DPT_RopeAnchor

Component Reference Guide
A lightweight, procedural anchoring utility designed to mathematically stretch and orient cosmetic linkages (ropes, chains, tension bands) between static bases and animated target points, bypassing the need for rigid animation scaling.

Inspector Property Configuration

Rope Anchoring Array

Processes an array of RopeAnchor blocks targeting distinct structural connections within the prefab hierarchy.

Property	Description
Rope Label	A descriptive text string used to organize and name array entries within the Unity Inspector layout for easy modification.
Rope Base	The scene reference to the static start point of the rope. Any visual geometry (including `LODGroup` meshes) must be nested directly under this transform. The script applies all calculations to this parent object.
Target Anchor	An empty target transform nested inside the animated moving structure (e.g., a throwing arm). The script uses this spatial coordinate to calculate real-time distance and rotation vectors.
Length Axis	The local axis (`X`, `Y`, or `Z`) that runs exactly down the modeled length of the assigned rope mesh. The script mathematically aligns and stretches this specific axis to bridge the visual gap.

Technical Architecture

Independent Execution Loop: Operates entirely decoupled from the primary weapon tracking scripts. Evaluates exclusively within its own LateUpdate call, ensuring that rope orientations perfectly track target anchors after the Unity Animator has finalized its frame positioning.
Automated Distance Caching: On Awake, the script automatically reads the authored distance between the base and the target anchor inside the prefab. This eliminates the need to manually input resting length variables; the script simply scales the axis proportionate to that starting distance.
LOD Group Compatibility: Because spatial manipulations (LookAt routing and Axis Scaling) are applied directly to the designated ropeBase transform, nested geometry structures like LODGroup hierarchies are inherently supported without requiring custom renderer references.

Troubleshooting Notes

"My ropes are scaling into flat shapes instead of stretching toward the anchor"

Ensure that the Length Axis property perfectly matches the local axis along which your rope mesh was modeled. If your 3D model is aligned along the Z-axis but the script is instructed to stretch the Y-axis, the mesh will flatten or stretch in the wrong direction. Simply change the dropdown to the correct axis to resolve the issue.
