Just to give everybody a heads up in case you want to copy some event sheet code between different projects, it might not show a warning message, BUT trust me, DON'T DO IT.
If you attempt to copy over an event sheet that contains references to objects which don't exist in the current project, Construct will warn you about that. When that happened, I tried to create the objects which were referenced and give them the same names, and then copy over the event sheet. At that point, Construct didn't throw any warnings or errors, everything looked just fine, the entire sheet copied over, and it looked like I was going to be saving some serious time, since I've got a lot of projects where certain event sheets (which I essentially use as containers for each respective sprite's logic) were nearly identical.
Fast forward to almost two hours later, where some of my scripts just weren't executing properly, and I finally narrowed it down some pick events were not matching known UID values, meaning that even though they appeared to be doing a pick on the same object as the last project with the same name, they obviously contained some address references that were different. Both the Pick operation code and the Create Object code was stuff I had copied from the aforementioned project's event sheet.
After re-creating the aforementioned picking and associated create object commands from scratch, the code worked. Anyways, this is just a heads-up to anyone thinking of trying to open up multiple projects in the project tab and trying to copy over event code. As it stands now, unless you really ENJOY putting tons and tons of Append Text statements in your code, I wouldn't recommend trying it.
