Check if Cavalry is running and the Stallion bridge is reachable

Execute arbitrary JavaScript in Cavalry's JavaScript Editor. Use Cavalry's api, cavalry, and ui namespaces. This is the most flexible tool — use it when no specialized tool fits.

Create a new layer in the Cavalry scene. Common layer types: basicShape, textShape, null, colorPlane, ellipse, rectangle, group, subMesh, linearGradient, cameraRig, pathfinder, duplicator, connectShape, noiseDeformer, meshDeformer, stagger, trail, spreadsheet, csvAsset, soundAsset, imageAsset, videoAsset, javaScriptUtility, javaScriptShape.

Set one or more attributes on a Cavalry layer. Attributes use dot-notation paths, e.g. "position.x", "fontSize", "fill.color".

Read the value of an attribute from a Cavalry layer.

Connect an output attribute to an input attribute between layers. Use "id" as the outAttr to connect a layer's main output.

Set a keyframe on a layer attribute at a specific frame.

Apply Magic Easing to a keyframed attribute. Easing types include: EaseIn, EaseOut, EaseInOut, BounceIn, BounceOut, BounceInOut, ElasticIn, ElasticOut, ElasticInOut, BackIn, BackOut, BackInOut, Linear.

Get a list of all layers in the current Cavalry scene with their IDs and types.

Get the currently selected layers in Cavalry.

Select specific layers in Cavalry by their IDs.

Delete layers from the Cavalry scene by their IDs.

Get information about the active composition (resolution, frame range, FPS).

Set the playhead to a specific frame in the timeline.

Render the current frame as a PNG file.

Set a generator on a layer. For example, set a Basic Shape to use an ellipse or rectangle generator. Use api.getGenerators(layerId) to discover available generators.

Duplicate a layer in the scene.

Get the bounding box of a layer (useful for positioning).

Save the current Cavalry scene. Optionally save to a new path.

Open a Cavalry scene file (.cv).

Add a dynamic attribute to a layer (e.g., on a JavaScript Utility). Types: "int", "double", "bool", "string", "color", "int2d", "double2d", "position2d".
