BRAINTEASERS
By G. Ludinski
PART two of EUG's series of utilities designed to stretch your brain
into all manner of putty-like shapes presents another two of the same;
once again with this accompanying article divulging their secrets.
Brief instructions also appear on screen.
A-MAZE-ING
YOU are in the middle of a complicated maze, and your objective is to
reach the outside in the quickest possible time, but also with the few-
est number of moves possible.
Don't rush headlong into this one as a little forward planning can
save you time and points.
Every step counts as a point and every time you try to cross a
barrier counts as a point.
You must aim for the top right hand corner or the exit nearest to
that one.
How to play
YOU are represented by a dot in the lower left hand side of the maze,
and you move by using the ARROW cursor keys.
Your score will be displayed at the top of the screen. The number of
steps taken has a greater effect on your final score than the time
factor.
You may, of course, retrace your steps and begin again from any point
you wish to. When you have reached the outside, or you wish to give up,
press the <ESCAPE> key.
We hope you make it, as there are plenty more 'Brainteasers' waiting
for you on the outside.
Programming hints
THE maze is created of cells, each of which have one side blocked off.
The cell shapes are drawn using VDU 23 to create user-defined graphics.
You could increase the size of the maze by changing 20 and 24 in
lines 230 and 250. The maze shown is 24 columns wide by 20 rows. The
maze shown is 24 columns wide by 20 rows. The maze array M% must be
DIMensioned 1 column and 2 rows larger than the actual array to allow
for checking the (X+1)th column and (Y+1)th row. If you want the array
in the centre of the screen you should change the PRINT statements in
lines 220 and 240.
The lines drawn down the side of the maze in lines 300 and 310 would
have to be changed, so would the start position of the dot in lines 320
and 330. In a 20 row maze, the 21st row is the row the dot starts on,
so special conditions apply to this row in lines 370 to 430. If a diff-
erent number of rows is chosen this 21 must be changed.
SPOT THE DIFFERENCE
I SUPPOSE that this could have been called STARS AND STRIPES, the
difference as you will see when you run this colourful eye test.
Two pictures, composed of stars and stripes, in red, white and blue
appear on the screen, and you will be asked to identify which of the
items is different.
How to play
ITEMS are keyed as follows:
Red Stripe = 1 * White Stripe = 2 * Blue Stripe = 3
Red Star = 4 * White Star = 5 * Blue Star = 6
Identify the differences and key in the number and press <RETURN>. If
you are correct you will hear a high pitched tune, but if you are wrong
your answer will be crossed.
To help you, numbers previously keyed in are displayed in brackets.
When all the numbers required have been keyed in a further tune will be
played. Just hope that it is high pitched for a correct answer.
To continue, or stop, press Y or N or <RETURN>.
At conclusion you will see your score sheet showing tries, correct
answers and time/average taken.
Programming hints
YOU might find the routine PROC_STAR useful in your non-commercial
programs as it draws a star. You just have to specify the bottom left-
hand corner of the star (X,Y), the width of the bottom of the star (W),
the height of the star (H) and the colour that it is to be displayed in
(CL).
You could make the puzzle easier by increasing the range of possible
values for the shapes that are going to be different. The function
FNM(MIN,MAX) is used to define the minimum and maximum value of any
shape. Remember if you increase the MAX value you must reduce MIN by the
same value, or the picture will extend beyond the allocated area.
