In The Room movement sets the position of a combination mechanism’s parts. ## At a glance ![Rings and symbols in a combination mechanism](https://gamemechanics.pro/images/mechanics/adventure-the-room-03.webp) [The Room](https://store.steampowered.com/app/288160/) · Game imagery © its respective rights holders.

Rotating parts change the configuration - Map motion to a clear axis and preserve the grab point. - [The Room](https://store.steampowered.com/app/288160/) ## How it works Mouse movement is translated into a numerical value, size, angle, coordinate or shape. ## Variants ### Variants and applications - Linear slider. Action: Drag the slider along the scale. Application: Volume, power, price, length, time position. Conditions: Click on the scale and enter exact input, if appropriate. - Numerical scrubbing. Action: Drag a numeric field or label along an axis. Application: Quickly change the coordinate, quantity, size of a parameter. Conditions: Indicate the possibility of dragging; keep the normal number input. - Rotation handle. Action: Move the pointer around the center or drag along the selected axis. Application: Device regulator, synthesizer, valve, instrument angle. Conditions: Do not allow a jump at the corner transition through a full turn. - Two-dimensional controller. Action: Move a point inside the plane. Application: Color selection, two sound parameters, tactical aiming. Conditions: Label both axes and their ranges. - Resize by edge. Action: Pull the border or corner marker. Application: Windows, panels, forms, impact area. Conditions: Provide a minimum size and sufficient grip area. - Scaling while maintaining proportions. Action: Drag a handle with an aspect ratio constraint. Application: Images, models, layout elements. Conditions: Explicitly show the constraint state and anchor point. - Rotation around a support. Action: Drag the rotation handle around a given point. Application: Rotate a model, part, room, camera. Conditions: Support and possible snaps at corners must be visible. - Moving along an axis or plane. Action: Drag the corresponding part of the 3D manipulator. Application: Setting up objects, setting up a scene, designing. Conditions: Show the active axis and coordinate system. - Deformation by control points. Action: Drag vertices, nodes or handles of a curve. Application: Shape editor, route, sculpting, flexible puzzle. Conditions: Restrict self-intersections if they are not allowed. - Range with two boundaries. Action: Move start and end markers. Application: Clip trim, price range, attack interval, work area. Conditions: Define boundary crossing behavior. - Direction and length of pulling. Action: The starting point serves as a support; the vector to the cursor sets the parameters. Application: Force and angle of impact, velocity vector, direction of construction. Conditions: Display vector and length limitation. - Rotate the virtual trackball. Action: Move the pointer along the surface of a conditional sphere. Application: Inspection of a 3D model, rotation of a planet or a complex object. Conditions: This is a mathematical model of rotation, an ordinary mouse is enough. ## Context and limits Author's working classification for designing games and interactions. Options can overlap and combine; the list is not a generally accepted standard or proven exhaustive list. Application examples are conditional unless a specific verifiable observation is indicated nearby.
