Please someone with a working brain explain this!

Ok.... i am wanting to rotate an object between 50 and 130 but the rotation is like in reverse.. well it goes 50 to 360 to 130 if you understand me! which is why its making it very hard to do what i want to do!

I want to control the angle between to lower values like 0 to 30 but STILL have the angles above!

So.. 0 value would set the angle at 50 (min)
and.. 30 value would set the angle at 130 (max)
and then .. if the value was at 15 the angle would be in the middle of 50 - 130 (bearing it mind it goes from 50 to 360 then down to 130)

How can i do this???

Thanks
Andy

I don't understand you, but you might want to do something like: angle = 50 + ( value * 2.666667 )

Ok, what does that do then?

ok, i see what it does, but to get it to move the range i want it to, i have had to *9 but! that then litrally only gives me like 30 points of angle!

how can i keep it smooth so when rotating its not 30 leaps! but a nice smooth rotation 1 angle at a time?

Cheers

Well...excuse my not-knowing-ness, but my understanding of this is that you want something, basically, to go 1->3->2. If my understanding is correct, then you might want to make an event that, "when alterable value = 1, rotate "(object)" to (degree) degrees. Then, make the angle change from 1->3, and set the value to 1 when it's completed. Basically, "active"->rotate 180 degrees->set alterable value 1 to "1"-> which triggers the event, "rotate "active" -90 degrees. I hope this helps, if not, I'm technologically inept. :crazy:

Well, ive managed to make it now so if for instance i press the up button it takes the angle from my min to max!

But to do this ive had to do angle = 50+(counter*9) then the up and down key just ads 1 or subtracts 1 from the counter from 0 to 30! and that works! BUT because im *9 it rotates in large steps! infact.... its moving at like 9 angles in 1 change!

So 1 up press rotates it now 9 angles in 1 :(

What im trying to achieve is like it is now so i control the angle 50 > 360 > 130 from the value range of 0 to 30 but still have seemless rotation! So somhow it works out the angles in in between! So instead of jumping 9 angles at a time it still moves at 1!

I think ill have to make an example as it seems its little hard to explain and understand! :D

instead of creating an example just list the inputs and outputs

Ok..

Its a dial, imagine a speedo on a car! Its like that!

So the needle when at 0mph is down towards the bottom left! (angle = 50)

It goes right round to bottom right (angle 130)

BUT it goes up around which means the angles go 50,49,48,47..ETC to 360 then 359,358,357.. down to 130 then back again!

so theres actually 280 angles ( 50+(360-130) = 280 ) But i want to keep them amount of angles but control them using a counter with a range of 0 to 30.

so (counter=0 ,angle=50) and (counter=30, angle=130)

When i press the up key it ADDS 1 to counter but sets the angle accordingly.

I do currently have it working like this by simply:

Key up pressed > at 1 to counter
Key down pressed > subtract 1 from counter
Allways set angle of object to 50+(counter val*9)

This then moves the needle from 0mph to max mph and back again, but its moving the needle in steps of 9 angles at a time because i am *9! i still want it to move smoothly, not in big steps?

hope this helps

For 0...30:
50 down to 0
Instead of -1 jump to 359
359 down to 130
Instead of 129 jump to 50

?

Hmm not really understanding the above? but ill explain it differently!

This is how it is: I have a value coming into my mmf2 app from a third party source. It varies from 0 to 1.5 but the increments are 0.01,0.02,0.03 ETC so when it gets to 1.5 in total there are 150 increments in total!

I need them 150 increments to correspond to the angles i am trying to get! so angle 50 is min and 130 in max, bareing in mind it goes from 0 > 360 > 130 and likewise in reverse!

so theres 150 increments and 280 angles! (not enough incremnts but that cant be changed!!)

Do you understand my problem?

Thanks
Andy

just go down instead.
Set the angle to 50 - speed.
Will go 50, 49, 48, ... 1, 0, -1 (359), -2 (358) ...
?

I understand that! but like i said above the value coming in has 150 different increments! i need to move it 280 angles! using 150 different values?

how?
Cheers
Andy

well, I probably did not understood but cant you multiply your increment by 100 so 0.01 would give 1 , 0.02 woud give 2

then set the angle to this value.
(dont get the 130 story ???)

Add *280.0/150.0

Right ill try that!

jpcr: 130 is the final angle i want to get to.

Hmm dynasoft.. dont think thats going to work? 150 isnt the number, thats just how many different increments there are.

Right here it is, the value thats coming into my ap VARIES al the time from 0 to 1.5 moving in incremnts of 0.01 at a time!

I need that value to always set the angle of my active object between 50 and 130! (but with angle goind DOWN so 50 > 0 > 360!)

am i to create an example or is the above more understandable?

its like if it was put in a table it would be like

value : 0.00|0.01|0.02|0.03|0.04|0.05|0.06|0.07|0.08|0.09| 0.10 ..
Angle : 50 | 49 | 48 | 47 | 46 | 45 | 44 | 43 | 42 | 41 | 40 ...

now if that table was to keep going it would stop with the VALUE at 1.5 (the max it can be) but the angle would only be at 100 and i need the angle to go up to 130 so when the VALUE is 1.5 the angle is 130! So it likes spreads the angle evenly between the values somwhow!

Understand that?

Its ok ive done it! :D i think!

I had to set the angle to 50-(counter_value*180)

Cheers all for attempting to understand me tho! :)
