Miguel Romo check again it's there File Name: Demo Example
Thank you for your help, Lordshiva1948. I'm checking your modified file, but it still having bugs. Is it that complicated to make it work? It seems to be harder than I thought...
Update:
It seems that I finally got it, although the characters change their positions when I touch the button to make them appear/disappear and that causes some "oddities" in the game...
And the problem with jumps persist. I've set an action when the player touches any area of the screen, but I don't want to activate this action when an UI button is touched. I only want to activate the button action. How could do this correctly? I thought Construct 2 respected the Z order when you touch or make click on the UI or another element of the screen.
If the characters jump when any region of the screen is touched (one tap), how could I do to assign a double tap to change between the characters without conflicts with the number of taps?
