My Number Counter Doesn't Work In Animate CC

Question

Hi,

I've written javascript to cause a number to count up or down when the plus button or minus button is pressed. The problem I'm having is that after I press the plus button and, the numbers start incrementing, if I then press the down button the number increments one more before it starts decrementing.

So if I count up to five, then press the minus button, the number goes to six before starting down again.

I couldn't get the fla to attach so I've attached a couple of screen caps to show my work.

Thanks

Hi. If used postfix, with operator after operand (for example, x++), the increment operator increments and returns the value before incrementing. If used prefix, with operator before operand (for example, ++x), the increment operator increments and returns the value after incrementing. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Increment So try this:var y = 0;function fl_MouseClickHandler_2(){this.NumCounter.text = ++y;}function fl_MouseClickHandler_3(){this.NumCounter.text = --y;}this.NumCounter.text = y;this.Btn1.addEventListener("click", fl_MouseClickHandler_2.bind(this));this.Btn2.addEventListener("click", fl_MouseClickHandler_3.bind(this)); I hope it helps.
