Ropesight has an important role to play too, mainly providing assurance that you are in the right place, but also providing some useful (if imprecise) hints about the striking that is about to be heard. The problem with ropesight is that it is difficult to learn. Traditionally it has only been practical to teach and practise ropesight in the tower, in a live situation, at full speed, with imperfect striking and the mistakes of others confusing the picture.
Virtual Belfry attempts to help develop this visual skill, providing the equivalent of a helper standing behind you and pointing at the ropes you are supposed to notice. You can practise at home. You can slow the action down. You can stop and start again in an instant. As a teacher you can use it to demonstrate the concepts involved in ropesight.
There are several options for ropesight practice, the main ones being "flashes", "cumulative", and the ropesight game.
The aim of this mode of usage is to draw your attention to the rope you are about to follow at about the time that it would be noticed in the tower. This is achieved by flashes of colour that appear momentarily around a sally as it is moving.
The flashes occur just after your own bell has struck. You can vary the timing of the flashes to guide your eyes to the correct rope immediately or to give yourself time to try to spot it before the flash gives you confirmation.
No flashes occur while you are leading. Flashing the last rope to fall (which is the one you would normally expect to notice while leading) did not seem to be as convincing and helpful as the other flashes. This is something that might be introduced in a later revision.
The aim of this mode of usage is to illustrate the way in which ropes are "collected" while hunting from the lead to the back, and then "discarded" when hunting back down again. When you are leading you are following no ropes at all. When you are lying behind you are following (i.e. ringing after) all the other ropes. So to hunt from leading to lying you must ring after one rope, then two, then three and so on, collecting more and more ropes as you hunt towards the back. To hunt from the back to the front you must discard all the ropes you collected while hunting up, one rope at a time.
When hunting up, ropes that you have collected stay collected. The next rope you will collect is the one that is immediately following your own rope. After you have collected a particular rope, you no longer need to consider it when looking for the next rope to collect. The nearer you get to the back the fewer and fewer ropes there are left to consider.
When hunting down, ropes that you have discarded stay discarded. The next rope to discard is the one that you are following. After you have discarded a particular rope, you no longer need to consider it when looking for the next rope to discard. The nearer you get to the front the fewer and fewer ropes you have remaining in your collection.
