Usage
var VisionSimulation = ;var worlddata = ;var options = radius: 1600; var vs = worlddata options;vs;
worlddata
- world dimensions, {"worldMinX":-8288,"worldMaxX":8288,"worldMinY":-8288,"worldMaxY":8288}
options
- Optional settings object.
radius
- Initial radius in grid tiles. Default: 1600 / 64
Methods
initialize(mapImageDataPath, onReadyCallback)
- Starts the vision simulation.
-
mapImageDataPath
- path to map data image, "www/map_data.png" -
onReadyCallback(err)
- callback executed when map data is loaded and vision simulation is ready. Returns an error object if an exception occurred.
updateVisibility(gX, gY, radius)
- Executes the FOV calculation and update the lights
property on the VisionSimulation object. (gX, gY) is a grid coordinate representing a 64x64 tile in the 260x260 world grid. radius optional.
toggleTree(gX, gY)
- Toggles tree cut down state at (gX, gY) in grid coordinates.
setRadius(r)
- Sets default radius.
WorldXYtoGridXY, GridXYtoWorldXY, GridXYtoImageXY, ImageXYtoGridXY, WorldXYtoImageXY
- Functions for converting between world, grid, and image coordinates.
key2pt, xy2key, xy2pt, pt2key
- Functions for converting between (x, y), {x: x, y: y}, and "x,y" coordinate formats.
isValidXY(gX, gY, bCheckGridnav, bCheckToolsNoWards, bCheckTreeState)
- Check whether grid coordinate is a valid position or not. bCheckGridnav, bCheckToolsNoWards, bCheckTreeState optional.
