TLHPoE

Characters weren't a problem I disabled all other mobs and loaded a world with my attributes. For some reason, whenever the break point hit at the snapshot class at world load, it was either maxHealth or speed. None of my attributes showed up. When I stepped up a block, the snapshot fired up and it was my step height attribute. I'm not sure what to make of this.

Ok, I'm looking through it right now. It seems that the server goes through all of the entity's attributes, saves them to a snap shot, sends the snapshot to the client, and the client syncs up with the server via the data from the snapshot. Not sure if I'm able to tell what the client is trying to sync there.

Here's my code: ModAttributes (I call the loadAttribute method in the pre initialization stage): package terrarium.entity.attribute; import net.minecraft.entity.ai.attributes.IAttribute; public class ModAttributes { public static IAttribute jumpHeight; public static IAttribute maxJumps; public static IAttribute stepHeight; public static IAttribute maxMana; public static IAttribute healthRegen; public static IAttribute manaRegen; public static IAttribute maxHurtResistantTime; public static void loadAttributes() { jumpHeight = (new ModAttribute("generic.jumpHeight", 0.41999998688697815D, true)).setShouldWatch(true); maxJumps = (new ModAttribute("generic.maxJumps", 1, true)).setShouldWatch(true); stepHeight = (new ModAttribute("generic.stepHeight", 1, false)).setShouldWatch(true); maxMana = (new ModAttribute("generic.maxMana", 20, true)).setShouldWatch(true); healthRegen = new ModAttribute("generic.healthRegen", 1, false); manaRegen = new ModAttribute("generic.manaRegen", 1.5, true); maxHurtResistantTime = new ModAttribute("generic.maxHurtResistantTime", 20, false); } } ModAttribute: package terrarium.entity.attribute; import net.minecraft.entity.ai.attributes.BaseAttribute; import terrarium.Reference; public class ModAttribute extends BaseAttribute { public boolean isPlayerOnly = false; public ModAttribute(String name, double defaultValue, boolean isPlayerOnly) { super(name, defaultValue); this.isPlayerOnly = isPlayerOnly; Reference.modAttributes.add(this); } @Override public double clampValue(double value) { return value; } } ForgeServerEventHandler: @SubscribeEvent public void entityConstruct(EntityConstructing event) { if(!event.entity.worldObj.isRemote) { if(event.entity instanceof EntityLivingBase) { EntityLivingBase entity = (EntityLivingBase) event.entity; boolean isPlayer = entity instanceof EntityPlayer; if(isPlayer) { ExtendedPlayerProperties.handlePropertiesFor((EntityPlayer) entity); } for(ModAttribute attribute : Reference.modAttributes) { if(attribute.isPlayerOnly && isPlayer) { entity.getAttributeMap().registerAttribute(attribute); } else if(!attribute.isPlayerOnly) { entity.getAttributeMap().registerAttribute(attribute); } } } } } Forgot the crash, sorry: ---- Minecraft Crash Report ---- // Ooh.

Ok, that didn't work either... I did some more debugging and I tried not loading my attributes. It didn't crash. All of my attributes' base values are not below their minimum value. Is their a maximum amount of attributes that I can have?

Hi, I get a crash about an attribute having a base value that's lower than the minimum value. It's in the NetHandlerPlayClient: iattributeinstance = baseattributemap.registerAttribute(new RangedAttribute(snapshot.func_151409_a(), 0.0D, 2.2250738585072014E-308D, Double.MAX_VALUE));

Ok, I traced it back to this line in NetHandlerPlayClient: iattributeinstance = baseattributemap.registerAttribute(new RangedAttribute(snapshot.func_151409_a(), 0.0D, 2.2250738585072014E-308D, Double.MAX_VALUE)); It's setting the base value to 0.0D and setting the minimum value to 2.2250738585072014E-308D; Is this just a forge problem? Or is it caused by me somehow?

Configuration config = new Configuration(event.getSuggestedConfigurationFile(), true); config.load(); config.get("Booleans", "Boolean1", false).set(true); config.save();

Oh, didn't see that part. You could give invisibility to the player and then spawn the entity/set the block at the player's location.

That's a bit too extreme for what you're trying to accomplish. Just cancel the RenderPlayerEvent and then do your own rendering.

You're telling WorldGenMinable to replace stone. new WorldGenMinable(block, (minVainSize + random.nextInt(maxVainSize - minVainSize)), Blocks.stone).generate(world, random, posX, posY, posZ);

Hi, I'm using this code to draw a filled circle at the given coordinates with the block that's given: public static void fillCircle(World world, int x, int y, int z, int radius, Block block) { while(radius != 0) { for(int i = 0; i < 360; i++){ world.setBlock((int) (x + radius * Math.cos(i)), y, (int) (z + radius * Math.sin(i)), block); } radius--; } } The above code isn't the most efficient (I think) and sometimes produces this: at some radius sizes. Is there any other efficient way of doing this?

Well, the print is firing. I've also tried registering it on the server side and checking if the world is remote, but the world is never remote. Nothing more. Ok, after some debugging I've discovered some things. 1. The world on both sides aren't remote 2. The server side event is only called from the server (I was expecting it to call on the client and server thread)

What I'm trying to achieve is the "reddust" particle being spawned 4 times each time a living entity is hurt. For some reason, nothing happens. package terrarium.handler.event; import net.minecraft.entity.EntityLivingBase; import net.minecraftforge.event.entity.living.LivingHurtEvent; import terrarium.util.LogUtil; import cpw.mods.fml.common.eventhandler.SubscribeEvent; public class ForgeClientEventHandler { @SubscribeEvent public void entityHurt(LivingHurtEvent event) { EntityLivingBase entity = event.entityLiving; LogUtil.info("HI"); for(int i = 0; i < 4; i++) { entity.worldObj.spawnParticle("reddust", entity.posX, entity.posY, entity.posZ, 0, 0, 0); } } } The class is registered on the client side in MinecraftForge.EVENT_BUS, and it's printing "HI" in the console whenever I hit an entity. Am I missing something obvious?

I'm replacing the computeLightValue method in the World class. What I'm trying to accomplish is adding a new check for how many solid blocks and air blocks stand inbetween the the block it's computing the light value for and the block at the top that can see the sky. Then I'll use that information to somehow alter the light value so that something floating high above the air won't cast the largest shadow on earth.

Thanks, both links are very helpful.

Oh, I didn't know that the inventory was synced with the client.

Hi, I'm using the ItemTooltipEvent to add some more information to itemstacks in my gui. The problem is, I need to get either the slot or the inventory in which the itemstack is inside of. I have my own crafting system that collects information on how much of what itemstack is in the player's inventory and displays what the player can craft. The reason I need the slot/inventory, is because I want to add the ingredients of the recipe to the itemstack tooltip. If there's any other way of doing this, I'm all ears.

Are there any tutorials that cover creating a coremod and writing in ASM?

What version of Minecraft are you using? That method doesn't seem to exist in 1.7.10...

I think this is what you're looking for: this.setTickRandomly(true);

Hi, I'm pretty sure I need to replace a method in the World class, seeing as I don't know how else to do it. I know ASM is used to make methods public, but it can also modify/replace the method itself? I've looked here for an idea on how to do it, but EventTransformer does not exist in 1.7.10. So do any of you know of a tutorial that can still be used in 1.7.10?

After reading all of the replies, I'll try spawning blocks bellow my island that give off sunlight, since I use vanilla blocks to generate my island. If I can't do that, creating the new sky ceiling will be my next option.

Hi, in my mod I generate floating islands: Is there anyway to allow sky light to go through the island and stop the large shadow?
