A Stealth Game

This javascript game is a project of the "Software de Entretenimiento y Videojuegos" subject of the "Escuela de Ingeniería Informática de Oviedo".

The task of the project is to create a javascript game without external libraries and using a simple but useful game engine provided by the teachers.

The game can be found here: https://jesqm.github.io/stealthGame/, it does take some time to load (does weight quite a lot for a web page).

Controls

• Movement: Arrow keys

• Select weapon: numbers; 1, 2

  • Weapon must be picked up first.

• Attack: space bar

  • A weapon must be equipped.

• Mute: M or N

  • M mutes all the sound.
  • N mutes just the music.

Features

All available features can be explored in the first level easily, as weapons, key, door and hostages are close to the player.

Game Mechanics

Game items

• Items may be picked up in order to use them.
• Sword and Shield can be selected and used as a weapon.
• Swords damage enemies you stand near when pressing space, after a brief delay.
• Shields may only be used to deflect incoming arrows.

• The key must be picked up in order to open the door that leads to the next level.

Enemies

• All enemies have a field of view, showed by the purple rectangle.
• Enemies will follow the player if he stands in front of the rectangle, with no wall blocking. If the player is seen, the background music will change.
• Two kind of enemies (Sword enemies, Bow enemies).
• Sword enemies will have a sword and will follow and melee the player or hostages.
• Bow enemies will slowly walk towards the player or hostages if seen, shooting arrows at them.
• If an enemy receives damage, they will stagger, so their speed will decrease briefly and increase back to a fraction of their total speed (in other words: a nearly dead enemy will walk much slower than a full health one).

Hostages

• Hostages may be rescued to earn points (green circles).
• Hostages must be delivered alive to the door in order to earn points.
• Hostages will follow the player chain-like (following the last hostage).
• Enemies that see free hostages will target them, still, prioritizing the player.

Bushes

• Bushes will hide the player from enemies (the player, not the hostages).
• You cannot hide while being followed by an enemy, you must lose it first.
• You can notice you are hidden due to the reduced view of the map you have and the slight music change.
• While hidden, you can perform a critical hit to an enemy; attacking an enemy will deal a killing blow.
