I found the problem, so for future reference I accidentally put the spawning code inside of the server code. I moved it to client side, and everything works now.

Any ideas, school's kept me from looking too much deeper, but if it helps this time the error was reported with chickens instead of my item. net.minecraft.util.ReportedException: Ticking entity

Namely, I have a delay of one second on my item between allowed uses. I also tried surrounding the line in question (this.moveEntity(this.motionX, this.motionY, this.motionZ)) in a try/catch that called this.setDead() if it threw an exception, but that just threw an exception faster. Does anyone have an idea why this may happen?

I'll see what I can find out about the fluid height. Also, the Fluid f is a local variable stored only within the load method. I made the call to FluidRegistry to check if the fluid was being properly registered (and because BuildCraft does it), then I save the registered fluid into a static global field. Also, worth noting is that forge fluids do not extend any vanilla classes (other than block of course) Edit: also, the player DOES drown when they're inside the fluid, and it IS set to water. The problem is that it has an "air pocket" between each block that lets the player breathe for a second every time their head reaches a new block.

So, recently I have been trying to create a fluid. I have tracked down many of the bugs, after some serious searching I might add, and I have eliminated nearly all of them. There are only two more things that I have noticed: one bug, and one is just more of a complaint. The complaint is that the screen overlay is blue, and my liquid is yellow. Is there a way to change the overlay (fairly) easily? Now on to the bug: When swimming in my fluid, each time the player's head reaches another block, it refreshes the Oxygen meter, so it's impossible to drown in the fluid. Side Note: I also noticed that always returns true in the code below. What's happening there? Threading issue? Info on the fluid: Most of this is copied from Build Craft's GitHub. Since the block class is verbatim at the moment, I'll just provide the github link: https://github.com/BuildCraft/BuildCraft/blob/master/common/buildcraft/energy/BlockBuildcraftFluid.java Fluid f = new Fluid("LINSEED_OIL").setDensity(800).setViscosity(1500); FluidRegistry.registerFluid(f); linseedOil = FluidRegistry.getFluid("LINSEED_OIL") == null? f:FluidRegistry.getFluid("LINSEED_OIL"); if(linseedOil.getBlockID() == -1){ if(linseedOilID > 0){ linseedOilBlock = new LinseedOilBlock(linseedOilID, linseedOil, Material.water).setUnlocalizedName("linseedOilBlock"); } } else { linseedOilBlock = Block.blocksList[linseedOil.getBlockID()]; }

That basically didn't help at all, but I'm going to assume that you meant I'm OK to leave the block value at 4000. Also, I think it should be known that I do in fact understand the fact that bytes are an 8-bit storage method, and that integers are 32-bit, I also understand what that means. However, saying that these have to do this, without really specifying further, is no better than every mom's favorite phrase: "Because I said so".

When should you use this function? I know what the documentation says, but it means nothing to me: The only world generation I add currently/plan to add, is a single new species of flower. I ran some tests having it's ID in the 4000 range, and it IS placing it in the world; however, it is not consistent in the frequency, like it was while testing with the ID at 255 (can't tell if the two events were just a coincidence yet). Does a new variety of flower count as "low level terrain generation"?

This github may be useful to you: https://github.com/jadar/DeveloperCapes I did not create any of this: full disclaimer; however, you can either package it with your mod, or you can use it to shine some light on your problem.

Thank you for the response, I figured when it specifically mentioned skipping the deobfuscation that it did. I just wanted to hear it from someone with a bit more experience with the API.

Hey, I just started my first mod about two weeks ago, and I think I have another three weeks of work before I'm ready for an alpha release. Anyway, I see this in the console every time I run my client: 2013-08-03 23:52:13 [iNFO] [ForgeModLoader] Managed to load a deobfuscated Minecraft name- we are in a deobfuscated environment. Skipping runtime deobfuscation I am aware that this isn't an error of any sort, and I am aware of what obfuscation means, so please have a little faith in me. My question is does Forge do runtime deobfuscation? It matters to my mod, because I am doing some reflection, and I really don't want to compile my mod right now to test if it throws any exceptions. http://docs.oracle.com/javase/7/docs/api/java/lang/reflect/package-summary.html (In case anyone doesn't know what reflection is) I am aware that Access Transformers do even more than this, but they are a lot more work for me to learn about, and I would like to push the release as soon as possible since I go back to school next week. (Yes I intend to deploy Access Transformers later as part of a source clean-up) Also, in case anyone is too curious why I need reflection, I am creating a flower pot interface for my mod (eventually doing an API) to add new flowers to the flower pot renderer, and reflection is the easiest way I know to strip the final modifier from the field in Block. In summary, can I reference the non-obfuscated names in my code without worrying about major bugs and crashes?

Hey, just wanted to report that I had this problem as well. Do you think this is a bug with forge, or are we just going to have to live with it? [EDIT] I should have run my tests before my OP, but oh well. The code above fixed the picking up mechanic, but I can't get my bucket to place in the world. I'll try something really quick, but it's looking to be a much bigger headache than it should be. [EDIT] I got it to work, but I had to entirely circumvent Forge's Item Containers. I find it is best to use a class extending ItemBucket, and apply the above patch note to that class. The FluidContainerRegistry doesn't appear to serve any function beyond compatibility, but I think that I'd rather live with a few complaints on it not playing nice with other mods than live with a buggy, broken item. The source that solved my problem: (names changed) package mod.yourmod.item; import net.minecraft.item.ItemBucket; import net.minecraft.item.ItemStack; import net.minecraft.util.MovingObjectPosition; import net.minecraft.world.World; import net.minecraftforge.common.MinecraftForge; import net.minecraftforge.event.Event.Result; import net.minecraftforge.event.ForgeSubscribe; import net.minecraftforge.event.entity.player.FillBucketEvent; public class CustomBucketItem extends ItemBucket{ public Block contains; public CustomBucketItem(int itemID, Block contains) { super(itemID, contains.blockID); this.contains = contains; MinecraftForge.EVENT_BUS.register(this); } @ForgeSubscribe public void onBucketFill(FillBucketEvent event) { ItemStack result = fillCustomBucket(event.world, event.target); if (result == null) return; event.result = result; event.setResult(Result.ALLOW); } public ItemStack fillCustomBucket(World world, MovingObjectPosition pos) { int blockID = world.getBlockId(pos.blockX, pos.blockY, pos.blockZ); if ((blockID == contains.blockID) && world.getBlockMetadata(pos.blockX, pos.blockY, pos.blockZ) == 0) { world.setBlock(pos.blockX, pos.blockY, pos.blockZ, 0); return new ItemStack(this); } else return null; } } And I would just like to say that this doesn't feel like a solution, it feels like a bandage that I'll have to redress later.
