ScaleConstraint

Description

Constrains the scale of a GameObject based on the scale of one or more sources.

Use this constraint to scale a GameObject based on the scale of other sources. For example, use this constraint to scale UI elements based on the scale of a viewport. You can also adjust the weight of each source to influence whether the constrained GameObject follows the scale of one source over another source.

Refer to Scale Constraint Component for more details.

Additional resources: ConstraintSource, RotationConstraint, PositionConstraint.

// This example uses a ScaleConstraint to constrain the scale of a GameObject based on two sources.
// The first source has a greater influence than the second source based on their assigned weight.

        ConstraintSource source1 = new ConstraintSource { sourceTransform = sourceA, weight = 0.7f };
        ConstraintSource source2 = new ConstraintSource { sourceTransform = sourceB, weight = 0.3f };
