My Building Escape after protecting From A Null Pointer lecture

TP_MakeGames · June 29, 2021, 12:55pm

Hi There,

In this lecture, we protect ourselves against a null pointer(a null pointer is a pointer that points to nothing).

VS code-

I just added another check for 0.0 rotation as I just did something that made a door’s rotation 0, so yeah, just added it for sake of checking.

UE Editor-

OpenDoor component added to Sphere(Actor1)-

As you can see, 0.0 rotation and no pressure plate attached-

You’ll see 2 errors in the log.

Thanks for reading,
BYE!!

This is a very key lecture. Protecting your pointers is extremely important ion C++.

Indeed it is if don’t protect those pointers, UE will crash without giving any helpful error messages.
