Changing sub-object duration property

[Michiel Spape]

Hi,
To my knowledge, duration is a property of a slide and its sub-objects (slide states being sub-objects themselves, in a way) cannot have independent duration, like all other properties shown on the duration tab. I grant you, it would be incredibly useful, if this were possible!
Apart from that, what you are asking can easily be implemented by using a copy of the same slide right after the other one, which is almost exactly the same thing I suggested in my previous post here. 
So, you have 
Slide1, duration until mouse, yes and no images, maxcount = 1
Slide2, duration of 2000 - Slide1.Duration (put an inline in between the slides), no images, maxcount = 100 (or something).

Would that work?
Best,
Mich

Subject: Changing sub-object duration property

Hi,

I'm not sure if I'm missing something...

I've created a slide object which contains a "Stimulus" image, a "Yes
Response" image and a "No Response" image. I'm using mouse input to
register the response and using HitTest to record and score the
location of the mouse response as either "Yes" or "No".

I would like to set the Stimulus image duration to 2000msec, allow any
mouse clicks to be recorded during that duration, and if no response
is recorded, leave the "Yes Response" and "No Response" images on the
screen until a response is recorded.

I have tried to change the duration of each sub-object separately, but
each time I change the duration it applies to the entire slide. I have
also tried using different slide states and multiple slides, but when
I do this the HitTest no longer records a single response (i.e.
participants need to respond twice).

Is it possible to change the individual properties of sub-objects on a
single slide?

Any help would be great!

Cheers
