The G. said: Through further checking, I only get the error upon changing things under the "Users Customization Options" section, specifically the behavior section. Any time I try to select anything but "Warn Player & Stop at Wall" it gives me a error reading: "SyntaxError: Unexpected identifier". This was caused by a typo on line 66 ("behaviors" was misspelled), but that should have been fixed a year ago with a commit from julianduque. The only thing I can think of is that Julian didn't increment the version number, so the one-click install is still serving an unchanged v2.2 of the script. The Aaron said: It might only be looking at paths on the DL layer. Might have to modify the script to look at GM layer paths. The script is meant to be configurable to look at lines on any specific layer, or all layers combined. As I said, this script was written before DL walls were capable of blocking movement, so the initial intent was to allow DL walls to pull double duty. However, I realized not everyone might want that, and not everyone able to do so uses DL, so I made the script usable with walls on any layer, if you so chose. Now that DL walls can block movement, the script is actually more useful with walls not on the DL layer. The G. said: I've done that with the script from github. I edited the settings to be exactly what I need and it doesn't seem to do anything. The biggest issue with it is there seems to be no indicator that the script is even running, so I don't know if it's some error stopping it or I'm doing something else wrong in the editor. What color paths are you using? The script will only look at walls of a specific color (#FF00FF by default, but that's configurable). Any paths of other colors will be ignored by the script.
