Increase a variable in Dynamic Text field with JS

[Bobby Jourdan]

Hi there,

I got a button on the stage and a variable set to 0.

I would like to increase the value of the variable every time the user clicks on the button.

I try this code but not sure about the function...

//dtc_Hits is the instance name of the dynamic text field;

//inst_ButtonMovie is the instance name of the button to be clicked

var Hits = 0;

this.dtc_Hits.text = Hits

this.inst_ButtonMovie.on("click", function(increaseHits) {

Hits++;

})

PS. I know that the error is in the line Hits++ because I try an alert message and it works...

Yes, your Hits++ works, but you need to update the text field after you update the variable. So just add the line this.dtc_Hits.text = Hits; as the last line in your function.

Thanks so much. I knew it is a small thing ...

It works well, but the counter resets when the movie loops. it is about 4 seconds - 100 frames.

How could I make it so that the variable continues to be increased even after the movie loops?

Thanks again!

That’s because your loop goes through the frame where you set the variable’s initial value. So, if all of this code is on frame 1, just loop back to frame 2 and the variable won’t be reset to 0.

Thanks, that did the trick.

Now I need to dig deeper and set a score as an objective.
