I'm starting to experiment with the joy_rot/raw values, and I tried the example in the manual for keeping the throttle within a 0-100 range. Mathematically, it's perfect, but I can't seem to get it to work.

Here's the Code:

---

#include <acknex.h>
#include <default.c>

fixed throttle;

PANEL* _joydiag=
{
	digits(512,364,"joyX= %1.0f",_a4font,1,joy_raw.x);
	digits(512,384,"joyY= %1.0f",_a4font,1,joy_raw.y);
	digits(512,404,"throttle= %1.0f",_a4font,1,throttle);
	flags= VISIBLE;
}

void main()
{
	video_mode= 8;
	video_screen= 1;
	screen_color.red= 1;
	wait(3);
	while(1)
	{
		throttle= 50 - (50 / 255) * joy_raw.z;
		wait(1);
	}
}

As you can see, it's a very simple test program that merely shows the values of the joystick axes. I don't understand why the red part is showing 50 instead of what the actual value should be.

Could it be an error elsewhere?

It probably means that your joystick is not registering the joy_raw.z values.
Is it showing changes in the x,y values ?
The code looks perfect to me.

Hi MrCode,

mathematically everything is ok.

But (50/255) is always = 0 because they are integers and will be rounded (0.19 = 0)

If you write (50.0/255.0) then it should work.

ok, everything seems to work now.

@Conitec: It would be great if you could implement the ability to use different data types for PANEL* items, instead of just fixed (var).
