mouse.isDown uses 1 = left / 2 = right (LÖVE-style, matching docs and voxel-terrain/cardgame examples); button 0 is skipped and always false. examples/building (+ building-3d, building-tilemap) called mousePressed(0) for left-click placement, so placing buildings never fired while ghost preview, palette keys, rotation and right-click removal still worked. Switch the mousePressed helper and left-click call sites to button 1.
Tilemap 建筑放置示例
演示在多样式 tilemap 上放置建筑：
map模块创建等距（或六角）TileLayer，world.bindTileLayer(layer)直接复用其投影world.setTerrainGid(gid, semantic)让地形语义从 tile GID 懒解析（水域/陆地）eve.BuildingFx按定义visual2d生成 2D 精灵，进入统一 2D 队列按脚点 Y 穿插PlacementSession封装放置 / 拆除 / 旋转 / 鬼影校验
