Volte posted:This is really awesome. As far as the file format issue goes, I wrote a (simplistic, non-physically-based) raytracer for a course last year and rather than messing around with trying to come up with a sane file format (actually I did that and then gave up), I ended up embedding Lua in the renderer and writing a Lua library/DSL for generating the scene. It's an interesting question. piratepilates posted:You should update your dang blog more often

My game is becoming progressively less an FTL clone and more "Dwarf Fortress ... IN SPACE!" but I'm still having fun with it. The grey letters are room designations (Bridge, Engineering, Quarters, etc.) and each room has consoles and systems.

quiggy posted:This looks awesome. I'm guessing from the graphical style that you're using libtcod, yes? What language are you writing in? Yep, libtcod and python. I'm trying to take a pseudo-pixel approach to it by using small fonts and images with subpixel blitting. I have a lot of public domain 64x64 ship art, and I'll be adding in some particle and fire effects, as well. I'm also trying to stick to using symbols instead of letters for most of the objects on screen, so that the font can later be changed to graphical tiles while still allowing text to be printed using the same font. I'll be keeping them all monochrome though, so I can apply color variations in code.

Shalinor posted:I suppose accidentally flooding the ship with lava is out, but maybe they can ham hand the plasma pressure into causing a severe plasma system rupture? Yeah, the crew will be mostly autonomous, so they'll definitely screw up sometimes and blow up the ship. I do like the idea of flooding the ship with plasma though, I might have to add that in. I'm going to avoid the straightforward combat route of hit points and make it more of a fight to disable the enemy ship and board it. They won't actually explode unless you rupture the warp reactor. edit: Here's a few more ship designs in the combat panel, to show what I mean about simulated pixel art with ASCII:

I've gotten the NROM, UNROM, CNROM, MMC1 and MMC3 mappers pretty much situated (still not perfect on MMC1 and MMC3 but game compatibility has been really good overall). I still haven't touched audio, namely because I know nothing about sound or anything to do with it so I'll approach that as a separate learning experience. I've open-sourced my emulator here: https://github.com/scottferg/Fergulator Still continuing to update it pretty frequently but I'm now splitting my time between this and a Gameboy emu that I wanted to build for the Nexus 7.      Edit: And as these screenshots show, I've replaced the output engine with OpenGL and have runtime scaling as well as overscan emulation (which I'm pretty sure is done incorrectly).

I wrote a chip-8 emulator last night and thought it would be cool to try to compile entire chip-8 programs into lisp and use sbcl's compiler to optimize the resulting code. It can't handle self-modifying code, and I haven't actually written the graphics or input routines yet (besides printing a bunch of 1s and 0s), but this is so cool those can wait.

Start by writing an emulator for the 6502. You can find plenty of data sheets and dumb test programs on the web. Once you're done with that, try writing some emulators for the rest of the stuff. http://emu-docs.org/ http://nesdev.com/ These should hook you up. Because I'm crazy, I'm trying to write one of these but for the Game Boy Color, in JavaScript.

Cross-posting from the Making Games Megathread just to say that holy poo poo it can be really hard making items on a 2D plane (the floating popup arrows) correctly align with an isometrically skewed plane. Took a couple of hours of tiny adjustments but it looks like they're lining up all good now.

I was about to finish my whole-program compiler when I got to the 0xBNNN opcode, which jumps to the address (v0 + NNN). I can't calculate the contents of v0 at compile-time (at least, without major dataflow analysis), and just compiling each possible jump would probably result in an explosion of code. Anyone know how to deal with this, if it's possible?

Yep, lots of misaligned stuff. Fixing the floating arrows was basically a process of making a few functions that line-up sprites based on their width and height correctly. Now I can work this function into all the other rendering parts.

HTML5 / Canvas Go tutorial in order to learn Javascript; it's been relatively painless so far- I can load up boards of 9x9, 13x13 and 19x19. Soon I'll have to implement the game logic which will no doubt be the real challenge.

Added full layout support for configurable ships to my spaceship management game. The enemy shown on the right-hand side of the screen is a weapons-heavy ship with only basic shields and limited engine power for its size, but has to run two huge reactor rooms to power the weapons system. The player's ship has an energy shield up. Now I just need to make them fight!

oTHi posted:I find your use of "Morale: Satisfactory" to be ambiguous. What if I'm an alien despot, and my idea of 'satisfactory' is a bunch of terrified slaves being endlessly beaten with cattleprods? Haha, yeah the lower-right box is all just placeholder text for the moment. It's funny you should mention that though, because one of the races in the game is an insectoid species that will never suffer morale problems. If any other races share a ship with them though, they'll be constantly terrified whenever they see them and morale will be unmanageable unless you can keep them away from each other. I work in python for projects like this because it's so easy to try out different ideas. I figure I can rewrite it in C++ later on if I need to, but every time I try writing a new game in C++ I end up spending so much time chasing down pointer errors that I can't get anything done unless I have it completely planned out from the start.

Nice, you type the line numbers in with your code, so you can go back and overwrite a line, or insert between them with a number between them? Something about that really made you think about what you were doing, and I'm sorry for people learning to code with text editors that they miss that.
