I'm ashamed to admit, but I have got stuck in a quite simple Maths problem.
It's all about an implementation of the basic formula y=kx+m, but somehow I have
managed to think the wrong way. Luckily, I made problems like this in a glanse
back in school...
Background; I wish to create a Tweening command.
For example:
Object.Tween Object.Progress from to start_value end_value
Minifig01.LeftArm.Angle.Tween Minifig01.Progress 0 0.25 0 40
...where Minifig01.Progress is the given x value and from and to is the other x
values corresponding to start_value and end_value on the y-axis.
So, at the from value Progress=0, we read start_value=0 degrees.
When Progress reaches the end_value=0.25, we get 40 degrees.
At Progress=0.125, the angle=20 deg's.
This is very simple, I know, but I insist on doing it wrong every time!
So, I have to humble myself and ask for the formula for this quite basic
implementation.
TIA,
/Tore
