typed-struct-js

Inplementation of typed structure (es7 like) in JS using typed array and arrayBuffer...

How to use

1//Import the module
2var Struct = require("typed-struct-js");
3
4//Let's define Vector
5
6var Vector = new Struct({
7	x:"Float32",
8	y:"Float32"
9});
10
11//And color too 
12
13var Color = new Struct({
14	red: "Uint8",
15	green: "Uint8",
16	blue: "Uint8"
17});
18
19//Let's get some red;
20
21var red = Color.get();
22red.set("red",255);
23
24//Let's get a random Vector;
25
26var direction = Vector.get();
27direction.set("x",Math.random()*2-1).set("y",Math.random()*2-1);
28console.log("x " + direction.get("x"), "y " + direction.get("y"));
29
30//Let's get deeper
31//Now we define a pixel
32
33var Pixel = new Struct({
34	pos:Vector,
35	color:Color
36});
37
38//And change it a bit
39
40var point = Pixel.get();
41point.get("pos").set("x",10).set("y",25);
42point.get("color").set("green",255);
43
44//Now it's time to use Array for fast access;
45//This is supposed to be THE point of this lib
46
47var triangle = Pixel.Array(3);
48triangle.get(0).get("pos").set("x", 50).set("y", 0);
49triangle.get(1).get("pos").set("x", 0).set("y", 100);
50triangle.get(2).get("pos").set("x", 100).set("y", 100);
51for(var i=0;i<.triangle.length,i++) {
52	triangle.get(i).get("color").set("blue",i*85).set("red",255-i*85);
53}
