FAQPage Schema
How do I set an opened Unity scene as active during development?

To set an opened Unity scene as active, send a POST request with a valid sceneRef payload. This payload must contain the scene instanceID and asset metadata to locate and activate the target scene quickly.

What is the best way to automate Unity scene switching for testing?

Automating Unity scene switching uses an API call to set a specific opened scene as active. This streamlines development workflows by enabling rapid scene transitions during testing and iteration.

Do I need a specific payload format to activate a Unity scene via API?

Yes, activating a Unity scene requires a sceneRef payload containing instanceID and asset metadata. This data structure is necessary for the API to correctly identify and set the target scene as active.

Can I use scene-list-opened to find scenes before setting one active?

Yes, scene-list-opened integrates directly with scene activation workflows. Use scene discovery tools first to identify candidate scenes, then pass the retrieved sceneRef data to set your chosen scene as active.

Why does my Unity scene activation fail despite multiple scenes being open?

Unity scene activation fails if the sceneRef payload lacks valid instanceID or asset metadata. Ensure the target scene is actually opened in the Unity editor and that all required identification fields are correctly provided.

Does scene-set-active work with Unity projects containing multiple open scenes?

Yes, scene-set-active is designed specifically for Unity projects with multiple open scenes. It directly activates a chosen opened scene, supporting rapid scene switching during development and testing.
