| Nicely done... however in the example screenshots, the wrong pics are linked for both the random pixel and ball bouncing versions. Right now they just repeat the shot of the random rectangle filling. I saw them anyway though, since the naming of the first jpg gave away the naming convention.

| Good explanations of everything. The articles are pretty good, the only thing is that they don't really keep you hooked. He puts the information out in your face and gives you a great explanation of it. I guess this really isn't a problem because most people here like it better that way. I learned a bit more "under the hood" kind of stuff from this tutorial, and that was what I was looking for. Good stuff When will the next one be coming? |

I have a few questions. Right now I am in that "make it faster make it faster" stage of my development, and .05% matters to me.  So, for the questions.Is it slower to use the enum's variables as to just giving your own values to SDL_SetVideoMode? Is the for( ; ; ) faster than the while () I usually use? Is it better to declare SDL_Surface* pSurface (I actually use screen, but for the purpose of your article...) in the beginning or right when you are assigning SDL_SetVideoMode() to it? Thats about it, and I am sorry if these questions are stupid but speed has been the biggest problem I have had with games, so.. |

quote:No. The enum values are just constants. Perhaps more important here is the fact that this isn't a place you'd want to waste time optimizing anyway. This function is going to be called once, at start up, and then possibly if the user changes the resolution - any gains you get here won't matter. At all. quote:There's probably no difference. The assembly should look exactly the same. quote:In terms of performance, there will be no difference. For readability, most people recommend putting variable declaration as close as possible to where the variable is used. |

| Has this article series been cancelled due to the upcoming release of the SDL book in the Prima Game Development series? |

| I have a quick questoin. Why is it that if I up the dx and dy to any int higher than 2, then the ball goes off the screen? -Alex |
