Project Goals

This project helped expand my Unity programming skills and my teammate’s 3D character creation skills. The Quarrior, a small-scale boss battle game, allowed us to work individually in our fields while striving towards a common goal: create a complex enemy AI and a player with multiple attack mechanics.

“Providing the player with multiple strategies for attacking the boss adds variety to the gameplay and allows for different types of play styles.”

Player Mechanics

To give the player multiple attack and defence strategies, we created a standing and rolling dodge ability, a melee pickaxe weapon and a timed dynamite trap weapon. The player can utilize these tools to plan how they want to attack the boss.

Enemy Mechanics

To make an engaging enemy AI, the boss was given a variety of tools to use against the player including close range stomping and swatting attacks, a long range rock spitting attack, and the ability to pursue the player when they are too far away.

“We designed the boss to have both close and long range attacks to counter different play styles.”

Player Weapon Swap

To create the weapon swap mechanic, I used scriptable objects to store information for each weapon. These scriptable objects contain data such as the weapon name, ID number, model, and more, including an associated action to be used with that weapon. Each of the actions is another scriptable object containing the action ID number that must match the weapon ID, and the animation associated with the action. This way, each weapon has its own unique action which determines what the player does when handling that weapon (swing the pickaxe, place the dynamite).

Enemy Attacks

The enemy uses a state machine to determine how the AI will act based on different conditions. Each state is a scriptable object that contains data on how the enemy will act in that state (idle, pursue, combat stance). Each enemy attack is also a scriptable object which holds data like the animation, the action recovery timer, and the maximum engagement distance of the attack.
The combat stance state checks if the current conditions to use an attack are met, and adds it to a list of eligible attacks. Then, the attack state is called, and an attack from that list is selected and used.
 

Key Learnings

Enemy AI, Scriptable Objects

This project provided an opportunity to learn about scriptable objects, specifically how they can be used to contain reusable pieces of code such as that relating to the player weapons and the enemy attacks. I also have a better understanding of creating complex enemies and the flow of state machines.
