Constraints are powerful tools in Rive that allow one object's properties to be controlled by the properties of another. They can be used for simple tasks like syncing positions or for complex behaviors like creating IK systems and making objects follow paths. Constraints also provide the ability to limit or restrict an object's movement and scale.
- Property Linking: Constraints are essential for maintaining relationships between objects that aren't in the same parent-child hierarchy.
- Automation: They reduce the need for manual keyframing by automating motion based on the behavior of other elements.
- Performance: Like other Rive rigging tools, constraints are designed to be extremely lightweight and performant in real-time.
