All entities have a coordinate that they are on, my question is when it comes to mobs. Where is their X, Y, Z position located relative to the model? Is it squirely in the center, at the center horisontally but at the bottom? or maybe top?

You mean in the container for the crafting grid? How would I use a custom implementation if so? Imma try the slotcrafting first though

I work on my crafting table and I get it to produce anything I so want but none of the resources are being removed, I am a bit stumped and don't even know where to look in the code. Got any hints what part could be the culprit? I got a container for it, dedicated manager for the custom recipies for it and such, I am not sure which code would give you the correct information so do tell what would help you get an idea and I'll gladly post it, as it is a bit much of code I don't post it all right now.

I did, it seems to be correlated to what DB07 said which I find odd that Eclipse can run it but the builder fails then, peculiar

Yes good sir

I try to compile the mod for some to test but some of the art does not appear. when I play it in my modding it all appears perfectly fine but when I compile it and run it in normal minecraft it does not, what could cause this? I have it all in \forge\src\main\resources\assets\modID when i do compile it and I can see that the stuff is in there.

I am working on making a lamp running on gas, I got 1 for it being inactive that has no light level, and I got 1 for when it is on with light level. But when it renders I get no light spreading, I have checked it so it says "Light level 15" package aerosteam.blocks; import aerosteam.AeroSteam; import aerosteam.items.ItemsAS; import aerosteam.tileentity.TileEntityFirePlace; import aerosteam.tileentity.TileEntityGasLamp; import cpw.mods.fml.relauncher.Side; import cpw.mods.fml.relauncher.SideOnly; import java.util.Random; import net.minecraft.block.Block; import net.minecraft.block.ITileEntityProvider; import net.minecraft.block.material.Material; import net.minecraft.client.renderer.texture.IIconRegister; import net.minecraft.creativetab.CreativeTabs; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.init.Blocks; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.AxisAlignedBB; import net.minecraft.util.MovingObjectPosition; import net.minecraft.util.Vec3; import net.minecraft.world.World; import static net.minecraftforge.common.util.ForgeDirection.*; public class DeviceGasLamp extends Block implements ITileEntityProvider { private static final String __OBFID = "CL_00000325"; public boolean isActive; private static boolean keepInventory; public DeviceGasLamp(boolean active) { super(Material.circuits); this.setTickRandomly(true); System.out.println("state is: " + active); if (active){ this.setLightLevel(1F); System.out.println("light1"); } if (!active){ this.setCreativeTab(AeroSteam.aeroTab); }else{ this.setLightLevel(1F); this.setCreativeTab(AeroSteam.aeroTab); System.out.println("light2"); } this.isActive=active; System.out.println("light at: " + this.getLightValue()); } public boolean isOpaqueCube() { return false; } /** * If this block doesn't render as an ordinary block it will return False (examples: signs, buttons, stairs, etc) */ public boolean renderAsNormalBlock() { return false; } public void ChangeState(World world, int x, int y, int z, boolean state){ int i=world.getBlockMetadata(x, y, z); if (!world.isRemote) System.out.println("Gas lamp changed state to " + state); TileEntity entity = world.getTileEntity(x, y, z); keepInventory=true; if(state){ world.setBlock(x,y,z,BlocksAS.deviceGasLampactive); }else{ world.setBlock(x,y,z,BlocksAS.deviceGasLampidle); } keepInventory=false; world.setBlockMetadataWithNotify(x, y, z, i, 3); if(entity != null){ entity.validate(); world.setTileEntity(x, y, z, entity); } } /** * The type of render function that is called for this block */ public int getRenderType() { return -2; } public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int side, float hitX, float hitY, float hitZ){ if (player.getHeldItem() != null){ if (player.getHeldItem().getItem() == ItemsAS.toolWrench){ if (!world.isRemote) System.out.println("light measurement: " + this.getLightValue()); } } return true; } @Override public TileEntity createNewTileEntity(World p_149915_1_, int p_149915_2_) { return new TileEntityGasLamp(); } @SideOnly(Side.CLIENT) public void registerBlockIcons(IIconRegister iconregister){ this.blockIcon = iconregister.registerIcon(AeroSteam.MODID + ":" + "GasLamp"); } @SideOnly(Side.CLIENT) public void randomDisplayTick(World p_149734_1_, int p_149734_2_, int p_149734_3_, int p_149734_4_, Random p_149734_5_) { if (this.isActive){ double d0 = (double)((float)p_149734_2_ + 0.5F); double d1 = (double)((float)p_149734_3_ + 0.7F); double d2 = (double)((float)p_149734_4_ + 0.5F); double d3 = 0.2199999988079071D; double d4 = 0.27000001072883606D; p_149734_1_.spawnParticle("smoke", d0, d1, d2+0.1F, 0.0D, 0.0D, 0.0D); p_149734_1_.spawnParticle("smoke", d0, d1, d2, 0.0D, 0.0D, 0.0D); p_149734_1_.spawnParticle("flame", d0, d1, d2, 0.0D, 0.0D, 0.0D); p_149734_1_.spawnParticle("flame", d0, d1-0.15F, d2, 0.0D, 0.0D, 0.0D); } } }

I am working on my gun still and the bullet, which moves REALLY slow for exploration purposes, is having dead angles where it is not being rendered, if I move about or change my looking angle ever so slightly it will reappear where it would be after having moved and all, what could cause this? package aerosteam.renderer.mob; import org.lwjgl.opengl.GL11; import aerosteam.AeroSteam; import aerosteam.mobs.MobThief; import aerosteam.model.mobs.ModelBullet; import aerosteam.model.mobs.ModelThief; import aerosteam.projectiles.ProjectileBullet; import net.minecraft.client.model.ModelBase; import net.minecraft.client.renderer.entity.Render; import net.minecraft.client.renderer.entity.RenderLiving; import net.minecraft.entity.Entity; import net.minecraft.entity.EntityLiving; import net.minecraft.util.ResourceLocation; public class RenderBullet extends Render { private static final ResourceLocation texture = new ResourceLocation(AeroSteam.MODID + ":" + "textures/model/Bullet.png"); protected ModelBullet modelEntity; public RenderBullet(ModelBase model, float f) { modelEntity=((ModelBullet) model); } public void doRender(Entity entity, double x, double y, double z, float u, float v){ GL11.glPushMatrix(); GL11.glTranslatef((float)x,(float)y,(float)z); GL11.glRotatef(180, 0F, 0F, 1F); this.bindTexture(texture); GL11.glPushMatrix(); this.modelEntity.renderModel(0.0625F); GL11.glPopMatrix(); GL11.glPopMatrix(); } @Override protected ResourceLocation getEntityTexture(Entity p_110775_1_) { return texture; } } this is the code I have PS: I am noticing that the server position of the object and client positoin differ by the eyeheight of the player, could that affect it?

Client side was the issue, thanks. I really gotta learn how those things work.

Hiya, I am trying to make a gun, or a musket more. I am currently messign around and I have encountered a strange problem. The bullet does not appear, I have other items that spawns it and even detects it where I shot the gun (as I haven't added movement yet) but it is not visible this is the spawning code I have in the musket, where it does not appear, I DO get the message that a bullet has been fired (and hear the sound) public void onPlayerStoppedUsing(ItemStack stack, World world, EntityPlayer player, int i) { if (!world.isRemote){ if (needReload){ this.reloading=false; int j = this.getMaxItemUseDuration(stack) - i; }else{ double x = player.posX; double y = player.posY+player.eyeHeight; double z = player.posZ; world.playSoundEffect(x, y, z, "random.explode", 3.0F, 1.0F / (0.7F)); ProjectileBullet bullet = new ProjectileBullet(world); bullet.setPosition(player.posX, player.posY, player.posZ); world.spawnEntityInWorld(bullet); System.out.println("bullet at-" + bullet.posX + "," + bullet.posY + "," + bullet.posZ); } System.out.println("stopped-" + this.needReload); this.needReload=!this.needReload; } } This is my "wrench" which I use for various tasks as I need it, it locates the bullet that was recently spawned AND spawns another one, when THIS item spawns a bullet it appears visible. public ItemStack onItemRightClick(ItemStack stack, World world, EntityPlayer player) { System.out.println("Item Right Click"); List near = world.getLoadedEntityList(); for (int i = 0; i < near.size(); ++i) { Entity entity = (Entity)near.get(i); if (entity instanceof ProjectileBullet){ System.out.println("There's a bullet!: " + entity.posX + ":"+ entity.posY + ":" + entity.posZ); } } /*if (world.getBlock(x, y, z) instanceof Gases){ System.out.println("Gas Meta: " + world.getBlockMetadata(x, y, z)); System.out.println("X Y Z: " + x + ";" + y + ";" + z); }*/ ProjectileBullet bullet = new ProjectileBullet(world); bullet.setPosition( player.posX, player.posY, player.posZ); world.spawnEntityInWorld(bullet); return stack; } What could be the culprit?

I am interested in, in my rendering, to store some additional data in a chunk, like "Does it have X?" which would be a boolean for the entire chunk, this is so I can make occurences not happen all too close to one another as I want some distance between them, how would I go about it exacly? I don't want the code for me, just either a tutorial (as I don't know what to search for) or hints on what kind of structures would allow it, if I get something simple that gives me a signal of some sort I love to explore the rest myself!

any good tutorial or explonation of it?

IN this mod you see the tornado pick up blocks and move them about, I am curious what is the function that renders some entity you can control from a block?

I may add that when I tyr putting some code in the MobThief class which si the entitymob extended one Vec3 targetVec = Vec3.createVectorHelper(this.posX - this.lastTarget.posX, this.boundingBox.minY + (double)(this.height / 2.0F) - (this.lastTarget.posY + (double)this.lastTarget.getEyeHeight()), this.posZ - this.lastTarget.posZ); double xPosition = this.posX+20*Math.signum(targetVec.xCoord); double yPosition = this.posY+20*Math.signum(targetVec.yCoord); double zPosition = this.posZ+20*Math.signum(targetVec.zCoord); System.out.println("New X: " + xPosition); System.out.println("New Y: " + yPosition); System.out.println("New Z: " + zPosition); System.out.println("Move: " + this.getNavigator().tryMoveToXYZ(xPosition, yPosition, zPosition, 5)); this.getNavigator().tryMoveToXYZ(xPosition, yPosition, zPosition, 50); this code, it seems to get the target but the mob never runs toward it, how come?

so.....priorty isn't first second third order but rather higher number = greater priority....dagnamnit I am extending entitymob What I am trying to create is a mob that spawns randomly throughout the day, runs up to a player if they are not seen and then away if they are seen, once they hit the player they grab one of the players tiems and runs off with it

This is the code I use to check it public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int side, float hitX, float hitY, float hitZ){ if (!world.isRemote){ System.out.println("Light value: " + world.getBlockLightValue(x, y, z)); System.out.println("Light_do true value: " + world.getBlockLightValue_do(x, y, z, true)); System.out.println("Light_do false value: " + world.getBlockLightValue_do(x, y, z, false)); System.out.println("saved light block: " + world.getSavedLightValue(EnumSkyBlock.Block, x, y, z)); System.out.println("saved light sky: " + world.getSavedLightValue(EnumSkyBlock.Sky, x, y, z)); } return true; } This is what I get

Both of them give me value 0 in broad daylight

I am interested in doing a gas for my mod (among other things) that is light sensitive and reaction depends on the light level itself, is there a means to which I can detect how much light it recieves? or any proximal block suffices

My explosive one doesn't have it but that seems to have solved the problem Thanks again!

I have encountered a strange phenomena, I have included a video of it. I have an explosive block I can use that detonates when destroyed, no issue there. But I have also created coal dust that explodes upon ignition but it seems that afterward sometimes it is having a block there but it isn't visible and it is fighting with itself as I lag and when I place ANY block there it turns into a stone/ore block, what could cause it? package aerosteam.gases;

Hello! I am working on my little gases and stuff and I wish to add a function to vanilla blocks. Namely that something is produced when they break. Is there a way to do that or is the easiest way to simply replace them? This is somethign that occures naturally (mainly coal block for now)
