Assigning multiple thresholds in multiTarget

Hello Jaewon,

I am making a task where I require one target and x number of distractors generated with new properties each trial, each of a different size within a range. I would like to be accurate with my touch thresholds but I cannot figure out a way to assign multiple thresholds using the multiTarget adapter..

A snippet of my code is attached.

To use different thresholds per target, put them in columnar order, like a n-by-1 or n-by-2 matrix. n is the number of targets.

mul = MultiTarget(touch_);
mul.Target = [-5 0; 0 0; 5 0];
mul.Threshold = [1; 2; 3];      % a column vector
mul.WaitTime = 5000;
mul.HoldTime = 500;
scene = create_scene(mul);
run_scene(scene);

Thank you Jaewon, that works well.

Forgive me if it is documented somewhere, but how would I only end the trial when the target is touched for hold time? I would like record when subjects touch distractors but I would not like the trial to end when they do so. Please let me know or just direct me, thank you in advance.

There are so many ways to detect such a behavior. You need to use a little imagination. For example, you can repeat the scene until the subject touches the target.
