disableselectweapons and showstats are clientside only functions. They affect the player only. It looks like you need to run the code clientside. Put //#CLIENTSIDE at the top of your scripts.

The callstack overrun happens when your script is executing too many functions too quickly. It'll probably go away if you switch the script over to clientside. (I bet you have a 0.05 timeout, which is too much for the server to handle).

Timeouts faster than a tenth of a second are automagically changed to .1 on serverside.

And yeah, I didn't think about the fact that //#CLIENTSIDE isn't required in the level editor for clientside scripts. Good catch.

Inserting //#CLIENTSIDE at the top seems to have removed the errors. Thanks. But now won't my player's stats be vulnerable to cheap string editng kiddies? :P

You know, now that I think of it, it's requesting the script from the server when you call join(), which results in a small delay.

So, yea. It's easiest just to do all joins serverside.

[xXziroXx]

Jerret, you're actually missing something.

It's not being updated on clientside when you join it clientsided, true. But it's also not updated clientsided if you join it serversided. Note that sometimes both works, sometimes they don't - and when it doesn't work, it's updated if you reconnect with your client.

This is why I never "release" an updated clientsided class before manually reconnecting all current clients to ensure that they all got the update.

Ok, maybe I should ask this differently.. I wrote these scripts in GS1, but now I want to put them on my server, so can they be converted to GS2 easier with syntax changes? Or do I have to re-write them entirely?

You might get away with just putting the GS1 script up, but it's good practice to use only GS2 online.

You can mostly go line-by-line and make a direct change from GS1->GS2.

If you haven't checked it out already:
http://wiki.graal.net/index.php/Creation/Dev/GS1_To_GS2

That article gives a pretty good overview of the types of changes you need to make.

Ok, well for displaying showtext I presume this is the GS2 equivalent of what I have done for my hud.

PHP Code:

function onCreated() {
  temp.p = {5, 5};
  
  temp.txt = "HP:" @ clientr.player_hp @ "/" @ clientr.player_hpmax;
  temp.i = showtext(200, temp.p[0], temp.p[1], "Arial", "b", temp.txt);
  temp.i.layer = 4;

  temp.txt = "MP:" @ clientr.player_mp @ "/" @ clientr.player_mpmax;
  temp.i = showtext(201, temp.p[0], temp.p[1] + 20, "Arial", "b", temp.txt);
  temp.i.layer = 4;
} 


As far as I can tell, this works the same, but I don't understand "temp.p" and "temp.i", "temp.i.layer". I presume temp.i.layer is the same as changeimgvis, but what I don't understand is why the text being on layer 4 works, when I thought only 5 and up works for the screen instead of the playing field?

This script is something another scripter made/posted on my RC and I'm trying to learn off it and/or convert it to match what I have done in GS1, since it seems nearly identical but with strange syntax differences.

This really confuses me as to why everyone says "GS2 is easier to understand" or "GS2 makes more sense" because GS1 makes sense to me, but looking at this stuff, I am like.. what?!

Ok, so I have inserted my baddy script into a class, if I wanted to place baddies on the map with the baddie class as their script, would I be able to do something like a weapon with a trigger and some sort of putnpc script referencing back to the class? How would I do that serverside? I want the baddie to be seen the same by all players... would putnpc work with a class?

What?

Any specific reason? Functionally is bad? Or some "purist" idealism?

Not sure exactly, but Stefan said at several times not to, so that suggests to me that perhaps he checks what the script is in and decides how to parse it or something like that could be added later.

And yeah, GS1 just uglifies a beautiful script. GS2 is also considerably more efficient than GS1.

So basically, it's not needed to join a class?

Haha yes, correct.

I thought anything behind // isn't read by the system, so how does tagging //serverside produce a difference in the code?

It doesn't, the only time the parser reads anything that starts with "//" is when it is //#CLIENTSIDE. The ones I placed after the join were just labels.

You should always use putnpc2 now anyway; just put the code in a class rather than a text file.

Only if you used 'client.' vars. You should always use clientr (or serverside player. vars) for storing sensitive information.

If you want them to be dynamic (randomly placed), you should use a database NPC with something like the following

PHP Code:

function onCreated() {
  // init vars
  this.mapSize = {3, 3}; // width, height in levels
  this.classesToDrop = {"baddy"};
  
  onTimeOut();
}
function onTimeOut() {
  temp.tries = 0;
  
  while (tries < 5 ) {
    temp.dpos = {random(0, this.mapSize[0] * 64), random(0, this.mapSize[1] * 64)};
    
    if (! onwall2(dpos[0] - 3, dpos[1] - 3, 6, 6)) {
      // should improve the above checks, it's just an example.
      temp.classToJoin = this.classesToDrop[int(random(0, this.classesToDrop.size()))];
      
      temp.drop = putnpc2(dpos[0], dpos[1], "");
      drop.join(classToJoin);
    }
    tries ++;
  }
  
  setTimer(360); // could also add a way to check how many baddies there are.
} 


Otherwise, if you want them in static locations, just make a level NPC (with level editor) with this:

PHP Code:

join("baddy"); // or the other class

Ok, I used clientr. not sure why, but that's what I saw everyone else using so I thought it appropriate to follow suit, what is the difference between clientr. and player. ?

I will have to lookup putnpc2 since I have never used it.

Also, if I wanted to do something like a toggle, say:

PHP Code:

if (keypressed){
   if (strequals()){
      if (showimgIsAlreadyShown){
         hideimg;
      } else {
         showimg;
      }
   }
} 


How would I detect if said image is shown already?

clientr. can only be changed serverside, so you'll have to change your existing code. clientr. vars can be read clientside, though.

player.vars can be added serverside or clientside (and changed), but there are some disadvantages (and advantages).

For serverside, you can add a player.var. This is not synchronized with clientside. For example, "player.staffLevel = 4".

On clientside, you can use it for storing objects or something. However, they are cleared when the player logs off. You can do stuff like "player.equippedItem = this" for equipping standard weapons.

I will have to lookup putnpc2 since I have never used it.

Just use it like

PHP Code:

putnpc2(x, y, script);

// You can also do

putnpc2(32, 32, "join block;");

// but that's GS1 and poor scripting
// instead, you can use GS2

putnpc2(32, 32, "join(\"block\");");

// but that's a mess and hard to read
// which is why I prefer to do

temp.npc = putnpc2(32, 32, "");
npc.join("block");

// and it's also easier to set attributes this way, such as

npc.spawned = true; 


Also, if I wanted to do something like a toggle, say:

PHP Code:

if (keypressed){
   if (strequals()){
      if (showimgIsAlreadyShown){
         hideimg;
      } else {
         showimg;
      }
   }
} 


How would I detect if said image is shown already?

Try this:

PHP Code:

function onKeyPressed(code, key, char) {
  if (key == "p") {
    temp.img = findImg(200);
    img.visible = ! img.visible;
  }
}

    img.visible = ! img.visible;
  }
} 


Awesome.

Another thing, I was under the impression that variable type is automatically detected, but it seems like setting a variable to a string of text doesn't work?

Trying to do something like this:

PHP Code:

clientr.weapon_img = weaponname.png;

if (trigger){
   showimg index,clientr.weapon_img,,,;
} 


Also, I tried using:

PHP Code:

function onKeyPressed(code, key, char) {
  if (key == "p") {
    temp.img = findImg(200);
    img.visible = ! img.visible;
  }
} 


Not sure how to implement this, as a function, isn't it redundant to do this?:

PHP Code:

if (keypressed){
  onKeyPressed(,p,);
} 


Hrrm, am I doing this properly?


Doesn't this work?

PHP Code:

showimg 200,imagename.png,,,;
hideimg 200;

if (keypressed) {
  if (strequals(#p(1),p)) {
    temp.img = findImg(200);
    img.visible = ! img.visible;
  }
}

You can use GS2 now! Don't be a slave to GS1 conventions.

PHP Code:

function onTrigger() {
  with (findimg(index)) {
     image = clientr.weapon_img;
     x = thiso.x;
     y = thiso.y;
  }
}

     x = thiso.x;
     y = thiso.y;
  }
} 


The thing I don't understand is that this looks like it is outlining a function... so if I made function onTrigger(), how would I call it? Just with onTrigger();?
