Fixed Order of Pictures

[Michiel Spape]

Hiya,
Long-winded? How long do you suppose any answer would be to this question :) No, seriously, if you have gone through the tutorial, and maybe even our little guide, you might understand that what you are asking is indeed a little tricky on a number of levels:
1. Four pictures, dumped in a slide, but: clicking on them (oomph). There's an example in the e-prime online help thing where they have this hit-test for mouse-clicking operations. I'm sure it's here somewhere in this mailinglist as well, certainly discussed a few times. Just make sure you save the response.
2. Four clicks, not one, is most easily achieved (I say), by having four slides (with four hit-tests); just make copies of them by control+dragging them. 
3. Four responses... If you have one attribute, say "CorrectResponse", and four responses to slides pic1 pic2 pic3 pic4, you could just do something like:
c.SetAttrib "Y_Resp", pic1.Resp & pic2.Resp & pic3.Resp & pic4.Resp. 
if c.GetAttrib ("Y_Resp") = c.GetAttrib ("CorrectResponse") then c.SetAttrib "Y_ACC", 1 else c.SetAttrib "Y_ACC", 0
4. But of course, you want more than that, compare each response individually. Of course, you could just have four correct responses and 4 responses, so I suppose you'd end up with four "Y_resp"s (Y_resp1...4) and four "CorrResps" (CorrResp1..4). 
5. Assuming you don't want to go for animations (in which case I'd suggest abandoning E-Prime altogether, because your whole thing is MUCH more easily achieved in Flash to begin with), you might do something like:
Dim I as integer
For I = 1 to 4
	If c.GetAttrib ("Y_Resp" & cstr(i)) = c.GetAttrib("CorrResp" & cstr(i)) then SoundWRONG.play else SoundRIGHT.play
Next I
... that is, assuming you have made two soundbuffers (SoundWrong and SoundRight), but this is pretty well documented in the ebasic help.

Best,
Mich

Subject: Fixed Order of Pictures

Hi there,

I'm new to E-Prime and finding it a little tricky. I'm wondering is it
possible to make a level whereby four pictures are presented and they
must be clicked on in a certain fixed order? So for example if the
fixed order is pic1, pic 2, pic3, pic 4 and the subject clicks pic
1,3,2,4 then for the clicks that were correct a certain sound and
animation will occur to let the person know and for the ones that were
wrong another sound and animation will occur. And then I'd like to be
able to compare what the subject clicked to what they were supposed to
click?

Sorry this is very long winded, any help would be much appreciated!
