Small Step Iterations for Large Param Change

[wimann]

Okay,

this is probably something quite easy and I'm just not thinking of the solution.

I want to change an angle by 5 deg steps until it reaches the full change.

In other words, if my desired angle is 90, then I want it to understand something like:

If currentangle > desiredangle then

currentangle = currentangle - 5

else if currentangle < desiredangle then

currentangle = currentangle + 5

else if currentangle = desiredangle then

end if

And I want for it to repeat until currentangle = desiredangle.

What am I missing?

Looking forward to gaining a better understanding iLogic and VB.

Will, have a look at this site :http://inventbetter.blogspot.nl/2011/12/using-while-loop-to-backsolve.html there is a good example. One sidenote, i think it's a good idea to add a counter to the While loop with the option to quit the loop. This can prevent that the loop will never end.

You may consider at least these 4 options:

Dim Angle As DoubleForEquals

'Debug.Print(vbNewLine & "Method 1")
For Angle = 0 To 90 Step 5
    'do something
'    Debug.Print(CStr(Angle))
Next

'Debug.Print(vbNewLine & "Method 2")
For Angle = 90 To 0 Step -5
    'do something
'    Debug.Print(CStr(Angle))
Next

'Debug.Print(vbNewLine & "Method 3")
Angle = 0 ' start value
While Angle <= 90
    'do something
'    Debug.Print(CStr(Angle))
    Angle = Angle + 5
End While

'Debug.Print(vbNewLine & "Method 4")
Angle = 90 ' start value
While Angle >= 0
    'do something
'    Debug.Print(CStr(Angle))
    Angle = Angle - 5
End While

Be careful when compare if X is equal to Y.
