frhdtools
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
Lines
Example 1: Physics Line
When you start, youâll want to import frhdtools:
import frhdtools
Next, you should create a Track class. This will hold all of your trackâs objects and code.
my_track = frhdtools.Track.Track()
Now that youâve 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 âpâ, 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())
my_track
and print it to
stdout.-18 1i 34 1i,###
Donât worry what the code means just yet. First letâs plug it into FRHD to see if it works.
In the Track Editor, click âImportâ 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? Itâs just swag.
Congratulations! Youâve just finished you first line segment. It will
get easier, I promise.
Example 2: Scenery Line
Remember how I mentioned that there were different types of lines? Well hereâs what they are.
In the last example we used a physics line. The rider can interact and ride on those.
In this example youâll 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.
Itâs 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 âpâ to an âsâ 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!
Powerups
Example 1: 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 2: 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 3: 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.
Example 4: Star
Stars are items in the track that must be collected in order to complete the track.
Stars are added with my_track.insStar(x,y)
Stars look like this:
As you can see, stars have no physics and are collected immediately.
Example 5: Slow Motion
Slow motion is a cool feature that allows you to, in a nutshell, make it seem like your rider is riding in slow motion.
Slow motion starts from the time your rider hits it to the time your rider lands on another platform.
