I did a search and saw a topic from 3 years ago asking this same question. I love Construct, but I really need to be able to do as much with JS as possible so that I can quickly reuse bits of code that are common across games.
One example is simply pausing the game and having a menu pop-up. Every game has this and I'd love to build a script that I can just import to enable this functionality.
From my research though it doesn't seem to be in the scripting docs.
Any particular reason for omitting this functionality? Or is it there and I am just not understanding how to do something like set the timescale = 0 at the system level via scripts?
