Hey guys whats up?
Im trying to figure something out,
Whenever i do my coding etc and i want to set a dynamic mc, i use the old school coding like this…
setProperty(“myMc” add i,\_x, 2);
right, well whats the coding stlye in mx? I havent figured that out. i would want to do something like
\_root.(“myMc” add i).\_x = 2;
But im not sure whats proper, any ideas?

alrighty =) well i tried that, no worky…
check out my code…
this works…:
setProperty(“fx” add i,\_x, startx + Number(i\*kern));
setProperty(“fx” add i,\_visible, true);
this doesnt… hmm… any thoughts?
\_root[“fx” + i].\_x = startx + Number(i\*kern);
\_root[“fx” + i].\_visible = true;
ps. and i do have the path correct =)

I had the same problem. What I did was to evaluate the expression first and then assign that variable to the \_x property
abcd=startx + i\*kern;
\_root[“fx” + i].\_x = abcd;
Try this! Hope this helps!

was that trace action right underneath your setProperty code?
put it there and see what it traces.
