# creature\_formations
[<-Back-to:World](database-world.md)
**The \`creature\_formations\` table**
This table allows to group mobs. Members of group will follow others, and attack their targets.
**Structure**
| Field | Type | Attributes | Key | Null | Default | Extra | Comment |
| --------------- | ----- | ---------- | --- | ---- | ------- | ----- | ------- |
| [leaderGUID][1] | INT | UNSIGNED | | NO | NULL | | |
| [memberGUID][2] | INT | UNSIGNED | PRI | NO | NULL | | |
| [dist][3] | FLOAT | UNSIGNED | | NO | NULL | | |
| [angle][4] | FLOAT | UNSIGNED | | NO | NULL | | |
| [groupAI][5] | INT | UNSIGNED | | NO | NULL | | |
| [point_1][6] | INT | UNSIGNED | | NO | 0 | | |
| [point_2][7] | INT | UNSIGNED | | NO | 0 | | |
[1]: #leaderguid
[2]: #memberguid
[3]: #dist
[4]: #angle
[5]: #groupai
[6]: #point_1
[7]: #point_2
## leaderGUID
GUID of group leader
## memberGUID
GUID of group member. NOTE: Is required to have an entry with `leaderGUID` and `memberGUID` with the `leaderGUID` in order to make the group work.
Example:
* Leader = 1
* Members = 2 and 3
| leaderGUID | memberGUID |
| ---------- | ---------- |
| 1 | 1 |
| 1 | 2 |
| 1 | 3 |
## dist
Maximum distance between group leader and member
Value must be >=0. If the value does not meet the condition the SQL will fail on `creature_formations_chk_1`.
## angle
Angle between leader and member
Note: Only degrees are used! Values should be between 0 and 360
Value must be >=0. If the value does not meet the condition the SQL will fail on `creature_formations_chk_1`.
## groupAI
Sets group member behaviors, values are:
| Value | Flag | Name | Comment |
| ----- | ----- | ------------------------------------------ | -------------------------------------------------------------- |
| 0 | | | No one assists no one and member doesn't follow the leader |
| 1 | 0x001 | GROUP_AI_FLAG_MEMBER_ASSIST_LEADER | The member aggroes if the leader aggroes |
| 2 | 0x002 | GROUP_AI_FLAG_LEADER_ASSIST_MEMBER | The leader aggroes if the member aggroes |
| 3 | | | Everyone assists everyone and member doesn't follow the leader |
| 4 | 0x004 | GROUP_AI_FLAG_EVADE_TOGETHER | Everyone evades if any member evades (enters evade mode) |
| 8 | 0x008 | GROUP_AI_FLAG_RESPAWN_ON_EVADE | Everyone respawns if members evade (enters evade mode) |
| 16 | 0x010 | GROUP_AI_FLAG_DONT_RESPAWN_LEADER_ON_EVADE | Used with flag 0x008 to prevent leader from respawning |
| 24 | | | Everyone but leader respawns if members evade |
| 512 | 0x200 | GROUP_AI_FLAG_FOLLOW_LEADER | Noone assists noone and member follow the leader |
| 515 | | | Everyone assists everyone and member follow the leader |
## point\_1
## point\_2
These values are used to set leaderGUID pre ending path points for memberGUID's where the path is a straight return path and memberGUID's should not crossover to other side of leaderGUID on direction change.
If your leader has a path like the one below where he moves to point 5 then back to 1 you would set point\_1 = 4 and point\_2 = 8 on the memberGUID. If the memberGUID is at angle 90 up to point 5 it will switch to angle 270 for the return trip. This is only needed to keep creatures on the correct side. these values can be left at 0 for creatures following directly behind leaderGUID or any creatures in a circular path.
