After BlueprintReadOnly lecture, Unreal crashes: Using 4.18.3

Unreal Courses Talk

#1

After this lecture, Unreal crashes on play. I am a brand new coder. Appreciate any help. This is what I have tried:

  1. Removing the BP for Move Forward
  2. Commenting out the UE_LOG
  3. Commenting out the BlueprintReadOnly line
  4. Tried playing from Main menu. It did not crash until I hit the start button

I should say that my code compiles without a problem. As far as I can see, it is identical to Ben’s. Here is the error message I am getting:

I’m getting the exact same result with the same Unreal version.

#3

Thanks to a post from an earlier video, I realized that sometimes, when things are added to the Tank_BP, it resets the Projectile to none. By resetting it to Projectile_BP, the problem is solved.

#4

I saw that earlier post, but I completely forgot about it. Thanks!
