From 1a211b6c46b1f71d42799b2f1dabb1790174b81f Mon Sep 17 00:00:00 2001 From: 12xx12 <44411062+12xx12@users.noreply.github.com> Date: Sat, 19 Sep 2020 18:51:26 +0200 Subject: Changing jungle trees a bit (#4823) * switch range on jungle tree generation and renamed a confusing variable * changed two numbers to match vanilla behaviour * made jungle trees closer to vanilla behaviour - matched variable names to new checkstyle - made branch generation independent from noise at block position * replaced random provider with Noise * implemented changes suggested by peterbell10 * changed the way to determine the size of the leaves on branches Co-authored-by: peterbell10 Co-authored-by: 12xx12 <12xx12100@gmail.com> Co-authored-by: peterbell10 Co-authored-by: Alexander Harkness --- src/Generating/Trees.cpp | 40 ++++++++++++++++++++++++++++------------ 1 file changed, 28 insertions(+), 12 deletions(-) diff --git a/src/Generating/Trees.cpp b/src/Generating/Trees.cpp index cd2748ddd..0d6a40291 100644 --- a/src/Generating/Trees.cpp +++ b/src/Generating/Trees.cpp @@ -6,6 +6,7 @@ #include "Globals.h" #include "Trees.h" #include "../BlockType.h" +#include "../World.h" @@ -58,7 +59,7 @@ static const Vector3d & pickBranchDirection(const cNoise a_Noise, Vector3i a_Blo } }; - size_t index = static_cast(a_Noise.IntNoise3DInt(a_BlockPos.x, a_BlockPos.y + a_Seq, a_BlockPos.z)) % directions.size(); + size_t index = static_cast(a_Noise.IntNoise3DInt(a_BlockPos * a_Seq)) % directions.size(); return directions[index]; } @@ -1266,11 +1267,12 @@ void GetLargeJungleTreeImage(Vector3i a_BlockPos, cNoise & a_Noise, int a_Seq, s {2, 1, 2}, {2, 0, 2}, // East face }; - int Height = 20 + (a_Noise.IntNoise3DInt(a_BlockPos.addedXZ(32 * a_Seq, 32 * a_Seq)) / 11) % 12; + int Height = 10 + ((a_Noise.IntNoise3DInt(a_BlockPos.addedXZ(32 * a_Seq, 32 * a_Seq)) / 11) % 20); // 10 < Height < 29 a_LogBlocks.reserve(static_cast(Height) * 4); a_OtherBlocks.reserve(2 * ARRAYCOUNT(BigO5Jungle) + ARRAYCOUNT(BigO4Jungle) + ARRAYCOUNT(BigO3Jungle) + static_cast(Height) * 4 + 50); + // Generates the main trunk for (int i = 0; i < Height; i++) { a_LogBlocks.push_back(sSetBlock(a_BlockPos.addedY(i), E_BLOCK_LOG, E_META_LOG_JUNGLE)); @@ -1288,7 +1290,6 @@ void GetLargeJungleTreeImage(Vector3i a_BlockPos, cNoise & a_Noise, int a_Seq, s a_OtherBlocks.push_back(sSetBlock(a_BlockPos.addedXZ(VinesTrunk[j].x, VinesTrunk[j].z).addedY(i), E_BLOCK_VINES, VinesTrunk[j].Meta)); } } - int hei = a_BlockPos.y + Height - 2; // Prevent floating trees by placing dirt under them for (int i = 1; i < 5; i++) @@ -1299,26 +1300,41 @@ void GetLargeJungleTreeImage(Vector3i a_BlockPos, cNoise & a_Noise, int a_Seq, s a_OtherBlocks.push_back(sSetBlock(a_BlockPos.addedY(-i).addedXZ(1, 1), E_BLOCK_DIRT, E_META_DIRT_NORMAL)); } - int numBranches = (a_Noise.IntNoise2DInt(a_BlockPos.x * a_Seq, a_BlockPos.z * a_Seq) / 11) % 3 + 1; - int branchStartHeight = 8 + Height % 11; - int branchInterval = (Height - branchStartHeight) / numBranches; - for (int i = branchStartHeight; i < (Height - 6); i += branchInterval) + int NumBranches = std::max( + (a_Noise.IntNoise2DInt(a_BlockPos.x * a_Seq, a_BlockPos.z * a_Seq) / 10) % 4, // The Original Calculation + FloorC(Height / 10.0f) // Just to assure that no massive trees spawn with just one branch + ); + int BranchStartHeight = 6 + Height % 5; // 6 < BranchStartHeight < 10 + int BranchInterval = (Height - 6 - BranchStartHeight) / NumBranches; + for (int i = BranchStartHeight; i < (Height - 6); i += BranchInterval) // Stop 6 blocks before reaching the top { // Get a direction for the trunk to go to.
