THE THIRD DIMENSION

Sound and Light effects by Tony Hartley.

I have included Four demos on how to use sound samples and how 
to produce special effects this month using kit 2.PC owners can 
use the example text provided below to make their own demos with.
Atari/Amiga owners can load the demos to see the effects.Once you 
have loaded a demo,you should then load the sample bank 
called- SAMPBANK.3SM as well. 
 
CAR.3WD shows the use of sound and flashing lights used to create 
a police car.This just uses Fadebounce objects for the lights 
combined with a siren sample.These are placed in a Local 
condition.E.g.-
FADEBOUNCE (16)  fade the blue flashing light object
FADEBOUNCE (14)  fade the red flashing light objeect
FADEBOUNCE (4)   fade the headlight object.etc
SOUND (4)        play siren sample

CRANE.3WD shows you how to produce a sky that gradually darkens 
to nightfall then back to daylight again.It is called Crane.3WD 
because it features a big mechanical digger.
Here is the routine that you put into a LOCAL CONDITION.You can 
cut this text out if you wish then save it off on its own then 
place it straight into kit 2.The setsky colours are the colours 
in the Object colour palette numbered from left to right starting 
with number/colour zero.If the effect works too quickly/slowly 
then adjust the last number in the 'FOR (V34,0,8)' line up or 
down.If you want a more gradual effect then add a few more 
'For/wait/next/setsky' commands. 

FOR (V34,0,8)

HORROR.3WD shows you how to achieve a thunder and lightning 
effect.The demo shows a haunted house on a hill.
Here is the routine that you put into a LOCAL CONDITION.You can 
cut this text out if you wish then save it off on its own then 
place it straight into kit 2.The setsky colours are the colours 
in the Object colour palette numbered from left to right starting 
with number/colour zero.The sound(5) is a typical thunder sample.
