whats the target of print?

In oder to debug (read: in order to guess differences between expectations by documentation and real behaviour of implementation^^) i came across print, which prints to *where*?

I already found the console (documentation: "Nähere Informationen dazu finden Sie in einem separaten Kapitel." - ??), but where does my print print to?

for macOS:

Or if you are using VS5 then you can read the log in the developer console while running your game via the editor. Press TAB to open & close the developer console.

Also here's a quick tip: If you hover the mouse over the icons to the left of the search bar on the editor it will dropdown a menu. Click on the option that says "goto messages.log" to open up the folder containing the log files, save files & config.ini for your opened project.

well, does not seem to work.

I added a simple print("test") to a script I know that gets executed, but while the function does what it should do, the print goes to nirvana, there is no 'test' in the messages.log

I need some way to output values for debugging.

Open up the options for VS editor. Go to player & set log level to info.
