JSCoord
JSCoord is a simple coordinate and map system for JS. It provides a simple API for manipulating coordinates and setting maps(limits).
JSCoord's Website. Also contains documentation :)
Basic Usage
Install JSCoord using NPM:
npm i jscoord --save
Once its installed, you can import it into your application by adding this to the top of the script:
const { JSCoord } = require("jscoord")
Or if you use Typescript/Webpack:
import JSCoord from "jscoord";
Then, to create a new JSCoord
instance, use:
let coords = new JSCoord(x, y, z)
And there you have it! coords
will be a new JSCoords instance. You can now mutate it using the provided methods.
Properties
.x
, .y
, .z
Get X, Y or Z value. Do NOT modify these variables, they can break your coordinate set.
coords.x
Methods
JSCoord provides some basic mutation methods. They can be used to modify the coordinate set in different ways.
.incrX(amount)
, .incrY(amount)
, .incrZ(amount)
Increments the specified axis by amount
. If amount
parameter is not provided, increments by 1.
coords.incrX(10)
.decrX(amount)
, .decrY(amount)
, .decrZ(amount)
Decrements the specified axis by amount
. If amount
parameter is not provided, decrements by 1.
coords.decrX(10)
.setX(val)
, .setY(val)
, .setZ(val)
Sets the axis value to val
.
coords.setX(20)
.invX()
, .invY()
, .invZ()
"Inverts" the number, so it becomes its negative/positive version. 3 becomes -3, -3 becomes 3 and so on.
coords.invX()
.setMap(x, y, z)
Sets the maximum range for each axis. It sets the maximum to the provided number and the minimum to the negative of the provided number. Other methods will fail if they are out of range. This will fail if axis is above limit already.
coords.setMap(100, 100, 100)
.mapJSON
Get Map as Object.
coords.mapJSON // {x: 20, y: 0, z: 0}
.mapArray
Get Map as Array.
coords.mapArray // [x, y, z]
.JSON
Returns the X, Y and Z axis values as an object.
coords.JSON // {x: 20, y: 0, z: 0}
.array
Returns the X, Y and Z axis values as an array. .array[0]
contains the X axis, .array[1]
the Y axis and .array[2]
the Z axis.
coords.array // [x, y, z]
.reset()
Resets all of the X, Y and Z values to 0.
coords.reset()
.rlt(x, y, z)
Set the relativity of the current coordinates from the provided coordinate set perpective.
coords.rlt(10, 20, 30)
.rltJSON
Get the relativity set as an object.
coords.rltJSON // {x: 1, y: 2, z: 3}
.rltArray
Get the relativity set as an array.
coords.rltArray // [x, y, z]
.getRltAngle(set)
Get the angle of 2 coordinate set values. set
is the 2 axies which should be used for calculation, can be xy
, yz
or zx
.
coords.getRltAngle("xy")
CoordChunk
CoordChunk is another feature of JSCoord. Its basically an Array of Sets with some extra functions. When creating a CoordChunk instance, you can pass a parameter to set the maximum size of the set.
const { CoordChunk } = require("jscoord")
Or if you use Typescript/Webpack:
import { CoordChunk } from "jscoord";
Then, to create a new instance:
let chunk = new CoordChunk(10)
Properties
.limit
Maximum length of chunk. Do NOT modify this variable, it can break your coordinate set.
chunk.limit
.sets
Array in which Sets are stored. Do NOT modify this variable, it can break your coordinate set.
chunk.sets
Methods
.addSet(coords)
Add a Set to the Chunk. coords
can be an Array with coordinate values ([x, y, z])
or a JSCoord instance. You can not have 2 of the same coordinate sets in the same chunk.
chunk.addSet(new JSCoord(100, 100, 100))
.getSet(coords)
Find a Set by coordinates. Throws if Set could not be found.
chunk.getSet([100, 100, 100])
.delSet(coords)
Delete a Set from the Chunk. coords
can be an Array with coordinate values or a JSCoord instance. Throws if Set could not be found.
chunk.delSet([100, 100, 100])
