IIRC if you rotate then translate, it'll move the object not to an X,Y coordinate, but forward by Y and sideways by X based on the rotation.
I usually have it: Translate, Rotate, Scale.
I've been working on my first game with a storyline.
All my other projects were just games itself, nothing to follow up on. So I thought it would be fun to have a little story for once.
It's called "What Happened?".
I haven't got a lot done really, but I made my first sample scene.

Working on obfuscating my code. Can you guess what it does?

I hope you used resistors with the LEDs or they might hack your face.

Also, why does it seem like it's floating?
The shadow seems to be cast mostly on the 2nd layer of the glass table, also it's actually on an angle because it's heavy on the side with the battery. There is a resistor on there but it's under the switch on that view.
[QUOTE=geel9;27627210]Why do you have a physics engine in a topdown game?[/QUOTE]
Why not?
Because apparently geel9 doesn't realise that physics also control things on the non up/down axis.

Need some advice about threading...
I've currently got a class in its own thread, which in turn might run it's own functions in a 2nd thread.
Is this bad practice?
Also, what's the preferred way to deal with a queue? foeach through the queue or while not empty, pop?

Pop I would say
I finally got my space invaders game in a working condition:

[url]http://filesmelt.com/dl/Space_Invaders.zip[/url]
Left/Right: Move
Z: Shoot
P: Pause
A: Quit (my esc key is broken)
Make sure you run from the shortcut! (Otherwise the program can't find the lwjgl natives - any suggestions to fix this?)
(Also, the game over condition isn't implemented properly yet - it just pauses the game, so you can press P to carry on until the next time you fail)
I've decided Facepunch for Android will not support logging in as long as there is no secure way to interact with the API. I'll start working on the thread listing now (the only part I haven't designed yet, so expect a mockup soon).

I don't know much about the FP API or anything similar. When you say about a secure way to interact with the API, what do you mean? Is there no way to connect securely via https or is it a problem with the API itself?

He is afraid of people decompiling his app, and taking his API key.
All i can recommend is splitting the API into several strings so a simple strings search does nothing.

I guess at the end of the day, there is no way to do it in a truely secure way, even if you jumble the key all over the place. People can still piece it together with not much effort I expect. So really it's something that needs to be dealt with I guess.

No, as mentioned earlier in this thread, I can secure my API key perfectly well by routing all API calls through my server. But people don't want to put that trust into me.

Until compwhizzi fixes the API or people are willing to trust me. I can understand that a moderator does not want to use it, because I could request threads from the mod forum without anyone ever knowing. But apart from that, the only private info that is sent to me is a username, unique device identifier and MD5-hashed password.

I do this very thing in my allocator, the collector class sits in the primary thread, but is also running in a second one. The collector uses a queue which is lock free, so there is no mutex switching, and I could ensure 100% that it is lock free if I was using atomic operations. Assuming you're writing something with C# (I believe that's what you work in mostly right?), you won't have to worry about this, because all read/write operations on integral data types are atomic according to the specification.
Here's the source, so you can get a general idea of what is going on. I'm passing the collector::run function to the thread to execute, and the collector itself to the function. The following while loop isn't the greatest construct, but there needed to be a way to know when the collector was destructing, hence the !self->destruct statements. When the queue is empty of course, the thread is just yielding. At the OS level this causes a decently expensive context switch, so just keep that in mind while working. You may want to look into Windows Fibers as an alternative. They are a lot safer than threads, and a lot faster, since everything exists in the user space. Of course if you're not on Windows, then disregard that :v:
