no. it's a platformer+ error. no other plugins are used in this project.
Viewing post in GBStudio Platformer Plus comments
its not a script:
steps to reproduce:
1) add platformer+ to project files
2) try to export
EDIT: it does not export if you try to use any of the events. It will export if you dont use the included events, but platformer mode is still unusable due to it deleting pretty important things like gravity and movement speed from the project files
As I've mentioned, this is not an issue that other users are seeing, which means that it's the result of some combination of issues on your end.
Have you tried adding P+ to a blank project? If that gives you an error, then it might that you've put the plugin in the wrong part of your project directory.
If it works in a blank project but not in your main project, then it could be any number of issues. In a very large project it could be that there isn't enough room in a bank to add the plugin; or if you've done any engine edits then those can create conflicts.
Without a more detailed description of your setup, it's impossible to troubleshoot.
