Summary: Radioactive is a thrilling puzzle adventure game set in an abandoned lighthouse containing secret nuclear experiments. The game is played from a first-person perspective, where the player must navigate to the top of the lighthouse using only a flashlight. Due to the radioactive environment, the flashlight quickly becomes corrupted and can be used to burn away objects it lights up. The player can use this ability to navigate safely through many twists, turns, and puzzles and discover new secrets along the way.

Main Gameplay Features:

• First-person perspective
• Radioactive light is harmful to the player’s health (measured by a “Radiation Exposure” bar)
• Player has the ability to wield radioactive light in their flashlight
• Player can gain a “dark beam” ability that blocks harmful light
• A “mirror beam” reflects radioactive light away from the player
• Switches and destroyable objects react to the presence of radioactive light

Implementation Details:

• Light from flashlight is implemented as a spotlight that is a child of the flashlight mesh so that they move together
• Rays are cast from spotlight cone and trigger burn/hit events when intersecting objects
• “Dark beam” is an opaque mesh that blocks light and has no collider
• “Mirror beam” is a triangle mesh with a specular material. When light hits this mirror, a spotlight is generated with the origin at the hit point and direction towards the incoming light’s forward vector
