[Script] Enemy Spawn Limiter

[Viper Snake]

I couldn't find any scripts here for this, so I made my own by modifying the MP limiter script. This will prevent an enemy from performing an animation based on how many are alive.

void spawnlimiter(int Limit)
{// Prevents an enemy from performing an animation if there are too many enemies alive.
 // Viper Snake - 6/16/2015
    void self = getlocalvar("self");
    int spawnMAX = openborvariant("count_enemies"); //How many enemies?
    int y = getentityproperty(self,"a"); //Get entity's altitude
    int b = getentityproperty(self, "base"); //Get entity's base

   if(spawnMAX>=Limit) //Enemy limit reached?
   {
     if(y > b) // Mid air?
     {
       changeentityproperty(self, "animation", openborconstant("ANI_JUMP") );
     } else{
       setidle(self); //Don't play the animation
     }
   }
}

Usage: @cmd spawnlimiter <enemy limit>

Example:

The Melty Zombie from Castlevania: Harmony of Dissonance can spit out acid that creates another Melty Zombie. This script prevents the game from eventually locking up due to a massive amount of Melty Zombies on screen.

Hi Viper.
I think you had posted the wrong code. That code, actually, checks if the entity is on the air and, if so, changes to the JUMP animation. There is no entity check on that.

That is just so the entity animation looks good if airborne when trying to attack instead of just using idle. This script uses "count_enemies" to check how many exist.

Ah, Now it uses count

Ah, Now it uses count

I didn't change the script at all, when I edited my original post I fixed a small typo:
Usage: @cmd <enemy limit>
to
Usage: @cmd spawnlimiter <enemy limit>
It was correct in the example.
