Game Development / Newbie & Debugging Questions / Re: Vector Drawing?

on: 2013-01-29 01:35:49

I'm not sure, but there seems to be some weird example specific code inside of Vec2.java:

try to replace this in the draw method:

1
2
3
4
5

public void draw(Graphics g)
{
    int [] iv = convert();
    g.fillOval(iv[0]-4,iv[1]-4,9,9);
}

with this:

1
2
3
4

public void draw(Graphics g)
{
    g.fillOval(v[0]-4,v[1]-4,9,9);
}

don't know what your coordinate system looks like, so can't say if that'll help...

The problem with high weights for impassable cells is that A* will take these cells if there is no other way to get in. e.g. if the target lies in an isolated area. If this behaviour isn't desired, then it's better to not include these impassable cells, as sproingie and Best Username Ever already said.

I like Ruby and C more than Java, but I still prefer to write games in Java. Ruby is very nice to write, Java is very verbose compared to Ruby, but Ruby gets inconsistent pretty fast and the RVM (Ruby VM) is inferior to Java VM, I use Ruby only for web and Linux scripts. C is close to the metal, it's very easy, without much magic behind, but also very verbose and there is no VM at all, so I've to care about memory, collections, etc. which is nice, but not suitable for fast prototyping. I use it only for fun or Linux hacking. Java is much easier to port to other platforms, and there are many ways to publish the game (Applet, Web Start, JAR, etc.). Also Java offers a really decent VM, that is very fast and is suitable for games. Also Java runs on my favorite operating system. I'm developing exclusively on Linux atm. But I think the most important advantage of Java is, that I can focus on making the game and deliver it to the public much faster than with other languages. I hate PHP abysmally, and always trying to avoid C++ intuitively, don't know why...

4	Discussions / Miscellaneous Topics / Re: How to fetch an AJAX call on a LAN machine?	on: 2013-01-25 14:11:25
exactly. You simply connect to the IP. Or if you wish to access the server by name, you can link an alias to IP in the hosts file and then access the server by this alias. AJAX is no different than normal HTTP, it's only issued asynchronously by the client. If you want your server to talk back to the client, you have to hold the connection open, until there is a message from the server. But still the connection is issued by the client, see http://en.wikipedia.org/wiki/Comet_(programming) . Or simply use WebSockets (HTML5) if allowed.

AfterFX. Not really cheap ($999): http://www.adobe.com/products/aftereffects/whatisaftereffects/ but if you know someone who has it or you don't mind buying it, it's a very powerful tool. Check http://www.videocopilot.net/tutorials/ if you want to see how it works and how powerful it is. I've bought CS3 Production Premium Package some years ago (Student Version) for ~310€ and it's worth it

unfortunately I can't start the webstart examples from the site, as the lwjgl-1.1.4-extension.jnlp doesn't specify lwjgl natives for linux x86_64.

but wait, should't it load lwjgl.jar.lzma, as it has lzma.jar included?

I showed Minecraft to few of my friends and they all said it's not worth playing, because they don't like the graphics of it... weird, it never bothered me... I played it with an enhanced texture pack (Painterly Pack), but now after the update I decided to stay with the original textures... kulpae

Quote from: Nate on 2010-09-20 10:49:16 Right, kulpae. I get that, and that is what i expected. However, when I play, that doesn't happen. For example, I tried it again. I punched the crap out of some sheep. This allowed me to put down some concrete blocks (likely they are actually wool). I explored until nightfall, finding only the usual farm animals and flowers. When it got dark I repeatedly jumped and put concrete blocks under me, so that when the bad men come they would not kill me. I watched a spider, some zombies, and a green creeper thing for a while from my woolen perch. Eventually I got restless and accidentally fell off. I ran and some jerk shot arrows at me. I rounded a corner and, weakened from my fall, a zombie killed me. Where is this gameplay depth you speak of? Well, at daytime I enjoy building my empire and when night breaks in I defend it (or when I can't, I hide).. . I must admit, that minecraft alpha makes much more fun, than classic... well with classic I tried building some houses or towers, that's all... nothing more... but with MC-Alpha I have much more fun extending my buildings, looking for rare ores, be off to the sea and explore new places... I'll make a youtube video of my "work", so I can show off a bit If I can put this world (MC says its 20MB huge, but on my hdd its > 120MB) to a minecraft server, so others can join, colonize islands and we could trade and so on.. that would be cool So as you can see, the fun lies not in the goal of the game (like in real life, nobody gives you objectives, when you come into this world...), but in the process of achieving something, that the player choose for himself. If you don't set your own goals, you won't achieve anything and thus it won't be fun. Use your imagination and build something (tower, house, cave,...), then try to expand it or look for better materials and enhance your building ... or look for redstone and build complex logic circuits...

15	Games Center / Featured Games / Re: Minecraft	on: 2010-09-20 08:42:39
I think people are curious about this new kind of play, so they have a stronger motivation not to give up... It's kind of a logical step after lego, your persistence remains, they have a feeling, they can learn something or extend their visual capabilities, like children do. So they are not giving up so fast... If they see games they already know or whose playing mechanics are very familar to them, they seek for another stimuli inside of this games and by finding none they leave. Minecraft manages to combine two things: build what you love (as its a long process to build something great) and defend what you love (creeper's tssss...BOOOM, etc.) But building alone is a big motivator, as it allows people to create third dimensional things from their mind easily (easier than with 3D modeling tools, but not as accurate)... cheers, kulpae

Quote from: gouessej on 2010-09-10 22:05:21 Quaternions are not enough. Sorry, it is not the title of the next James Bond Quaternions + non-eulerian transforms solve this problem. Quaternions + eulerian transforms don't solve this problem. I wrote a very long report about that in French in 2006. didn't know that, thanks for the info.

back.rotateX(yaw);
back.rotateY(pitch);
back.rotateZ(roll);

It is a good way to get some gimbal lock... Sad

Quaternions solve this problem.
