Tilemap模块
脚本入口: eve.Map()
创建或载入 TileLayer,设置瓦片、投影、图层并提交渲染;可用 Pathfinder 做格子寻路与群体 Flow Field,用 Fov 做动态视野与探索记忆。
基本用法
local map = eve.Map();
local layer = map.newLayerFromFile("maps/level.json");
layer.setTile(2, 3, 7);
map.update(dt);
map.render(gfx);
对象关系与调用时机
Map 聚合 TileLayer 并统一更新/渲染;TileLayer 保存网格、投影、origin、层级和图集资源。JSON loader 把 Tiled 数据映射到这些对象。寻路在格子索引空间进行,与投影解耦;需要世界坐标时对路径点调用 tileToWorld*。
目标导向指南
载入 Tiled 地图
把 JSON 和图集放在游戏目录,用 newLayerFromFile(path) 创建层;初始化后设置 origin、layer 和 visible。每帧 map.update(dt),渲染时 map.render(gfx)。
运行时修改瓦片
先用地图坐标换算接口把世界位置转成格子,再 setTile(x, y, gid);批量生成地图时先 resize,再填充,避免重复重建图层。0 通常表示空瓦片。改瓦片后若已创建 Pathfinder,调用 syncFromLayer()。
单体寻路(A*)
local pf = map.newPathfinder(layer);
pf.setTopology("auto"); // ortho4 / ortho8 / hex;auto 按 orientation
pf.blockGid(1); // 墙 GID
local path = pf.findPath(sx, sy, gx, gy);
if (path.getLength() > 0) {
local x = path.getX(0);
local y = path.getY(0);
}
正交/等距默认四向;setDiagonal(true) 后 auto 升为八向。交错/六角地图 auto 为 hex。
群体寻路(同目标 Flow Field)
多单位前往同一格时,建一次势场再各自跟随,避免每人跑一遍 A*:
local field = pf.buildFlowField(gx, gy);
local p1 = pf.followFlow(field, ax, ay);
local p2 = pf.findGroupPath(bx, by, gx, gy); // 内部复用缓存场
local nx = field.nextX(ax, ay);
local ny = field.nextY(ax, ay);
自定义网格(不绑 TileLayer):map.newPathfinderSize(w, h),再用 setBlocked / setCellCost。
动态视野(FOV / 战争迷雾)
格子可见性与探索记忆;遮挡(opaque)与寻路可行走(walkable)分开配置。默认算法为 recursive shadowcasting;可选 raycast / permissive / rectangle。模式:grid2d(默认)、heightmap、volume。拓扑:ortho / hex。
local fov = map.newFov(layer);
fov.setBlockEmpty(false);
fov.blockOpaqueGid(1);
fov.setRadiusMetric("chebyshev");
fov.setTopology("auto"); // 或 "hex"
local id = fov.addRevealer(sx, sy, 8);
// 软 RPG 挂钩:游戏自行读取 actor 属性后写入
fov.setRevealerPerception(id, actor.getFinalAttribute("perception"));
fov.setPerceptionRadiusScale(0.25);
fov.setDetectionMargin(0.0);
fov.compute();
if (fov.canDetect(id, tx, ty, targetStealth)) { /* 可见且感知足够 */ }
local tex = fov.buildMaskTexture(gfx); // RGBA8 FoW 遮罩,调用方拥有
自定义网格:map.newFovSize(w, h) + setOpaque。移动观察者后再次 compute();无变更时 isDirty() 为 false,compute 会跳过。离开视野的格子保留 explored,可用 clearMemory() 清空。
高度场:
fov.setMode("heightmap");
fov.setElevation(4, 1, 2.0);
fov.setCliffBlock(1.0);
体素 3D:
local fov3 = map.newFovVolume(32, 32, 8);
fov3.setOpaque3(4, 4, 2, true);
fov3.addRevealer3(4, 4, 1, 10);
fov3.setVerticalRange(4);
fov3.compute();
fov3.isVisible3(8, 4, 1);
Dual Grid(双网格)
Tiled 没有原生 dual-grid;在编辑器里画逻辑填充层,运行时解算显示层。支持正交 / 等距 / 交错 / 六角:掩码按格子索引采样,显示层继承投影参数并施加对应半步 origin 偏移。
local map = eve.Map();
local logic = map.newLayer(16, 12, 32, 32);
local display = map.newLayer(1, 1, 32, 32);
// display.setTileset(tex, 1, 4); // 4×4 的 15-tile 图集
logic.setTile(3, 4, 1);
map.resolveDualGrid(logic, display); // 半步偏移 + 15 片选瓦
// map.dualGridOffsetX(logic) / dualGridOffsetY(logic) 可查偏移量
resolveDualGridFilled(logic, display, filledGid) 只把指定 GID 当作填充。逻辑层可继续用于碰撞 / 寻路;默认会 setVisible(false)。
常见问题
- GID 与图集编号混淆:0 为空,其余值遵循 tileset 映射;默认空瓦片不可走(
setBlockEmpty)。 - 世界坐标直接作为 tile 索引:先做投影换算。
- 修改 JSON 后未启用 watch/autoReload。
- 期望 Tiled 直接导出 dual-grid 显示层:不支持;用逻辑层 +
resolveDualGrid。 - 寻路失败:
getLength()==0(越界、不可走或不可达),不是抛异常。

使用要点
- 模块对象和它创建的资源对象应保存在全局或实体状态中,不要在每帧重复创建。
- 带
update(dt)的系统应在eve_update调用;绘制方法应在eve_render调用。 - 参数约束、默认值和返回类型以对应模块头文件及
addFunc绑定为准;本文 API 快查与当前源码同步生成。
