Learning to Code - A Sprite Break

Jennkryst

@Jumpscare I got linked to this here thingy:

@IoleRae said in Learning to Code - A Sprite Break:

https://codecombat.com/

And there is a section where you tell your hero sprite to hero.moveTo(2), and there is a dog sprite standing there, but no instruction on how to give the dog head pats.

This is criminal.

@Jennkryst

Sorry, I don’t know how to code anything besides Evennia.

Roz

@Jennkryst This is a really weird response to someone typing out a bunch of stuff to try and help you after you asked for help.

Disclaimer: I typed this all up from memory.

I can’t type up a damn thing from memory without looking at it 4,000,000 times, this is very impressive to me lol

Jennkryst

@Roz @Jumpscare said she didn’t know what any of what I was talking about meant, so I explained.

I should have clarified the code combat people are the criminals, for not letting me pet the dog.

ahem

Right now, I’m stuck at trying to even install evennia onto the Linux virtual machine (which finally worked on the 4th try, horray!) So progress is happening, just slow. Efforts to resume after work.

Jennkryst

This took a dumb amount of time, but fear me.

Rucket

this is a very random comment but

every game should have a command to pet the doggo. doggos good.

dog

that said, this is an interesting thread to follow!

Jennkryst

… and now I’ve rebooted, and

evennia start

evennia: command not found

flop

edit: Two hours trying to make it work on my own, I gripe, and then it works before any troubleshooting actually occurs. I hate it here.

Hobbie

You could theoretically run Evennia and all its prereqs inside a Docker container to avoid that.

However, that’s advanced work that involves mashing together two ideas that work well in a vacuum.

EDIT: Even more advanced theory, with Evennia running in Docker you could theoretically hook it into k8s to make it autoscale when under load. Why you would do this is another question.

Istus

@Jennkryst You likely did not reactivate your venv.

Jumpscare

@Istus is right.

source evenv/bin/activate
Make sure you’re in the same directory that you setup your venv before doing this command.
python3.9 -m venv evenv
I don’t know what this does, but it’s necessary from what I’ve seen. I think it sets what Python version you’re using. The latest version of Evennia requires 3.9 or 3.10.
cd game/directory
Replace game/directory with the name of your game’s directory.
evennia start
Now you get to shout orders to Evennia.

evennia start
Now you get to shout orders to Evennia.

#2 on your list is what creates the venv in the first place, so if it’s already established, then this step isn’t needed. Specifically, it’s telling Python 3.9 to run the venv module and output the virtual environment to the evenv directory, which will be created inside the directory you run the command from.

This.

Step 1, that source command, it sets up your terminal window to know where to find your specially set up python that your Evennia is using.

So you have to do step 1 every time you open your terminal and get to work.

Step 3 tells your terminal what files you want to work on. So you do that after.

Step 4 starts evennia, the actual program.

Step 2 is part of the install process and should not need repeated.

Thanks. I must’ve made a mistake at some point.

I consider it a miracle that I’m 97% done with making a game in Evennia and it hasn’t exploded in my face yet.

@Jumpscare Revisiting THIS, (I trouble-shot a bug! There is an erroneous space up in (current _mod + value…) and it made things go wobbly, but I fixed it, huzzah!)

… but there is another error getting thrown.

self.db.characteristics = {

name ‘self’ is not defined

Jumpscare

@Jennkryst
Where is that code? Where’s the }? I need to see more. When asking for help on errors, it’s best to post the entire method that the error comes from.
But it sounds like your indentation might be wrong and you’ve wandered outside of a method.
Also, congrats on finding errors in my hastily typed tutorial!

So this is what the bit in characters.py looks like:

self.db.characteristics = {
    "Agility": 1,
    "Brawn": 1,
    "Cunning": 1,
    "Intellect": 1,
    "Presence": 1,
    "Willpower": 1
}

Now, in terminal:

(evenv) jennkryst@Ubuntu:~/muddev/FFGTest$ evennia start
Traceback (most recent call last):
File “/home/jennkryst/evenv/bin/evennia”, line 11, in <module>
main()
File “/home/jennkryst/evenv/lib/python3.10/site-packages/evennia/server/evennia_launcher.py”, line 2344, in main

File “/home/jennkryst/muddev/FFGTest/typeclasses/characters.py”, line 16, in <module>
self.db.characteristics = {
NameError: name ‘self’ is not defined

But it sounds like your indentation might be wrong and you’ve wandered outside of a method.

I also forgot a space in there, fixed it, but the problem persisted.

Also, congrats on finding errors in my hastily typed tutorial!

The terminal deserves all the credit, it pointed me at the line in question, I just stared at it until I figured out why. But thanks!

… also, I’m sure I have more issues than just figuring out the self.db problem, but.

@Jennkryst Is this code snippet just hanging out by itself in characters.py? If so, that’s the source of your error. It’s hard to diagnose your error without seeing your code in full. I presume this snippet is supposed to be in, say, at_whateveritscalled_creation().

Jumpscare

@Jennkryst
You might’ve missed me saying it, but it needs to go in the at_object_creation method.

A method is any of those lines that start with def. All of your code in characters.py, rooms.py, exits.py, scripts.py, accounts.py, channels.py and objects.py needs to go inside methods. And methods go inside the class that the file defines.

For the most part, all of your def lines should be at the 1st indentation, and the code inside at the 2nd indentation and beyond.

class Character(DefaultCharacter):


    def at_object_creation(self):
        """
        Called only at initial creation.
        """
        self.db.attributes = {
            "Grit": 2,
            "Presence": 2
        }

Code in commands/commands.py is different and each command is its own class.

class Sayhi(Command):
    """
    Tells the character hi.
    """
    key = "sayhi"
    aliases = ["sayhello"]
    lock = "cmd:all()"
    help_category = "General"

    def func(self):
        self.caller.msg("Hi!")

And the command needs to be added to commands/default_cmdset.py. Most of the lines below should already be in your file. What you add are the first and last lines.

from commands.command import Sayhi

class CharacterCmdSet(default_cmds.CharacterCmdSet):

    "key = "DefaultCharacter"

    def at_cmdset_creation(self):
    "Populates the cmdset"
    super().at_cmdset_creation()

    self.add(Sayhi())

Yeah, it’s hanging out by itself, so I thought that was the code in full.

It’s more ‘I read what you said and then assumed I knew what you meant by it’.

…

Alrighty, the game is starting again, all new errors are being thrown client-side, so I’ll see if I can figure those out before checking back here.
