Direction vs Counter

[polymonsta]

Hi all!

I have a problem. I put an active object with 32 directions.
There's a counter to display the object's current direction.
How can i set the counter to 0 when the object's direction is "up"?
Everytime the "up" direction is 8, and the "right" is the 0. Why?
It worked well in the Klik&Play but i haven't got any solution in the MMF2.
I hope you understand my problem, and sorry for my bad english skills.

cheers,
p

In MMF 2, the "starting" direction, which faces to the right, is zero. Top/right is 4, and directly up is 8. MMF 2, is providing you with correct information when you understand what it considers to be zero (right facing).

The numbers for each direction look kind of like this:

12 8 4
16 0
20 24 28

thx for the reply!
i know the logic of the mmf2, but i don't know the solution.
i'm trying to make a little drum machine with pots, and its important to get the 0 when the direction is "up".
i can set the counter on each direction, but that's not the best.

Start of frame,.. set animation direction to ----> Equals Zero. Or if you would like to upload your mfa, we can take a look at it for you if you are stuck. Also you could set the counter to direction minus 8.

Alway ---> Set counter to "Dir('Active)" -8

So, you want to redefine 0 as up, left as 8, down as 16, and so forth? I can't understand why.

Anyway, I think ProdigyX is basically right with a small change.

if the direction value of the object >=8 ---> Set counter to the dir value of the object -8
if the direction value of the object <8 ---> Set counter to (the dir value of the object -8) + 32

I think that's how it works. If you just subtract 8 from the value all of the time, you will sometimes get a negative direction value such as 6 - 8 = -2. Adding 32 should make it 30. Otherwise, a negative direction in MMF 2 will cause a tear in space time.

forgot something and its important. the counter's minimum value is 0 because i'm making a synthesizer project, and if the counter is negative the sound generator don't work.

My directions should always give you a positive number. Try it out.

thanks man, its working
but there's another problem, how can i invers the counting? i mean, the "up" is 0 and the next directions to right are +1?

I wonder if we're re-inventing the wheel.

Okay, add this:

If counter is > 0 and < 16, then set the counter to 32 - counter value
If counter is > 16, then set the counter to 32 - counter value

So, with the direction being adjusted with the actual direction value of 8 (up), now equal to 0, let's test it. An adjusted value of 8 would turn out to be on the opposite side of the circle at 24 (32-8=24).

Try it out. My brain hurts. I was sorely tempted to just say, for example if direction = 16, then set counter to 8. Then repeat the whole process 32 times.
