I decided to defer sleep for a bit, to also do a quick VR test. Dropped my libgoatvr library, and entered my unfinished room in VR with the Oculus Rift DK2.

Ludum Dare 37 “One Room” – progress 02 – VR

Now I’m really going to sleep.

Spent all night modelling the room in blender, and it’s not close to finished yet. Grew sick and tired of boring modelling, so I then pulled code from my free software projects, and loaded a test export of the unfinished room with assimp.

Here’s a screenshot of the first real-time rendering of my room. Rudimentary GL fixed function lighting, and walking around in first person without collisions:

I’m making a game called Tech Raid using my own engine written in C++ and OpenGL. It’s set in an ancient alien spaceship and your task is to loot the place. I guess I was kind of inspired by Gravity Falls. Have a screenshot of the current state of the game:


Stereoscopic tunnel for October Challenge 2015

Hello fellow ludum-dare-ers!
So I split my october in half, wanting to maximize on my chances of crossing the finish line with *something* that makes $1.

First half I cleaned up and fixed a hack I’ve made a few years back. It’s not exactly a game, but it’s got 3D graphics so close enough for me; it’s a stereoscopic 3D tunnel effect. Made a cool menu GUI for it, fixed a couple of stupid bugs, and uploaded to the iOS app-store as free with ads, which was a very enlightening experience.
Turns out, I was done with the code first week of october, but only managed to get it approved, with ads running, 2 days ago! So lesson learned: if I want to release something on the appstore, and have it up at a specific point in time, do it a month early :)

I also decided to release the code under the GNU GPLv3, because what I’ve ended up with, is a very nice example (I think) of a simple UNIX make-based build system for building cross-platform mobile apps. This code currently builds on PC (linux/mac at least, I think also windows but haven’t tested), iOS and Android. iOS has it’s own xcode project (included), but everything else builds from my makefile.

Github source code
iOS appstore page (or search for “stereoscopic tunnel” on the store on an iOS device).

Please check it out if you have an iOS device (it’s free with ads), because right now I’ve just made 40 cents off the ads, and I want to hit the full glorious dollar by the end of october to feel like I’ve accomplished the October challenge :)


The second half of october I was making an actual game. It’s obviously not done, but I’ll extend my own personal october challenge to november, because I really want to release this before the holidays, as it’s an xmas-themed game. I’ll edit this post with extra info if I ever manage to finish, release it and make money out of that one. For now I’ll leave you with a development screenshot:

I didn’t find the time to finish my entry for LD33, so I thought I’d post my progress shots here for posterity, showing how far I’ve managed to take it:




Maybe I’ll manage to finish something next time.

I’m in again!

I’m going to participate for the fourth time in Ludum dare. I’m so excited! :) This will probably be the last time I use my own C++ engine. Next Ludum dare I will probably use Unreal Engine 4 or libGDX. But here is the list of stuff I’m going to use:

Programming language: C++

IDE: Visual Studio Express 2013

Engine: SchoolEngine

Art & textures: GIMP & Paint.NET

Sound: Bfxr

Music: Abundant-Music

Ludum dare is always such a special event to me. I can’t wait to get started. Good luck everyone!

MiniLD #56 – I’m in

I knew I want to participate in this MiniLD for a couple weeks now, but I wasn’t sure if I’ll have any time for it, so I worked a bit on a game I’d submit if it would’ve been finished by this weekend. I’ve overhauled the whole project twice and a week ago I abandoned it, cause it s*#!ed. But last weekend I started learning lwjgl, and now I’m working on a voxel based 3d engine. No, it won’t be a Minecraft clone. It’ll be a fully customizable, editable and moddable dungeon crawler. I just finished the level loader, which loads a 3d level from a single png file. I’m using Eclipse, the engine is lwjgl based, VBOs for rendering and paint.NET for graphics. My goal for this MiniLD is to make collision work properly, create a customizable monster class (and customizable boss fights possibly).

Dungeon 0.3 Dungeon 0.3

I’ll change the textures later, so they fit -Use only 4 colors

If you’re interested in this project, make sure to check my LD #30 submission and vote on this one, once it’s submitted.


Update[20:33; 28.01.2015] – I probably won’t have time to finish the thing, but I’ll do my best.

First Ludum Dare, going for the compo

Posted by
Wednesday, December 3rd, 2014 5:36 pm

So, I think it’s about time to give my engine a spin on an actual game project, and this is good opportunity to see what it can do.

IDE: Visual Studio 2013

Libraries: glfw3.lib opengl32.lib kernel32.lib user32.lib glu32.lib winmm.lib OpenAL32.lib

Tools: Most of my tools are things I wrote, so I can’t really link them, but for sound I should be using Audacity

Engine Code: I’ve included a link to my base engine code below (sorry if it’s messy, It’s my first go at an engine)–a6Jo/edit?usp=sharing

Good luck to everyone competing!

I’m here for LD31!

Loadout: GCC, the WinAPI OpenGL Hello World you get with CodeBlocks, Gimp, some audio lib not sure which. I’ll take part in the compo.

I will make everything from scratch except the font/fonts I’ll be using. You can find them here!

Last LD, I tried to make a 3D, planetary (connected worlds), proc.gen, RTS. Didn’t finish, duh, so let’s keep it simple and ugly fast this time.

Hello, everyone. Iam ‘the’, and i made a game for this Ludum Dare, named ‘KOSMOVALSE‘. It is a game where you fly in open space around asteroids, kill monsters, collect armor and health bonuses and earn scores.
Of course, i planned to make something more, but it is a 48 hours competition, right?


So, let’s talk firstly about two big fails in my game:

  1. Theme. I wanted to do really small worlds in every asteroids with bosses and NPC. And enemies in space just must interfere to player to travel between them. Now it is sounds funny, but every time i planned to make a game, it is looks like Fallout, even not first. So, after a 24 hours when only mechanics was done, i decide to do something more then color changes only when i have enough time at the end of second day.
  2. PyOpenGL. It was first public game i made with PyOpenGL API instead of pure pygame and now i have a lot of comments like “crashed after button pressed”. That is means OpenGl shaders really do not work in many systems even between gamers from ludum dare community and i need to find a way to do something with that if i want to use them. Because of this I spend Monday morning to recompile sources with exceptions and also i very very sad now.


After this i want to say what in my opinion was a good in my game :

  1. Walking on asteroids. I do not know any other 2d games when you can walk on surfaces that placed at any angle (comment, if you know). Mostly people do platformers with simple gravitation scheme and sometimes with wall jumping, because of this it was pretty interesting for me to made a game where player can run on non-spherical asteroids.
  2. Black-white color scheme. I spend a lot of time in first day to understand how the game world will be looks like, especially asteroids (try to write shaders for them, use brown texture), and finally found this awesome simple scheme. I am not god at drawing (you can check my previous ludum dare game for example) and it was really great decision.


In addition this is a history of my ludum dare weekend:

  • Day 1, progress 0% ) O no, they chose this theme =(
  • Day 1, progress 2% ) This green rectangle is player and he is moving, not bad.
  • Day 1, progress 5% ) This connected lines are asteroids, let’s make a collision system.
  • Day 1, progress 15% ) Ok, i did it!
  • Day 1, progress 10% ) No, i dont =( need to find a bag
  • Day 1, progress 25% ) Now it is a lot of asteroids and i can walk on them and fly between them!
  • Day 1, progress 35% ) Made shader for player rocket-pack trace, not bad.
  • Day 1, progress 35% ) This shader for asteroids looks ugly.
  • Day 1, progress 35% ) This shader for asteroids still looks ugly.
  • Day 1, progress 35% ) x_X
  • Day 1, progress 35% ) Why i even decide to take a part in this ludum dare when i can spend my weekends for something else, i will never add a second world and complete this game in time!(
  • Day 1, progress 45% ) This black and white scheme looks cool, draw a player sprites in them.
  • Day ?, progress 50% ) First enemy appeared, need to sleep
  • Day 2, progress 60% ) Now player can shoot, also added new enemy.
  • Day 2, progress 70% ) Now with three enemy classes and routine with they sprites load code looks terribly, no way to found something in.
  • Day 2, progress 80% ) Finally I have a headache from all of this generated sounds.
  • Day 2, progress 90% ) Hey, this menu appeared when i smashed my head on keyboard.
  • Day 2, progress 95% ) Ok, compiled file do not work under Windows, need to load extra GLUT dlls.
  • Day 2, progress 100% ) Uploa….. sleep.

PS. You can find my entry here, some of my previous games available here and here. If you know what is a problem with OpenGl shaders please post some information or link, i will be really happy. Sorry for bad English!.

If someone could compile this to work with windows, I would be so grateful as I am having some problems compiling on Windows (dll hell). 


[W] Forward 
[A] Left 
[S] Back 
[D] Right 
[E] Use Portal or Use Door (with key) 
[Space] Place Portal 
[Esc] Pause

I’ve gotten the basic mechanic done for the game. I’m thinking I’ll call it `The Flipside` as you flip to the other side! The best name ever! /s

I need to improve the graphics, make levels, and other stuff now.

I’m getting ready for the Ludum Dare 30!

Friday, August 15th, 2014 7:42 am

This will be my 2nd Ludum Dare (the last being LD 28).

This time, I’ll be using similar tools but I’m not sure if the game will be 2d or 3d until the theme is announced. The tools I will use:

  • Platforms: Mac, Windows, and (maybe) Linux
  • Language: C++
  • Libraries: SFML, OpenL, (& if 3d, glm)
  • Editor: Sublime Text 3 (with a lot of plugins)
  • Graphics: Photoshop
  • Sound: Garageband, SFXR
  • Writing Instruments: Pen, Pencil, and Paper

I just submitted my  Flappy Jam game (For more information on the Flappy Jam, click me!) and it’s turning out to be pretty interesting! I am actually really proud of this game, as this was one of the first times I have taken more than a few days on a game. The main gameplay is just jumping over some randomly generated spikes. Really. It’s simple, but so was Flappy Bird. That was the point of this jam.

All in all, it was a lot of fun to make, I got to get better in a lot of areas and actually explored a lot of stuff.


It’s not super flashy, but I am actually pleased with the art.

Some things I learned how to do from this jam:
High scores saved to a file, keeps scores after player closes game.
Improved randomized spawning systems.
More reliable and less buggy “scrolling effect”.

I reused the speaker icon asset from my last LD game! Woo! Reuse of assets!


Here is what the death screen looks like, as you can see, it has detected that my amazing score of five was greater than the score in the file (I set it to zero, for the demo.) and tells the player that they beat their score by showing the player a very fancy medal. I designed this system in about two days, without any prior experience with “long term” score capturing options. Pretty darn neat if you ask me.

Anyway, I thought I’d just share that with you guys.

I used the T-Rex C++ engine I made, with OpenGL (SDL_OpenGL) to draw everything, SDL for window and input management, MMSystems for the sound (I’ll get SDL_mixer working, someday.), glut for the text (I’ll get SDL_ttf working, someday.), and SOIL for texture loading!

(You can check out the game here, or you can get the source here. I highly recommend checking out the Flappy Jam and playing some games.)

Game Development; A Four Month Retrospective

Posted by (twitter: @powderblock)
Monday, December 16th, 2013 11:39 am

So, I have been learning C++ for some four to five months now. Last Ludum Dare, I used C++ to make a text adventure game. That was the first ‘official Ludum Dare’ game I made with C++, and I was pretty happy with it. This game had no graphics or sound, and that’s because I didn’t know how to program those at the time. This LD, I made a game with graphics and sound, personally, I think it’s pretty cool I was able to learn these skills in just four months.

Or, as I put it in a post on the second of October; “I am still learning more and more about C++ and OpenGL, so maybe next LD I will have sound and graphics. Who knows.” I am proud that I was able to make something playable in OpenGL and SDL in the span of just 48 hours that also had sounds and graphics. Thank you, everyone.

My progress over just four months, represented by menus.

I will still be doing a post-mortem after the voting ends, I just thought I could share this cool experience with you guys.
