I have acctually done huge progress so most of it is solved, the issue seems to be more metadata related now. Anotehr example I worked throughout the day is a pressure gauge pipe that generates a redstone signal who's strength depends on the pressure inside, the metadata of the pipe changes and as such generates more redstone power but the redstone connected doesn't react to the new strength, when I remove the closest redstone and replace it it goes as far as it should though.

Tileentity alone? or what else would you like to see?

Alright, I have managed to solve it but I have the issue of metadata of a block (which changes as the steam pressure increases) starts at 0 when the world is loaded and remains at 0 until it changes from it's data point (let's say the pressure is 2 for the sake of arguement) and then when ti changes to 3, the client gets the change and shows correct but until then it does not. How would I fix that?

hmmmm what happens if server side and client side tries to process different data for the same tile entity? Will that cause trouble?

it probably does but what could cause them to go so much out of sync?

Hello, I am doing my mod where I have steam being generated, I know the differens between server/client and .isRemote and such but the server and client get's out of sync where one side has more or less steam than the other, shouldn't it be equal? Is there a way to make them update more or? This especially occures for tileentity data that is saved onto the server but then not loaded into the client (I have checked the data, they are close to identical when it starts, I save and quit and then reopen and the client side has low data while the server data is where it should be, having been saved) Kind Regards

It worked, thanks!

I have it ogg, which format should it be?

Hello, I try to play a sound when ablock is activated and nothing happens. I hear nothing and I get this errorcode Error in class 'LibraryLWJGLOpenAL' Sound buffer null in method 'loadSound' Error in class 'LibraryLWJGLOpenAL' Source '6234ecc8-b453-46d5-8d3f-e459ba6b4e45' was not created because an error occurred while loading aerosteam:sounds/activatetransaltituder.ogg Error in class 'LibraryLWJGLOpenAL' Source '6234ecc8-b453-46d5-8d3f-e459ba6b4e45' not found in method 'play' and in sounds.json I have { "activatetransaltituder": {"category": "master","sounds": [{"name": "activatetransaltituder","stream": false}]} } and the block code of relevans is if (playerX < x+addX+1 && playerX > x+addX-1 && playerZ < z+addZ+1 && playerZ > z+addZ-1){ System.out.println("Within"); player.setPositionAndUpdate(playerX, height +1 , playerZ); world.playSoundAtEntity(player, "aerosteam:activatetransaltituder", 1, 1); } I have checked it is located in my \forge\src\main\java\assets\aerosteam\sounds folder, what am I doing wrong?

But how owuld I go about that birch planks gives one type and Oak plank gives another?

Hiya! I am trying to make pipes contained within blanks which requires some minor modification of appearence depending on the source plank being used GameRegistry.addShapelessRecipe(new ItemStack(BlocksPipes.pipeBirchPlankStraight),new Object[]{Blocks.planks}); I am trying to use this but I know that planks different appearence depends on the metadata and I am not certain how to change the recipe depending on the input plank, I could change the thing so it acquires the metadata aswell and works the same way planks do, BUT I am not certain how to transfer the metadata there aswell, could I get some suggestions or direction that could make htis possible so I can move forward? I like trying things but now, I am stumped.

I have photoshop and it is transperent, but it doesn't show up as transparent. canRenderInPass(pass) should _not_ always return true -- you only want it to be able to render in pass 1 (not pass 0). Use this: @Override public boolean canRenderInPass(int pass) { return pass == 1; } This pisses me off, mostly that it was so simple =_= It worked, thank you!

I have locked there acctually care to define what "IBSRH" is? But both of those functions are overriden and canRenderInPass = true constantly and getRenderBlockPass = 1 aswell which is what confuses me

I am trying to render transparent gas but the blocks are either not transparent or fully tansparent, not inbetween like I want As you can see here, the block is not transparent but the item has the half transparency in it. package aerosteam.gases;

from my experience it is wise to avoid using sin/cos at all costs if possible as they are heavy on processing, you might wanna read up some on linear algebra to help you aswell

Added if clause to the colour part same as the one below

Nevermind Solved it!

Dear Lord That shit works! I gotta figure out how to detect the player in the gases but thank you! that was exacly what I wnated

I am working on creating gases at which I want the players view to change when the player is inside the gas, just like hwen it is in water. I am currently searching through the fluid water stuff to get some ideas how to but I am currently at a loss, how would I change colours, distory the general rendering and such like in water and stuff?

oohh Not Java 8!

You mean this? http://www.minecraftforge.net/forum/index.php/topic,20.0.html What in it are you specificly aiming at?

I just found it and posted it sorry!

public class AnvilSlots extends SlotCrafting{ public AnvilSlots(EntityPlayer p_i1823_1_, IInventory p_i1823_2_, IInventory p_i1823_3_, int p_i1823_4_, int p_i1823_5_, int p_i1823_6_) { super(p_i1823_1_, p_i1823_2_, p_i1823_3_, p_i1823_4_, p_i1823_5_, p_i1823_6_); // TODO Auto-generated constructor stub } @Override public void onPickupFromSlot(EntityPlayer player, ItemStack p_82870_2_) { System.out.println("slot changed"); this.onSlotChanged(); } } I tried this and I get it to work to the extent it reacts whenever something happens to the slot in question, the crafting slot one where the result appears, works marveously. But....I am uncertain how to get it to act on the other slots. public ContainerAnvil(InventoryPlayer inventory,TileEntityAnvil tileentity, World world, int x, int y, int z){ this.anvil=tileentity; craftMatrix = new InventoryCrafting(this, 2,3); craftResult = new InventoryCraftResult(); worldObj=world; this.posX=x; this.posY=y; this.posZ=z; //Hammer slot this.addSlotToContainer(new Slot(tileentity,0,116,13)); for (int i = 0; i<2;i++){ for (int j = 0; j<3;j++){ this.addSlotToContainer(new Slot(craftMatrix,(i*3+j),21+18*j,33+18*i)); } } this.addSlotToContainer(new AnvilSlots(inventory.player, craftMatrix,craftResult, 1,136,42)); for(int i=0; i<3;i++){ for(int j=0; j<9;j++){ this.addSlotToContainer(new Slot(inventory,j+i*9+9,7+18*j+1,83+18*i+1 )); } } for(int i=0;i<9;i++){ this.addSlotToContainer(new Slot(inventory,i,8+18*i,142)); } onCraftMatrixChanged(craftMatrix); } public void onCraftMatrixChanged(IInventory inventory){ //System.out.println("Craft Change"); Slot slot = (Slot)this.inventorySlots.get(0); if (slot != null && slot.getHasStack()){ Item item = slot.getStack().getItem(); if (slot.getStack().getItem() != null){ if (slot.getStack().getItem() == ItemsAS.hammerBronze){ //System.out.println("has hammer"); craftResult.setInventorySlotContents(7, AnvilSmithManager.getInstance().findMatchingRecipe(craftMatrix,worldObj)); } } } //System.out.println("Done matching"); } The part I have changed is the one where the result is shown, perhaps I need to change all of them? Either how this is a great leap forward for me, what I want it to affect when the slot changes is slot 0 that is first generated, how would I access it from the slothchanged function?
