Frequently asked questions

How do I open the script editor in-game?
Open your inventory and look for the Vortex Scripting Core interface or keybind (check your controls menu). The in-game script editor will appear with code completion and hints enabled by default.
What's the difference between client-side and server-side scripts?
Server-side scripts control game logic, NPC behavior, and quest progression that all players see; client-side scripts handle visual effects, UI, and player-specific interactions. Most quest and NPC systems should run on the server to stay synchronized.
Can I use custom 3D models for NPCs?
Yes, the mod supports glTF, GLB, OBJ, and Bedrock geo.json formats. Import your model through the asset manager or script editor, then assign it to your NPC in the dialogue/animation system.
How do I make an NPC play different animations based on what they're doing?
Use the animation editor to set up state transitions with expression language triggers—for example, trigger 'walk' when the NPC moves, or 'talk' when dialogue plays. The mod syncs these states between client and server automatically.
