Actor Facing Direction

PaxPax

I am struggling with this easy issue and have finally decided to let my bruised ego ask for assistance. I have a clock. The small arm of the clock rotates with a touch behaviour. I cannot figure out how to detect when the small are is facing numbers on the clock. For instance, I would like the sound 'three o'clock' to play when the arrow/small arm is facing the three and so on for each number. How do I detect where the arrow/small arm is facing.

Thanks and cheers!!!

if self.rotation is 90 (for example) than play sound..... to no avail.

I guess because you are making a clock your arms are going clockwise (axiomatically!) - so in GameSaladLand™ going clockwise is actually decreasing the angle (counterintuitively counterclockwise counts up in positive value / clockwise counts down) . . . so:

12:00 is 0°
3:00 is -90° (or +270°)
6:00 is -180° (or +180°)
9:00 is -170° (or +90°)



I've made you a quick demo:

3 o'clock = 270°
6 o'clock = 180°
9 o'clock = 90°
12 o'clock = 0°

3 o'clock = 270°
6 o'clock = 180°
9 o'clock = 90°
12 o'clock = 0°


Woh, now my ego is really bruised.
I should have articulated my question in a more concise manner. What is the 'code' for the arm/arrow to recognize its rotation degree---3 o'clock or whatever. I tried...

if self.rotation is 270 (for example) than play sound..... to no avail.

thanks again and as always, Socks, thanks for making me LOL

PaxPax

Thanks @socks---finally worked. It was one of those weird out of body experiences as I had played round with 'negative' degrees, clock wise and counter clock wise etc. The attribute to set self rotation back to zero really helped!!! I am sure I would have forgotten to do that as well.

Thanks again,

Socks

It's a rule rather than an a attribute. [/pedantry] |) 8-X :P

There's probably a more efficient way you could do it without that extra rule - (maybe using %360 ?) - but the demo should hopefully give you a few pointers.

PaxPax

Yes, as you say it is an attribute. However to continue with this pedantic behaviour, in this case it is an attribute within a rule. Am I forgiven for me unscholarly or informal communication? @-)

Socks

Yes, as you say it is an attribute.

No, I said the very opposite, I said it's a rule rather than an attribute.

Here is a fun formula that will give you the hours:
floor((12-(self.Rotation-90)/30)%12)

And here is one for minutes:
floor((60-(self.Rotation-90)/6)%60)

Note: the clock hands should point to 0 degrees when drawn --->
