Intellisense, Live Errors, and Squiggles
UE4 projects now have proper IntelliSense support, including a live Error List and squiggles.
(See below for how to enable it.)
IntelliSense recompiles C++ as you type. This is a lot more powerful than only VAX's syntax
checking, as it uses a full C++ compiler that verifies every line of code. It is awesome and it will
speed up your workflow!
Along with squiggles, you will also see IntelliSense errors in the Error List for any file you are looking at.
You can turn this on or off in the right-click menu in the Error List.
You may have already disabled Squiggles because they did not work with UE4 projects. Make sure to hit the
C/C++ Advanced tab and use settings similar to below.
When you open a C++ file, you can see the IntelliSense compiler "working" by looking for this icon:
