问题
I want to display a sentence with words in different colors within the same frame . But all the code I've seen just change the color of the stimuli as a whole , not a part of it ... Here's my code for a try ,but it failed
#!/usr/bin/env python2
# -*- coding: utf-8 -*-
from psychopy import visual,core
win = visual.Window([400,400])
sent=[u'先生',u'を呼んだ',u'学生が',u'教室に',u'入った。']
sent[0].color=[1,1,1]
sent[1].color=[1.0,-1,-1]
sentence=visual.TextStim(win,text=sent[0]+sent[1])
sentence.setAutoDraw(True)
win.flip()
I am wondering whether there's a way for me to change the text color before it becomes a visual.TextStim ?
回答1:
No, the TextStim applies formatting (colour, italic, etc) to its entire contents. If you want words with different colours, they unfortunately each need to be in their own TextStim
An alternative is to the use TextBox class which I think allows per-character formatting, but only for monospace fonts:
http://www.psychopy.org/api/visual/textbox.html#psychopy.visual.TextBox
Having said that, I've found it doesn't work reliably at present, at least on Mac OS.
