Mainly, there are differences in the MHFG low version network protocol when pkt.ShopType=1 or 2 in handleMgMhfEnumerationShop. Conducted code judgment and differentiation processing. If you need to configure the optional material list among the three options, Configure directly in gacha_detries The same Entry Type can be merged and displayed in GG In addition, the prizes are also directly configured in the gacha-entries table, MHFG1~GG does not use the gacha_items table throughout the entire process, which meets the lottery function of MHFG with a more single function In addition, the MHFG function itself is relatively simple Example of lottery configuration for G1~GG: eg: gachaname:test entry: itemgroup: group1:(choose one of the two) ITEM_1_ID:7 COUNT:1 ITEM_1_ID:8 COUNT:2 group2:ITEM_1_ID:9 COUNT:3 reward: reward1: ITEM_ID:1 COUNT:4 weight:10% reward1: ITEM_ID:2 COUNT:5 weight:90% table:gacha_shop |id|min_gr|min_hr|name|url_bannel|url_feature|url_thmubnail|wide|recommendded|gacha_type|hidden| |1|0|0|test|null|null|null|f|f|3|t| table:gacha_entries |id|gacha_id|entry_type|item_type|item_number|item_quantity|weight|rarity|rolls|frontier_points|daily_limit|name| |1|1|0|7|7|1|0|0|0|0|0|null| |4|1|0|7|8|2|0|0|0|0|0|null| |5|1|1|7|9|3|0|0|0|0|0|null| |8|1|100|7|1|4|1000|0|0|0|0|null| |9|1|100|7|2|5|9000|0|0|0|0|null|

如果需要在三个选项中配置可选素材列表里，

此外奖品也直接在gacha_entries表中配置，
|
||
MHFG1~GG全程不使用gacha_items表，已满足MHFG功能更单一的抽奖功能
|
||
此外，本身MHFG功能就比较单一
|
||
G1 ~ GG的抽奖配置 示例：
|
||
|
||
If you need to configure the optional material list among the three options,
|
||
Configure directly in gacha_detries
|
||
The same Entry Type can be merged and displayed in GG
|
||
In addition, the prizes are also directly configured in the gacha-entries table,
|
||
MHFG1~GG does not use the gacha_items table throughout the entire process, which meets the lottery function of MHFG with a more single function
|
||
In addition, the MHFG function itself is relatively simple
|
||
Example of lottery configuration for G1~GG:
|
||
eg:
|
||
gachaname:test
|
||
entry:
|
||
itemgroup:
|
||
group1:(choose one of the two) ITEM_1_ID:7 COUNT:1 ITEM_1_ID:8 COUNT:2
|
||
group2:ITEM_1_ID:9 COUNT:3
|
||
reward:
|
||
reward1: ITEM_ID:1 COUNT:4 weight:10%
|
||
reward1: ITEM_ID:2 COUNT:5 weight:90%
