Synopsis

A foolish explorer sneaks into the abandoned castle at night and opens a mysterious-looking coffin, unleashing the dormant vampire within. The vampire seeks its way outside in search of fresh blood to consume. Aid the vampire in leaving the castle by solving the various puzzles along the way and harnessing her supernatural powers!

How To Play

The player will play as the main character Danny, who is a vampire trying to leave her castle in search of fresh blood. Danny can jump and perform a Bat Dash, a horizontal dash she can do to reach a horizontally far place, and she can bite humans to control them to help her leave the castle. She dies if she touches any kind of light, so try your best to avoid contact with it.

Core Game Mechanics Showcase

What I did

1. Character controls
   • Custom Joystick
     • Made movement immediate and responsive to the joystick input.
     • Implemented it in a shape of an eyeball
     • Made the touch detection bigger than the actual joystick (half the screen) after receiving playtester feedback.
   • Jump button, Swap button, Ability button functionalities
     • Disabled when not usable
     • Icon changes per character
     • Disabled when game paused
     • Global manager tracks the number of characters that got bit by the vampire and informs the swap button if swapping characters is available. When swap button is pressed, the focus of the camera shifts to the swapped character.
     • Vampire’s bat-dash button has a cooldown-indicator function
2. Character Animation
   • Sliced sprites and set up logic for playing the right animation at the right time
3. General Physics
   • Box
     • When no character is pushing it, it’s always x position and z rotation frozen.
     • It becomes y position frozen when it detects an object underneath the box. If not, its y position is not frozen. Necessary because otherwise, the box would oscillate when player is on top of it.
     • When a character pushes it from the side, the x position gets unfrozen.
   • Box lift and drop
     • The box parents the minion when lifted. Collision between minion and box is disabled. Rigidbody of box is disabled too while doing this.
     • When box is dropped, box is unparented, enable the Rigidbody again and restore the previous settings before it was lifted.
   • Bat dash
     • Uses Rigidbody’s MovePosition() function to quickly dash for a preset distance in a bat form. However, stops when the vampire detects an object at the front or finished moving a preset distance.
   • Scale
     • Each plate object stores the weight and a list of the objects on top of it.
     • The scale object (which has the two plate objects as the child) compares the weight between the two plates and decides the movement of plates.
     • Each plate object identifies one of the objects on top as a minion, iterates through all the child objects of the minion to check if a box is parented to it. Necessary because the rigidbody is disabled when the box is lifted.
