rsc-path-finder
在 runescape 经典地图上的点之间生成路径。 每个瓷砖是 扩展为一个 2x2 的布尔值网格,描述了瓷砖是如何被阻挡的。 这 允许水平、垂直和完全阻塞的图块表示 (对角墙完全无法通过)。 一旦找到路径,步骤就是 平滑并转换为游戏坐标。
由于计算是异步的,因此可以安全地在游戏循环中使用该模块。
从 Lumbridge 到 Legend's Guild 的路径
从 Al Kharid 到 Bandit Camp 的路径
Tree Gnome Village 入口的路径

api
pathFinder = new PathFinder(config, landscape, tickRate = 80)
创建一个新的寻路实例。
config
第一个参数必须包含 game 和 wall 对象的定义 至少包含以下内容:
{
// definitions for game objects (tree, altar, furnace, etc.)
objects: [
{
type: 'unblocked' || 'blocked || 'closed-door' || 'open-door',
width: Number,
height: Number
},
// ...
],
// definitions for wall objects (doors, walls, boundaries, etc.)
wallObjects: [
{
blocked: true || false,
}
// ...
]
// definitions for tiles (floors, water, roads, etc.)
tiles: [
{
blocked: true || false,
}
// ...
]
}
对象, wallObjects 和 瓷砖 都是一个成员 rsc-config 实例。
landscape
是一个实例 rsc-landscape。
tickRate
是在 findPath
时轮询新路径的频率(以毫秒为单位) 不活跃。
pathFinder.addObject({ id, x, y, direction })
将游戏对象添加到位置。 id
对应于 config.objects
中的索引。 如果 添加了open-door
或closed-door
类型对象,将它们替换为 door 墙对象。
pathFinder.addWallObject({ id, x, y, direction })
将墙对象添加到位置。 id
对应于 config.wallObjects
中的索引 大批。 如果添加了未阻挡的墙对象,请移除所有现有障碍物 (带门框的门、带空白的蜘蛛网等)。
pathFinder.start()
pathFinder.stop()
启用和禁用寻路运行循环。
async pathFinder.findPath({ x, y }, { x, y })
找到 startPos 和 endPos 之间的路径。 返回游戏坐标数组。
pathFinder.isValidGameStep({ x, y }, { deltaX, deltaY })
如果我们可以在步进方向上从 startPos 步进,则返回 true。
pathFinder.getLineOfSight({ x, y }, { x, y })
找到两点之间的直接对角线直线路径。
pathFinder.toCanvas(path = undefined)
创建一个画布,所有障碍物都用白色填充。 如果路径是 指定,用红色填充路径图块。

rsc-path-finder
generate paths between points on a runescape classic map. each tile is expanded into a 2x2 grid of booleans describing how the tile is blocked. this allows for horizontal, vertical and fully-blocked tile representation (diagonal walls are completely impassbale). once a path is found, the steps are smoothed and converted to game coordinates.
this module is safe to use in a game loop as the computation is asynchronous.
path from Lumbridge to the Legend's Guild
path from Al Kharid to Bandit Camp
path to Tree Gnome Village entrance

api
pathFinder = new PathFinder(config, landscape, tickRate = 80)
create a new pathfinding instance.
config
in the first argument must contain definitions of game and wall objects with at least the following:
{
// definitions for game objects (tree, altar, furnace, etc.)
objects: [
{
type: 'unblocked' || 'blocked || 'closed-door' || 'open-door',
width: Number,
height: Number
},
// ...
],
// definitions for wall objects (doors, walls, boundaries, etc.)
wallObjects: [
{
blocked: true || false,
}
// ...
]
// definitions for tiles (floors, water, roads, etc.)
tiles: [
{
blocked: true || false,
}
// ...
]
}
objects, wallObjects and tiles are all members of an rsc-config instance.
landscape
is an instance of rsc-landscape.
tickRate
is how often (in ms) to poll for new paths to find when findPath
isn't active.
pathFinder.addObject({ id, x, y, direction })
add game object to position. id
corresponds to index in config.objects
. if open-door
or closed-door
type objects are added, replace them with door wall objects.
pathFinder.addWallObject({ id, x, y, direction })
add wall object to position. id
corresponds to index in config.wallObjects
array. if an unblocked wall object is added, remove any existing obstacles (door with doorframes, spider web with blank, etc.).
pathFinder.start()
pathFinder.stop()
enable and disable the pathfinding run loop.
async pathFinder.findPath({ x, y }, { x, y })
find a path between startPos and endPos. returns an array of game coordinates.
pathFinder.isValidGameStep({ x, y }, { deltaX, deltaY })
return true if we can step from startPos in the step direction.
pathFinder.getLineOfSight({ x, y }, { x, y })
find a direct diagonal beeline path between two points.
pathFinder.toCanvas(path = undefined)
create a canvas with all of the obstacles filled in with white. if path is specified, fill the path tiles with red.
