{C#} How to pin an entity to a wall using a rope?

[jeffsturm4nn]

I've tried to do that in many ways but it just doesn't work. Here's the portion of my code that create the entity-wall hook: 

 

//hookPoint -> where the rope is attached on the entity (i'm using raycast to get the entity that the player is aiming at and where he's aiming at).
//mapPosition -> the point in a wall (somewhere in the map) where the rope will be attached.
//HookGroup -> it's just a struct-like class that contains two entities.

private HookGroup CreateMapPositionHook(Entity entity, Vector3 hookPoint, Vector3 mapPosition, RopeType ropeType = (RopeType)3)
        {
            if (entity == null)
                return null;
			
            Vector3 hookOffset = hookPoint - positionPair.first;
            Vector3 entityPosition = entity.Position + hookOffset;

            float ropeLength = entityPosition.DistanceTo(mapPosition);
			
  			//These three lines below is where the problem is. It works perfectly with two entities of any type but it doesn't work at all when i try 
  			//to connect an entity to a position in a wall in the map.
            Rope rope = World.AddRope(ropeType, mapPosition, new Vector3(0,0,0) , ropeLength, MIN_ROPE_LENGTH, false);
            //rope.PinVertex(rope.VertexCount-1, mapPosition);
  			//If i use Rope.PinVertex, the rope attaches correctly in the wall and on the entity but the physics stop working and the rope gets stretched forever
  			//when the entity moves >.<***
            rope.ActivatePhysics();
            rope.AttachEntity(entity, entityPosition);

            entity.ApplyForce(new Vector3(0, 1, 0));

            HookGroup hookGroup = new HookGroup(rope, ropeType, entity, null, false, true);
            hookGroup.hookPoint1 = entityPosition;
            hookGroup.hookPoint2 = mapPosition;

            return hookGroup;
        }

Since there's no documentation for the ScriptHookVNet, i'm totally lost. Please help T.T
