When translated into simple JavaScript, your trigger action would resemble something like this:
In the provided code, if isTrue is true, the else statement will never execute. It will only execute the if block.
If you set isTrue to false within the if statement, it will alter the value of isTrue before the else block is reached. Here's how it would look:
Even in this case, when the button is clicked for the first time, it will set isTrue to false and then perform "action A". Subsequent clicks will execute "action B" because isTrue will be false.
Your code didn't work because the interaction relies on a click event; nothing will occur until you click, and more important the "Reached_top" variable maintains the value of true after the initial button click. Therefore, you should implement a trigger to toggle the "Reached_top" variable.
Triggers in the final version will resemble the JavaScript below. The handleClick function toggles the value of isTrue using the ! operator, which negates its current value. Then, based on the new value of isTrue, it performs either "action A" or "action B".
I'm not very skilled at explanations, but I hope this sheds some light on your inquiry.
