When using any control statement in c++ (if, else, while etc.) never put a semicolon (;) after the statement. The control statement affects only what comes directly after it. If you want to affect more then 1 line, you need to put the code in a code block ({..}). if (randomNumberGuess > randomGenera...

I have a question.. I'm currently working on a tile based side-scroller.. The collision detection I'm using now is terrible, I just move the player/mob/item 1 pixel for each frame, and check for collision with solids in their area. If a collision is detected, I simply move them 1 pixel back... I've ...

Let me make this easy for you. Assuming the position (x,y) is the center of the object, you want to check if the distance between the centers is less than the sum of the half-widths for both the x and y axis. int deltax = abs(b->x - a->x); int deltay = abs(b->y - a->y); if(deltax < (a->w / 2 + b->w...

Wait, I still didn't get it, what about this condition? :

Thanks for the tutorial, its been very helpful! I have a question though.. When you showed the simple way to find collision: bool Eternal::IsCollision(Rectangle *a, Rectangle *b) { if ( a->x + b->w > b->x && a->x - b->w < b->x && a->y + b->h > b->y && a->y - b->h < b->y ) { ...

Holy shit! Debugging must be a nightmare!

Well, so far my projects have been quite small, so I didn't know build times were an issue, lol.

How about making two global header files: one that contains forward declaration for all classes, and one that contains the header files for all classes. Then you could simply include the first header in every header file, and the second header in every cpp file. Is it a waste to declare all classes ...

lol, I'm such an idiot.. I don't know why, but I always had this idea stuck to my head, that every cpp file should include only its own header, and any additional headers it needs should be included only in the header.. Never realized how stupid it is that every definition of a class needs to carry ...

Wow, I didn't know it was possible... How can a specific cpp file know what function/data a certain class holds without having the declaration of the class? And also, won't the #define LEVEL_H prevent the the include cycling? I'v tried doing what you've said, and it gave me an error for every line i...

Hi everyone! I'm working on my own little platformer type game (using c++ and sdl). Currently, the engine i'v made can load a level from a file, and you can go around the level , there is collision detection, and a simple camera system, so all i need to add now are mobs, items, and a score system. I...

Thanks, i'll try those

Hi everybody. I'v been learning c++ and sdl. So, now i know c++ (more or less...), i know classes pointers functions etc. I also know sdl - surfaces, event handling etc. What now? I still don't really know how to create a simple 2d game. I only know how to draw things on the screen, and i need to im...

While you're still learning, it probably doesn't matter that much. The more you practise, and the more you come to terms with design and OOP, the better you will get at this. Whenever I want to know the proper way of doing something, I usually look around the web or at other peoples' source and see...
