NPCServer updates

[Admins]

Today the npcservers have been updated. Here some of the updates:

- /style works again
- improved /scripthelp which also lists object types that match
- fixed int(random(lowerlimit, upperlimit)) which sometimes reached upperlimit (when the random number was too close to the upperlimit it was rounding to upperlimit)
- scripts can now access image files (png, gif, jpeg) and also files inside the levels folder if the npcserver has the rights for that
- if you call a function of another object which is non-public, then it will display that the function is not accessible, instead of saying that the function doesn't exist
- graal script now supports function objects: this will print "param: 123"

PHP Code:

function onCreated() {
  this.func = this.func1;
  this.func(123);
}
function func1(param) {
  echo("param: " @ param);
} 


You can also do this, but keep care to add a semicolon behind the function declaration:

PHP Code:

this.func = function() {
  echo("nameless function");
}; 


This is only working on serverside, it will work on clientside with the next Graal version.
There is a protection against unsetting functions, since often scripts use the same name for functions and variables. If the variable is not linking to a function but the script contains a function with that name, then it will use the function defined in the script instead. You can however link to another function.

Very nice updates, Stefan.

Function objects!

What do they do? Sounds like fun.

Edit: The first one I understand as being able to assign a function name to a variable. Being able to add params to the functionname by calling the variable as the function and receiving it using the assigned function name to the variable.

Ah, tested out the later, the beauty of it is you don't need to actually receive the function. Now that is sexy.

Edit 2: There's only a few problems I'm having, like not being able to return information and work with objects inside the "embedded functions".

Nice Stefan.

/scripthelp text: print help for a server side function
/scriptscan weapons/npcs/classes/levels/all text: scan scripts

Very cool!

Very nice! I wanted function pointers for something a while ago... but now I can't remember what it was :P

[Switch]

Cool...

[JkWhoSaysNi]

now i remember! I wanted some OO functionality without using classes.
If I did this:

PHP Code:

public function increment() {
this.count++;
}

function onCreated() {
 x = new TStaticVar;
 x.increment = this.increment;
 x.count = 1;
 x.increment();  //x.count = 2?
} 


Will x.count get incremented when x.increment() is called or will count get incremented in the script which created x?

x.count will be incremented

So what about returning information through this, doesn't seem to work?

Not sure but something like this would probobly work:

PHP Code:

function func()
  return "Hi";

function onCreated()
{
t = new TStaticVar();
t = this.func;
echo(t);
} 


[Twinny]

Aww...printf() in loops problem wasn't fixed .

Yet another moment where GS2 has unlimited possibilities opened. Thanks Stefan, WHEEEEEEEE

Yeah, RW that returned func. So, I'm not sure. This seems to contain a few bugs as it were because it's new. But as far as returning information I had been doing things like.

PHP Code:

function onCreated()
{
  this.newObj = function() {
    echo("stuff");
  };
 
  this.newObj();
} 


And I have been trying to, for lack of a better word, reverse engineer that into something like.

PHP Code:

function onCreated()
{
  this.newObj = function() {
    return (1 + 2);
  };
 
  echo(this.newObj());
} 


And lol, whaddya know...it works that way, this has to be experiemented on a bit. As it returned the right thing just now. =o
