I ended up using the first algorithm and ignoring the "closed edge" problem. I also make the checks more efficient by storing the edge as a Map<Xpos, Set<Zpos>>. However, it seems that the area found is not correct (includes only the edge, but the edge that gets printed to the log is incomplete). I feel that I missed something obvious Code on GitHub because reading code on the forums is painful Edit: Yup, that was it: a few copy-paste derps in setting the NW and SE blocks.

that... is a surprisingly simple algorithm, considering all I could think of involved vector math (and wouldn't work). always google first the only issue I see here is speed, since it looks like I'll have to iterate through all blocks within the "bounding rectangle" of the polygon, then check if it is on the inside, which involves iterating through all blocks on the outline (so at least width*height*perimeter checks). I have a similar concern with the check to make sure the border is actually closed. Not sure if something can be done about that though.

That would only work if the area was rectangular... The problem is that I can't know what the shape will be... all we have is the coordinates of the blocks that form the outline (which are connected), as well as the coordinates of a block somewhere inside the shape

Hello I am creating a "block" that lifts terrain around it. The area to lift is defined by placing "marker" blocks in a connected shape that encloses the "lifter" block, on the same Y level. This has raised a few interesting questions: 1) Finding the outline: This is the easy part, just search in any/all cardinal directions until a marker block is found (or a max distance is reached), then recursively find all connected marker blocks. 2) Making sure the outline is a closed shape around the lifter: I would do this by making sure there is a marker block in all cardinal directions around the block, then checking that all marker blocks previously found have at least 2 other marker blocks connected to them. However, that looks like it could be slow. 3) Finding the area inside the outline This is the part I don't know how to do, and also the more "general" problem: given a 2D grid with a known outline (and a "center" point), how to find the coordinates of all squares inside that outline? Thoughts?

And I suppose an improper way to do this would include hacking into world#setBlockState and checking if the call stack contains WorldGenerator#generate, which I presume would make a lot of things laggy AF and crash the others

That's an option, although it reduces even more the number of mods that I will be able to handle, since they have to both fire the event and extend WorldGenMinable (even vanilla's BiomeHills$EmeraldGenerator is just a WorldGenerator)

Hello I am trying to prevent ore generation on a per block basis. I looked into OreGenEvent, but there does not seem to be a way to find out what is being generated from the WorldGenerator instance, other than guessing from the class name. My thought would be to "intercept" or look for calls to World#setBlockState that happen in WorldGenerator#generate, check the BlockState being set and use that to cancel the ore generation. Of course, that looks like massive hackery from the deepest pits of coremodding, and I have no clue where to start about that. Any thoughts?

Yes, except that it does not have a release since 1.7.10. I thought that since Forge added modifiers for keybinds, a search bar would be a logical thing to add, especially for finding the few keybinds I change in every new instance

With large packs, there can be a lot of keybindings to scroll through. I think a search bar (possibly with a "show only conflicting" option) would improve usability.

got it working, thanks!

I'll look into that EnderIO.weather_rocket . Also, I plan to optionally load the map from a JSON file to allow pack makers/users to tweak it if necessary. Do you think there would be a significant performance difference between loading the JSON and iterating through the LootTables? I want to figure out what should be the default Also, I'm getting that NPE even when initialising the map lazily: 2016-06-03 14:44:16,216 WARN Unable to instantiate org.fusesource.jansi.WindowsAnsiOutputStream 2016-06-03 14:44:16,216 WARN Unable to instantiate org.fusesource.jansi.WindowsAnsiOutputStream [14:44:16] [main/INFO] [GradleStart]: Extra: [] [14:44:16] [main/INFO] [GradleStart]: Running with arguments: [--userProperties, {}, --assetsDir, C:/Users/Felix/.gradle/caches/minecraft/assets, --assetIndex, 1.9, --accessToken{REDACTED}, --version, 1.9.4, --tweakClass, net.minecraftforge.fml.common.launcher.FMLTweaker, --tweakClass, net.minecraftforge.gradle.tweakers.CoremodTweaker] [14:44:16] [main/INFO] [LaunchWrapper]: Loading tweak class name net.minecraftforge.fml.common.launcher.FMLTweaker [14:44:16] [main/INFO] [LaunchWrapper]: Using primary tweak class name net.minecraftforge.fml.common.launcher.FMLTweaker [14:44:16] [main/INFO] [LaunchWrapper]: Loading tweak class name net.minecraftforge.gradle.tweakers.CoremodTweaker [14:44:16] [main/INFO] [LaunchWrapper]: Calling tweak class net.minecraftforge.fml.common.launcher.FMLTweaker [14:44:16] [main/INFO] [FML]: Forge Mod Loader version 12.17.0.1937 for Minecraft 1.9.4 loading [14:44:16] [main/INFO] [FML]: Java is Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_91, running on Windows 7:amd64:6.1, installed at C:\Program Files\Java\jre1.8.0_91 [14:44:16] [main/INFO] [FML]: Managed to load a deobfuscated Minecraft name- we are in a deobfuscated environment.

No clue what the entity ID is, all I gave is that crash report (well, I have another similar one with its server log), because I was unable to reproduce the crash even with the same Forge version, so I figure they must have another mod being stupid.

It seems to be happening I've had two bug reports with a crashlog like this on a dedicated server (Forge 1935 and 1937), the line from my mod being a call to EntityList#createEntityByName. couldn't reproduce them though I'm not sure I completely understand what you mean here... LootTables provide the entity -> drops information. Because what I need is the drops -> entity, I iterate through all living entities to get their possible drops and build a map for [item name + meta] ->

I guess I'll keep my catch(NoClassDefFoundError e) then My issue now seems to be when should I build my map. I was doing it on WorldEvent.Load, but I get a NPE when grabbing the LootTable Description: Exception in server tick loop java.lang.NullPointerException: Exception in server tick loop at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:213) at com.google.common.cache.LocalCache.get(LocalCache.java:3933) at com.google.common.cache.LocalCache.getOrLoad(LocalCache.java:3938) at com.google.common.cache.LocalCache$LocalLoadingCache.get(LocalCache.java:4821) at com.google.common.cache.LocalCache$LocalLoadingCache.getUnchecked(LocalCache.java:4827) at net.minecraft.world.storage.loot.LootTableManager.getLootTableFromLocation(LootTableManager.java:39) at xilef11.mc.runesofwizardry_classics.runes.RuneResurrection.getEntityLoot_Table(RuneResurrection.java:167) at xilef11.mc.runesofwizardry_classics.runes.RuneResurrection.initDropsTable_entity(RuneResurrection.java:144) at xilef11.mc.runesofwizardry_classics.runes.RuneResurrection.initDropsTable(RuneResurrection.java:121) at net.minecraftforge.fml.common.eventhandler.ASMEventHandler_11_RuneResurrection_initDropsTable_Load.invoke(.dynamic) at net.minecraftforge.fml.common.eventhandler.ASMEventHandler.invoke(ASMEventHandler.java:49) at net.minecraftforge.fml.common.eventhandler.EventBus.post(EventBus.java:140) at net.minecraft.server.integrated.IntegratedServer.loadAllWorlds(IntegratedServer.java:96) at net.minecraft.server.integrated.IntegratedServer.startServer(IntegratedServer.java:123) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:494) at java.lang.Thread.run(Unknown Source)

I think I got something that could work (didn't test yet), but it annoys me that I still have to create the entity, because I've had a few reports of dedicated servers crashing because the "particle" entity ended up on the entity list

Hello I need to go from an ItemStack to a list of mobs that might drop it. I currently have this very hacky way of building an Item->entity map, and I want to switch it to Loot Tables for everyone's sanity I asked the author of NotEnoughResources, and he pointed me to this and this, but I'm having a hard time figuring it out. Thanks for the help

I had it set up in NetBeans a while back using the gradle plugin. copied from one of my mods' readme: NetBeans (not tested for the MC 1.8 version): Install the gradle plugin for NetBeans Go to Tools->Settings->Misc->gradle and change "build script evaluation" to "Idea based [...]" Open a command prompt from the repository folder. Run the commands 'gradlew setupDecompWorkspace' (will take a while) and 'gradlew idea'. Open the project folder in NetBeans In "project properties", go to "manage built-in tasks" In the "run" task, uncheck inherited and change run to runClient Done! hope it helps!

I did a few more tests, and I think I found a possible cause for the problem: In the addon's @Mod annotation, it seems that putting 'required-after' instead of 'required-before' for the dependency on the library prevents the NoClassDefFound exception. (I don't see how the load order affects the classpath, but that's a side of Forge I don't know about ) However, this causes a problem: It is necessary that all addons have completed their preinit sequence before the library. This is because the library will register a custom model for some of the addon's items, which must be done in preinit (as well as registering items). (It is also preferable that the addons complete their init and postinit sequences before the library) A solution could obviously be to have a method in the library to register the custom models and make the addons call it during preinit, but I don't think it is very elegant because it requires extra work on the addon's side for the "normal" behaviour. Is there an explanation or solution for this problem?

I've been messing around with this a bit more, and I can't figure out what's wrong... My guess is that something is not being built properly, but I can't find what. Build script for deobf jar Build script for the addon All three (deobf, normal and addon) jar files: http://ge.tt/7zcR9jZ2 Once again, everything builds properly with deobf jar in ./libs, but crashes with normal + addon jars in a normal minecraft instance

Here it is. Also, the code for the addon: https://github.com/Xilef11/runesofwizardry-classics

not core as in coremod, core as in "library"

no, the class that's not found is in the jar file (which is the weird part), and it is under src/main/java/ in the dev workspace

Hello I have two mods I have been developing in parallel: a "core" Library and an "addon". During development, I had both mods in the same workspace and added the core library project to the build path of the addon project and everything worked perfectly. In order to build the addon project via gradle, I had to make a deobf jar of the core library and put it in ./libs (I thought a deobf version was no longer necessary because FG deobfuscated at runtime, but it wouldn't compile otherwise). Once again, everything builds and runs perfectly under gradle (gradlew runClient) However, when I try to run both mods (the normal, obfuscated versions) in a normal Minecraft instance, I get the following crash: http://pastebin.com/cgmkhTJw The error seems to be the addon complaining about a "missing" class in the core library, but that class does exist in the jar that is in the mods folder. I have tried rebuilding both mods a few times and checking that all classes were correctly compiled and included in the jar, and I tried running in both MultiMC and the Curse launcher, but I can't figure out why its not working. Any ideas?

I got it working, thanks for the feedback everyone!

ok. How do I bind different TileEntities to different BlockStates? My Block currently only implements ITileEntityProvider, and createNewTileEntity only has a metadata param, not a BlockState.
