Guy i need Help, I’m used to do thing with bp, but I decided to try to learn c ++ so I started with the basics in ue4 that was to make a character walk, so i search on google and find this tutorial A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums, I made it to the moving part, where it started to go wrong, i stater have problems with c2027, c2227 and another one with character.h even with out using, i will copy and paste the log and scripts

You are trying to access the Character Movement Component of type, UCharacterMovementComponent but it’s not included, which is why it complains about the undefined type.
God bless you, thanks for the help.
So it’s not my fault
Because in the tutorial did not say to add this command
Is this because it may be out of date?

OMG why is it so annoying to program
I’m stopped for 1 or 2 days, because I can not fix the code
I entered the site that you indicated to me, it worked a part, but now I have this error
