Unity Interactive Environment

WIP!

Unity 2022.3.13f1, URP, Vulkan.

Pet Project: Graphics Programming / Technical Art for Game development.

Gameplay

Two ways of player control:

• Modifying the environment
• Moving the player

TAB to change PLAYER mode or BUILDING mode.

PLAYER MODE: 
+ W/A/S/D to add torque.
+ SPACE to add force up.

BUILDING MODE: 
+ LEFT CLICK to select. 
+ ESC to deselect.
+ W/A/S/D/E/Q to scale. 
+ MOUSE MOVE to move. 

Gameplay (TODO):

• At game start, generate randomized start and goal positions.
• Player is positioned at start position.
• Player modifies the environment in order to move to the goal position.
• Each environment modification operation must be optimized since it results in penalty points.
• Player is time restricted; laser is moving from bottom to top and if it touches the player the game ends.

Interacting with environment:

• Ray-casting for selection
  • TODO: ray-cast layers and 4th wall
• Scaling and translation of selected objects
• RBD behaviour

Interacting with player

• RBD behaviour
• Movement using torque and forces

Shaders:

• Normal-based unlit shader for color
• SSS approx using unlit shader:
