## Abstract
This PR implements
- The Gacha System for client. Player can pull in defined pools with a similar experience to zenless & mihoyo gacha, and these status can be saved through player save and recovered.
- `player kick` command in extra. Command `player kick [player_uid] (optional: [reason_id])` can be used to kick a player to offline.
## Support list
- Similar probability to mihoyo gacha
- QingYi & Jane Doe's Agent & W-Engine banner
- Standard Banner:
- Get a S Agent in the first 50 pulls
- Get a 20% discount for the first 5 10-pulls
- Choose a S Agent once you pulled for 300
- ~~Bangboo Banner~~ (not working due to other reasons)
- Choosing your demanded S bangboo for 100% UP
## Principle
- A complex configuration file `gacha.jsonc` is introduced to define all behaviours.
- Gacha status is saved via `GachaModelBin`.
For more informations about the config and save, an article is available [here](https://yyheggegg.github.io/mihomo-gio-blogs/zzz-gacha-impl-en/).
## Known issues
- You can not see any bangboos in the collection when choosing Bangboo.
- **Specifically for 1.1 Beta**, performing gacha may lead to random client issues, including:
- The TVs showing rarity ending up in blank after its flash.
- Game become black screen.
- If clicking 'Skip' but not fast enough, game'll stuck and not able to do anything. You may try to click 'Skip' scarcely when 'REC' shows, or after all animations has stopped.
