HApex 3.0 Lua · Scripting Documentation

Extend the menu · ESP · network · events · drawing with Lua. Every API description maps to a real callable function or field, and the examples are copy-paste ready.

Start with the Guide to get a first script running, then jump into a module below; full field tables are split per-module in the sidebar API section.

Modules

Module	What it does
Menu & Controls gui	Tab / Window / Groupbox containers; checkbox · slider · combobox · multi_dropdown · color_edit · input_text · button · keybind_control · live_table · tips
ESP Elements esp	One-line esp.add for custom text / progress bars / mixed / freedraw; 4 scenarios each with independent colors, slot-based layout
Events event	Render frame · menu toggled · player lifecycle (knocked/revived/died/respawned) · custom events; subscriptions auto-cleaned on script unload
Network net	HTTP GET / POST fully async; WebSocket with 4 callbacks (open · message · error · close)
Live Data game	Local player · enemies · loot · projectiles · aim · ring · map — read-only snapshots
Drawing draw	Lines · rects · circles (incl. clockwise arcs) · triangles · quads · polylines · outlined text · images (incl. rotated) · gradients · color ops (HSV/lerp/mod_a/darken/lighten) · clip stack
Math & Animation math	Vec2 / Vec3 with full operators · projection · 6 easing curves
File & Assets file	Sandboxed file I/O · directory enumeration · PNG / SVG / procedural images
JSON Tools json	encode / decode both ways; pairs naturally with HTTP / file persistence
DMA Memory mem	get_module_base · find_pattern · single reads / scatter batch (u8..u64 / float / vec / bytes / string); read-only, no write
