weapon equip/dequip
 
I've been trying to figure this out for ages, and I simply cannot figure it out.

Essentially I've been having a problem with onWeaponFired and the detection of an equipped weapon.

What I want to do is when the player presses D, it 'equips' the weapon (sets ganis) and when they dequip it (pressing S) it'll reset the ganis. However, when I want to use onWeaponFired it'll immediately fire the weapon even though the weapon isn't equipped by pressing D. I've tried many different ways including with booleans, but it doesn't go over very well because pressing D is the same thing as executing onWeaponFired at the same time. Not really sure how I would go about this.

Also, one thing to note is that this isn't a clone of Era or something I just made the weapon for fun and uhh I know Era uses the same equip/dequip system for guns. First you press D, it equips then you press D again and it fires the weapon.

PHP Code:
//#CLIENTSIDE
/*
  0 dequipped
  1 equipped
*/
function onCreated(){
  this.on = false;
  this.dPress = 0;
}

function onKeyPressed(code,key){
  if (key == "d" && player.weapons[selectedweapon] == this.name && this.dPress == 0){ 
     this.on = true;
     player.chat = this.dPress;
     gravAni();
     this.dPress = 1;
    // this.increment += 1; 
  }
  if (key == "s" && player.weapons[selectedweapon] == this.name && this.dPress == 1){ 
     this.on = false;
     gravAni();
     this.dPress = 0;
     player.chat = this.dPress;
  }
} 

function gravAni(){
  if (this.on){
    replaceani("idle", "gravgun_idle");
    replaceani("walk", "gravgun_walk");
    setani("gravgun_idle", NULL);
  }else if(!this.on){
    replaceani("idle", "idle");
    replaceani("walk", "walk");
  }
}

function onWeaponFired(){
 if( this.on ){ // if equipped, fire
      setani("gravgun_fire", NULL);
    player.chat = "Fired";
    //  player.chat = this.dPress;
      //sleep(this.increment - );
      //  player.chat = "Fired for " @ this.increment;
      //  setani("gravgun_idle", NULL);
 }
} 
Is there a way to prevent onWeaponFired from being executed this way?

cbk1994 09-10-2011 09:49 PM
PHP Code:
function onWeaponFired() {
  if (! this.isEquipped()) {
    return this.equip(); // it's not already equipped, so equip it
  }
  
  // it's already equipped
  this.fire();
}

function GraalControl.onKeyCode(temp.code, temp.key) {
  if (temp.key == "s" && this.isEquipped()) {
    // pressed "s" while equipped, unequip it
    this.unequip();
  }
} 
Just do something like this.


Also, note that this is incorrect:

PHP Code:
player.weapons[selectedweapon] == this.name 
weapons is an array of weapon objects, not weapon names. The only reason it works is because the weapon object is coerced into a string, which is then compared to the current weapon's name.

The correct way would be to do
PHP Code:
player.weapons[selectedweapon] == this 
However, the best way would just be to do

PHP Code:
player.weapon == this 
(player.weapon always refers to the currently selected weapon)

Make a system npc to manage the equipping and un-equipping. I.e:

-System/Equipment

PHP Code:
//#CLIENTSIDE
public function equip(wep) {
  if (isEquipped(wep)) {
    unequip();
  } else {
    this.equipped = wep;
  }
}

public function unequip() {
  this.equipped = "";
}

public function isEquipped(wep) {
  return (this.equipped == wep);
} 
then in your weapon you can do:

PHP Code:
//#CLIENTSIDE
function onWeaponFired() {
  // Equip/Unequip Weapon
  ("-System/Equipment").equip(this);
  // Check if Weapons is Equipped
  if (("-System/Equipment").isEquipped(this)) {
    // set appropriate anis
  } else {
    // return anis to normal
  }
}

function onKeyPressed() {
  if (("-System/Equipment").isEquipped(this)) {
    if (keydown(5)) fireWeapon();
  }
}

function fireWeapon() {
  // pew pew pew
  // RED DRAGONS
} 
This is just a basic implementation, you can expand upon it and do more in -System/Equipment to the point where all you're doing is setting different configuration variables in your weapons.

Also use keydown(5) instead of key == "s" that way players can re-assign the attack key via F3 Options.

The only thing I don't understand is why you wrote ! this.isEquipped() instead of !this.Equipped? How can you check empty parameters like that? (cbk) FP4: by 'system' NPC do you mean a class or an actual system NPC? Also why would I want to fire with the S key? wat

Preference.

Don't the parameters reference a function?

fowlplay4 09-10-2011 10:13 PM
An actual weapon NPC.

I misread your post but I feel if you're going to use D/keydown(4) to equip/unequip weapons you should use a different key to actually fire the weapon otherwise why even bother equipping them.

Missed the parenthesis. Thought you were talking about the space after the exclamation mark. I guess he put the parenthesis by accident.

That's the whole reason I made this forum post, lol. How would I equip and then fire?

I already displayed my method of doing so.

I don't want to like spam the thread by asking meaningless questions, but essentially what you mean by System NPC is to create an NPC called -System/Equipment (does the -System even mean anything? wat) (on testbed mind you) and manage the equipping and dequipping of weapons? Huh? Why would you create a SYSTEM Npc for that? Why not a class?

A class is basically just for pasting functions into your script/weapon/level-npc. It doesn't actually exist as anything until it's joined to an DB-NPC Weapon-NPC, Level-NPC, or an object.

By System NPC I just mean a weapon that is added to the player that's primarily used for background tasks and as a database. In this case it's used to keep track of what weapon you currently have equipped and provides a standard way of equipping a weapon.

If you have two weapons: A and B, and you equip A how will B know that you have equipped A if you only tell A that it's equipped?

To deal with that you use a system npc and route your equip requests through it like my example does.

You don't have to use -System/Equipment as the weapon name either, you can use any name just make sure you update the scripts to make calls to it instead of -System/Equipment.

Weapons in Graal are not necessarily (and usually aren't) actual usable weapons. Classes are kind of like includes; they can't be on their own, they have to be joined to a weapon or NPC.

isEquipped() is just a function, you can either define it or use a variable directly.

No, I did it on purpose. I like to use functions for this kind of thing as it gives far more flexibility and makes it easier to make changes in the future.

Ah OK. I thought you meant an actual NPC, but you just meant a weapon used as a System.

edit: nothing works and I pretty much managed to messed up my weapons to the point that I can't even execute a basic player.chat, will probably have to make a completely different thread attempting to fix this (it's probably a server bug not sure)

Anyway thanks for attempting to help me I guess
