You have placed your first enemy and can now interact with them. Having characters to breathe some life into our story and game gives us tons of gameplay possibilities by simply placing them in progressive and interesting ways. A common mistake when dealing with AI placement is that the characters are placed without being given a task or without being hidden slightly from view. Consider the placement of AI carefully. As this example showed you the procedure of getting an AI entity into the world, it is worth noting that the use of advanced spawning and scripting actions can be achieved using the flow graph, which is explained in the next chapter.

Try adjusting some of the properties of your AI to make it more or less challenging. Change the attackrange parameter to a lower value so that the AI doesn't react until you are very close, or set it very far so that they react to you sooner.

Use the Faction parameter to have the AI fight each other or aid the player by setting them to oppose Faction objects.

Although not essential, it is very good practice, when creating games with a variety of enemies, to create different templates for the player to fight in. We call these templates archetypes. Archetypes store all the properties of their associated entity. For example, you can have archetypes of lights with certain settings, breakable objects with specific parameters, and finally AI entities with specific parameters. In the case of an AI archetype, some of the important parameters could be attackrange, Field of Vision, Health and some other properties.

The most important benefit of using archetype entities is when you consider trying to change every placed AI entities' properties across all levels. Without the archetype entities, you would have to physically go in and change all the instances of each character for it to reflect your changes. Using archetypes allows you to modify this once and affect every single instance across multiple levels at the same time.
