DoHitTest & Multiple SlideStates

[Susan G. Campbell]

Hi Dina,

I'll take a wild guess here, based on your code sample and answers.  I
think David probably solved the SlideState problem, and this is
something else. I'm a little rusty at debugging other people's E-Basic,
so I may be way off.  From this code snippet:

	Select Case strHit

	Case "UpperLeft"
		c.setattrib "CorrectAnswer", 1
	Case "UpperRight"
		c.setattrib "CorrectAnswer", 2
	Case "BottomLeft"
		c.setattrib "CorrectAnswer", 3
	Case "BottomRight"
		c.setattrib "CorrectAnswer", 4
	Case Else
		Goto Label3

	End Select

It looks like what you're setting based on what the participant hits
isn't Motor.RESP but CorrectAnswer -- so it's changing the correct
answer based on what the participant answers, and not setting Motor.RESP
to anything (so it'll always be 1, corresponding to the left mouse
button as Ben said).  

Then in your comparison, you're comparing strHit (which is, I'm guessing
based on your case statement above, a string with content like
"UpperLeft") to CorrectAnswer (which is a number).  That's always going
to be false.  I'm not sure why CorrectAnswer isn't the name of the
object they should click on, but that's what this comparison assumes is
going on:

If strHit = c.GetAttrib ("CorrectAnswer") Then
		Motor.ACC = 1
	Else
		Motor.ACC = 0
	End If

You should be able to verify the content of these variables with the
judicious use of Debug.Print, though.  

Hope this helps,
Susan

Hi David,

Thanks for your suggestion!
I tried it out and the programme does run, but still does not log the
responses appropriately.
I acted like the perfect participant and made no errors.

This is what the output says:

Trial 1

CorrectAnswer: 1
StateName: UL
Motor.ACC: 0
Motor.RESP: 1

Trial 2

CorrectAnswer: 3
StateName: BL
Motor.ACC: 0
Motor.RESP: 1

Trial 3

CorrectAnswer: 2
StateName: UR
Motor.ACC: 0
Motor.RESP: 1

What I also noticed is that Motor.ACC = 0, even for the first trial.
I'm not sure how this can be solved.
