AssignCommand(oRelay,RubyEvalVoid("ActionSingleton.ExecCommand("+sCmd+")"));
DeleteLocalObject(oMod,"RELAY_OBJECT");
DeleteLocalInt(oMod,"RELAY_CMD");
} |
| Code: | // relay_delay.nss
#include "nwnx_ruby"
void main() {
object oMod = GetModule();
float fDelay = GetLocalFloat(oMod,"RELAY_DELAY");
string sCmd = IntToString(GetLocalInt(oMod,"RELAY_CMD"));
DelayCommand(fDelay,RubyEvalVoid("ActionSingleton.ExecCommand("+sCmd+")"));
DeleteLocalFloat(oMod,"RELAY_DELAY");
DeleteLocalInt(oMod,"RELAY_CMD");
} |
Here's the code for RubyEvalVoid, which you can, and probably ought to update with an exception catching system:
| Code: | void RubyEvalVoid(string sCode) {
object oMod = GetModule();
SetLocalString(oMod,"NWNX!RUBY!EVAL",sCode);
} |
And now the ruby interface file. This file or code should be loaded in your preload ruby script, or during OnModuleLoad. At the very least it needs to be run before you ever use one of the three action based commands.
| Code: | module ActionSingleton
def ActionSingleton.Store(action)
@cmds = Hash.new unless @cmds
unless @cmdnext
@cmdnext = 1
else
@cmdnext += 1
end
@cmds[@cmdnext] = action
@cmdnext
end
def ActionSingleton.ExecCommand(idx)
cmd = @cmds[idx]
if cmd.is_a? Proc then
cmd.call
end
@cmds[idx] = nil
end
end
module NWScript
def NWScript.AssignCommand(obj, &action)
cmd = ActionSingleton.Store(action)
mod = NWScript.GetModule()
NWScript.SetLocalObject(mod,"RELAY_OBJECT",obj)
NWScript.SetLocalInt(mod,"RELAY_CMD",cmd)
NWScript.ExecuteScript("relay_assign",$OBJECT_SELF)
end
def NWScript.ActionDoCommand(&action)
cmd = ActionSingleton.Store(action)
mod = NWScript.GetModule()
NWScript.SetLocalInt(mod,"RELAY_CMD",cmd)
NWScript.ExecuteScript("relay_action",$OBJECT_SELF)
end
def NWScript.DelayCommand(t, &action)
cmd = ActionSingleton.Store(action)
mod = NWScript.GetModule()
NWScript.SetLocalFloat(mod,"RELAY_DELAY",t)
NWScript.SetLocalInt(mod,"RELAY_CMD",cmd)
NWScript.ExecuteScript("relay_delay",$OBJECT_SELF)
end
end
|
You can call the functions as follows:
| Code: | NWScript.DelayCommand(10.0) {
// code to delay 10 seconds.
}
NWScript.AssignCommand(oCreature) {
// code to execute with oCreature as $OBJECT_SELF.
}
NWScript.ActionDoCommand {
// Code to execute as a command in $OBJECT_SELF's action queue.
} |
You can, to my knowledge, nest the commands as much as you want. |

| Nice one! Any idea what the performance is like? Well whatever - this is a great development whether it's 100% optimal or not. |

| As I have described here, I am using a very similar approach with roe. Properly done, performance impact is negligible. |

| Yeah, unless you're calling a large number of action commands one after another, the performance impact shouldn't be noticeable. If you need to assign lots of commands to a single object, just do it once and put all of the commands within a single 'do || end' or { } block in ruby. Both my method and elven's method are practically identical, so which one you use shouldn't make any difference either. |

Hint: elven's nwn-lib is a complete replacement for LetoScript. 
Combined with NWNX Ruby, it's 100 times more powerful tool than NWNX-Leto. |

I can't compile the ruby plugin - all times i try i get an error...
| Code: |
g++ -w -fPIC -shared -W -Wall -o nwnx_ruby.so FunctionHooks.o ruby_int.o NWNXRuby.o plugin-ruby.o -lruby1.8 -DHAVE_CONFIG_H
/usr/lib/gcc/i586-suse-linux/4.1.0/../../../../i586-suse-linux/bin/ld: cannot find -lruby1.8
collect2: ld returned 1 exit status
make: *** [nwnx_ruby.so] Error 1
...
ruby -v
ruby 1.8.4 (2005-12-24) [i586-linux]
|
Can you see what i'm making wrong? I'm Running Suse 10.3 on my Root-Server...

| Some distros name the shared library without the version number. Try -lruby. |

damn - that's the reason 
Ruby now compiles without any errors...

Another day - another error...
After activating the nwnx_ruby plugin i get a segmentation fault error. I have set the correct path to roe in nwnx2.ini
| Code: |
[ruby]
preload=/home/nwn/svn/roe/preload_wrap.rb
|
nwn is located in /home/nwn
Have i missed something? Currently i have disabled the plugin upon i know how to solve this error...

| Any exception thrown in preloadable ruby code will segfault the server. With the roe wrapper script, the only line that is not wrapped inside begin/rescue is the rubygems require. If I had to hazard a guess, I'd say you do not have rubygems installed. |

Also: Plase note that I am not working actively on roe at the moment. roe is workable, if I recall correctly, but the API is still incomplete and it will probably have a few bugs of varying severity.
The little time I have for NWN, I put into nwnx_ice and kobold (but that does not mean that roe is abandoned). I found the roe drb approach to be lacking in performance with certain usecases. YMMV. |

While i currently not using ruby yet and i only want to make some expirience with it, do you think i should switch to nwnx ice? Kobold? Whats this - are there any documentations?
