Hi, just wondering can I put the timer in the center of the screen, or anywhere to my liking? I’m making a timed dialogue choice. Thanks! It’s a very handy script! ;)
Unfortunately not without modifying the script. I currently don’t have time for requests but you could ask in an rpgmaker forum to see if someone will help :)
