None Marker

A no-op race marker implementation. All methods exist but do nothing, making checkpoints completely invisible. Used when no visual marker is desired.

Class API (OOP via metatable)

How It Works

1. The file returns a factory function that creates a new instance via setmetatable(o, C)
2. Every method is intentionally empty - this marker produces no visual output
3. It satisfies the race marker interface so the marker system can use it without special-casing
4. Contains a commented-out debugDrawer:drawLine in update() for development use

Factory Pattern

-- noneMarker uses the standard marker factory pattern:
return function(...)
  local o = {}
  setmetatable(o, C)
  C.__index = C
  o:init(...)
  return o
end

Usage Example

-- In scenario JSON, set marker to "none" to hide all checkpoints:
-- { "track": { "customMarker": "noneMarker" } }

-- Or create programmatically:
local createMarker = require("scenario/raceMarkers/noneMarker")
local marker = createMarker(1)
marker:createMarkers()  -- does nothing
marker:setToCheckpoint(wp)  -- does nothing
marker:setMode('default')  -- does nothing

Key Notes

• Implements the full marker interface with all methods as stubs
• Useful for scenarios that use waypoints for logic but don't want visible markers
• No TSStatic objects are created, so zero rendering overhead
