 Posted: Sun Sep 21, 2008 5:39 am Post subject: trouble with variables containing another variable |
 |
|
So I'm pretty new to scripting of any kind. I've done a bit, but this is my first major undertaking. I'm working on a script to do some cool music stuff w/the midi output library i found on this forum.
Anyway, the trouble is this in this snippet of code:
| Code: | Octave = 3 ; starting octave is 3 (middle C)
Base = (Octave*12+set) ; our base note is our octave times 12-- so at start, from octave 3, it is 36-- middle C.
TTon = 0 ; third tonality modifier. -1=minor, 0 = major, +1 = augmented
STon = 0 ; seventh tonality modifier. -1 = dim, 0 = dominant, 1 = major
FTon = 0 ; zero = normal, -1 = diminished
Set = 0 ; 0 for set 1, 4 for set 2, 8 for set 3.
;here come the roots
r1 = Base
r2 = (r1+7)
r3 = (r2+7)
r4 = (r3+7)
;now the thirds
t1 = (r1+4+Ton)
t2 = (r2+4+Ton)
t3 = (r3+4+Ton)
t4 = (r4+4+Ton)
;fifths
f1 = (r1+7+Fton)
f2 = (r2+7+Fton)
f3 = (r3+7+Fton)
f4 = (r4+7+Fton)
;sevenths
s1 = (r1+7+3+Ston)
s2 = (r2+7+3+Ston)
s3 = (r3+7+3+Ston)
s4 = (r4+7+3+Ston) |
When I set r1 to an actual number directly, like 36 (which is what it should equal by default, or at least thats what I want it to do), then the function later on in the script that is set up to use that variable works properly. However when I set R1 to equal Base, it no longer works, even though, as i understand it, the math I've put in should be giving it 36.
I'm thinking this might have something to do with the %variable% thing, dynamic variables or whatever they are? Not really sure, though. Again, total neophyte. I'll appreciate any input you guys have.
Also, are variables case sensitive?
Thanks a lot, all.

Solution: Replace all = with :=

No! Not at all..

There were a couple of logical errors, here it is fixed and tested:
| Code: | #Persistent
Ton := 0 ; <= You need to initialise this
Set := 0 ; 0 for set 1, 4 for set 2, 8 for set 3. Relocated
Octave := 3 ; starting octave is 3 (middle C)
Base := (Octave*12+set) ; our base note is our octave times 12-- so at start, from octave 3, it is 36-- middle C.
TTon := 0 ; third tonality modifier. -1=minor, 0 = major, +1 = augmented
STon := 0 ; seventh tonality modifier. -1 = dim, 0 = dominant, 1 = major
FTon := 0 ; zero = normal, -1 = diminished
; Set := 0 ; 0 for set 1, 4 for set 2, 8 for set 3.
;here come the roots
r1 := Base
r2 := (r1+7)
r3 := (r2+7)
r4 := (r3+7)
;now the thirds
t1 := (r1+4+Ton)
t2 := (r2+4+Ton)
t3 := (r3+4+Ton)
t4 := (r4+4+Ton)
;fifths
f1 := (r1+7+Fton)
f2 := (r2+7+Fton)
f3 := (r3+7+Fton)
f4 := (r4+7+Fton)
;sevenths
s1 := (r1+7+3+Ston)
s2 := (r2+7+3+Ston)
s3 := (r3+7+3+Ston)
s4 := (r4+7+3+Ston)

Oh ok awesome I will try that out. What does initialize mean in this context?
Oh wait, I get it. Yeah, that was actually a mistake-- I renamed the variable to TTon but forgot to change it in the script.

Alright, so another problem now.
| Code: | Velocity := 100
CheckVel:
GetKeyState, Y, Joyy ; check left stick Y
GetKeyState, X, Joyx ; check left stick X
if Y > 55 ; if the left stick is down
{
Velocity:= -1(50 - Y * 2.54)
}
else if Y < 45 ; if the left stick is up
{
Velocity:= (50 - Y * 2.54)
}
return |
So I am pretty sure I am not explaining the math to the computer the right way up there because A) it doesn't work and B) the variables its outputting don't match up with what it should be in my head.
Basically I want to generate a number from 1-127 based on how far Y is from 50 (so 100 would equal 127 and 1 would also equal approx 127). I figure I'd need basically one equation, Velocity:= (50 - Y * 2.54). Except when I go above 50, it becomes negative and I need the output positive-- no big deal, just do Velocity:= -1(50 - Y * 2.54) when Y goes above 50.
Anyway, so thats what I WANT to do and I think the math I've got works on paper, I am just not scripting it properly.
Go ahead though, lets hear it, show me how its done!

Something like this??
| Code: | loop,100 {
msgbox % a_index > 50 ? ((a_index - 50) * 2.54) : ((50 - a_index) * 2.54)
} |
