Marching squares in 2d tile-based game

Изображение
Marching squares - is an algorithm that can generate contour for scalar field (only two-dimensional, for three-dimensional you can look at marching cubes , it has the same idea). It's usually used in computer graphic. Why do we need it? So, let's assume you've generated map as grid of "walls" (we will call it as 1) and empty cells (0). If you'll start placing square tiles at this positions, you will get something like this It could be acceptable for some kinds of RPGs or even strategies, but when you have smooth and fluent gameplay you will stumble on corners of your squares. So you need to make your map smoother. And that's where you need marching squares. Look at the difference: That's how my game looks now: Implementation So, as I said previously, we have a grid of zeros and ones. We can encode every four neighbour cells with four bits, each of them will contain value of corresponding cell. So, if first cell contains "1...

So, it's the first post about game.

At first, I should say, that I'm not just started development. I work on it since summer 2019. But I had a laaaarge breaks, coz I'm student and I'm lazy. So what do I have now?  Map generator! I use cellular automaton cave generator with simple rule: cell type (floor or wall) is chosen according to it's neighbours. It works for 5 rounds and then connects caves into one big cave. You can read more about it in this article . Enemies! Yet just one type of simplest enemies: they are randomly spawn on their spawnpoints (that are instantiated in map-generating time), fly towards you and shoot, when you are too close. I use BFS algorithm to find path from enemy to player and let them go, when player in detection range. On this screen you can see enemies (red-black ships), player ship (drawn by my friend), enemies path (red lines) and their current direction of movement (green lines) Editor! A little bit chunky, but actually it works and I can load level...
