Hello there.
I am really sorry for the ultra noob question:
I have a cube, that I would like to resize with a VEX function

float test = ch("../transform1/sz");

if(ch("../line1/dist") <= 2)
{
    @scale = set(1.0,3.0,4.0); //resize box. not working
    @sizey = 3.0; //size box. not working
    @Cd = set(0,1,0);//debug purpose. if green, code is compiling
    test = 3.0; //going through a transform node doesn.t work either...
}
else
{
    @Cd = set(1,0,0);//red. if red, code updates
}

I don't understand why I cannot resize my cube....
thank you for your help

matrix M = ident();
scale(M, chv('t'));
@P *= M;

thank you for your message!
here is what I am trying to achieve ;
I have a box, that I 'copytopoints' on a line
I try to instantiate the box on every point on the line, and the amount of points on line changes depending on its length...

The problem is when I make the length of the line change, in a float way (for example : 1.43), there is either a gab between boxes (if under n.5 float value : 1.3 for example), or an overlapping geometries (if over the n.5 float value : 1.6 for example).
like the picture here :

I thought it would be easier to play with vex, but maybe there is a much easier way to play it around.
what do you reckon?


I did it with VEX
I am not sure it works tho. I will come back to report after my tests

vector toscale = chv('t');
matrix M = ident();
if(ch("../line1/dist/")%1 <0.5)
{
    toscale.x = ch("../line1/dist")+ch("../line1/dist")%1;
    @tx = toscale.x;
    scale(M, toscale);
    @P *= M;
}
else if(ch("../line1/dist/")%1 >0.5)
{
    toscale.x = ch("../line1/dist")-ch("../line1/dist")%1;
    @tx = toscale.x;
    scale(M, toscale);
    @P *= M;
}
