EntityLinkManager

About Managed Links

What happens when a component refers to an entity and that entity gets deleted? A mess! This optional module will manage your entity references for you and can deal with complicated relationships easily.

public class Anchor extends Component {
    @EntityId public int target = -1; // managed
    public Entity target2;            // managed
}

Uses

• Prevent dangling references to entities.
• Remove referencing components when target entity dies.
• Remove child entities when parent dies.

Limitations

• Requires the field itself to be public. A private field with getter/setter is currently not supported.
• When using kotlin, coerce it to a field by adding the @JvmField annotation. (see https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.jvm/-jvm-field/)
