👼Script:
Ogre::ManualObject API - create manual mesh
2 new example scripts. New script API: * `enum Ogre::RenderOperation` * `class Ogre::ManualObject` REF | NOCOUNT object type. This is castable to MovableObject. Official tutorial for Ogre::ManualObject: https://ogrecave.github.io/ogre/api/latest/manual-mesh-creation.html * Functions in OGRE SceneManager: `createManualObject()`, `getManualObject()`, `destroyManualObject()` * Extra feature: function `TerrainClass::getHeightAt()` for the MeshedConcrete example to work.

| RIGS OF RODS - bundled scripts | ||
| ============================== | ||
|
|
||
| TIP: you can run any script in game using 'loadscript' command in the console. To display console, press '~' anytime or in simulation go to top menu > Tools > Show console. | ||
|
|
||
| FOR DEVELOPERS: Visit https://developer.rigsofrods.org/ and click "Script-side APIs" link on main page for detailed docs. | ||
|
|
||
| Conventions: | ||
| * Scripts named 'example_*.as' are short introductory scripts that perform one thing, usually showing UI with tips and controls. You can run them using 'loadscript'. | ||
| * Scripts named '*_editor.as' are complete tools. You can run them using 'loadscript'. | ||
| * Scripts named '*_utils.as' are includes - running them directly is not possible, 'loadscript' would result in error "there is no main() function". | ||
|
|
||
| Special scripts: | ||
| * 'default.as' - fallback terrain script, loaded if modder didn't provide custom script. | ||
| * 'base.as' - an include script for terrain, handles some basic object events. | ||
| * 'races.as' - an include script for terrain, implements waypoint-based driving challenges. | ||
| * 'AI.as' - a backend script for the "Vehicle AI" menu in top menubar. Spawns an AI-driven vehicle, as configured in the menu. |
