I am intercepting a LivingUpdateEvent, and have accessed event.getEntity.getWorld(), but don't know where to go from here. So far, I have found world#isRaining, but not one for snowing, so I figure I check if it is raining and if the biome is cold, but how do I find the biome? I suspect I can do this with the chunk provider, but I'm not sure, since all of the methods I've found on GitHub or past forums seems to make references to outdated fields (I even checked MCPBot to see if I could find some of these fields obfuscated, to no avail). Specifically, I can't seem to call world#getBiome

 

Edit: As of now, I have found World#func_226691_t_ which seems to return a biome given a BlockPos. From this I have:

world.func_226691_t_(player.getPosition()).getPrecipitation() == Biome.RainType.SNOW

 

 

However, this seems to only check the type of precipitation, not when it is precipitating.

My recommendation would be to use World#isRaining in conjunction with Biome#getTemperature (with the biome obtained via World#getBiome). Though, it sounds like you're already doing that; why won't getBiome work for you?

 

Edit: My bad, I was a little too hasty; I've edited my answer.

I'm not sure why, Eclipse is telling me net.minecraft.world.World has no method called getBiome. This is odd since the 1.15 source code I've seen have accessed it.

Sounds like an issue of using outdated MCP mappings. Make sure you're using the latest snapshot version (20200513-1.15.1 at the time of writing this).

Makes sense, considering I used the methods.csv of the latest snapshot to find World#func_226691_t_ in the first place :)

Unfortunately, I have never had to do this before. I changed the build.gradle accordingly:

mappings channel: 'snapshot', version: '20200513-1.15.1'

 

 then ran ./gradlew genRunEclipse, ./gradlew eclipse and ./gradlew --refresh-dependencies with success. This didn't invalidate the references I had before and what should be the updated references still don't work :/ am I missing a step?

 

Edit:

 

ExampleMod/src/main/java/com/jacobdil/dillmod/entity/ai/goal/CollideGoal.java:174: error: cannot find symbol
                    return this.world.func_226665_a__(this.entity, this.entity.getBoundingBox().offset(blockpos));
                                     ^
  symbol:   method func_226665_a__(MobEntity,AxisAlignedBB)
  location: variable world of type IWorldReader

 

That looks promising, but if only my IDE would follow along!

Hmm, I don't use Eclipse myself so I'm not entirely sure if it's a problem with that or if it's something else... All I usually have to do is press a button which re-imports the Gradle project (I use IntelliJ IDEA). Not sure if Eclipse has a similar function somewhere.

 

You could also try deleting your Gradle cache to force it to refresh. There should be a .gradle folder in your computer's user directory, all you should have to do is delete the caches folder. Not sure if it'll work as I expect, but it may be worth a shot if you can't figure out anything else (unless someone who knows Eclipse better than me can provide some tips).

It seems like I'm learning, since I did think to try this, and it worked! Thank you so much, you're a champ

Have you tried Right Click on Project -> Refresh?

Eclipse does not automatically refresh if there are changes done on the disk (that is not managed by Eclipse).

Seems to be fixed.

Some tips:

Spoiler

Modder Support:

Spoiler

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

4. 

Quote

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

6.

Quote

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:

Spoiler

1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
