[Maya-Python] attributeAffects and input output name?

[miarmy]

hi.

how can i know Which of input attributes run compute function of my
node???(in compute function )



example, i have:

attributeAffects(inputA, ouputB);

attributeAffects(inputB, ouputB);

attributeAffects(inputC, ouputB);

attributeAffects(inputD, ouputB);


Which of inputs(inputA or inputB or...) run compute function ???
..........
Excuse me,I don't speak English as well as you....

I can’t tell for sure, not without an example of sorts, but it looks like
you’ve got the answer in the question. attributeAffects is how you tell
Maya which attribute should trigger your compute function. What have you
tried so far, and what happens? What did you expect to have happen?

The compute function won't be run until you ask Maya for outputB, right?
Changing the inputs just flags the output as dirty, and then accessing the
output causes the calculation to be done.
