@anmhuicin @Matty @matt Had a quick go at getting live config updating working in Unreal. This video shows controlling the player walk & jump from a spreadsheet in Celbridge, while the game is running in Play-In-Editor mode.
The Python script also does some simple validation, so you get an error message if you enter a negative number for example. It took quite a bit of fiddling around with editor preferences, data tables, Blueprint structs and functions to get everything connected up properly. I think a Celbridge Connector plugin for Unreal that does all that automatically could be really useful.
