# Potential avalanche from local lag
Under the current "input delay" algorithm, the lag of a single player would cause all the other players to receive outdated commands, e.g. when at a certain moment
- player#1: renderFrameId = 100, significantly lagged due to local CPU overheated
- player#2: renderFrameId = 240
@ -9,3 +10,34 @@ players #2, #3 #4 would receive "outdated(in their subjective feelings) but all-
In a "no-server & p2p" setup, I couldn't think of a proper way to cope with such edge case. Solely on the frontend we could only mitigate the impact to players #2, #3, #4, e.g. a potential lag due to "large range of frame-chasing" is proactively avoided in `<proj-root>/frontend/assets/scripts/Map.js, function update(dt)`.
However in a "server as authority" setup, the server could force confirming an inputFrame without player#1's upsync, and notify player#1 to apply a "roomDownsyncFrame" as well as drop all its outdated local inputFrames.
# Start up frames
renderFrameId | generatedInputFrameId | toApplyInputFrameId
-------------------|----------------------------|----------------------
0, 1, 2, 3 | 0, _EMP_, _EMP_, _EMP_ | 0
4, 5, 6, 7 | 1, _EMP_, _EMP_, _EMP_ | 0
8, 9, 10, 11 | 2, _EMP_, _EMP_, _EMP_ | 1
12, 13, 14, 15 | 3, _EMP_, _EMP_, _EMP_ | 2
It should be reasonable to assume that inputFrameId=0 is always of all-empty content, because human has no chance of clicking at the very first render frame.
# Alignment of the current setup
The following setup is chosen deliberately for some "%4" number coincidence.
- NstDelayFrames = 2
- InputDelayFrames = 4
- InputScaleFrames = 2
If "InputDelayFrames" is changed, the impact would be as follows, kindly note that "372%4 == 0".

You can use [this node module (still under development)](https://github.com/genxium/node-mysqldiff-bridge) instead under `Windows10`, other versions of Windows are not yet tested for compatibility.

For `Windows 10/11`, you can compile `skeema` from source and config the host to be `127.0.0.1` instead of `localhost` to use it, i.e. circumventing the pitfall for MySQL unix socket connection on Windows.

### 2.3.1 Backend

- It needs `<proj-root>/battle_srv/configs/*` which is generated by `cd <proj-root>/battle_srv && cp -r ./configs.template ./configs` and necessary customization.
### 2.3.2 Frontend
### 1.3.2 Frontend
- It needs CocosCreator v2.2.1 to build.
- A required "CocosCreator plugin `i18n`" is already enclosed in the project, if you have a globally installed "CocosCreator plugin `i18n`"(often located at `$HOME/.CocosCreator/packages/`) they should be OK to co-exist.
- It needs `<proj-root>/frontend/assets/plugin_scripts/conf.js` which is generated by `cd <proj-root>/frontend/assets/plugin_scripts && cp conf.js.template conf.js`.
