I'm taking a masters degree in informatics engineering, specifically in the areas of computer graphics and applications engineering at University of Minho, Portugal. I like digital arts and graphic design - http://cargocollective.com/joxnas - and I play guitar in my spare time. Occasionally I write a post in my blog too: http://imagine-random.blogspot.pt

comment Panning a 3d viewport in 2d direction with rotated camera
In actionscript I think the atan2 function does exactly the same... try it. Anyway, if it doesnt work , use this: public static float vector2dAngle(float[] vector){ if(vector[0] != 0){ return (float) (vector[0] > 0 ? Math.atan(vector[1]/vector[0]) : Math.atan(vector[1]/vector[0]) - Math.PI);} else{ return (float) (vector[1] > 0 ? Math.PI/2 : -Math.PI/2);} }

comment Can I randomly generate an endless road?
So we are in a tile and we see the 8 tiles around us which can be walkable or non walkable. When we go to one of the walkable ones, are the 8 around it regenerated randomly (Meaning the tile we were previously can change) ? Or are the tiles we never saw the only ones that are generated? Cause if it is the first option the question doesn't make much sense.. You need to explain yourself better

comment Why does my game loop speed vary on different platforms with the same hardware?
You should also measure your game performance in render time instead of fps,since fps is not a linear measure. E.g, a drop from 600 fps to 300 fps (+1.67 ms of render time) is not as bad as a drop from 30 fps to 28 fps (+2.38 ms of render time). In your case its a diference of 1.33ms between windows and linux which is not too Much if you ask me. If your game runned at around 30fps you wouldnt even notice the difference. See this: mvps.org/directx/articles/fps_versus_frame_time.htm

The fact that the question title changed makes this answer look like it doesn't belong here...

I added an answer, thought I'm not really sure if it is what you wanted. About different FPS in different platforms, it probably has to do with the drivers being more optimized in different platforms, and also the way each OS deals with memory / threads / etc.

when you say faster, are you refering to the game logic or the FPS ?

comment Why does my game loop speed vary on different platforms with the same hardware?
I don't get it...You say the speed of the game is not stable, but your functions receive the elapsed time... So for instance, if animal A walks 1 unit per second, and you run update(2), it walks 2 units. It walked 2 units in 2 seconds which makes it walk 1 unit per second. If you give update function the argument 3, the speed would be the same, so what Am I missing here? The game logic shouldn't be running at a constant speed?
