Distance Constraint

Summary

The Distance Constraint establishes a specific physical distance relationship between two objects. It can be used to set a maximum, minimum, or exact distance, allowing objects to be dragged or pushed based on these spatial boundaries.

Step by Step

1. 00:26
   Adding the Constraint

   Select the object you want to constrain (the owner), navigate to the Constraints section in the Inspector, and add a Distance Constraint.
2. 00:33
   Visual Distance Indicator

   Observe the red guide circle that appears; this is a visual aid representing the current distance value.
3. 00:45
   Adjusting Distance

   Modify the Distance property in the Inspector to increase or decrease the radius of the constraint zone.
4. 00:59
   Setting the Target

   Use the target selector to choose a second object. The distance indicator will snap to this target's location.
5. 01:50
   Configuring Modes

   Choose between three modes to define the behavior:

   • Closer: The owner can move within the distance but is blocked from moving further away (maximum limit).
   • Further: The owner can move away but is blocked from moving closer than the set distance (minimum limit).
   • Exact: The owner is locked to a precise radius around the target, unable to move closer or further.

   Practical Application

   Use these modes to create mechanics like pupils staying inside an eye or objects being tethered to each other.

Notes About Current Rive

• Interactive Physics: The Distance Constraint is ideal for simulating physical boundaries without complex coding, such as keeping a UI handle within its track.
• Guide Visibility: The red circular guide is only an editor aid and will not appear in your final exported Rive file.
• Target Dynamics: When the target moves, the constrained object will be "dragged" or "pushed" to maintain the rules of the selected mode.
