Group enemies for 3 and 4 players

tightninja · May 15, 2026

Is there anyway to adjust the group function for 3 and 4 players

for example we have:

group 3 3
at
120

Is there a way to have

3pgroup 3 5
at
120

4pgroup 3 6
at
120

No. You can control individual spawns on player count basis, but not group sizes. That would require script.

I am interested on this as well, how could be implemented? at times 2pspawn and 3pspawn are not enough, and a different group quantity is needed for that amount of players.

Like DC said, scripts are the best way in this case.

I suggest using spawn scripts or inline like the method below with a dummy entity. This way, by using it in conjunction with other functions like spawn01, you can fully control many aspects of the spawns.

Code:

spawn GroupX
@script
void main()
{
    setentityvar(getlocalvar("self"), "name1", "GalsiaB_");
    setentityvar(getlocalvar("self"), "name2", "DonovanB_");
    setentityvar(getlocalvar("self"), "groupLimit", 5);
    setentityvar(getlocalvar("self"), "spawnLimit", 8);
    setentityvar(getlocalvar("self"), "screenEdge", 0);
    setentityvar(getlocalvar("self"), "distanceEdge", 100);
}
@end_script
map 0
flip 1

I think I've shared this trick for this question before. The trick is to set big group for 4 players and spawn fake enemies to reduce the group size. These fake enemies will remove themselves based on number active players. Of course, they'll remove themselves when a wait is over (all enemies defeated) to allow progressing.

Hey Kratus,

How to does that script work in practice? From what I can tell Galsia and Donovan only spawn if enemies fall below 4 and with a max of 8?

in other words:

// If 4 players are present, Galsia and Donovan will spawn and change grouping from 3 3 to 5 8
4pspawn GroupX
at 650

Is that correct?

Yep, this is what I do too.

@tightninja Not exactly. In the code I posted the "5" is the group limit, it means how many enemies can be spawned at the same time.
And the "8" is the spawn limit, it means the total enemies that will be spawned before this dummy disappears.

Basically it works by spawning an invisible Dummy enemy that will be always active until the spawnLimit is reached. Then, this dummy has a thinkscript running all the time, checking some conditions and acting accordingly.

Dummy

Think script

This is just an example, you can define any other rules if you want.
However, before diving in this script I suggest testing the Ilu / Bloodbane's method first, looks easier for your case.

@Bloodbane

How do the fake/dummy enemies know when remove themselves? Can you provide a script example?

I don't know exactly but I suppose it may be something like this

Code:

group 6 6
at 120

spawn Galsia
coords 550 230 0
at 120

spawn Galsia
coords 550 230 0
at 120

spawn Galsia

at 120

spawn Galsia
@script
void main()
{
 void self = getlocalvar("self");
 int players = openborvariant("count_players");
 if(players < 3)
 {
     killentity(self);
 }
}
@end_script

spawn Galsia
@script
void main()
{
 void self = getlocalvar("self");
 int players = openborvariant("count_players");
 if(players < 4)
 {
     killentity(self);
 }
}
@end_script

spawn Galsia
@script

{
 void self = getlocalvar("self");
 int players = openborvariant("count_players");

 }

Originally I was thinking of fake enemies with their own scripts in which they remove themselves based on number of active players. They also wait for order to remove themselves.
Turns out there's a simpler solution than that. Here's an example of level with this method:

Code:

group    4 4
at    100

spawn   FakeEn
@script
void main()
{
    void self = getlocalvar("self");
    int Plays = openborvariant("count_players");

    if(Plays >= 4){
      killentity(self);
    }
}
@end_script
alias    Holder
coords  240 200
at      0

spawn   FakeEn
@script
void main()
{
    void self = getlocalvar("self");
    int Plays = openborvariant("count_players");

    if(Plays >= 3){
      killentity(self);
    }
}
@end_script
alias    Holder
coords  240 200
at      0

spawn   FakeEn
@script
void main()
{
    void self = getlocalvar("self");
    int Plays = openborvariant("count_players");

    if(Plays >= 2){
      killentity(self);
    }
}
@end_script
alias    Holder
coords  240 200
at      0

spawn   Enemy
coords  480 216
at      0

spawn   Enemy
coords  400 206
at      0

spawn   Enemy
coords  480 216
at      0

spawn   Enemy
coords  400 206
at      0

spawn   Enemy
coords  480 216
at      0

spawn   Enemy
coords  400 206
at      0

spawn   Killer
alias    Holder
coords  400 206
at      0

group    1 1
at    0

group    100 100
at    0

When grouping 4 4 is active, it spawns 3 FakeEns. FakeEn is this invisible enemy:

Code:

name        FakeEn
health         1000
type        enemy
nomove      1 1
stealth        350
antigravity    100
subject_to_wall    0
offscreenkill    3000
nodrop        2


anim    idle
    loop    1
    delay    30
    offset    1 1
    frame    data/chars/misc/empty.gif
    frame    data/chars/misc/empty.gif

FakeEns will reduce group size based on number of active players. If there were 2 players, one FakeEn will remove itself. If only one player, all FakeEn will stay and if 4 players, all FakeEns will remove themselves. All FakeEns have Holder as alias BTW.
Then after all Enemys are defeated, Killer is spawned to remove all FakeEns.
Actually Killer removes all entities with same alias as the former. Here's Killer entity:

Code:

name        Killer
type        none


anim idle
@script
    void self = getlocalvar("self");            //Caller.

    if(frame==1){
      char Name = getentityproperty(self,"name");
      void vEntity;                                       //Target entity placeholder.
      int  iEntity;                                       //Entity enumeration holder.
      char iName;                                         //Entity Name.
      int  iMax      = openborvariant("count_entities");  //Entity count.

      //Enumerate and loop through entity collection.
      for(iEntity=0; iEntity<iMax; iEntity++){
        vEntity = getentity(iEntity);                 //Get target entity from current loop.
        iName   = getentityproperty(vEntity, "name"); //Get target name.

        //Same alias but different entity?
        if(iName == Name && vEntity != self){
          killentity(vEntity);
        }
      }
    }
    if(frame==2){
      killentity(self);
    }
@end_script
    delay    10
    offset    1 1
    frame    data/chars/misc/empty.gif
    frame    data/chars/misc/empty.gif
    frame    data/chars/misc/empty.gif

After Killer moves all FakeEns, all enemies would be gone allowing grouping to change to next entry or allowing wait to be cleared if one has been declared before.

Call me a donkey, but I still can't understand haha, can someone please put a practical example of a random group explaining it? Let's say:

Making a group of 6 6
Turned into a 5 5 enemy group if 2 players
or turn it into a 4 4 group for just 1 player

Dunno if this is possible

tightninja · Wednesday at 11:35 AM

Hey Mr. Q. I am starting to understand.

Looking at Bloodbane's scripts, you spawn invisible enemies that kill themselves to let real enemies take over if the player count is 3 or 4.

// 12 enemies in this section, max of 6 enemies on screen at a time.
// If player count is 2 or less, 2 fake enemies remain Max 4 enemies on screen
// If player count is 3 players 1 fake enemy remains Max 5 enemies on screen
// If player count is 4 players no fake enemies Max 6 enemies on screen

group 4 6

spawn roper
spawn Williams
spawn linda
spawn baker

spawn fake
spawn fake

spawn roper
spawn Wiliams
spawn linda
spawn baker

spawn fake
spawn fake

spawn roper
spawn wiliams
spawn linda
spawn baker

spawn fake1
spawn fake2

The scripting for the fake enemies is complicated. 3pgroup and 4pgroup would be better but it does not currently exist, so this is the work around. In the example above 4 player mode would have the first 4 real enemies and an extra williams and roper

Hope that helps

Group enemies for 3 and 4 players
