reading / writing pointattr

[Follyx]

2 Wrangles:

1.

setpointattrib(0, "pointatr", 2, 11);

@getatr = @pointatr;

2.

@getatr = @pointatr;

so why istnt the @getatr not affected (spreadsheet is still 0)?

Only if I put the @getatr=@pointatr in a following wranglenode its working. Whats the background for that?

Wranglenodes work of all points in parallel. But also the included instructions? Not first the setpointattrib for all points and then the a=b?

because houdini writes the value on the geometry after the code is executed, so while you are in the code, you cant' read @pointatr because its value has not been written to the geometry yet.
