This number should increase/decrease when you press up/down. I also want another counter, with the above number shown as an angle - ie. When the number exceeds 359, it should "wrap" around to 0 again. This much I can do, using the mod function in mmf. However, I also want the number in the second counter to stay positive when it goes below 0. For example, -90 should become 270. Is there a formula for calculating this? (in a single line, and without extensions). Like I said, any help would be much appreciated n/a

Sketchy Cornwall UK Registered 06/11/2004 Points 1970	25th February, 2006 at 18:29:09 - thanks, but those don't actually answer my question. the problem i have is just with keeping the angle between 0 and 359. i think i've seen it done before, but after searching here and at the clickteam forum i haven't found a solution. n/a

Sketchy Cornwall UK Registered 06/11/2004 Points 1970	25th February, 2006 at 18:39:13 - Genius! That's given me an idea; * always (or whatever) set "Counter2" to (( value( "Counter" ) mod 360 ) + 360 ) mod 360 that works! thankyou n/a
DanielRehn Registered 18/09/2002 Points 139	25th February, 2006 at 19:23:45 - why * always (or whatever) set "Counter2" to (( value( "Counter" ) mod 360 ) + 360 ) mod 360 when u can do this * always (or whatever) set "Counter2" to ( value( "Counter" ) + 360 ) mod 360 less code! n/a
Sketchy Cornwall UK Registered 06/11/2004 Points 1970	26th February, 2006 at 00:26:57 - Thanks for the suggestion, but that wouldn't work if counter1 went below -360 (if you turned more than one full turn anticlockwise, which is quite likely after a while). You'd start to get negative answers again; -400 for example, would produce the answer -40. The first mod puts the number in the range of -360 to 360; adding the 360 then shifts the value into the range 0-720 (so no negative values); the second mod then puts the number in the range 0-360, which was the aim of the exercise Edited by the Author. n/a

DanielRehn Registered 18/09/2002 Points 139	26th February, 2006 at 12:15:40 - Sorry...did'nt se that you were using two counters... If you only use 1 this will work... since the moment it goes below 0 (eg -1) it will add 360 (359 then)... n/a
Sketchy Cornwall UK Registered 06/11/2004 Points 1970	26th February, 2006 at 20:49:30 - CUBE: That's 2 separate events, so you couldn't use it as part of a more complicated formula. I may or may not use two counters (that was just me trying to explain the problem as clearly as I could), but I always prefer to do stuff in the minimum number of events anyway - it's more "elegant", and in theory, it'll make your game run quicker too.

But then again, I'm not entirely sure of what you are trying to do, so I guess it wouldn't work under some conditions. Craps, I'm an old man!
