Why specify the InputMask in the script when using goto after TextDisplay.run to terminate TextDispl

[Paul Groot]

Hi Jakob,

I'm not 100% sure about this, but my guess is that E-Studio generates code
where the inputmask of an object is initialized just before running
the object (you can check this in the full-script tab). And, since you run
the object explicitly in your own script in the try-again scenario, you
also have to initialize the inputmask explicitly yourself because the
generated initialization code is not yet called when you execute the
run-statement.

There are several workarounds for this. I will only explain a scenario that
doesn't use a goto-label, because goto's often have negative side effects.
My advise would be to put the practice block procedure in another  block
list that repeats several times (PracMasterList::Exit List = 999). Then,
instead of using a goto-label construct, simply call the terminate method
in case the ready-criteria are met (PracMasterList.Terminate)

If PracticeACC.Mean >= .80 Then
   EndPrac.Text = "Well done"
   PracMasterList.Terminate
else
   EndPrac.Text = "Try again"
end if

You might have to tweak other objects, such as the practice introduction
screen, to complete it: If the instruction should not repeat, then you can
simply place it before the practice master list. If the practice
instructions should repeat with different content, you could make use of a
Slide object having different tab's (SlideStates) with specific
instructions for the first and repeating runs. The Slide's ActiveState
property can be used to select the visible tab. The attached example shows
how you can do this. Sounds complicated, but is rather straightfoward
without additional inline script. *(In words: Define an attribute for
the active state in PracMasterList. Use the []-syntax to specify the name
of this attribute in the ActiveState property of the Slide. Set the list
ordering to sequential and include as many rows as required. Configure the
required active state for each row. Exit list should be reset to 1 cycle in
this case because the number of 'trials' determine how many times the
practice block.)*

Cheers,
Paul
