Example 1 with WeightedList

use of net.minecraft.util.WeightedList in project DynamicTrees-BYG by DynamicTreesTeam.

the class BranchSproutsGenFeature method placeSprouts.

private void placeSprouts(int count, GenFeatureConfiguration configuration, IWorld world, BlockPos rootPos) {
    WeightedList<Pair<BlockPos, Direction>> validSpots = new WeightedList<>();
    final FindSidedBlockNode sproutPlacer = new FindSidedBlockNode(validSpots, configuration.get(MIN_RADIUS));
    TreeHelper.startAnalysisFromRoot(world, rootPos, new MapSignal(sproutPlacer));
    if (!validSpots.isEmpty()) {
        for (int i = 0; i < count; i++) {
            Pair<BlockPos, Direction> selection = validSpots.getOne(world.getRandom());
            BlockPos pos = selection.getFirst();
            Block block = configuration.get(SPROUT_BLOCK);
            if (world.getBlockState(pos.below()).getBlock() == block)
                return;
            world.setBlock(pos, block.defaultBlockState().setValue(HorizontalBlock.FACING, selection.getSecond()), 3);
        }
    }
}
