NetLogo Help: tie

### tie4.0

#### tie

Ties end1 and end2 of the link together. If the link is a directed link end1 is the root turtle and end2 is the leaf turtle. The movement of the root turtle affects the location and heading of the leaf turtle. If the link is undirected the tie is reciprocal so both turtles can be considered root turtles and leaf turtles. Movement or change in heading of either turtle affects the location and heading of the other turtle.

When the root turtle moves, the leaf turtles moves the same distance, in the same direction. The heading of the leaf turtle is not affected. This works with forward, jump, and setting the xcor or ycor of the root turtle.

When the root turtle turns right or left, the leaf turtle is rotated around the root turtle the same amount. The heading of the leaf turtle is also changed by the same amount.

If the link dies, the tie relation is removed.
