 If you simply lowercase all the names in [data/pokemon/names.asm](../blob/master/data/pokemon/names.asm) and rebuild the ROM, the first letter of their names may be missing. The cause is changing `"FARFETCH'D"` to `"Farfetch'd"`, because `'d` is actually a single character. The fix is to pad its name to the same length as all the rest with an `@`, so that it becomes `"Farfetch'd@"`.
 
 
+## Pan in cutscenes by making the player invisible
+
+The player's object is always at the center of the screen. So if you want to pan the camera during a cutscene, you have to get around that. The key is the `show_person` and `hide_person` movement commands, which make an object visible or invisible.
+
+Let's say you have a map with two placeholder sprites: `YOURMAP_CHRIS_PLACEHOLDER`, an `object_event` which uses `SPRITE_CHRIS`, and `YOURMAP_KRIS_PLACEHOLDER`, which uses `SPRITE_KRIS`. Then define these movement scripts:
+
+```
+ShowPersonMovement:
+	show_person
+	step_end
+
+HidePersonMovement:
+	hide_person
+	step_end
+```
+
+In your cutscene script, to show the placeholder and make the player invisible:
+
+```
+	checkflag ENGINE_PLAYER_IS_FEMALE
+	iftrue .ShowGirlPlaceholder
+	appear YOURMAP_CHRIS_PLACEHOLDER
+	jump .HidePlayer
+.ShowGirlPlaceholder
+	appear YOURMAP_KRIS_PLACEHOLDER
+.HidePlayer
+	applymovement PLAYER, HidePersonMovement
+```
+
+And to make the player visible again and disappear the placeholder:
+
+```
+	applymovement PLAYER, ShowPersonMovement
+	checkflag ENGINE_PLAYER_IS_FEMALE
+	iftrue .HideGirlPlaceholder
+	disappear YOURMAP_CHRIS_PLACEHOLDER
+	jump .HidPlaceholder
+.HideGirlPlaceholder
+	disappear YOURMAP_KRIS_PLACEHOLDER
+.HidPlaceholder
+```
+
+In between those script snippets, you can move the player around to look like the camera is panning around the map.

 ## Prevent NPCs' heads from flipping when they walk down
 
 When NPCs walk up or down, they flip horizontally every other frame to create the alternating left-right step animation. But for NPCs with asymmetrical faces, this can look awkward when they walk down.
