I want to add condition in constructor for angle if(angle>360){ angle=0; } how to do?
PLAYER[i] = {
color: "#fff",
x: 220*i,
y: 270,
width: 32,
height: 32,
angle: 180
};
each time to use such a condition, takes a lot of space.

This isn't a constructor -- just initialization of an object. But nevermind that. Use the ternary operator: angle: (angle > 360 ? 0 : angle)

So i want to loop through it and have to return total value i.e '300px'
Can someone please help me?

sumWidth+= parseInt(object.width.slice(0,-2))

Hi I was wondering how do you write this in an if() statment in java?
"If either polonium dips below 0.75, spider_venom goes above 0.52, or perhaps sarin dips below 0.66, increase paracetamol by 0.01"
I wrote this but it is wrong.
if((polonium < 0.75 && spider_venom > 0.52) || (sarin < 0.66))
{
paracetamol += 0.01
}
This should work:
if(polonium < 0.75 || spider_venom > 0.52 || sarin < 0.66)
{
paracetamol += 0.01
}
The reason your code is incorrect, is that you have an AND in the condition statement. Your conditions could be translated as, IF any of those three conditions hold, THEN do increase paracetamol by 0.01, which is just OR-ing all three statements.

I was developing this polilynes code, and I need to display the polilyne distance completely, how do I do this?
Here below is the code I am using:

You can calculates geojson with libs like Turf.js.
For example, turf/length measures length of lineString, like below.
const line = turf.lineString([
[-53.08074, -25.766767],
[-53.097358, -25.77123],
[-53.117901, -25.798796],
[-53.147227, -25.801503],
[-53.187904, -25.812659],
[-53.235429, -25.811208],
[-53.276227, -25.802679],
[-53.305865, -25.788242]
]);
const len = turf.length(line, { units: "kilometers" }); // 24.96224597809012

I want to use only one color with the library trianglify.min.js
The library use colors random.
trianglify library in Options x_colors, default is 'random'. Specify the color gradient used on the x axis.
Valid array values should specify the color stops in any CSS format (i.e. ['#000000', '#4CAFE8', '#FFFFFF']).
var pattern = Trianglify({
cell_size: 75,
variance: 0.75,
x_colors: ['#fff','#28345A'],
y_colors: 'match_x',
palette: Trianglify.colorbrewer,
color_space: 'rgb',
color_function: false,
stroke_width: 1.51,
width: window.innerWidth-5,
height: window.innerHeight-5,
seed: 'd4hga',
stroke_width: 1.51,
color_function: null
});
document.body.appendChild(pattern.canvas())

I need to create a graph with a dynamic number of vertices, which will look like this
enter image description here
Which layout is best used to get vertical vertices?
Force directed graph might be a solution to your problem. Here are a few options:
https://zoomcharts.com/en/chart-types-demo/graph-chart-using-netchart
https://bl.ocks.org/mbostock/4062045
http://visjs.org/examples/network/basicUsage.html
If you want to have the layout going explicitly in vertical way, you might need to consider either hierarchical or fixed layout like here:
http://jsfiddle.net/L9m34ev5/1/
var t = new NetChart({
container: document.getElementById("demo"),
area: { height: null },
navigation:{
focusNodeExpansionRadius: 2,
initialNodes: ["syslog"],
mode:"focusnodes"
},
style:{
node:{display:"image",lineWidth:2, lineColor: "red", imageCropping: true},
nodeStyleFunction: function(node){node.radius = 50;}
},
data: { url:"https://zoomcharts.com/dvsl/data/net-chart/bubbles.json" },
layout:{
mode:"hierarchy",
nodeSpacing: 45, // horizontal spacing between nodes
rowSpacing: 80, // vertical spacing between node rows in the hierarchy layout
rotation: 90
}
});
