Hello. I downloaded the graphics of the arrows in the pictures folder, then I painted the arrows in another color and made them transparent with RPG Maker XP with materials - import - transparent and I chose white and now its transparent.
Then I paste the script that I'd copy from the Essentials Wiki and paste them above main, called it ExitArrow
and made an exit-event called ExitArrow
My apologies. I seem to have included a couple of constants from my own project when I posted that tutorial. I've edited the page to remove those constants and put in simple numbers which mean the same thing. Go recopy the script into your project and test it again. Again, sorry about that. ^_^;
