Sorry in advance a little behind on versions.  I have a mod that makes it snow when an event is triggered.  I used to make it snow with this in 1.8.9:

 

                Biome b = BiomeRegistry.biomeGlistre;
                WorldServer worldServer = FMLCommonHandler.instance().getMinecraftServerInstance().getServer().worldServerForDimension(Defaults.DIM_ID.FREON);            
                WorldInfo worldinfo = worldServer.getWorldInfo();
                //first parameter is temp .2F and rain looks like snow, second parameter is rainfall 0F none .5F is normal)        
                    b.setTemperatureRainfall(0.0F, 1.0F);//// No longer works in 1.12.2!

 

Is there a replacement method for #setTemperatureRainfall or is there another way to do this? 

 

I still need to backport to 1.10.2 but anyone knowing how to do this for 1.10 -1.12 would help --- should I make a custom WeatherRenderer?

wrong forge version should be 1.12.2

I haven't tested this myself, but this is what I found. Use b.setTemperature(0.0F).setRainfall(0.5F).setSnowEnabled(); instead.

That might work in 1.10.2 using Biome.BiomeProperties I will try it.

In 1.12 I think I can access Biome::temperature using reflection.

Did you succeed? I have the same problem and have no idea how reflection works.

Don't necropost in old threads. If you have an issue make a new one.

Apart from that as the OP said you can modify Biome.temperature field's value using reflection. If you have no idea how reflection works then you should learn it.
