Generally, I don't use repeat or while loops for animation, since they
make
the animation dependent on the speed of the CPU rather than the
framerate or
any user-defined speed setting, and they tie up the CPU preventing
frames
from advancing normally for everything else in the movie. When I do
animations that are all lingo driven, I usually set the movie framerate
high
and govern the speed of sprites using "the ticks" or "the milliseconds".
For example, make a movie with a high framerate (like 999) and give a
sprite
this behavior:
----- Code starts here
property pNextMoveTime, pInterval
on beginsprite me
pNextMoveTime = the ticks
pInterval = 20 -- move no faster than every 3 ticks
end
on enterframe me
if (the ticks>=pNextMoveTime) then
sprite(me.spritenum).locH = sprite(me.spritenum).locH + 1
pNextMoveTime = the ticks + pInterval
end if
end
----- Code snip ends here
Setting pInterval to 0 will move the sprite on everyframe, as fast as
your
framerate or as fast as your computer can do it. But setting pInterval
to 1
will give you a movement of 60fps so long as your movie framerate is set
significantly higher than 60 and your machine is keeping up. Bump
pInterval
to 2 and you get movement 30 times a second and so on. If you have a
very
fast machine and need finer control than 1/60th of a second chunks, you
can
also use the milliseconds global in the same manner.
