This is actually so simple it doesn't even deserve to be posted in the advanced section.
But as my experience proved there has been a lot of confusion about that matter these days.
What someone wants to do:
He has one var which is hundred.
He has another var which is something between hundred and zero.
still with me?
He has a scale from zero to hundred and another variable which he can place anywhere between zero and hundred as he likes:
0.......................var1...............100
0..........var1............................100
0.............................var1.........100
And that isn't very hard to make.
Now here's the problem:
He has another variable, let's call it var2.
he wants var2 to have exactly the opposite value to var1.
like this:
0..........var1............................100
0............................var2..........100
or like this:
0.var1.....................................100
0.....................................var2.100
or like this:
0..................var1....................100
0..................var2....................100
the formula is (big deal X_X):
- Code: Select all
var2 = var1*(-1)+100; // hundred can be replaced with a variable depending whether you also wanna change it.
