Post that in a new thread please. :)

I have split your post into its own thread. Please do not ask for help with specific scripts in an unrelated topic. If it's a script that has its own topic here (in RGSS3 Scripts), you can post your question in the thread for the script. Otherwise, just start a new thread in RGSSx Script Support and ask your question - making sure you include a link to the script.


I cannot access dropbox from my work pc, so I can't follow those links. If you haven't included a link to your script, please edit your post to add one. Thank you.
