# Role Queue
Setting up Role Queue is Simple. Once you have edited your Lobby Configuration with your preferred roles, adding your players to select their role is simple.
{% hint style="info" %}
You should still be keeping track of your player's roles internally so that you can figure out what you will be doing!
{% endhint %}
Simply have the key as string `role`
Once you have that, just input what role your player is queueing as and then you're set.
### Multi-Roles
In some games (like League of Legends, Overwatch) you can select multiple roles to find a game faster. This must be formatted as an array when being input to the system for it to take effect.
The system will take in players who have the least amount of roles as the highest priority to be matched AND the order matters. If a Player doesn't mind playing anything and has all selected roles they will be in the lowest priority and their roles will be read from left to right in an array.
Examples from the [Playflow Docs](https://docs.playflowcloud.com/unity/matchmaking#advanced-features):
```
// Player's preference array:
["support", "adc", "mid"]
// System tries:
// 1st: Can they be support? → If yes, assigned!
// 2nd: If not, can they be adc? → If yes, assigned!
// 3rd: If not, can they be mid? → If yes, assigned!
```
```
// Assignment priority (highest to lowest):
Player A: ["tank"] // 1 option - HIGHEST PRIORITY
Player B: ["tank", "healer"] // 2 options - medium priority
Player C: ["tank", "healer", "dps"] // 3 options - lowest priority
// Player A gets first choice, then B, then C
```
```
// Both want the same roles:
Player1: ["support", "adc"] // Joined lobby first
Player2: ["support", "adc"] // Joined lobby second
// Result:
Player1 → Gets "support" (first preference)
Player2 → Gets "adc" (support taken, gets second choice)
```
```
// Team needs: 1 top, 1 jungle, 1 mid, 1 adc, 1 support
// Players with their preferences:
Player1: ["mid", "top", "support"] // Flexible
Player2: ["jungle"] // One-trick (gets priority!)
Player3: ["support", "adc"] // Support main
Player4: ["mid"] // Mid only
Player5: ["top", "mid", "jungle"] // Fill player
// Assignment result:
Player2 → jungle (most specific, only wants jungle)
Player4 → mid (most specific for mid)
Player3 → support (first preference available)
Player5 → top (mid/jungle taken, gets top)
Player1 → adc (forced to fill, but match succeeds!)
```

Also from the [Playflow Docs](https://docs.playflowcloud.com/unity/matchmaking#setting-role-preferences-in-code): "**Edge Case**: If too many players are inflexible (single role only) and want the same role, the match will fail. Always encourage some flexibility in your player base!"

### Multi Role in Unreal
In this, we are adding that we want to be Jungle and Toplane. once we have added these to our Role Selection Array, we do a join string array and then format it with open and closing brackets and set that in our Roles String Variable. Then we set that as our "role".
