HI! This tutorial is the first in a series dedicated to the creation, management, and use of spawners. We will see how to: create a spawner and how to manage the functions related to collisions, how to use a for loop within it, how to add a delay to the for loop and how to handle it, how to create an NPC and an AI system to use them together with a spawner, and how to spawn special effects generated by a particle system.
