Coded in Java, a general-purpose programming language that emphasizes speed and lightness over the grand capabilities of more powerful tools

I stumbled a bit while reading that. There is a comment to be made about notch's use of java, both good and bad, but I don't think speed and lightness when I think java, especially in the realm of 3D games.

I do think it was a good choice for cross platform play and modding though.

Glad I wasn't alone in thinking Speed and lightness seemed odd especially when talking Java

While it's obviously questionable from a technical perspective you can argue that Java, as a fairly good trade-off between abstraction and power, is faster (in terms of development iteration) than a lower level language and lighter than using a full blown engine (like unreal engine).

I don't think he chose Java so much as that was simply what he knew at the time.

I wonder what are the grand capabilities it lacks? Is C++ a more powerful tool filled with grand capabilities? It does not feel right, although it sure is a Swiss army knife full of sharp and pointy tools in a "Don't look into laser with remaining eye" sort of way.

Is C a more powerful tool? Absolutely not. It's powerful but not that expressive.

Both languages are relatively low level and uses application memory management. I think it's only the latter that really matters when writing 3d games and other low-latency programs to be honest.

But I think the slow part of minecraft is the terrain generation, and I think it's mainly because the world is rather large and the algorithm is complex, not because java is slow or that the gc is a bad idea.

I don't think that the Windows 10 version run noticably faster, but I'm not completely sure that it's C++ and not C# and gc:d.

Java has quite a bit of memory overhead which exacerbates Minecraft's inherently high RAM requirement. That plus frequent GC pauses make Java a suboptimal choice for Minecraft long term. (But it may have been the right choice for Notch back in the day.)

Yea it's a vague statement for sure. Maybe "more powerful tools" means Unity or a game engine, but it's not certain, and that sentence will just keep looking strange to me.

My kids run it on their X201s. The Windows 10 version is massively faster, providing really fast rendering. Minecraft 1.9 doesn't even seem to support setting the fullscreen resolution, so it's always pushing 720p. I'm not kidding when I say it's literally unusable: 1 frame per several seconds.

Unfortunately the W10 version is very cut down, lacking lots of things. It's possible the main difference is OpenGL v DirectX on the Intel integrated cards. But the graphics are basic enough that there should be some way to render them quickly regardless.

The biggest thing compared to C and C++ (or even C# and Go) is probably the lack of user-defined value types. So if you want to create an array of Point2D objects, in Java it will be an array of pointers to heap-allocated objects (each with additional per-object overhead), which is really bad for cache misses, memory consumption, GC pressure etc. C# is a pretty similar language that is popular for game development (with Unity) but unlike Java it supports value types.

The point may have gotten lost in translation.

I think the point here is that a lightweight game engine was used (written in LWJGL which is a wrapper for native graphics APIs), rather than something full blown like Unity/Cry/Unreal.

Keep in mind, Notch didn't write the java library that did his rendering, the light weight java gaming library or lwgl. It has reasonable performance and, as advertised, is lightweight.

The key to minecraft is that it stylistically embraced a really blocky rendering style with low resolution textures. That made a game that could be very open vistas, be malleable and run on any modern device.

s/Minecraft/Stardew\ Valley/ and you get the 2016 version.

Wow. I wasn't aware of this Harvest Moon clone. Brings back memories.

IMHO Markus Persson wasn't a "bedroom programmer" in the pejorative sense, he programmed as a professional for King.Com for four years before venturing into the land of indy dev.

kpil4• 10 years ago

Yes.

I think he was a rather creative developer that managed to create the game that he wanted himself as a kid.

Maybe we can just sort this article under "slighly uninformed opinons" and carry on with our lives...

I am interested in how he learnt about back face culling issues though
