Millisecond Forums

Hi!

I want to run a study to measure orientation sensitivity, and I'm currently trying to trig the staircase demo to make this study.
The demo used color as a feature and update the color information like the below:

<shape target>

/ shape = triangle

/ color = (0, 135, 10)

/ size = (30%*2/4, 30%)

/ position = (70%, 50%)

/ rotation = 0

</shape>

...

<trial staircase_down>

/ontrialbegin = [

    values.staircase = 1;

    if (values.direction_down == 1) {

        values.targetvalue_down -= values.change_down;

    } else {

        values.targetvalue_down += values.change_down;

    };

    shape.target.colorred = values.targetvalue_down;

]

But when I changed it to the rotation like the below;

shape.target.rotation = values.targetvalue_down;

The rotation of the shape doesn't change even though the targetvalue_down value itself is changing every trial.
I tried a similar twig using the width, then it is working fine - width changes accordingly every trial. Any ideas on what is happening here?
I can also post the entire script if it is helpful.

Thank you!
