01 — Install & inject​

Getting started — download the package, install VC++ if needed, inject into a supported client, and start the trial.

02 — Bot modules​

Modules overview — cavebot, targeting, healing, refill, and how the pieces fit together.

03 — Lua scripts​

Scripting — load scripts, events, timers, HUD, and the public API modules.

04 — Events & HUD​

Events · HUD — react to game data and draw overlays.

  1. Start from the public API — use documented namespaces (Game, Player, Map, Engine, HUD, …).
  2. Prefer events and timers — react with Game.registerEvent and schedule work with Timer instead of blocking loops.
  3. Validate the client — treat version-specific fields and OTServer behavior as explicit conditions.
function onTick()
  print("HP " .. tostring(Player.getHealthPercent()) .. "%")
end
