To develop and test our NPC systems, we need a simple Prefab to represent our NPC character. Once this is working, we will be able to add polish to the game by replacing it with a more visually appealing model and by adding animation. To begin with, create a capsule with a scaled hat similar to the player Prefab placeholder.
The npcScript class will encode the base state machine for NPCs. To develop a robust non-player character system requires a model of the behavior we want to present to the player. Once we have a model, we can build an FSM that meets our functional needs. We shall list these requirements in the following part.
In our e-learning game, the non-player characters will need to do the following:
Travel about the world in a smooth, realistic way
When approached by the player, the NPC should stop and face the player to interact
When the player leaves the NPC or finishes the interaction, it should continue moving about the...
