I was making a program that would make a random 8 long code and try to download it from pastebin. but now pastebin isn't loading for me. They hate me now.

This bug just sneaked its way into my code:

for ( uint y = height - 1; y >= 0; y-- )

Heh, Paint writes 0 to the pixel array size field in the BMP header. Fuck standards!

for this reason I never ever loop backwards. I loop forwards and subtract 'i' from the length.

I present to you.... the most annoying feline in existence, on Gameboy Color.

ROM: nyan.gbc
I'll post the source after I've tidied it up a little.
The missing sprinkles on the poptart are due to GBC palette limitations.

EDIT: Thanks to Chris220 for pointing out a small error in the intro notes. Video and ROM have been updated to reflect this.

Decided to try and remake Riven (Myst II) using the original game assets. This means decoding their archive file (not too bad) then their image file (god awful). I fiddled for about 2 hours trying to get image decoding to work before giving up and copying bits of the decoder from someone's open source java project, boy it's so good to see an actual image and not just random garbage.



Next up, decoding the rest of the file types in the archive and seeing if I can get this thing interactive.

Is there actually an advantage to remaking it or is it just a pet project?

Aren't 99% of the things here personal projects anyway?
Anyway, the idea of remaking a game just seems awesome to me. And the fact you have to reverse engineer it then re-use the assets to make a replica is pretty impressive too

Yeah, in my experience the steam version still doesn't play all videos and crashes all the time.

This is an I/O pair from an actual peer reviewed paper:

This is my I/O:

It's not much, but it's getting there.

I have a friend who managed to do it without getting blocked, but when I tried it would go "Whoa! slow down" or something and block me for a few seconds

I had planned to implement textures for OOGL today, but I had so much fun writing the image class that I decided to implement BMP and TGA as good as possible. I just finished the RLE compression for the TGA writer and it actually produces a smaller file than Photoshop! I'm going to implement the GIF, JPEG and PNG loaders/writers tomorrow and then finally add a Texture class. I'm writing the GIF implementation myself as well, but leaving JPEG and PNG up to libjpeg and libpng respectively.

Making an Android version of my game. Not sure what the objective will be yet, but the PC and mobile version should be able to play together.

It's probably because you're running linux. I did some stuff with windows.h for pausing the program and stuff, because I have NO idea how to make portable applications (yet)

No, from what I know it is because your exe is compiled in debug mode, making it require visual studio debug libraries. Not everyone has visual studio.

I have a lot of visual studio versions installed on my computer, including C# 2010 and C++ 2008, and yet i can't run this.

Probably because you need C++ 2010.

I have decided to revive my ComputerCraft masterpiece Roguecraft in my shell because it's already mostly compatible.

Here you can see the upgraded HD graphics, which are now in color. Below my carefully crafted pillar of sand is an Errur, a wild beast with metaphysical properties.



Let's see what happens when it touches you...



Random characters start appearing and "FREE MAAAAARS" is burned into the middle of your screen in flashing colors

Because this exits the game and persists without interrupting use of the shell, it's much more effective and more like a virus. It really gives you more incentive to stay alive than a simple "GAME OVER"

Edited:

Here's the new and improved title screen

Not sure if there were other reasons but the famous quote was directed at me and I don't remember being offended in any way.

I actually did say that I saw grids and distortion in his game and decided to remake it. A few posts above it even.

[Ziks]

I was talking to my girlfriend, and she agrees that the main reason we think that quote was bad was because he invokes his girlfriend out of nowhere just to point out he has one.

Generally you try to abstract your drawing related code into a few generic classes to avoid repeating the same code over and over. In these cases, you store any uniform or attribute locations that you want to update in the class, so you don't have to look them up every time.
If you hide the fact that you need to perform the lookup, people won't bother with caching the value.

Couldn't almost the same thing be said about binding buffers?

Can someone explain how do quaternions work?

Quaternions are like complex numbers except they have three imaginary numbers instead of just one



It follows from the above equation that the product of two different imaginary units is the third imaginary unit, either positive or negative, depending on the order of the operands. Thus multiplication isn't commutative and division is undefined. Addition and subtraction is done as you would with complex numbers.

The simplest way to represent quaternions is as the sum of a scalar and a three-dimensional vector, where the vector represents the imaginary numbers.

If rotation is given as a 4 value quaterion, how do you apply it to a 4x4matrix?

[laylay]

I've never bothered to learn how quaternions actually work, anything I need can be looked up, added to a quat class and then I don't need to worry about it again. Same with anything math related, I'm not too good with maths.

Not really, since in this case the buffers are objects whereas uniform locations are identifiers.
It makes sense for a buffer object to automatically bind itself when performing operations on itself, but performing lookups is hidden functionality.
Perhaps the problem could be avoided by program.LookupUniform returning a Uniform object, the value of which you can then set via the object.

Doesn't matter if it's a debug or release build, you're still gonna depend on the VC++ runtime.



Set "Runtime Library" to /MT on release and /MTd on debug.
Keep in mind that all libraries you link to also need to do this, unless they're system libraries.

I haven't done much programming lately but I went back and improved my ray-casting function. Before I had a loop that incremented a point in the direction of the target until it was inside another tile to check each one. I've now replaced that loop with some line intersection checks. I do a check from where the current point is to the target against each side of the tile the point is currently in. If it intersects with any side then I set the point to that intersection point (and add a bit so it goes inside the next tile).


I also found a bug where ray-casts could go through corners (show below) so I fixed that. Pretty easy fix, I just made it so if the next tile checked is not at the same x and y as the previous then set the x to the same as the previous.



Here's the video i posted of it before:

Just as suggestion, you could have it so the guard or person or whatever chases the player to the last known location after they lost sight. Not sure if you're going to go further with this, but thought I might as well say something.

Well that was a really tough decision. Just started a few weeks ago fulltime(from a few months of parttime) at this company and already I am going to another company. Definitely need to come up with a way to break it to my current boss so that I don't burn bridges. I mean really it boiled down to 3 things which made the final decision easier. Not having to deal with working internationally (no benefits, taxes, etc), having an actual physical office, and a great opportunity to work with other skilled coders working on a fun project..

Anyways hopefully starting Monday. Assuming I can get 2 references by tonight. I got to say the hardest part before it has even started. Is finding 2 references that are available this afternoon(both my work references are sleeping) and finding my SSN card in storage(its that or get a passport).
