Variable Update

[lh555]

Hi Jeremy,

I am currently working on an experiment and I found that I needed to use a variable element to keep track of how many
trials the user had completed. I tried debugging and trying out the general behavior of the variable element. To do that,
I created the following experiment:

PennController.ResetPrefix(null);

Sequence('test')
newVar('counter',10).global();

newTrial('test',
    getVar('counter')._element.value == 10 ? [
        newButton('button','True!')
            .print()
            .wait()
        ]:
        [
        newButton('Button', 'False :(')
            .print()
            .wait()
        ]
      ,
    getVar('counter').set(v=>v+1)
)

newTrial('test',
    getVar('counter')._element.value == 11 ? [
        newButton('button','True!')
            .print()
            .wait()
        ]:
        [
        newButton('Button', 'False :(')
            .print()
            .wait()
        ]
)

When running this file, the statement getVar(‘counter’)._element.value == 11 evaluates to false. I don’t understand
why this is happening. I would appreciate it if you could help me out.

Thanks

Hello,

I have resolved the issue by simply using the var.test.is() syntax and a functional expression.
