Posted September 29, 201311 yr I'm currently trying to make my custom sapling grow into my custom tree. I copied over the files from the vanilla sapling class, but I'm not sure how to get around the biome specific tree growth. When I use bone meal on my sapling, it changes into a regular oak tree. Any help would be appreciated! Custom Sapling public class SilverSapling extends BlockFlower { public static final String[] WOOD_TYPES = new String[] {"Silver"}; private static final String[] field_94370_b = new String[] {"SilverSapling"}; protected SilverSapling(int par1, int par2) { super(par1); float f = 0.4F; this.setBlockBounds(0.5F - f, 0.0F, 0.5F - f, 0.5F + f, f * 2.0F, 0.5F + f); this.setCreativeTab(CreativeTabs.tabDecorations); } /** * Determines the damage on the item the block drops. Used in cloth and wood. */ public int damageDropped(int par1){ return par1 & 3; } public String getTextureFile(){ return "/blocks/SilverSapling.png"; } /** * Ticks the block if it's been scheduled */ public void updateTick(World par1World, int par2, int par3, int par4, Random par5Random) { if (!par1World.isRemote) { super.updateTick(par1World, par2, par3, par4, par5Random); if (par1World.getBlockLightValue(par2, par3 + 1, par4) >= 9 && par5Random.nextInt(7) == 0) { this.markOrGrowMarked(par1World, par2, par3, par4, par5Random); } } } public void markOrGrowMarked(World par1World, int par2, int par3, int par4, Random par5Random) { int l = par1World.getBlockMetadata(par2, par3, par4); if ((l & == 0) { par1World.setBlockMetadataWithNotify(par2, par3, par4, l | 8, 4); } else { this.growTree(par1World, par2, par3, par4, par5Random); } } /** * Attempts to grow a sapling into a tree */ public void growTree(World par1World, int par2, int par3, int par4, Random par5Random) { if (!TerrainGen.saplingGrowTree(par1World, par5Random, par2, par3, par4)) return; int l = par1World.getBlockMetadata(par2, par3, par4) & 3; Object object = null; int i1 = 0; int j1 = 0; boolean flag = false; if (l == 1) { object = new WorldGenTaiga2(true); } else if (l == 2) { object = new WorldGenForest(true); } else if (l == 3) { for (i1 = 0; i1 >= -1; --i1) { for (j1 = 0; j1 >= -1; --j1) { if (this.isSameSapling(par1World, par2 + i1, par3, par4 + j1, 3) && this.isSameSapling(par1World, par2 + i1 + 1, par3, par4 + j1, 3) && this.isSameSapling(par1World, par2 + i1, par3, par4 + j1 + 1, 3) && this.isSameSapling(par1World, par2 + i1 + 1, par3, par4 + j1 + 1, 3)) { object = new WorldGenHugeTrees(true, 10 + par5Random.nextInt(20), 3, 3); flag = true; break; } } if (object != null) { break; } } if (object == null) { j1 = 0; i1 = 0; object = new WorldGenTrees(true, 4 + par5Random.nextInt(7), 3, 3, false); } } else { object = new WorldGenCustomTree(true); if (par5Random.nextInt(10) == 0) { object = new WorldGenCustomTree(true); } } if (flag) { par1World.setBlock(par2 + i1, par3, par4 + j1, 0, 0, 4); par1World.setBlock(par2 + i1 + 1, par3, par4 + j1, 0, 0, 4); par1World.setBlock(par2 + i1, par3, par4 + j1 + 1, 0, 0, 4); par1World.setBlock(par2 + i1 + 1, par3, par4 + j1 + 1, 0, 0, 4); } else { par1World.setBlock(par2, par3, par4, 0, 0, 4); } if (!((WorldGenerator)object).generate(par1World, par5Random, par2 + i1, par3, par4 + j1)) { /*if (flag) { par1World.setBlock(par2 + i1, par3, par4 + j1, this.blockID, l, 4); par1World.setBlock(par2 + i1 + 1, par3, par4 + j1, this.blockID, l, 4); par1World.setBlock(par2 + i1, par3, par4 + j1 + 1, this.blockID, l, 4); par1World.setBlock(par2 + i1 + 1, par3, par4 + j1 + 1, this.blockID, l, 4); else*/ { par1World.setBlock(par2, par3, par4, this.blockID, l, 4); } } } /** * Determines if the same sapling is present at the given location. */ public boolean isSameSapling(World par1World, int par2, int par3, int par4, int par5) { return par1World.getBlockId(par2, par3, par4) == this.blockID && (par1World.getBlockMetadata(par2, par3, par4) & 3) == par5; } } Here is the new code that actually works: public class SilverSapling extends BlockFlower { public static final String[] WOOD_TYPES = new String[] {"Silver"}; private static final String[] Sapling = new String[] {"SilverSapling"}; private Icon[] SilverSaplingIcon; protected SilverSapling(int par1, int par2) { super(par1); float f = 0.4F; this.setBlockBounds(0.5F - f, 0.0F, 0.5F - f, 0.5F + f, f * 2.0F, 0.5F + f); this.setCreativeTab(CreativeTabs.tabDecorations); } /** * Determines the damage on the item the block drops.

September 29, 201311 yr Don't call super.updateTick(). You don't want the superclass to be growing things on top of you. getBlockMetaData() probably does not behave as you would expect. If you are expecting a certain value, it will probably not be there. (it has never worked for me) Odds are good I've been programming since before you were born. Yeah. I'm OLD school.
September 30, 201311 yr Author Alright, I extended the BlockSapling class, but now my saplings appear as regular oak saplings that grow into my custom tree. So I need to make the class choose my custom texture. Also, if anyone has any input on how I can clean up this code to get rid of the parts I don't need I would appreciate it.
September 30, 201311 yr Well basically, remove everything. Then add whatever changes you want to do. Texture(s) for example.
October 1, 201311 yr Author Yay! I got it to work! Thanks GoToLink for the help! The tip on extending BlockSapling helped tremendously! I was able to figure it out after that by commenting out all the different parts until I better understood what each part did. I will post the code now for anyone who is curious about making their own. public class SilverSapling extends BlockFlower { public static final String[] WOOD_TYPES = new String[] {"Silver"}; private static final String[] Sapling = new String[] {"SilverSapling"}; private Icon[] SilverSaplingIcon; protected SilverSapling(int par1, int par2) { super(par1); float f = 0.4F; this.setBlockBounds(0.5F - f, 0.0F, 0.5F - f, 0.5F + f, f * 2.0F, 0.5F + f); this.setCreativeTab(CreativeTabs.tabDecorations); } /** * Determines the damage on the item the block drops. Used in cloth and wood. */ public int damageDropped(int par1){ return par1 & 3; } public String getTextureFile(){ return "/blocks/SilverSapling.png"; } /** * Ticks the block if it's been scheduled */ public void updateTick(World par1World, int par2, int par3, int par4, Random par5Random) { if (!par1World.isRemote) { super.updateTick(par1World, par2, par3, par4, par5Random); if (par1World.getBlockLightValue(par2, par3 + 1, par4) >= 9 && par5Random.nextInt(7) == 0) { this.markOrGrowMarked(par1World, par2, par3, par4, par5Random); } } } public void markOrGrowMarked(World par1World, int par2, int par3, int par4, Random par5Random) { int l = par1World.getBlockMetadata(par2, par3, par4); if ((l & == 0) { par1World.setBlockMetadataWithNotify(par2, par3, par4, l | 8, 4); } else { this.growTree(par1World, par2, par3, par4, par5Random); } } /** * Attempts to grow a sapling into a tree */ public void growTree(World par1World, int par2, int par3, int par4, Random par5Random) { if (!TerrainGen.saplingGrowTree(par1World, par5Random, par2, par3, par4)) return; int l = par1World.getBlockMetadata(par2, par3, par4) & 3; Object object = null; int i1 = 0; int j1 = 0; boolean flag = false; object = new WorldGenCustomTree(true); par1World.setBlock(par2, par3, par4, 0, 0, 4); if (!((WorldGenerator)object).generate(par1World, par5Random, par2 + i1, par3, par4 + j1)) { par1World.setBlock(par2, par3, par4, this.blockID, l, 4); } } //} /** * Determines if the same sapling is present at the given location. */ public boolean isSameSapling(World par1World, int par2, int par3, int par4, int par5) { return par1World.getBlockId(par2, par3, par4) == this.blockID && (par1World.getBlockMetadata(par2, par3, par4) & 3) == par5; } }
