For CodeCademy I was tasked with creating a Terminal game. I knew it was coming and had been preparing for weeks for it as I plowed through the Computer Science course, fully confident that I would tackle this project with ease.
I think I stared at my IDE for about 2 hours before I figured out how to get started. I began building a class I simply called "Human". This was gong to represent both myself, and the NPCs in my little text-based world. Oh the grand ideas I had. Hours blew by and I typed away.
Before I realized what was going on, I had overloaded myself. Every time I had a though, I'd insert blocks of code to make that a reality and the project blew up beyond a simple little terminal game. I could have saved myself hours if I had had a little humility about my actual capabilities. Instead hours turned into days, and then a week later I have about 400 lines of code and none of it works.
I had managed to exhaustively iron out the exception-causing bugs, but nothing behaved as I intended. NPCs would get stuck in one room, weapons (the second class I created to satisfy the '2 Classes' Requirement of the project) weren't being properly equipped. Combat was hilariously broken, and I, as the player, couldn't even leave the room I'd crafted to enter one of the other two.
So today I saved the project as a WIP to visit later with better tools and reduced it significantly to you and your opponent. No great fanfare of worldbuilding, no trying to move around from room to room, not even the complex turn-based battle system I'd dreamed up.
You pick a name, you pick a weapon, you enter the main loop, and you and an NPC whack at eachother (or defend) until one of you falls unconscious.
I did get to keep one fun little toy I'd dreamed up. I envisioned a mace as a special weapon, one that could immediately end the fight by knocking your opponent unconscious. I reduced the chance of this to nearly nothing, and was treated on my first playtest to being immediately defeated in the first hit by a mace wielding NPC.
Unfortunately I didn't think to document my journey with screenshots, so all I have is post-completion. The final product. Behold the culmination of a week and a half of free-time consuming effort:
You enter the arena to the roar of the crowd. A man in the emperor's box with a booming voice shouts, "Welcome, one and all, back to The Arena!" The crowd roars again. After the din dies down, the announcer continues. "Today, we see battle between two fierce competitors! First, we have Leonius Libo using a Dagger!" Once more the arena erupts in cheers, some even chanting Leonius Libo's name. "And second, we have... Enter your name: Hathrel using a... Select a weapon from the following: DAGGER, GREATSWORD, LONGSWORD, MACE Mace!" the crowd erupts into cheers again. Some chanting your name this time. "Without further ado ladies and gentlemen, let the battle BEGIN!" he shouts, the crowd erupts in roars and your opponent rushes you!A printout of the game runtime
