i'm making a flight sim, but with the throttle my joysticks is reverse. so at o% it reads 1000 and at 1000% it reads -1000, how can i get it so that 0%=1000?

you do 1000 - what the actual reading is...

1000 - 0 = 1000

1000 - 1000 = 0

So that has now reversed the result.

Pincho is almost correct but not quite. Since you are going from 0 to -1000 if you subtract -1000 from 1000 the result is 2000, a minus, minus is a plus.
You will need to use abs() to remove the negative value first.

So Throttle = 1000 - abs(Joystick Slider a())

thnx 2 all of you, i sorted it out, all you do is:
throttle#=(joystick slider a()*-1)+1000

1000(which is 0 throttle on my joysticks)*-1=-1000
then add 1000=0

-1000(which is 100% throttle)*-1=0
0+1000=1000

thanks n e way

My method involves less calculation and will therefore be quicker.
Another option, again using less calculations is:
Throttle = 1000 + Joystick Slider a()

1000 + 0 = 1000
1000 + -1000 = 0

the only problem with that is that joystick slider a() ranges from -1000 to +1000 not 0 to 1000. but thanks anyway!

Well my method is to get the throttle to work is simply this

if joystick slider a()=0 then move object 2,10
and to move backwards
if joystick slider a()=65535 then move object 2,-10

that works ok for Saitek X36 USB (once you sort out the caliberation on it)
and the The Thrustmaster Afterburner series of joysticks(I know I got all three of the range)

That will work for ground or flight vehicles

Hope I was of help

the only problem is that i'm using advanced flight dynamics so moveing an ojbect isn't the only thing to do, the throttle must be processed etc.

this thread can now be locked
p.s thanks 2 everybody 4 their support
