DraggerService

Inherits from: Instance → Object

DraggerService is a central hub for dragger-related settings that Studio's dragging tools (and other dragger-like editing UX) read when deciding how to move, snap, and highlight objects. Because the Move, Scale, and Rotate tools all consult the same service, changing a setting here keeps their snapping, collision, joint, and hover behavior in sync. Each property reflects the corresponding Studio editing preference or global editing state.

DraggerService.AlignDraggedObjects

When true, a dragged object is rotated to align with the surface it is dropped on instead of keeping its original orientation. This reflects Studio's "Align Dragged Objects" editing preference and is read by the dragging tools.

DraggerService.AngleSnapEnabled

When true, rotating an object with a dragger snaps the rotation to multiples of DraggerService.AngleSnapIncrement. When false, rotation is continuous and the increment has no effect.

FieldValue
typeboolean

DraggerService.AngleSnapIncrement

The rotation snapping step, in degrees, applied while DraggerService.AngleSnapEnabled is true; it has no effect when angle snapping is disabled. The value is clamped to a small positive minimum, so it can never be set to 0 or a negative number.

DraggerService.CollisionsEnabled

When true, dragging performs collision checking so that a moved object stops against other parts instead of passing through them. When false, objects can be dragged freely through existing geometry.

DraggerService.UseBoundingBoxes

When true, the dragging tools use the axis-aligned bounding box of an object for snapping instead of its precise geometric shape. This can simplify placement when objects have complex geometry.
