Hi,
I'm not familiar with Joiplay, and I don't have an Android device, so it'll be difficult to test on my end. "Unexpected end of JSON input" means there's a user input error. For example, if a weird character like "!" or "$#" is in one of the parameters or plugin command arguments, the code wouldn't be able to parse it. So that's one place I would start looking.
Here are some questions that might help zero in on the problem:
- Are you able to reproduce the issue on PC, or is it specifically a JoiPlay problem?
- How many players have encountered the error? Is it most players, a handful, or all of them?
- Does the error occur at the start of the game, when the player encounters a sensor, or on a specific sensor? Does it happen every time or just some of the time?
- Are you certain that the error is caused by the plugin, or could there be some other compatibility issue? Check the parameters of any other plugins that you're using to see if you accidentally typed a random character in the field.
Hope that helps,
