Hello,

I would like to know how to program a line of code that when my first value (x) decreases, my second value (y) increases in a constant ratio. It should be in the ratios like so:

X : Y

100 : 0.15

50 : 0.3

0 : 0.45

Any help is appreciated.

Thank you.

the easy way to do this is to use Properties when setting a value of first change the value of the other

if x is always going to be between 100 and 0 you could implement Y as a simple property

public float Y

{

get

{

return ((100 - X) * 0.003f + 0.15f);

}

}

One way could be using InverseLerp.

```
private float x;
private float y;
public float X
{
get { return x; }
set
{
float tx = Mathf.InverseLerp(0f, 100f, value);
y = Mathf.Lerp(0.45f, 0.15f, tx);
x = value;
}
}
public float Y
{
get { return y; }
set
{
float ty = Mathf.InverseLerp(0.45f, 0.15f, value);
x = Mathf.Lerp(0f, 100f, ty);
y = value;
}
}
```

You could use an AnimationCurve. Itâ€™s by far the easiest way to handle arbitrary value mapping.
