how to use setexpression with user created variable?

setexpression() /getexpression() Is used when you need to set or get values dynamic, instead of static command

Value = 1This can only target ’Value’, you can of course mix it with IF rules for switching between setting different Values. 


But now we need dynamic set and get of values Inside an object:

setexpression(obj path, expression, value)
If you are using the script inside an obj or next to it, lets say a ’Fader’ and we want to change X 
Then command will look like this:

setexpression(Fader,'x', 1.0)

variable must be a string ’x’ , but because of that you can now combine text with lets say an counter in a "for loop"


decl list = ['x','y','z'];
decl a;

for(a=0;a<3;a++)
setexpression(Fader,list[a], 1.0);
or if your object is full of X0,X1,X2,X3,X4 variables 
Then you can do:

decl a;
decl Val;

for(a=0;a<5;a++)
{
Val = 'X' + a
setexpression(Fader,Val, 1.0);
}
to take this a step further, lets combine the setexpression with findobject() command

findobject() works by converting a string into an obj command like:
From 'Fader' to just Fader

lets say you want change x in 8 Faders, labeled: Fader0,Fader1,Fader2,Fader3 ect.


decl a;
decl Val;

for(a=0;a<8;a++)
{
obj = findobject( 'Fader' + a)
setexpression(obj,'x', 1.0);
}
if you have 64 faders, then just change a<8 to a<64

getexpression() works the same way. 

but this is how you would use those commands in scripting.

Just write if you got more questions and I will reply when I have time.
Just been busy last +3 months learning how to convert my lemur project into a real app and still are.
