Скачать или смотреть Direct2D Tutorial 6: Real Time Game Loop

In this video we'll look at creating a real-time game loop. The loop itself consists of two method calls: Update() and Render().

At the moment, we don't have the infrastructure in place to make these method calls. i.e. there's no game objects, no level classes or anything like that. So today we'll just render a little bouncy ball in real-time. We won't use method calls to Update and Render, but we'll change all of this shortly when we make the backbone to a game engine.

It's interesting: What looks like a bouncy ball is actually very simple, and it's actually nothing like real-world physics. The more we get into rendering graphics and physics, the more apparent it becomes that we're taking some serious liberties! Matter of fact, there's no chance a modern computer could hope to simulate real physics, let alone render it on the screen. So what do programmers do...?

They cheat till the cows come home, and the player has no idea! That's not a bouncy ball at all, that's just a float called "y" being rendered to the screen!
