SDK 6.3

Official WOWCube SDK 6.3 documentation. Canonical API reference, generated from the SDK headers.

The current WOWCube SDK. Applications can be written in PAWN, C++, or Rust.

PAWN API

Legacy: supported, but no longer actively developed (last PAWN additions — SDK 6.2; 6.3 only removed deprecated calls). For new projects use the C++ API. One page per module:

• SDK 6.3/PAWN/Core — application lifecycle, state, time, RNG, packets
• SDK 6.3/PAWN/Graphics — drawing, images, text, shaders (GFX)
• SDK 6.3/PAWN/Topology — cube geometry, facelets, twists
• SDK 6.3/PAWN/Sound — sound playback
• SDK 6.3/PAWN/Motion Sensor — accelerometer / gyroscope, taps
• SDK 6.3/PAWN/Leaderboard — scores and achievements
• SDK 6.3/PAWN/Splash Screen — splash screens
• SDK 6.3/PAWN/Physics — 2D physics helpers
• SDK 6.3/PAWN/Network — inter-module messaging
• SDK 6.3/PAWN/Save — persistence
• SDK 6.3/PAWN/Scramble — cube scramble
• SDK 6.3/PAWN/Logging — debug logging

• SDK changelog — what changed in 5.1 / 6.0 / 6.2 / 6.3

C++ API

C/C++ cubeapps run via WebAssembly: the same engine functions as PAWN, plus an object-oriented framework and a retained scene graph. This is the primary development track.

Native engine ABI — SDK 6.3/C++/Native API (all 64 functions with full descriptions):

• Core — time, RNG, packets, BLE, saves, user, version, logging
• Graphics — drawing, images, text, shaders, QR, render targets
• Topology — facelets, faces, twists, orientation
• Sound — playback and caching
• Motion Sensors — accelerometer / gyroscope per display
• Leaderboard — scores and rankings
• Types & data structures — structs, enums, constants

Application framework — SDK 6.3/C++/Application:

• Entry point · callbacks (on_Tick, on_Render, on_Twist, …) · timers, networking, saves, AppManager

GFX Engine (scene graph) — SDK 6.3/C++/GFX Engine (56 documented methods + official-sample code):

• The canonical pattern — how real games are structured
• Scene · SceneObject · Screen
• Sprite · AnimatedSprite · SpriteAtlas · Background · Text · QRCode · OffscreenRenderTarget
• Sound / SoundCollection · NetworkMessage / SaveMessage · Scramble · Splashscreen · Math

Rust API

Experimental / advanced track (crate wowcube_sdk v0.1.0): actively shipped with SDK 6.3, builds to the same WebAssembly ABI as C++.

• Crate layout — modules application and cubios
• Application trait — on_init / on_tick / on_render / on_timer, timers
• Entry points — on_init(cid) / run()
• FFI types — topology, leaderboard, particles, enums
• Examples — three buildable projects in the DevKit
