@yahoo5000 You want my favourite (yet simple) formula: x / y = a / b where x is to a what y is to b.

Hello I am quite comfortable with programming (I have practiced from competitive programming websites) and now I want to learn a bit of game dev. And I read about some libraries like sdl, opengl but How do you start? I know all linking stuff etc etc.. But do you read whole source code to start using library??

I know there are many tutorials on youtube.. But for example a new library came up today how does a guy understand it?

If there's an API you fancy using, yeah, read up about it, try things out

ramsay

like reading this stuff for just using openGL?

Chris McFarland

I dunno, I haven't delved into OpenGL, graphics libraries don't interest me. Maybe look for a tutorial

Whoho! I finally wrote my first path finding function!

I never seemed to get just how to do that, so I just tried to write it instead of trying to fully understand those articles hehe

Q: How do I calculate player retention in a single-player RTS game?

Suppose there is a typical desktop RTS game without online multiplayer on a Windows platform, like the original Warcraft: Orcs & Humans. It still connects to a server to log basic anonymous info about the player's sessions. Now it would be interesting to see customer (player) retention in an indu...

@Ramsay I get what you are asking. Starting out is quite overwhelming. There is no secret, you need to read and try. After a few years of this you will understand what I mean.

The first time I got into game development I got so frustrated that I quit

Went back to making apps

Start small. Make super simple demos. Work your way to larger stuff.

ok i did improvement on calculations now its seems to by much better

//scroll[0] scrolling bar
	//scroll[1] scrolling slider
	//optList vector of all options
	// listindex index in vector
	slidery = Box.bottom + (((float)scroll[0].GetHeight() - scroll[1].GetHeight())  / optList.size() * listindex);
	slidery = std::max(Box.bottom, slidery);

so its (scrollbar height - scrollslider height ) / total options * current index in option vector

A: error LNK2005, already defined?

Why this error? You broke the one definition rule and hence the linking error. Suggested Solutions: If you need the same named variable in the two cpp files then You need to use Nameless namespace(Anonymous Namespace) to avoid the error. namespace { int k; } If you need to s...
