## Follower Flags
These are required to tell the game what behavior you want the NPC follower to have. They are defined in [include/constants/follower_npc.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/upcoming/include/constants/follower_npc.h). The second list of flags is the same as the first, but with shortened names to make them easier to type when scripting. The first 7 flags in the list are individual behaviors, whereas the remaining three are bundles of flags. For example, if you use `FNPC_SURF` in `setfollowernpc`, the NPC follower will be able to Surf behind the player. If you use `FNPC_ALL_WATER` instead, the NPC follower will be able to Dive and go up Waterfalls in addition to being able to Surf. Feel free to add your own custom bundles of flags to the file to meet your needs.
If the NPC doesn't have unique running frames, you should not use the `FOLLOWER_NPC_FLAG_HAS_RUNNING_FRAMES`(`FNPC_RUNNING`) flag for them, as this will cause visual glitching. If the flag is not used, the follower will simply use their regular walking animation frames, just sped up. The only objects currently in the game that have unique running frames are the player and rival characters, so the running frames flag should be used for those.
To make sure the NPC follower uses the correct animation frames, you should add an entry to `gFollowerAlternateSprites` in [include/follower_npc_alternate_sprites.h](https://github.com/rh-hideout/pokeemerald-expansion/blob/upcoming/include/follower_npc_alternate_sprites.h). Only do this if your object has distinct animation frames for different behaviors (running, biking, surfing, etc). Follow the templates for Rival May and Rival Brendan that already exist there.
