Custom ghost baddy

Content Development Script Showcase

I used to have this on the forums before I accidentally deleted all my posts. Anyway, this is a working custom ghost baddy. It is the same one I have on Waffles.

This is the original version. It shows how save[] variables can be used to control NPC execution properly with multiple players in the level.

// Created by Nalin
if (created || playerenters) {
  // Respawn position of the baddy.
  this.loc_orig={36.5,27};
}

// save[0] = hurt damage
// save[1] = x location of player who hurt me
// save[2] = y location of player who hurt me
// save[9] = if 1, is activated, if 0, is resting in grave
if (created || playerenters) {
  // Direction to move.  Can move in 8 directions.  0 is up.  4 is down.
  this.move_dir=4;

  // Number of tiles to move each second.
  this.move_len=4;

  // Set ourself as resting in a grave.
  if (save[9] != 1) save[9]=0;

  // Set our shape so we can damage the baddy.
  setshape 1,48,48;

  dontblock;
  timeout = 0.5;
}
if ((created || playerenters) && isleader) {
  if (save[9] == 0) Reset();
  timeout = 0.1;
}

// Sometimes we can lose our timeout.  Make sure that we don't!
if (isleader) {
  if (npcs[-1].timeout == 0) timeout = 0.1;
}

// If a player touches us and we are in the grave, activate!
// Else, send out a hitobjects to hurt the player.
if (playertouchsme) {
  if (save[9] == 0) {
    save[9] = 1;
    hearts = 3;
    setcharani rha_ghost,;
    timeout=1;
  } else hitobjects 0.5,x+1.5,y+1.5;
}

// Main timeout loop.
if (timeout) {
  if (save[9] == 1) {

    // Check to see if a player in the level hit our NPC.
    if (save[0] != 0) {
      this.hitpower = save[0];
      save[0] = 0;
      doHit();
    }

    // Check if we are dead.
    if (hearts == 0) {
      DropLoot();
      Reset();
      timeout=0.1;
    } else {
      // Move around.
      hitobjects 0.5,x+1.5,y+1.5;
      this.move_dir=int(random(this.move_dir-1,this.move_dir+2));
      if ( this.move_dir < 0 ) this.move_dir+=8;
      if ( this.move_dir > 7 ) this.move_dir-=8;
      this.move_loc={ 0, 0 };
      if ( this.move_dir in {1,2,3} ) this.move_loc[0] = -this.move_len;
      if ( this.move_dir in {5,6,7} ) this.move_loc[0] = this.move_len;
      if ( this.move_dir in {7,0,1} ) this.move_loc[1] = -this.move_len;
      if ( this.move_dir in {3,4,5} ) this.move_loc[1] = this.move_len;
      if ( x+this.move_loc[0] > 61 || x+this.move_loc[0] < 0 ) { this.move_loc[0] = 0; this.move_dir+=4; }

    }
  } else {
    Reset();
    timeout=1;
  }
}

// If a player hit me, save his position and sword power.
// If the leader hit me, we can instantly do the hit code.
// Else, the hit code will be run next timeout loop.
if (washit) {

    // Interrupt our current move and apply a hurt move.

  if ( this.loot in |13,14| ) lay darts;

}

Here is the current version. It requires the latest SVN build of the gserver to run. This version runs smooth for everybody in the level.

I’ve attached the required files. Enjoy.

One angry-ass Casper.

Ive seen the ghost image on Maloria, who made it?

Dunno, but they were the images used for ghost mode when the whole P2P rolled around.

Yeah. I just hijacked the ghost mode graphics that come with Graal.
