Adding NPC through the player

Hi everyone
I'm trying to add NPC through the player itself.

Yes, I know that the "normal" method is add through the stages files (same thing with enemies, weapons or objects in general), but the main problem about this method is that the NPCs would have to be added at ALL stages, every single file....which is painful. Not to mention that if I wanted to change some NPC, would have to change every file, every line too... yea, just no.

(Of course, if there is a way NPC remain through the game (stages) that would solve the problem, but I don't think there is such option....)

So I came to the conclusion that perhaps the simplest and most practical method would be to generate a NPC through the player itself. In this case, with a key.
Example: If I'm playing with Ryu, I press "F1" on my keyboard and pum... i have Ken as NPC. No mystery.
And if the stage changes... I press the key again. Easy, fast... (and I don't need to edit stages anymore!)

I know how to add NPC/enemies through the stage files, but I have no idea how to do the same on characters files...
I'm reading openbor manual but I still can't understand exacly how I can do that.

Why does the script below work up to a certain point in the level, in the sense that when there are no enemies, the npcs approach me and stand still, whereas when I continue a bit in the level the npcs change from follow to chase?

Couldn't tell more without looking at each NPC's text. The script you've quoted above only shows each NPC's spawn, nothing in the script defines their AI.
NPCs action is most likely defined by their default AI which is chase enemies and beat them.

@Bloodbane
is it possible to make the script below so that when npcs are spawned the player is subtracted 1 life?

I've analyzed the script and can see 2 major flaw which cause the problem.

I won't focus on that for now but instead focus on my suggestion, which is this:
C:

    void vSelf = getlocalvar("self"); //Calling entity.

    float fY = getentityproperty(vSelf, "y"); //Y position of caller.
    float fZ = getentityproperty(vSelf, "z"); //Z position of caller.
    int Dir = getentityproperty(vSelf, "direction");
    int Map = getentityproperty(vSelf, "map");
    int PIndex = getentityproperty(vSelf,"playerindex"); // Get player's index
    int PLives = getplayerproperty(PIndex, "lives");
    void img;

    if(PLives > 1){
      clearspawnentry();
      setspawnentry("name", "Haggar_");
      img = spawn();
      changeentityproperty(img, "parent", vSelf);
      changeentityproperty(img, "position", fX-100, fY, fZ-1);
      changeentityproperty(img, "map", Map);
      changeentityproperty(img, "direction", Dir);

      PLives = PLives - 1;

Thank you very much!!! I had to deactivate the line Plives = Plives - 1 because it subtracted 2 lives instead of one and I modified the script so that with one life subtracted, all 4 allies are spawned. :)

I've analyzed the script and can see 2 major flaw which cause the problem.

I won't focus on that for now but instead focus on my suggestion, which is this:
C: 
anim    spawn
@script
  if(frame==1){
    void vSelf = getlocalvar("self"); //Calling entity.
    float fX = getentityproperty(vSelf, "x"); //X position of caller.
    float fY = getentityproperty(vSelf, "y"); //Y position of caller.
    float fZ = getentityproperty(vSelf, "z"); //Z position of caller.
    int Dir = getentityproperty(vSelf, "direction");
    int Map = getentityproperty(vSelf, "map");
    int PIndex = getentityproperty(vSelf,"playerindex"); // Get player's index
    int PLives = getplayerproperty(PIndex, "lives");
    void img;

    if(PLives > 1){
      clearspawnentry();
      setspawnentry("name", "Haggar_");
      img = spawn();
      changeentityproperty(img, "parent", vSelf);
      changeentityproperty(img, "position", fX-100, fY, fZ-1);
      changeentityproperty(img, "map", Map);
      changeentityproperty(img, "direction", Dir);

      PLives = PLives - 1;
      changeplayerproperty(PIndex, "lives", PLives - 1);
    }

    if(PLives > 1){
      clearspawnentry();
      setspawnentry("name", "Kassar_");
      img = spawn();
      changeentityproperty(img, "parent", vSelf);
      changeentityproperty(img, "position", fX-100, fY, fZ-1);
      changeentityproperty(img, "map", Map);
      changeentityproperty(img, "direction", Dir);

      PLives = PLives - 1;
      changeplayerproperty(PIndex, "lives", PLives - 1);
    }

    if(PLives > 1){
      clearspawnentry();
      setspawnentry("name", "Mess_");
      img = spawn();
      changeentityproperty(img, "parent", vSelf);
      changeentityproperty(img, "position", fX-100, fY, fZ-1);
      changeentityproperty(img, "map", Map);

      changeentityproperty(img, "map", Map);
      changeentityproperty(img, "direction", Dir);

      PLives = PLives - 1;
      changeplayerproperty(PIndex, "lives", PLives - 1);
    }
  }

I have seen that also with this script sometimes npcs, when there are no enemies, in the level they change from follow to chase. They come back to follow when you start next new level.

Hi @Bloodbane I discovered another thing about to spawn allies cpu through player: If the player dies, his allies cpu from "follow" pass to "chase" automatically even if the player is respawned (they lose the "parent"). Could you add some line of script so that they would continue to have the player as parent? :)

Hmmm... there are 2 issues here:
1. Which player should the ally pick as parent?
2. When should the ally repick his parent?

For #1 if it's singleplayer game, it should be easy.

Here's what happens:
I use this script:
C-like: 
anim    freespecial3
@script
if(frame==1)
{
    void vSelf = getlocalvar("self"); //Calling entity.
    float fX = getentityproperty(vSelf, "x"); //X position of caller.
    float fY = getentityproperty(vSelf, "a"); //Y position of caller.
    float fZ = getentityproperty(vSelf, "z"); //Z position of caller.
    int PIndex = getentityproperty(vSelf,"playerindex"); // Get player's index
    int PLives = getplayerproperty(PIndex, "lives");
    void img;

    if(PLives > 1){
      clearspawnentry();
      setspawnentry("name", "Hannah_");
      img = spawn();
      changeentityproperty(img, "position", fX-100, fY, fZ-1);
      changeentityproperty(img, "parent", vSelf);
      changeentityproperty(img, "map", getentityproperty(vSelf, "map"));
      changeentityproperty(img, "direction", getentityproperty(vSelf, "direction"));

      //se devo aggiungere altri partner ripetere le righe sotto
      clearspawnentry();
      setspawnentry("name", "Mess_");
      img = spawn();
      changeentityproperty(img, "position", fX-100, fY, fZ-1);
      changeentityproperty(img, "parent", vSelf);
      changeentityproperty(img, "map", getentityproperty(vSelf, "map"));
      changeentityproperty(img, "direction", getentityproperty(vSelf, "direction"));

      clearspawnentry();
      setspawnentry("name", "Mustapha_");
      img = spawn();
      changeentityproperty(img, "position", fX-100, fY, fZ-1);
      changeentityproperty(img, "parent", vSelf);
      changeentityproperty(img, "map", getentityproperty(vSelf, "map"));
      changeentityproperty(img, "direction", getentityproperty(vSelf, "direction"));


      changeplayerproperty(PIndex, "lives", PLives - 1);
    }

I've been thinking about this issue for some time and there are 2 solutions I have in mind:
1. Player 1 stores each spawned NPC handle in global variable. When player 1 is respawned, all NPC's handles are acquired than apply player 1 as their parent.
2. NPCs redeclare player 1 as parent if they lost their parent.

#1 is more flexible as it can be used by player 2, 3 and 4 too. But it might require emptying global variable if respective NPC died.
#2 is simpler but not flexible cause the script picks certain player.

Which solution do you prefer?

You can do it both ways, but if you only have to do one then I would prefer the second one since I always play alone :).

If you use the partner menu of @Kratus, when the caller is dead, the npc not passes from "follow" to chase". One of his scripts could be useful for you where it says this feature.
C-like: 
void main()
{//Global keyall scripts, detects player index
    int player = getlocalvar("player");
    
    if(player == 0 && openborvariant("count_players") <= 1){
        menuPartners(player);
    }
}

void menuPartners(int player)
{//Adjust CPU partner mode and aggression
    void self        = getplayerproperty(player, "entity");
    int highlight    = getglobalvar("highlight");
    int hasplayed    = getplayerproperty(player, "hasplayed");
    int dir            = getentityproperty(self, "direction");
    int max            = 6;
    int min            = 0;
    int add            = 1;
    float x            = getentityproperty(self, "x");
    float y            = getentityproperty(self, "y");
    float z            = getentityproperty(self, "z");

    //MAIN COMMAND TO OPEN AND CLOSE PARTNER MENU
    if(playerkeys(player, 1, "attack3") && hasplayed){ //SELECT BUTTON IS PRESSED??

Alright, here's the second solution: in NPC's IDLE and WALK you declare this script:
Code: 
anim    idle
@script
    RePar(0);
@end_script
...
            
anim    walk
@script
    RePar(0);
@end_script
...

RePar is a new function which you should copy to your NPC's animation script. If the NPC isn't using animation script yet, you should declare one which stores this function. Here's the function:
C: 
void RePar(int Num)
{// Reset defined player as parent, if the latter exits
    void self = getlocalvar("self");
    void Par = getentityproperty(self,"parent");
    void P = getplayerproperty(Num, "entity");

    if(P && Par==NULL()){
      changeentityproperty(self, "parent", P);
    }
}


BTW about the first solution, I've found simpler way which doesn't need to use global variable at all. Player only need to find NPCs he/she has spawned before then reapply his/her as their parent.

So you want to spawn NPC together with player right?

The easiest way is to use SPAWN animation which spawns the NPC when player is spawned

Example:
Code: 
anim spawn
    offset    177 162
    delay 8
@script
if(frame==1)
{
    void vSelf = getlocalvar("self"); //Calling entity.
    float fX = getentityproperty(vSelf, "x"); //X position of caller.
    float fY = getentityproperty(vSelf, "a"); //Y position of caller.
    float fZ = getentityproperty(vSelf, "z"); //Z position of caller.
    void img;
    clearspawnentry();
    setspawnentry("name", "Anita");
    img = spawn();
    changeentityproperty(img, "position", fX-100, fY, fZ-1);
    changeentityproperty(img, "parent", vSelf);
    changeentityproperty(img, "map", getentityproperty(vSelf, "map"));
    changeentityproperty(img, "direction", getentityproperty(vSelf, "direction"));
}
@end_script
    frame    data/chars/donovan/spawn01.gif
    frame    data/chars/donovan/spawn02.gif
    frame    data/chars/donovan/spawn03.gif
    frame    data/chars/donovan/spawn04.gif
    frame    data/chars/donovan/spawn05.gif
    delay    30
    frame    data/chars/donovan/spawn06.gif
    delay    5
    frame    data/chars/donovan/spawn07.gif
    frame    data/chars/donovan/spawn08.gif
    frame    data/chars/donovan/spawn09.gif
    frame    data/chars/donovan/spawn10.gif
    frame    data/chars/donovan/spawn11.gif
    frame    data/chars/donovan/spawn12.gif
    frame    data/chars/donovan/spawn13.gif
    delay    8
    frame    data/chars/donovan/spawn14.gif
    frame    data/chars/donovan/spawn15.gif

With this, when Donovan (player) is spawned on field, Anita (NPC) will be spawned right after him
This example uses script but there are non-script way to spawn NPC in SPAWN animation :)



If you want to press key to summon NPC, that's doable. There are two ways:
1. No animation change from player i.e just click of a key

2. Animation change from player or special summon animation

NOTE: I haven't found a simpler example for #2
Click to expand...

@Bloodbane

I was just looking for the code to do what you described for #1

I want to press ability button anytime (while the player is mid attack animation, idle, or walking...NOT in pain though) and an NPC will be summoned without change to the player's animation.

Basically the X-men example you showed I think. Do you have the code for that?

You mean this video:

I have the code for this but aside of its complexity, I'd have to simplify it to remove stuffs from esn's project. IIRC he hasn't released any demo for that yet.

Alright, I've coded a really simple keyscript to summon NPC, here it is:
C: 
void main()
{
    int iPlIndex = getlocalvar("player"); //                 Get calling player
    void vSelf = getplayerproperty(iPlIndex , "entity"); //  Get calling entity
    void vAniID = getentityproperty(vSelf,"animationID"); // Get current animation ID
    void vAniPos = getentityproperty(vSelf, "animpos"); //   Get current animation frame
    void Pain = getentityproperty(vSelf, "aiflag", "inpain");
    void Drop = getentityproperty(vSelf, "aiflag", "drop");
    void Dead = getentityproperty(vSelf, "aiflag", "dead");

    void iAttack2 = playerkeys(iPlIndex, 1, "attack2"); //New key status of "Attack2"
    void Summon;

// Summons an NPC from offscreen behind
    if(iAttack2){ //Attack2 pressed?
      if(Pain!=1 && Drop!=1 && Dead!=1 && vAniID != openborconstant("ANI_RESPAWN") && vAniID != openborconstant("ANI_SELECT")){ // Not in invalid states?
        Summon = spawn02("NPC", -100, 0, 0);

        changeentityproperty(Summon, "parent", vSelf);
      }
    }
}

void spawn02(void vName, float fX, float fY, float fZ)
{
    //Spawns entity based on left screen edge
    //
    //vName: Model name of entity to be spawned in.
    //fX: X distance relative to left edge
    //fY: Y height from ground
      //fZ: Z location adjustment

    void self = getlocalvar("self"); //Get calling entity.
    void vSpawn; //Spawn object.
    int Direction = getentityproperty(self, "direction");
        int XPos = openborvariant("xpos"); //Get screen edge's position
        int Screen = openborvariant("hResolution"); // Get screen width

    clearspawnentry(); //Clear current spawn entry.
      setspawnentry("name", vName); //Acquire spawn entity by name.

   if (Direction == 0){ //Is entity facing left?                
      fX = Screen-fX; //Reverse X direction to match facing and screen length
   }

      fZ = fZ + getentityproperty(self, "z"); //Get Z location and add adjustment.

    vSpawn = spawn(); //Spawn in entity.

    changeentityproperty(vSpawn, "position", fX + XPos, fZ, fY); //Set spawn location.
    return vSpawn; //Return spawn.
}

You can save this as any name you want but you'd have to be consistent when declaring it in character's header.
This script will summon NPC from behind player if Attack2 key is pressed provided: player isn't in pain, falling, rising nor death. Player will be the parent of summoned NPC.
I'm aware that this script is lacking many things such as summon limit, MP cost (if needed), more animation limit (if needed) and more limits but this is a start.
