Just test file for my top secret illuminati project XD.

Entity.js

//#  Minecraft.js  #//
{
  text: "Enderman",
  entityID: "generic.entity.enderman"
  position: [ 0x1af, 0xacf, 0x41f ],
  maxHealth: 0x14,
  id: getRandomEntityID(this.entityType, +new Date()),
  behaviour: 'if this entity face is looked by player then attack, if this entity face is attacked by another entity then attack',
}
 
  
  
//....

if(entity.isStaredBy(Entity.FACE, player) || entity.attackedBy(player))
   entity.attack(player);
