Scripting Overview
A scene describes what exists. A script describes what happens.
You attach a script to an entity, and from then on that entity has behaviour: it moves, reacts to input, takes damage, opens a door.
Attaching a script
Every entity can carry a Scripts component. Drag a script file from the Assets panel onto an entity, or select the entity and click Add Script in the Inspector.
One entity can carry several scripts. They run in the order they are listed.
Languages
Renzora routes a script to a language by its file extension.
Rust (.rs) is built in. The editor compiles a Rust script when you save it and calls it once per frame per entity, with full access to the world. See Rust Scripts.
Other languages arrive as backends from the Marketplace. Install one and the engine starts routing that extension to it. Two languages can coexist in one project, and on one entity.
Which languages a project can be written in is decided by which backends are installed, not by how the engine was compiled. Each backend brings its own reference.
When scripts run
Nothing runs while you are arranging the scene. Scripts run in the game you start with Play, or in the editor when you switch on one script's play button in the Inspector.
