- Doing a rear animation and facing a direction:
When it comes to a rear animation, it’s the opposite. So if the character’s back is facing the reader and they’re facing towards the left, the rear animation and right direction is used. If their back is facing the reader and they’re facing the right, a rear animation with the left direction is used.
Here’s an example:
@JEMU776 stands screen center
@JEMU776 faces left AND JEMU776 is rear
This translates into:
Another example:
@JEMU776 stands screen center
@JEMU776 faces right AND JEMU776 is rear
This translates into:
As you can see she’s facing the opposite direction no matter what position she stands in. Remember to keep this in mind 
- And now to move onto walking rear!
Example A written again
EXT. CAMPUS QUAD LIGHTS OFF - NIGHT
@zoom on 320 366 to 270% in 0
@JEM spot 1.280 270 0 AND JEM faces left AND JEM starts idle
NARRATOR
Example: This lazy writer will walk to a rear spot LOL.
In this Jem’s standing at screen right and she’s facing left. She then walks to the the upper left side of the screen using a walking rear animation, facing left.
&zoom on 6 499 to 270% in 1.5
@JEM walks to spot 1.05 70 200 in 1.5 AND JEM faces right AND JEM does it while walk_rear THEN JEM faces left AND JEM starts idle
@pause for 1.7
NARR
End of scene.
Example B written again
EXT. CAMPUS QUAD LIGHTS OFF - NIGHT
@zoom on 0 366 to 270% in 0
@JEM spot 1.280 50 0 AND JEM faces right AND JEM starts idle
NARRATOR
Example: This lazy writer will walk to a rear spot LOL.
In this Jem’s standing at screen left and she’s facing right. She then walks to the the upper right side of the screen using a walking rear animation, facing right.
&zoom on 302 499 to 270% in 1.5
@JEM walks to spot 1.05 250 200 in 1.5 AND JEM faces left AND JEM does it while walk_rear THEN JEM faces right AND JEM starts idle
@pause for 1.7

End of scene.
Explaining Examples A & B
Explaining Example A:
First of all, Jem’s standing at screen right (spot 1.280 270 0 is the spot direction for screen right) and she’s facing left. Then I make her walk to the upper left of the screen using a walking rear animation, facing left (since rear animations are opposite, I’d write right, but she’d go left) and once she arrives at the desired position, I make her face left since that’s where I was making her walk to (to upscreen left using rear, facing left but in the script, it’s written right when she’s walking there since rear is always opposite but non rear animations aren’t so that’s good because we’d all throw a fit XD). I added the zoom there as a bonus (totally optional). I put & in front of the zoom so it happens at the same time the camera follows her and it occurs in 1.5 seconds, which is the same amount of time she takes walking to her new position. At the beginning when I placed the camera on her the % was 270. I kept that the same. The other values for the zoom changed in example A (320 to 6 means the camera went from right to left, the number decreased) and (366 to 499 means the camera went from the bottom to top, the number increased) so hope this makes sense ^^
Explaining Example B:
First of all, Jem’s standing at screen left (spot 1.280 50 0 is the spot direction for screen left) and she’s facing right. Then I make her walk to the upper right of the screen using a walking rear animation, facing right (since rear animations are opposite, I’d write left, but she’d go right) and once she arrives at the desired position, I make her face right since that’s where I was making her walk to (to upscreen right using rear, facing right but in the script, it’s written left when she’s walking there since rear is always opposite but non rear animations aren’t so that’s good because we’d all throw a fit XD). I added the zoom there as a bonus (totally optional). I put & in front of the zoom so it happens at the same time the camera follows her and it occurs in 1.5 seconds, which is the same amount of time she takes walking to her new position. At the beginning when I placed the camera on her the % was 270. I kept that the same. The other values for the zoom changed in example B (0 to 302 means the camera went from left to right, the number increased) and (366 to 499 means the camera went from the bottom to top, the number increased) so hope this makes sense ^^
Anyways, another thing! Both of these examples may be similar, so if you noticed patterns that’s awesome (ex. one of the things they have in common is in Example A, Jem walks from spot 1.280 270 0 to spot 1.05 70 200, there’s a difference of 200 between them (the bolded middle numbers, 270-70=200). In Example B, Jem walks from spot 1.280 50 0 to spot 1.05 250 200, again, there’s a difference of 200 between them (the bolded middle numbers, 250-50=200) and all other values follow a pattern, as you can see. BTW I just added this part because it seemed cool 
So yeah, try to look for patterns and I hope this helped, I tried to simplify it as much as I could, much love from a chocolate loving lunatic : )
Thank you for checking this out!

See you later XOXO 
thanks for this, Jem!
