Mirror, Mirror on the Wall

The wall splits into equal zones: one Leader, the rest Followers. The Leader climbs and invents a route; every hold they press lights up in their zone and at the same position in every Follower zone. Pressing their Finish Hold locks the route. The Followers then climb it to their own Finish Hold.

In Replay display the route is revealed to Followers one hold at a time, in the order it was created. Followers may use unlit holds freely — the game never penalises them, so there is no mistake message here by design.

Loading

Load this mode with /mode/load and type tags siiss:

NetAddr("127.0.0.1", 57120).sendMsg('/mode/load', "mirror", 2, 0, "static", "chimes");

Init parameters

Sent in this exact order, immediately after the mode id.

#	Name	Type	Range / default	Description
1	`zoneCount`	`i`	2 – 4 default `2`	Zones, including the Leader’s.
2	`leaderZone`	`i`	0 – 3 default `0`	Which zone leads. Must be less than zoneCount.
3	`display`	`s`	`static`, `replay` default `static`	static — the whole route stays lit once finalised. replay — Followers reveal it one hold at a time, in the order it was created.
4	`soundSet`	`s`	`chimes`, `marimba`, `retro` default `chimes`	Palette for hold and completion cues.

Configured in the engine

Settings from the use case that never cross the wire. The engine applies them; SuperCollider does not need them, so they are not in the protocol.

Setting
Zone colours	Each zone’s unique LED colour.
Finish Hold positions	One per zone, at the top; the engine places and lights them.
Route mirroring	Mapping a Leader hold to the same position in each Follower zone.

Which stage of the game the wall is in.

s phase

s

phase s string "recording" | "following" | "complete": recording — the Leader is building the route. following — the route is locked and Followers are climbing. complete — every Follower has finished.

SuperCollider NetAddr("127.0.0.1", 57120).sendMsg('/mode/mirror/record', 3, 87);

engine (C#) osc.Send(Osc.ModeMirrorRecord, 3, 87);

Plays a cue in the Leader's zone and a quieter echo in every Follower zone.

Replay display only. In static display the whole route lights at once.

A Follower pressed a hold of the route.

Unlit holds are allowed and produce nothing here — only route holds are tracked.

/mode/mirror/finish

engine → sc event since 0.2.0

A Follower reached their Finish Hold.
