Ok, I will split this into two. One for my particular bug itself (I'll create a new post on bug-report), and this one for the debugging thing.
First of all I want to thank you for the extended post. Those values you tell me are set from the very beggining
But while they are useful for automatic messages from the engine, I can't do anything with them to debug values when I want.
I also saw the log window, but it's only for VisEdit.log. It's useful, but it will be even more useful if we could see also message.log in real time. I tried to use external commands as tail, or notepad++ with real-time monitoring, but they don't work with fine (maybe because of the way Visionaire opens the file).
And finally, I tried the console, but I'm not so sure I can send LUA commands. I tried to define a variable but I couldn't.
Indeed, what I was asking for was like the log window, but with the ability to send commands to the player. Maybe a mixture between the console and the log window.
