Tail's Adventure

General Informations

Synopsis

Tails, who decided to be alone for a time, notice that Eggman’s robots
are invading the Mystic Ruins. He decides to stop them using his genius
and his constructions. Unfortunately, a robot ended up breaking his
tails, depriving him of his ability to fly

My Work

Program 3C and features, create and implement VFX.

Main Features

Patrol System

Patrol is compatible with Melee and Ranged enemies. A list of empty objects containing path points script is set in the enemy script (in the editor). An index is set to 0 at the start of the game and first path point of the list is set as the current path point. First, the AI is rotated in the direction of the current path point, then each frame the distance between enemies and path point is calculated and as long as it is greater than 0 a forward velocity is added to enemy rigibody. When this value is equal to 0, velocity is removed and a variable « path point time« , contained in the path point, is taken. A timer is started and when « path point time » is reached, the next path point is taken and behaviour is repeated

Constructions

Each constructions must be unlocked by taking collectibles. When input is pressed, the cost of the construction is checked and if it is equal or less than scraps number, a small force is added to the player in up vector direction and current selected platform is instantiated at the player position.
For the bumper, when a player enters in bumper trigger a force is added in the vector up direction for a while.

Classic Attack

When the input is pressed, collider and mesh of the weapon’s are activated. Animation starts and if weapon collides with the enemy collider, it removes health. Damages can be set in the editor.

Scrap Attack

Scrap attack must be unlocked by picking a collectible on the map. When input is pressed, a projectile is launched with a force set in the editor. Each frame a line is drawn from the projectile in the direction of the ground, if the line hits the ground, the explosion trigger is activated and all enemies present take damage.

Wall Jump

Every frame, a line is traced in front of the player to detect wall. When jump input is pressed, if the line hit a wall, a force is added in the opposite direction of the player’s vector forward for a certain time.

Spin Attack

When input is pressed, a force is added for a while in the direction of the player’s forward vector. If the player collides with the enemy collider, it removes health. Time attack and damages can be set in the editor.

Melee Enemy

When the player character enters into enemy’s field of view, patrol behavior is stopped and « SeePlayer » behavior is started : Each frame enemy is rotated in the direction of the player. The distance with player is checked and while it is greater than 0, a forward velocity is added to reach the player. When the player is reached, a timer is started and when it expires an animation is played, if the player character enters in enemy collider, health points are removed. Damages taken, can be set in the editor).

Distance Enemy

The only difference with melee enemy is Distance enemy doesn’t move, a delay can be set in the editor and each time this delay is reached, a projectile is instantiated.

Each frame a forward velocity is added to the projectile, if the projectile enters in player collider, health points are removed (damages taken can be set in the editor).

Stun

Stun is compatible with melee and distance enemies. A trigger is placed over the enemy. Another trigger is placed at the below the player. When player is in the air if player is falling and the two triggers collide, enemy behavior is stopped for a while and once delay is reached « SeePlayer » state is reactivated.

DOCUMENTATION

For this project I made a document to explain my development patterns and how my code works :

Enemies

I took the example of enemies, melee and distance enemies share different properties, they have 2 general states : « Patrol » and « See Player« .

In patrol state enemies can follow a path or stand still, if player enters their field of view, state changes
