ShowScript is a frame-accurate show-control programming language and runtime ecosystem for synchronized audio, lighting, video, effects and external I/O.

It is built for theme park rides and immersive experiences, such as escape rooms, haunted houses, museums, and more, that require deterministic execution, while still enabling fast creative development.

Why Use ShowScript¶

• Deterministic, frame-based execution for time-critical behavior
• Parallel timeline model that stays readable as systems grow
• Strong validation and pre-compilation before runtime
• Practical tooling for debugging, simulation and deployment workflows

Built For¶

Theme Park Engineering Teams¶

ShowScript supports industrial-grade control scenarios where repeatability, observability and controlled change management matter.

Technical Hobbyists and Makers¶

ShowScript makes advanced show control approachable with a script-first workflow, ready-to-use templates, and integrations that help you prototype fast and scale when needed. Whether you are building a haunted house, an escape room, or any immersive experience, ShowScript provides the automation backbone your project can rely on.

Components¶

• ShowScript Language (.shs): Human-readable scripting for sequence logic and parallel timelines
• ShowScript Engine: Runtime for validated, deterministic showscript execution
• ShowScript IDE: Friendly Windows based IDE for editing code, simulation and workflow utilities
• Drivers and Integrations: Art-Net/DMX, audio systems, video playback, API interfaces, HMI's and external I/O modules

Releases¶

v1.0.38 (2026-03-08): Maintenance release. Added trace logging when an audio device gets lost (for example after USB disconnect), added CPU and memory information to the API /state endpoint, improved starting GUI processes in the Process driver, and fixed panels behind reverse proxies.

v1.0.37 (2026-02-25): Final release of ShowScript v1 before the major v2 release. Added Trace Window export to .csv in the IDE. Added a new Web Panels switch push button type with automatic timeout options, graphics/icons support for buttons, and a driver option to show IP addresses on displays of all connected web panels. Improved interpreter exception handling for lost audio interfaces.

v1.0.36 (2026-02-22): Added conditional logic support (IF/ELSE and conditional jumps), added lock-after-press support for web panel buttons with visual countdown indicator, expanded trace() to support object values and string concatenation, added an engine-stop trace with the source/reason of exit, and fixed a WinIDE issue where dragging and dropping a file in the same folder could append (1) to the filename.

v1.0.35 (2026-02-17): Added drag-and-drop in the project explorer, introduced Syslog and Panels drivers, added VCA support with a template, delivered an OpenAPI browser and user/role authentication for the API driver, and improved ASIO sample-rate mismatch handling with automatic resampling.

v1.0.34 (2026-02-04): Added the ControlByWeb X417 simulator and engine driver, improved project-open path memory in the IDE, and fixed robustness issues in ASIORouter initialization and WASAPI driver name handling.

v1.0.33 (2026-01-10): Enhanced WebPanel onClick actions with support for showscript, panel-link, javascript, and hyperlink link types.
