What It Opens
Switches the bottom toolbar to actions that can safely apply to the current selection.
Selected object toolbar
Multiple Selected Objects
When several objects are selected, the toolbar focuses on group operations, copying properties, moving, deleting, and other actions that apply to the current selection.
When it appears
Where this control fits
Appears when more than one object is selected at the same time.
Why It Matters
When several objects are selected, the toolbar focuses on group operations, copying properties, moving, deleting, and other actions that apply to the current selection.
What each control does
Control reference
This page covers two related workflows: editing several selected objects together, and using the real Group Object system where child objects become one controlled container.
Multiple Selection Bounds
When several objects are selected, the editor uses the combined bounds of the selection. Movement, duplicate, rotate, scale, and delete operations use that selection as one working set.
Group-Safe Settings
Only settings that can apply safely to the selected objects are shown. Mixed object types can hide controls that only make sense for one exact object.
Shared Object Settings
Opens physical settings that can be applied to the current selection when the selected objects support those settings.
Object Game Settings
Opens game-system settings that can be applied to the selected objects. This is useful when several level parts need the same trigger, damage, collect, or behavior setup.
Duplicate Directions
Duplicates the selected set left, up, right, or down while keeping properties. This is the fastest way to build repeated machine patterns.
Move Selection
Moves all selected objects together. Use it for alignment after selecting a whole machine section or repeated puzzle assembly.
Scale Selection
Scales selected objects together when allowed. Final collision and joint behavior still needs testing because scaling can change physics results.
Rotate Selection
Rotates the selected set together. Rotation is useful for copying a built mechanism and reusing it at a new angle.
Drag Locks
Locks horizontal or vertical dragging so the selection can move only along one axis. This prevents accidental drift while aligning parts.
Group Object Rule
A real group can contain multiple children, but at most one non-scene physics object. Other children should be scene objects. Nested groups are not allowed.
Group Container
The group behaves as a container. Moving, rotating, scaling, or filtering the group propagates to its children through the display hierarchy.
Current Child
Selects which child inside the group is being inspected or edited through group controls. It is especially useful with focus mode and movie-frame setup.
Child Offset X/Y
Moves one child relative to the group center. Offsets are stored in meters so the group can be saved, rebuilt, and transformed as one unit.
Group Focus Mode
Shows only the current child while editing. Use it when a group has many overlapping parts and the current child would otherwise be hard to see.
Show Previous Frame
When focus mode is enabled, the previous child can remain visible with reduced alpha. This helps tune movie-like frame-to-frame motion.
Previous Frame Alpha
Controls how visible the previous frame/child is during focus mode. Lower values give a ghost reference; higher values show stronger overlap.
Play Group As MovieClip
Makes the group behave like a frame-based animation where children can act as frames. This can create animated machinery, signs, indicators, and decorative motion.
Include In Movie
Controls whether the current child participates in the group movie animation. Excluded children can remain as static parts of the group.
Movie Frame Duration
Sets how long the current child/frame is shown during group movie playback.
Enable Transition
Enables tweened transitions between group movie frames. This makes the animation blend instead of snapping instantly.
Transition Tween Type
Chooses the easing/tween curve used by the transition. Linear gives constant motion; other tween types can feel softer or more mechanical.
Transition Type
Chooses what changes during transition: Alpha, Scale, Blur, or Pixelate. Each creates a different style of frame change.
Transition Duration
Controls how long the transition lasts. Short durations feel snappy; long durations feel like smooth morphing or slow machine activation.
Apply For All Frames
Applies compatible movie settings across all children/frames instead of only the current child.
Align Group Children
Automatically arranges the group children into a chosen pattern. This is much faster than manually placing every child.
Align Type
Available patterns include Horizontal Center, Vertical Center, Center, Circle, Ellipse, Box, Triangle, Crescent, 5 Point Star, 4 Point Star, Half Circle, Half Circle Full, Heart, Diamond, Plus, and Plus Thickness.
Include Main Child
Includes the main physics child in the alignment operation when a group has a physics child. This is only available when the group structure supports it.
X Size
Controls the horizontal size of alignment patterns that use a size value, such as ellipse, box, star, heart, diamond, and plus layouts.
Y Size
Controls the vertical size of alignment patterns that need a second dimension. Circle uses one size; ellipse and many shape layouts use both X and Y.
Child Stacking
Group children are sorted by scene layer, layer group, and display container index so front/back order remains predictable inside the group.
Physics Child
If a group contains a non-scene physics child, that child anchors the group's physics behavior. Group rotation combines the group rotation with the physics child's local rotation.
Child Selection
Children inside a group are not individually touchable/selectable while grouped. Use current child and focus mode, or remove the child from the group for standalone editing.
Trigger Zone Movie Controls
Trigger zones can change group movie playback, loop-frame range, or force a specific movie frame. This lets a puzzle system drive grouped animation.
Chip Movie Outputs
Chip output targets can drive Movie Clip Frame, Movie Clip Start Loop Frame, and Movie Clip End Loop Frame for logic-controlled group animation.
Practical setups
Examples
Use these patterns when deciding whether to multi-select or create a real group object.
Duplicate A Machine Section
Multi-select all parts, duplicate in the needed direction, move the copy into place, then select individual objects to retune joints, trigger zones, and physics.
Animated Warning Sign
Create a group from several scene-object frames, enable Play Group As MovieClip, use Alpha or Pixelate transition, and tune each frame duration.
Rotating Decoration Around Physics
Use one physics child with several scene children, align children in Circle or Ellipse, and rotate the group so visual parts stay attached to the physical anchor.
Gear Or Star Pattern
Use Align Group Children with 5 Point Star, 4 Point Star, Circle, or Plus Thickness. Adjust X Size and Y Size until the repeated children form the intended shape.
Frame-By-Frame Machine State
Use Focus Mode with Show Previous Frame so each child/frame can be aligned against the previous one, then drive the movie frame from a trigger zone or chip.
Static Background Cluster
Group only scene objects when the cluster should be decorative and easy to move as one unit without adding extra physics behavior.
How to use it
Practical workflow
Use this flow while building or debugging a level that depends on this control.
Select all objects that should be edited together.
Use group-safe movement, scale, rotation, or duplication controls.
Check whether the selection contains mixed object types.
Some controls may appear only when the selected group supports them.
After broad edits, select individual objects for precise tuning.
Final physics, joints, paths, and game settings usually need single-object checks.
Connected controls

The selected-object toolbar is contextual, so this control usually works together with nearby controls and game systems.
