It would be great if we could specify to the engine which external program we want to use as a script editor and then be able to automatically launch that editor with the script that I've selected to edit. If the script doesn't exist yet then it could create a template script file by the specified name and launch the editor.



So, in practice, you would be in the entity properties and enter a script name such as mymain.lua. The engine would see the file doesn't exist and create a template version with the correct main function name and empty function. Then it would launch your script editor with the file loaded. After you save your script and apply changes, the engine would load up the script for use.



This saves a lot of time in development and is more like what we see with other engines. I still think you should also be able to just select an existing file as well.

I agree with this.
