I'm trying to access components (in this case verts) with an expresion and its not behaving as expeted. For example.
Adding the folowing code to a cube's atributes.
int $i;
for($i = 0; $i < 8; $i++)
{
float $tmp[] = `xform -q -ws -t ("pCube1.vtx[" +$i +"]")`;
print("test - " +$i +" - " +$tmp[0] +", "+$tmp[1] +", "+$tmp[2] +"\n");
}
Outputs what I would expect when I hit the creat/edit button in the expresion editor:-
test - 0 - -0.5, -0.5, 0.5
test - 1 - 0.5, -0.5, 0.5
test - 2 - -0.5, 0.5, 0.5
test - 3 - 0.5, 0.5, 0.5
test - 4 - -0.5, 0.5, -0.5
test - 5 - 0.5, 0.5, -0.5
test - 6 - -0.5, -0.5, -0.5
test - 7 - 0.5, -0.5, -0.5
so I know the code is valid, however upon chaging time on the timeline all I get is this:
// Error: An execution error occured in the expression expression1. //
// Error: line 5: No object matches name: pCube1.vtx[0] //
I've tryed writing mel procs to return the position of the verts but whilst they work running from within the script editor I get the same result running them from within the expresion.
If I replace ("pCube1.vtx[" +$i +"]" with pCube1 it works just fine! Are component level atributes not accesable when an expression is run with a time change?
Thanks
