Add or Subtract a variable[Solved]

[Akarillon]

Hello again everyone

I still come back here for some more guidance.

I have a big pile of variables/constants that I need to be selected depending of the previous variable/constant.

Something like this:

Global $pos[1][4]
$pos[0][0] = 35, 30
$pos[0][1] = 110, 30
$pos[0][2] = 185, 30
$pos[0][3] = 260, 30
If $variableA = yes Then
  $pos[0][2] = $pos[0][2] - 0.1
EndIf

This clearly wont work, but is more of a suggestion to what I want to happen.

The outcome should then be $pos[0][1]

Is this possible?

Kind Regards,

Akarillon

Something like this maybe?

$Y=2
If $variableA = yes Then
  $Y = 1
EndIf
$pos[0][2] = $pos[0][$Y]

Your explanation for what you're looking to do isn't very clear.

Or maybe like this?

If $variableA Then $pos[0][2] = $pos[0][2-1]

Edit: Is $pos[0][2] supposed to be 110, 30 (the same as $pos[0][1]), or 185, 29?

Hmm.. didn't think that would work inside a variable

Thanks and I dont really know how to make the question that much clearer :S

It is supposed to be the lower variable aka $pos[0][1]

I also need 1 more important thing.

The numbers inside, [0][1] needs to be something that I can read and then take the current number and add or subtract.

If that makes sense O.o

I'll put this post dead

Found out a better and easier way: 3 dimension array to split the 2 numbers so I can get rid of the comma,

Yes I am not a good programmer so it takes some time.

Thanks again
