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.

How would I do that serverside? I want the baddie to be seen the same by all players... would putnpc work with a class?

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;
  }
}

  }
} 


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;
  }
}

Ugh, I don't know how else to do this.

I want the weapon icon to be displayed dependant on the type of weapon equipped, so..

PHP Code:


if (clientr.weapon = 0001;){
   clientr.weapon_img = weaponicon.png;
}

showimg index, clientr.weapon_img,,,; 


I would assume this would basically do the same as:

PHP Code:

showimg index, weaponicon.png,,,; 


but it's not doing that at all, I'm confused...

Use:

clientr.weapon_img = "weaponname.png"; 


for strings

onKeyPressed is called on default. Basically all of the event if's were converted to "function onEvent", such as "onPlayerTouchsMe", "onCreated", and "onPlayerEnters". There's no need for the if (keypressed) statement.

Hrrm, am I doing this properly?

    img.visible = ! img.visible;
  }
} 


hideimg might be actually destroying the image (actually, I'm pretty sure it does). Just hide it with findImg().visible. And, I don't think showimg has that many paramaters.

Plus.... you're combining GS1 and GS2 in a horrible way

Something like this I guess...

PHP Code:

//#CLIENTSIDE
function onCreated() {
  this.wep_type.sword = "sword.png";
}
function displayImage() {
  showimg(200, getImageForType(clientr.weaponType), 0, 0);
}
function getImageForType(wep) {
  return this.wep_type.(@ wep);
} 


and just set clientr.weaponType or another variable when you change the player's weapon. Also, there's really no reason to use clientr. for a weapon image.

And, I'm pretty sure you're adding an extra parameter to showimg almost everywhere. Press F2 and click on "Scripts", it may be giving an error.

Ahh thanks. And yea, I am not adding an extra parameter in the actual scripts, just mashing the comma here to represent that parameters DO follow.

I did this:

PHP Code:

clientr.weapon_img = "raelyn_sword.png";

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


Still not producing an image.

Edit: Bah, I got it to work with #s.

Ok, sorry to ask this again, but I am still having problems with this.. I am trying to use the GS2 solution and it's not working (I'm probably doing it wrong.)

Here is what I got..

PHP Code:

function onKeyPressed(code, key, char) {
  if (key == "i") {
    temp.img = findImg(209);
    img.visible = ! img.visible;
  }
} 


I have a function doing showimg 209, and trying to use the code snippet you suggested on key i, the image remains shown, and is not hid, as expected.

Is there a way in GS1 to do this?

PHP Code:

if (keypressed) {
   if (strequals(#p(1),I)){
      if (img 209 is visible){
         hideimg 209;
      } else {
         showimg 209,file,x,y;
      }
   }
}
