Scripting a Camera System

86

I used a pitch of -80 degrees to have the camera point down at the pawn. You'll notice

that my pitch says -14000 here though. That's because of UDK's rotation system that

I mentioned earlier which is based on radians, remember? A pitch of -80 degrees is

roughly equivalent to 14000 of Unreal's unit of measurement.

/** Hardcoded vector & rotator values for our camera */

defaultproperties

{

CamOffset=(x=-700,y=0,z=0)

CamOffsetRotation=(Pitch=-14000)

}

7. Next up, we need to make a change to our TutorialPawn class. There is only one
   small change here from the changes we made during our side-scroller tutorial. We're
   going to override the GetBaseAimRotation function found in the Pawn.uc class
   again to have it suit our needs. Add the following code:
   /*****
   USED FOR TOP DOWN Camera
   
   
   • Forces the weapon to use the pawn's direction for aiming,
     and not the camera's.
   
   
   • shots will be fired in the direction the gun is pointed.
     Used by PlayerController.
   
   
   • Comment this out if you are not using the Side Scrolling
     Camera.
   
   
   • @return POVRot.
     *****/
     simulated singular event Rotator GetBaseAimRotation()
     {
     local rotator POVRot, tempRot;
   
   
   
   

tempRot = Rotation;

SetRotation(tempRot);

POVRot = Rotation;

/** Stops the player from being able to adjust the pitch

of the shot, forcing the camera to always point down

towards the pawn

* We can still rotate left and right, however.*/

POVRot.Pitch = 0;

returnPOVRot;

}

As you can see, we've set our POVRot to use the rotation of our pawn. Therefore, our

camera's rotation will follow the pawn's rotation. Additionally, we've set our Pitch to

0 , so that the player no longer has any control over the pitch of either the pawn, and

by extension, the camera.
