I too am having issues with the script. It does move around but does not battle. I have a Oneplus 7 Pro with resolution of 1440 x 3120. Here's a screen shot: ibb.co/WgTpd8P
Hello! I know this is a late reply, but I'm hoping I can help ppl with similar issues.
PLEASE NOTE: I am not well versed in lua script writing and I have used logical deductions to resolve the issue formyself. You may choose to follow what I have done, but you must take responsibility for any breaking of the script.
I was having the same problem so I opened up the script in a lua editor on my phone. From here I pieced together some of the settings I found in snap and play with the "Another Eden" lua file. Basically what I think I did was add edited compare settings from snap and play to this file. Below is what I now have for my "settings" section of the lua script:
For this line "Settings:setCompareDimension(true, 1480)" There is probably a way to get the correct dimension automatically but I don't know it so I put my dimension in manually. You can find your resolution in your phone display settings.
