A projectile changes direction after contacting arena boundaries, making walls part of its future trajectory and extending the threat beyond the initial shot.

Use a stable reflection rule and a visible impact cue so the next segment can be predicted from the incoming angle and surface.

Implementation checklist

Tune the signal, commitment, geometry, response, and recovery of a ricochet projectile as one rule.

Core checks

Three questions for the mechanic

  • Can the player read the complete rule?

    Use a stable reflection rule and a visible impact cue so the next segment can be predicted from the incoming angle and surface.

  • Is the intended response reachable?

    Players should anticipate the bounce, move to a region the reflected line will miss, or manipulate the impact point when the system permits it.

  • Does recovery create a useful outcome?

    The projectile expires after its advertised bounce count or lifetime with a visible fade, so reflected paths cannot remain as unbounded background danger.

Design mistakes

  • Random reflection angles remove the spatial reasoning that distinguishes a ricochet from an ordinary erratic projectile

    Random reflection angles remove the spatial reasoning that distinguishes a ricochet from an ordinary erratic projectile.

  • The cue and active geometry disagree

    If the visible ricochet projectile cue promises a different area or timing, the player cannot carry the learned rule into the next cycle.

Tuning

Tune the attack

  • Tune the complete rule

    Limit lifetime or bounce count, then test speed, collision radius, wall angles, and camera framing across every supported arena shape.

  • Escalate one variable at a time

    Increase bounce count or add destructible reflectors while keeping the reflection law and projectile lifetime visible.

  • Prove the recovery

    The projectile expires after its advertised bounce count or lifetime with a visible fade, so reflected paths cannot remain as unbounded background danger.

Arena

  • What the mechanic communicates

    A projectile changes direction after contacting arena boundaries, making walls part of its future trajectory and extending the threat beyond the initial shot. The encounter uses that rule as a short promise: a visible signal, a committed action, and a result the player can verify.

Player upgrades

  • Adapt it to the player verbs

    Players should anticipate the bounce, move to a region the reflected line will miss, or manipulate the impact point when the system permits it. Limit lifetime or bounce count, then test speed, collision radius, wall angles, and camera framing across every supported arena shape.

Do not confuse this with

  • Keep the mechanic distinct

    Random reflection angles remove the spatial reasoning that distinguishes a ricochet from an ordinary erratic projectile. Do not hide that distinction behind extra effects or tracking that the announced rule does not contain.
