Library to work with Free Rider HD Tracks

Project Description

A Python library for working with Free Rider HD Tracks.

Introduction

Free Rider HD is an online HTML5 + JS game where users can draw bike tracks, upload them to a community of players, and ride them. (Go try it out!)

When drawing a track, you can import track code from a file or from your clipboard. This library (as of now) allows you to generate that code.

Install

Fire up a terminal and run:

pip install frhdtools

You should be good to go.

Usage

Example 1: Straight Line

When you start, you’ll want to import frhdtools:

import frhdtools

Next, you should create a Track class. This will hold all of your track’s objects and code.

my_track = frhdtools.Track.Track()

Now that you’ve done that, you can add a line:

my_track.insLine(-40,50,100,50,'p')

This line goes from (-40,50) to (100,50). What is the ‘p’, you ask? That corresponds to the type of line. In this case, it means a physics line. More on types of lines later.

Now, lets generate our code:

print(my_track.genCode())
This will generate the code stored in my_track and print it to stdout.
In my case, the code was this:
-18 1i 34 1i,###

Don’t worry what the code means just yet. First let’s plug it into FRHD to see if it works.

In the Track Editor, click “Import” at the top of the editor:

Then paste in your generated code at the window that pops up.

After it loads your file, the track should look exactly like this:

Wondering about the helmet? It’s just swag.

Congratulations! You’ve just finished you first line segment. It will get easier, I promise. :wink:

Example 2: Scenery Line

Remember how I mentioned that there were different types of lines? Well here’s what they are.

In the last example we used a physics line. The rider can interact and ride on those.

In this example you’ll make a scenery line. A scenery line is a line that the rider cannot ride on. It is purely just for scenery. Also, scenery lines are gray instead of black.

It’s really easy to make a scenery line. Instead of using the code from last time:

import frhdtools
my_track = frhdtools.Track.Track()
my_track.insLine(-40,50,100,50,'p')
print(my_track.genCode())

We change the ‘p’ to an ‘s’ in my_track.insLine:

import frhdtools
my_track = frhdtools.Track.Track()
my_track.insLine(-40,50,100,50,'s')
print(my_track.genCode())

(FYI: The code should be #-18 1i 34 1i,##)

Now, when you plug the code into FRHD, you will get this:

Note: the rider will fall through the line as it does not have physics. This is normal.

Now you have made a scenery line. Great!

Example 3: Boost

In this example, you will learn how to make a boost powerup.

To start, let’s take our code from the first example:

import frhdtools
my_track = frhdtools.Track.Track()
my_track.insLine(-40,50,100,50,'p')
print(my_track.genCode())

and add my_track.insBoost(90,-10,90)

import frhdtools
my_track = frhdtools.Track.Track()
my_track.insLine(-40,50,100,50,'p')
my_track.insBoost(90,10,90)
print(my_track.genCode())

This will spawn a boost powerup at (90,10). It will be rotated 90 degrees.

** By the way, the code should look like this: -18 1i 34 1i,##B 2q a 2q,#

Plug that into FRHD, and you’re left with this:

Example 4: Bomb

In this example, you’ll learn how to spawn a bomb powerup. Bombs explode when you touch them.

So, to get started we’ll take our code from our first example and add my_track.insBomb():

import frhdtools
my_track = frhdtools.Track.Track()
my_track.insLine(-40,50,100,50,'p')
my_track.insBomb(90,10)
print(my_track.genCode())

That code makes a bomb at (90,10), which are the same coordinates from the last example.

Go ahead and put that into FRHD:

Example 5: Gravity

In this example, you’ll put a gravity powerup into a track.

Gravity powerups are pretty cool because they can switch gravity. Wow.

You know the drill. Let’s take the code from Example 1 and this time add my_track.insGravity():

import frhdtools
my_track = frhdtools.Track.Track()
my_track.insLine(-40,50,100,50,'p')
my_track.insGravity(90,10,90)
print(my_track.genCode())

Now, when you put that into FRHD, you’ll see something cool:

Honestly, I think that this is one of the coolest features in FRHD; I really apprieciate that the developers took time to put it there.
