NoEndermanInBrightArea

This plugin stops enderman from spawning in bright area by just cancel the spawn event if the block light level is not zero.

@EventHandler
public void onCreatureSpawn(CreatureSpawnEvent event) {
  if (event.getEntityType() != EntityType.ENDERMAN) return;
  if (event.getLocation().getWorld().getBlockAt(event.getLocation()).getLightFromBlocks() == 0) return;
  
  event.setCancelled(true);
}
