• Slow writing HDD speed, Ubuntu 12.04 64-bit, Thinkpad T520i

  - by pyc

• Circular movement - eliminating speed ups near Y = 0

  - by Fibericon

  I have a basic algorithm to rotate an enemy around a 200 unit radius circle with center 0. This is how I'm achieving that: if (position.Y <= 0 && position.X > -200) { position.X -= 2; position.Y = 0 - (float)Math.Sqrt((200 * 200) - (position.X * position.X)); } else { position.X += 2; position.Y =…

• Is pitch and speed the same thing in audio programming context?

  - by mystify

  Pitch means "perceived frequency". Nice. But when I make pitch very low in OpenAL, sound plays a lot of times longer. If I make it very high, sound plays very short but with high frequency. For me, logically the consequence of making slower or faster. Or is pitch != speed?
