All language subtitles for 2. Gridss

Grids are the most common way to create 2D environments.
1

But don't be fooled by their 2D capabilities, as they can also be used in 3D games that are limited
2

to a flat surface.
3

A grid is a set of lines.
4

As you can see here, and columns that are put together to form a 2D table. Where each point or cell
5

can be referenced by a pair of a row index and a column index.
6

If you want to learn how to implement grids, head over to the bonus module and look at data structures.
7

Let's find out what are the pros and cons when using grids.
8

The first one is that it's very easy to use: create a 2D array of elements and it will already work with
9

the map structure.
10

If the map was designed to support the grid in the first place. It supports real time changes.
11

Does your game have actions that change the map?
12

By having a grid, you can easily set what's walkable and what's not, and the best part is that it's
13

already implemented in most common game engines
14

Godot included. All of these pros...
15

That means that grids must have some cons and they do have: They have a fixed shape.
16

It will always be a square shaped. Of course,
17

you can disable the sides to make interesting shapes, but is very much limited to that.
18

It cannot support height variation and if your game has hills, valleys, then a grid might not work
19

for your game.
20

In general, it cannot provide too much environment variation.
21

Having a grid city might not be exactly fun in some cases.
22

If a grid-like structure sounds too restrictive to you, then you might want to try graphs.
23

Let's look at them right now.
