How to set one weather region for whole map? SA

[Ryba15]

Hi, I mean how to disable LS, SF, LV, and Bone Couty weather regions, to use only Countryside weather region for whole game world. I found LV,SF,BC regions boundaries(0072A686, 0072A6F5, 0072A6B5)(without boundary on map edge(3000/-3000)) in exe, but I don't know what exacly I can do with it.. : - )

For now I only overwrite memory by cleo script in 008D5EB0 to set own weathers for countryside region.

You found the CWeather::UpdateWeatherRegion function, which updates current weather region (CWeather::WeatherRegion) according to camera position:

 

 

I think the best solution here is to hook all CWeather::UpdateWeatherRegion calls and assign your value to CWeather::WeatherRegion:

 

#include "plugin.h"#include "CWeather.h"using namespace plugin;class MyWeatherRegion {public:    MyWeatherRegion() {        static CdeclEvent<AddressList<0x72A7A4, H_CALL,  // this list contains                                      0x72B85E, H_CALL,  // all exe addresses where                                      0x72B8B4, H_CALL>, // CWeather::UpdateWeatherRegion is called            PRIORITY_AFTER, ArgPickNone, void(CVector*)> myOnUpdateWeatherRegion;        myOnUpdateWeatherRegion += [] { // this code will be executed directly after CWeather::UpdateWeatherRegion call            CWeather::WeatherRegion = WEATHER_REGION_DESERT;        };    }} myWeatherRegion;

Yet another way is to completely replace CWeather::UpdateWeatherRegion with your own function:

 

#include "plugin.h"#include "CWeather.h"using namespace plugin;class MyWeatherRegion {public:    static void MyUpdateWeatherRegion(CVector*) {        CWeather::WeatherRegion = WEATHER_REGION_DESERT;    }    MyWeatherRegion() {        patch::RedirectJump(0x72A640, MyUpdateWeatherRegion); // replace original function with your function    }} myWeatherRegion;

It's look very clearly, but it's will work without any additional plugins? (for example I can't find CWeather in exe)

How are you going to patch exe without 'additional plugins'?

I compared UpdateWeatherRegion function from your screenshot with what I see in my screen, read about plugins on your github site, and now I know that I tried to do it the wrong way.
