It turns out that the Belkin Nostromo n52 is ODD insofar as it seems to be about the only
game controller I can lay my hands on that Xubuntu automatically recognises and receives
key signals from.

The Belkin Nostromo n50 doesn't work; nor do the gamepads and steering wheel with pedals thing I have.

I would be most grateful if an expert (Richard Gaskin ?) could explain what stops other USB devices
not having their keyDown/Up signals being recognised both by Linux, and by Livecode-on-Linux
while the Belkin Nostromo n52 effectively behaves exactly like a keyboard.

This one does exactly what it says "on the packet".
As well as demonstrating how to use SWITCH and CASE.

One of the boys attending my Summer classes proposes to produce a searchable map of somewhere for
his final project. How he will manage that I just don't know as he seems very good at copying code,
but unable even to adapt copied code for his own ends.

In talking to him it became clear he was proposing to "rip off" a map stack I made last year
[as such, I have no objection to that]

and JUST change the map.

So, being the "nice chap" that I am, I came down on that one like a ton of hot bricks, and told him
that if he wanted to do something with maps he should add a new feature that isn't there in my stack:
otherwise "no marks, no diploma, and cast into outer darkness forever".

Anyway, this weekend, fueled by drinking rather too much coffee, I began to wonder about this boy's "plans" and
wondered how easy it would be to make a searchable map. Well, face it, loads of other people have done this; starting with
the dreaded monopolising Google downwards.

So, here is my way of doing things: it's very simple indeed because nobody helped me
[ well, possibly the people who make Tchibo coffee (commercial endorsement) ],
and it should be considered a prototype.

Not all the places in Kirkwall [my favourite town in Scotland] are listed. Pop open the red disclosure
triangle to see what's going on.

Things I would change:

1. Probably better to have a drop-down menu populated with street and feature names rather than a search field.

2. The scaling of the map and the magnifying glass are "all wrong".
Here's the stack (6 MB): https://www.dropbox.com/s/8bo5un6psbvwj ... e.zip?dl=0

Well; I've just been fiddling around and "done" a version with a drop-down menu:

For anyone who is wondering about the "Saint Olay Chapel" . . .

Patron saint of skin-care products:

[That is "revenge" for the drop-down menu dropping upwards.]

This is my "map kit" for anyone who wishes to try making a navigable amp:

We looked at the uses of Blend/Ink:

Time to "hit them" with Unicode text.

We're going to have fun building an old-fashioned Bulgarian typewriter:
The stack has only got functionality for 3 buttons: ѩ, DEL & CLEAR, and 'something' in the cardScript.

Everyone will need this for reference: http://www.unicode.org/charts/PDF/U0400.pdf

introducing overlay, opacity and numToCodePoint.

It is useful to contrast the use of ink.

This is the first stack to show you how LAYER can be used to achieve various optical effects:

Check out your Early Middle English:

Svmer is icumen in
Lhude sing cuccu

Bulluc sterteþ

murie sing cuccu
Cuccu cuccu

Sing cuccu nu • Sing cuccu.
Sing cuccu • Sing cuccu nu
Look at the words "bucke uerteþ" = "buck verteth" a bit more closely.

And here's a companion stack to the LAYER one to play around with mouseEnter,
mouseLeave, mouseDown, mouseStillDown and mouseUp to achieve various optical effects:

Today one of the children mentioned "Tank Wars":
so we got "all hot and sweaty" about how to do something like that in Livecode:

So, it occurred to me that we needed to generate a parabolic trajectory graphic for cannon balls to fly along:

Obviously that will have to be flipped vertically before it is used in a game.

Really nice posts, thanks for sharing.

This may help you with some 'specials' to your last project.
