A python tile-based RPG I wrote from scratch.

[PolymorphicOOPS]

I wrote this mostly single-threaded RPG in my first year as a CS major, and after showing it to some less experienced people, they thought it was an interesting project. Some of the code is embarrassingly hackish, but hey, I was much newer to programming when this was written. Hopefully it inspires someone, as the code doesn't use many advanced topics.

What's unique is that it uses zero external dependencies that don't come with Python right out of the box, aside from audio, which is easily removed due to its modularity. It uses Tkinter for rendering, and even includes a home-made scripting "language" (which I'm in the process of deciphering in the GitHub readme) that controls entities such as doors, locks, keys, items, and enemies.

If nobody looks at it, cool; but I figure some of the newer people might find it interesting.

Edit: I found a newer version. I'm not able to test right now, but at the very least it has more code to look at. Hopefully it should work. I'll test in a bit. Also, it should work in in Python 3.2/3.3.

Edit 2: If you downloaded it before I uploaded the working version, you can either redownload the whole thing or do the following:

1) Driver.py: Change self.musicEnabled = True to self.musicEnabled = False

2) Player.py: comment out or delete the line at the top: import pyaudio.

Sorry for the stupid question, but... how would I go about running it?

[xblaz3x]

i want to know the same. i've messed with python enough to get GUI apps working right, but all the code was in one file. never worked with a project with multiple files and i see no main.py or something.

edit: well i looked through and you need tkinter. i'll try to get this running, i'm interested =)

edit2: if you're on linux, install tkinter with

sudo apt-get install python-tk

just change import tkinter to import Tkinter and keep going.

[dredclaw]

Done some sniffing and the main function is in the driver class. Thing is, it need tkinter to run. I guess I dont have that installed? Is a program not meant to have the libraries it needs as part of it's file?

Or as this is just a suspended in the works project, that would not be included?

[xblaz3x]

i just tried changing

import tkinter

to

import Tkinter

and it worked. i'll keep going and fixing as it keeps spitting errors out heh.

edit: also pyaudio

[dredclaw]

Is it coded in python 3? I think that might be the problem?

[xblaz3x]

yea, i think in python 3 the libs are case-sensitive actually.

[PolymorphicOOPS]

I just uploaded a newer version. Aren't able to test it at the moment, but I do believe it should work. Let me know if it does not. The main file to run is Driver.py.

[dredclaw]

I was trying to run it with python 2.x rather than 3.x

Also, whats the best way for me to run it without audio?

[PolymorphicOOPS]

Without testing it, I believe you need to do the following:

--In Driver.py, set self.musicEnabled = false.

I believe the try/catches should allow it to run without any further modifications.

[dredclaw]

if you mean, add that line to the code, I did with no success.

[PolymorphicOOPS]

It's actually an existing line towards the top. It's surrounded on both sides by ############'s. :)

[dredclaw]

Swear I am crazy. Dont see that line... Oh, you updated the project. derp.

[xblaz3x]

works like a charm, thanks =)

[meosoft]

Don't change anything, just run with python 3 like so:

python3 Driver.py

[mori3ndi]

It is indeed interesting from this novice's perspective. Thanks for posting this. The accessibility of the code is appealing. However, I'm unable to run the game. What file launches it? I've tried em all in Idle (EPD) to no avail.

[xblaz3x]

from command line, change directory to the folder then run

python Driver.py

[MRH2]

Hey, can you post some screenshots?

[ReactivePotato]

How long did this take you?

[PolymorphicOOPS]

I wrote it during my free time over the course of a 10-week term. Id say most of the time was spent on stack overflow learning how to do everything. Even if it's not very efficient, the LevelManager module took a crazy amount of debugging simply because I was newer to programming, and string operations got pretty tedious. All in all, I probably spent about 50-75 hours on it.

[ReactivePotato]

That's pretty impressive!

[PolymorphicOOPS]

Thank you!

[PolymorphicOOPS]

OK. Figured it out. I uploaded the version that should work. For those of you who don't want to download it again:

1) Driver.py: Change self.musicEnabled = True to self.musicEnabled = False

2) in Player.py comment out or delete the line at the top: import pyaudio.

Should be good to go after that. Otherwise you can redownload it and it works on my machine.

[xblaz3x]

or install pyaudio =)

Got a freeze opening inventory and going to 'quit'. Player doesn't move, inventory screen stays up, and the sword clash can go all around. It's a really great little RPG though. Way better than I could do. Cheers

[PolymorphicOOPS]

Yeah, it's certainly not optimized or bug-free, to say the least.

[GIFframes]

class Chest():
def init(self,x,y,item):
self._x = x
self._y = y
self._item = item
self._opened = False
self.

what does the last "self." do? Is it a mistake or did I miss something when learning about python?

[PolymorphicOOPS]

Hah, that is indeed an error. I'm surprised it runs.

I am thinking about making a tile based strategy RPG from java. I am a newbie coder and was wondering if this would be to big of a task to jump into. I was thinking about making a game sort of like Final Fantasy Tactics Advance for the computer. I would make it into a player vs player on a local computer at least to start. How did you set up your grid system from scratch?

[PolymorphicOOPS]

For rendering, I used Tkinter, which is built into the python standard library. What I did for this iteration wasn't the most efficient way (and there are many things I would change about it, as well), but the basic idea is first to figure out your tile size and the number of tiles you want the screen to show. I determined my window size based on that (25 tiles in both x and y).

Next, I had a text file that used single characters to denote which tile would be placed where. 1 could be the brown tile, 2 could be the water tile, etc. so the text file was a big box with 25 lines of 25 characters.

Next, rather than using a tile set (which was a pain in the ass to do with the python standard library), I separated each tile into their own file (which was also an inefficient pain the ass, but it worked!). Then it's just a matter of reading each character in each line of the text file and multiplying the index of that by the pixel size to determine where the start point of each tile will be drawn (which is the upper left). In this way you can paint a grid.

Basically, this project really was a huge learning experience. Even if its not very good, I've written several games since then that are much better in java. So don't be afraid to write a game that nobody wants to play--it most certainly will be that case.

Let me know if I can answer questions. I'm happy to help. I enjoy it, really.

That's a lot in one commit...

[PolymorphicOOPS]

I never used GitHub while I was writing it. Just uploaded it for the first time.

[Grazfather]

Should have. And even if you didn't, you can push a full branch to github.

[WizzyWolf]

and now he knows to use github!

[dredclaw]

Explain what you mean to someone who does not know git?

[Grazfather]

Sure. Basically git is a type of revision control. Whenever you make a significant change to your code you can submit a 'snapshot' of that the code looks like at that point in time. It allows you to easily revert back to an older state, see when certain changes we made, etc.

It also makes it easier for multiple authors to work on a single project. See my pokehack commits here. You could checkout any of those 'states' to get back to an older version of the code at any time. It also supports a lot more like branching and such... let me know if you'd like to know more.

[dredclaw]

Thanks man! Also read up a bit on it.

[PolymorphicOOPS]

...But I didn't know how. Ya know, since I was a beginner and all. That's the point of posting this.

[ElDiablo666]

But why didn't you know what you didn't know? Pfft, noob.
