viztask.waitkeydown
Hi guys,
I have some question in using viztask.waitKeyDown. I know it returns a viz.data object with the key value and time. But I do not know how to do 'if' judgments with the key value. Here are the codes: d = yield viztask.waitKeyDown(None) Key = d.key RT = d.time - startTime if Key == 'J': acc = 1 else: acc = 0 data = open('data.txt', 'a') trialData = "%s\t%s\n" %(acc,RT) data.write(trialData) I would like to know if the key pressed is 'J' or not. How should I write this line? And another question is, is there any way to clear all key pressed before I do the judgment? Many thanks!! |
Here is a simple example:
Code:
import viz |
