FRHD-API - FRHD-Lang replacement

Hello! Today I started working on a new project, the FRHD API. This allows you to generate tracks, by programming with JavaScript.
Link: http://bit.ly/2bAO8zu
Examples:

Code:

for (var x = 0-25; x < 25; x += 5) {
    for (var y = 50; y < 100; y += 5) {
        track.addLine(new Line(x, y, x*y, x*y));
    }
}

creates the track here: https://www.freeriderhd.com/t/297608-introducing-the-free-rider-api/

more coming soon....

 

Another Example
Example of vertical lines (with easily variables), with alternating between scenery and foreground:

Code:

var startX = -40;
var endX = 80;
var spacing = 10;
var topY = 50;
var bottomY = 130;

var scenery = false;
for (var x = startX; x <= endX; x += spacing, scenery = !scenery) {
    track.setMode(scenery ? 1 : 0);
    track.addLine(new Line(x, topY, x, bottomY));
}

here's how for loops work:

the format of the for loop in JS and most languages is for (initializeVariablesHere; loopUntilThisIsTrue; doThisEveryTimeItLoops)

so for example (ha, for. ha.)

for (var i = 0; i < 10; i++)

will run the code inside the braces after it. there is a variable called "i" which can be accessed inside the braces.
so every time it loops, i will equal:
0, then 1, then 2... etc..... then 9. Since after that (10 < 10) is false (10 is not smaller than 10), the loop stops. You could also do

for (var i = 0; i < 10; i += 2)

so this time, instead of i increasing by 1, it increases by two (++ is short for += 1)

so every time it loops, i equals 0, then 2, then 4, then 6, then 8. since 10 < 10 is false, it stops looping

Hope that helps... just ask any more questions if you have some

Code:

var startX = -699245;
var endX = 699245;
var spacing = 490;
var topY = -10000;
var bottomY = 10000;

for (var y = topY; y <= bottomY; y += spacing) {
    track.addLine(new Line(startX, y, endX, y));
}
var startX = -10000;
var endX = 10000;
var spacing = 490;
var topY = -699245;
var bottomY = 699245;

for (var x = startX; x <= endX; x += spacing) {
    track.addLine(new Line(x, topY, x, bottomY));
}

 

KillerMeemStar I like the other one better

 

frhd-lang? that one is simpler, but this one is already an existing program, so ppl who know it can use it right away
also it has many many more features, since it's already a programming language in use

 

Sierpinski Triangle
Hello! If you haven't seen my sierpinski triangle track, here it is: https://www.freeriderhd.com/t/297624-sierpinski-triangle

The code for this is (I translated code from an originally pure JS program):

Code:

var width = 600;
var height = 600;
var size = 500;
var dx = -300, dy = -300;
   
function sierpinski(Ax,Ay,Bx,By,Cx,Cy,d) {
    if(d>0) {
        var pointAx = (Bx + Cx) / 2;
        var pointAy = (By + Cy) / 2;
   
        var pointBx = (Ax + Cx) / 2;
        var pointBy = (Ay + Cy) / 2;
   
        var pointCx = (Ax + Bx) / 2;
        var pointCy = (Ay + By) / 2;
   
        var d2 = d-1;
        sierpinski(Ax,Ay,pointBx,pointBy,pointCx,pointCy,d2);
        sierpinski(pointCx,pointCy,pointAx,pointAy,Bx,By,d2);
        sierpinski(pointBx,pointBy,pointAx,pointAy,Cx,Cy,d2);
    }
    else {
        track.addLine(new Line(Ax + dx, Ay + dy, Bx + dx, By + dy));
        track.addLine(new Line(Bx + dx, By + dy, Cx + dx, Cy + dy));
        track.addLine(new Line(Cx + dx, Cy + dy, Ax + dx, Ay + dy));
    }
}
   
   
var midPointX = width/2;
var midPointY = height/2;

var deep = 6;

var ri = (size/6) * Math.sqrt(3);
var ru = (size/3) * Math.sqrt(3);

var pointAx = midPointX-(size/2);
var pointAy = midPointY+ri;

var pointBx = midPointX+(size/2);
var pointBy = midPointY+ri;

var pointCx = midPointX;
var pointCy = midPointY-ru;

sierpinski(pointAx,pointAy,pointBx,pointBy,pointCx,pointCy,deep);

When you see var deep = 6, that represents how many layers will be rendered.
At the top, width and height are self-explanatory, dx and dy represent the offset (so you can move it around the track)

 

Another fractal
Track: https://www.freeriderhd.com/t/297692-another-fractal
I like to call this a "triangle approximation". Here's the code:

Code:

var x = -40;
var y = 50;
var size = 1600;
var layers = 8;

// left side of triangle
track.addLine(new Line(x, y, x, y + size));
// bottom side
track.addLine(new Line(x, y + size, x + size, y + size));
// hypotenuse
track.addLine(new Line(x + size, y + size, x, y));

drawLayer(x, y + size / 2, 1, layers);

// layer starts at 1 (not 0)
function drawLayer(x, y, layer, maxLayers) {
    if (layer > maxLayers)
        return;
    var powerOfTwo = Math.pow(2, layer);
    var endX = x + size / powerOfTwo;
    var endY = y + size / Math.pow(2, layer);
    track.addLine(new Line(x, y, endX, y));
    track.addLine(new Line(endX, y, endX, endY));
  
    layer++;
    // top side
    drawLayer(x, y - size / Math.pow(2, layer), layer, maxLayers);
    // right side
    drawLayer(x + size / Math.pow(2, layer) * 2, y + size / Math.pow(2, layer), layer, maxLayers);
}

KillerMeemStar why the hell do you have me in your sig saying something I didn't say?

 

memes

 

do u really want me to remove it? it's kind of obvious u didn't say it, since its a bigger font and different font family

 

Uh... you don't have to I was just kinda surprised lol

 

i just went to a random track with a bunch of comments, and a meme popped out

 

Added curves! Thanks to Polygon for help with the math!

Function: track.addBezier(new Point(0,0), new Point(100,-100), new Point(100,0), 10) for example will create a curve starting at (0,0), ending at (100,-100), with the control point (100,0), made up of 10 line segments

 

KillerMeemStar this is really cool. I've made a similar (but outdated) implementation in Python, based off of code I used to write the image to track converter. See https://github.com/illinoisjackson/frhdtools.

 

Thanks!
So you are another person who everyone either really hates or really likes?

 

Yep, I caused quite a controversy last year when I introduced an image to track converter that I had coded as an experiment, to test how I could generate track code. Needless to say, a lot of people liked it but more people didn't; it ended up getting taken down. Sorta sad because most of the comments weren't about the program but about my age

 

What you made was awesome but releasing something like that to the public will introduce idiots that'll exploit it

 

It doesn't work. It brings me to a godaddy thing.
