Anchor

Anchor is a simple script that keeps a Rigidbody anchored to a point where the anchor was dropped through a physics joint. It approximates the behavior of a real anchor by keeping the object near the anchored position while allowing some movement, and can drag on the seafloor if forces exceed a threshold.

Fields

• dropOnStart - Should the anchor be dropped automatically at the start of the scene
• localAnchorPoint - Point in coordinates local to the object this script is attached to. Defines where on the ship the anchor chain is attached
• zeroForceRadius - Radius around the anchor in which the chain/rope is slack and no force will be applied. This allows small movements without resistance
• forceCoefficient - Coefficient by which the force will be multiplied when the object starts pulling on the anchor. Controls the strength of the anchoring force
• dragForce - Maximum force that can be applied to the anchor before it starts to drag along the seafloor

Public Properties and Methods

• Drop() - Drops the anchor. Sets the anchor position to the current anchor point position
• Weigh() - Weighs (retracts) the anchor, allowing the object to move freely
• Dropped - Property indicating whether the anchor has been dropped
• IsDragging - Property indicating whether the anchor is currently dragging on the seafloor (force exceeds dragForce)
• AnchorPoint - World space position of the anchor attachment point on the ship
• AnchorPosition - Current world position of the anchor itself
