LookAtConstraint

Description

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

This constraint is similar to AimConstraint but is meant for constraining a Camera. Use this constraint to point a Camera towards other sources. You can also adjust the weight of each source to influence whether the Camera points more towards one source over another source.

Make sure you use LookAtConstraint properties to align the orientation of the constraint. Otherwise, the constrained Camera might point in the wrong direction.

Refer to Look At Constraint Component for more details.

// This example uses a LookAtConstraint to point a GameObject towards 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 = 0.6f };
        ConstraintSource source2 = new ConstraintSource { sourceTransform = sourceB, weight = 0.4f };

        m_LookAtConstraint.AddSource(source2);
