The "operation" patch – don't touch the edges! (re my onebang gripes)

Used for cheap gesture detection. Includes Peter McCulloch’s fantabulous onebang patch.

The general idea is to wait until the cursor moves all the way to the left. Once that happens I wait until I get "far enough" to the right and then draw a rectangle across the entire area of operation, whose height is equal to (cursor position +/-5). As long as I stay in the rectangle and get "close enough" to the right edge, the whole system sends a bang. If I leave the rectangle before I get to the right edge, the system locks until I go back to the left.

Switching directions and making a vertical rectangle should be trivial.

Yes, I know I’m doing some things wrong probably, but this is what I mean when I say that sacrificing flexibility for speed often results in reduced speed. For example, I’m positive that the ggate is being used incorrectly. Likewise I really shouldn’t have to connect to both inlets of the messageboxes. However, overall I think the patch is far messier than it has to be. For instance there has to be a better way of doing the last 2 operations (+>sel2>).

Also – see how the cursor leaves the lcd completely in the bottom right corner? Can I fix this? I assume this is because I drew the sprite wrong.

Many thanks in advance
