It's basic trig, though I'm very rusty myself. Here's some Java code I wrote to do that very thing a couple years ago: CODE double thetaRadians = degrees * 2.0 * Math.PI; int myCenterX = (int) (Math.sin(thetaRadians) * length) + centerX; // Advance the cos by 180 degrees to...

I'm quite the fan of http://www.nearlyfreespeech.net . Granted, I don't host popular stuff: just some personal pages. But they claim to host several sites that get slashdotted regularly and to deal with them in helpful ways. And for a small fry like me, they are dirt, dirt cheap. I know cheap...

Nice. How's this?

+1 on just trying. PandoraPanic has whetted my appetite to actually learn C++. But, working with Java (and historically C), I've found it pretty easy to jump into C++. Google SDL for tutorials: it's a nice model. Look at other minigames (e.g., Space Invaders) for examples of how it works...

Poke, I'm starting to toy with a new game. I found that pausing the timer was broken -- missing an exclamation point. You mentioned some similar problem earlier where you had to remove the exclamation point. So I'm not sure. But anyway, I added one in as follows in order to get the timer to...

Agreed. I haven't watched enough to notice other projects dying. But I have no doubt that's what happens. I think part of what makes this different is that there was code involved from the start: a framework, an example, and instructions on how to set it up. I was able to go from interested...

MarkoeZ: I learned something new today: (the answer was 0) Pokeparadox, Thanks for the update! It's fun to see my game in the mix! I have an idea for another game I think would be fun to write. But it, like others mentioned above, it would be intended for the controls on the pandora...

Re: suggestions for Penjin3D: I think a standardized "skip" key would be great. To skip screens with delays. E.g., I display a special message to those who lose in BadVista. I put in a 4-second delay so people have time to read it. But clicking on "Z" will cause it to exit immediately. I think...

OK. Here is my submission, entitled "Bad Vista". Screenshot: It's meant to be a bit spartan. The physics aren't quite as rock-solid as I would like, but seem to be behaving with the current settings. Please let me know if things don't seem right. There are no sound effects. The framework's...

Wow. There appear to be a lot of people getting very uptight about small stuff! 1. It's a game system. I don't plan to use it that way (much!) but that's what it is. I'm excited about it too, but is it worth getting so worked up about? 2. You (and I!) have PRE-ORDERED a device which DOESN'T...

Awesome! Thanks for putting this together! Some suggested includes:ruby CodeBlocks (IDE) source control (I prefer Mercurial; svn/cvs/git all seem even more popular) This is great stuff. Of course, it would fabulous if someone would create a .deb which installs all this stuff as well! (Maybe...

Just my $0.02: Rhythmbox & other desktop-oriented music players don't sound like fun on a tiny device that should be easy to manipulate without a mouse. Maybe a skin/GUI for mplayer would do the trick. Something that will let me pick songs and play them with my finger on the touchscreen or with...

PokeParadox, That was it! I should have tried degrees anyhow. The rotate works great -- if I set the scale. I can deal with that. One minor (but annoying) issue probably concerns my CodeBlocks setup as much as anything: when I quit the game framework, it hangs and I have to kill -9 it. That...

Thanks for the hints! Release mode definitely fixed my slow-down problem. By setting a scale do you mean :sprite.setScaleX(1) and sprite.setScaleY(1)? That seemed to cause it to draw once, but not thereafter. Basically, I have a rectangularly shaped arm which I want to rotate like a...

HOWTO: Start developing a mini-game (in Linux) This is my experience with Linux. The setup may not be helpful to anybody else. This is pretty minimal, too: barely worth the post! But if there's someone else out there as clueless as I am, here it is: SetupInstall code blocks and SDL dev...

PokeParadox, Thanks again for the update! I installed it just now. I'm going to try to post a newbie guide for getting started below. Please feel free to make corrections if the forum will let you. For you, though, I have more questions! Should there be an escape key to quit a mini-game? If...

Thanks! I'll look into that this evening. --Todd

Hmm.... I downloaded the new project. It doesn't seem to include the Penjin3D engine. So I copied in the one that came with the first framework I downloaded. But...In StateSpaceInvaders.cpp:44, Emitter has no such method "setInvisible". I commented this out. Spelling bee plays no music and thus...

Mine's kinda' like skeeball or computer golf. Hold the button down to wind up (rotating the arm like a baseball pitcher). The longer you hold the button, the harder your throw. Try to throw it hard enough but not too much to bounce the ball into the goal. --Todd
