How to add Death Cam in SOD?

So I'm about to release Halloween Candy Pack 2024 (Several One Level Mini Games)
One the Games is an Assassination Mission, I got a cross hair added, but I thought it would fitting to add the Death Cam to, and of course I mostly mod for Spear Of Destiny(/sdm4sdl) (a few are Wolf3d in the Candy Pack though),
 I tried pasting the Death Cam stuff outside of the ifndef spear parts, and adding it the particular Boss, but I get this 

WL_ACT2.CPP|4142|error: 'CheckPosition' was not declared in this scope|

  } while (!CheckPosition (player));

and 

WL_ACT2.CPP|4160|error: 's_trasnsdeathcam' was not declared in this scope|

           case transobj:     // Assassin
            NewState (ob,&s_trasnsdeathcam);
            break;
#ifndef SPEAR

for errors.


I have some time tomorrow, to get this working, I may drop the other 5 Games, tonight and make an update. 
About to play through them.....

Any Help would be much obliged Thank You 

Are you checking Diehard Wolfers?:
https://dhw.wolfenstein3d.com/viewtopic.php?p=103308&hilit=DeathCam+in+Spear#p103308

I checked there, I didn't find anything, though I also didn't find that, although that doesn't really touch on the issues I'm having. 
Thanks though

This is the closest thing I could find.  It's about how to DISABLE, but not ENABLE, the Deathcam: http://www.wolfenstein3d.co.uk/coding-deathcam.htm
