Learning Ink

 

Ink is a scripting language for creating interactive fiction like choose-you-own-adventures and other vast, branching stories.


 

Tunnels

In Ink, it can often be useful to a create knot that is returned to multiple times throughout a flow. Instead of a complex series of diverts and knots, Ink has functionality to quick go to a knot and then return called a tunnel.

As it names implies, tunnels are connections between sections where the flow is diverted to a knot or stitch and then returns again. The player passed through the “tunnel” and out the other side back to the same or different place.

Tunnels are created using the divert (arrow) to “go to” a knot or stitch and then a second divert after the name of the knot or stitch.

1_Tunnel

To return from the tunnel, use two divert symbols in a row. This will “twice divert” back to the original location.

Threads

In some ways, threads are the opposite of tunnels and using diverts. Instead of “going out”, threads “pull together” knots and stitches as part of a flow. To use threading, the arrow changes and points in, “<-“.

2_Thread

Using threads helps separate knots into logical sections of code for the author and developer and then “thread” them all together again.
