Before learning, how to Make Minecraft in Python, let’s see what is Minecraft
Game.
Minecraft is a popular video game that is enjoyed by many enthusiasts. It is a
3D block game in which players may interact with and manipulate the
environment. It also has a story mode and is an adventure game.
Minecraft is a voxel-based game. And what this truly implies is that every
single block in Minecraft is a voxel. So these are the things we must make
ourselves. So let’s get right to work on our coding.
Step 1. Modules and libraries for Make Minecraft in Python
To make this Minecraft game in Python, we will utilize the ursina Python
module. It is a Python cross-platform game creation package similar to PyGame.
To install this library, start a terminal or command prompt in the project
folder and paste the following command.
pip install ursina
Step 2. importing library
Import the Ursina Engine and all the Textures that we will require in the
future.
from ursina import *
from ursina.prefabs.first_person_controller import FirstPersonController
app = Ursina()
grass_texture = load_texture('assets/grass_block.png')
stone_texture = load_texture('assets/stone_block.png')
brick_texture = load_texture('assets/brick_block.png')
dirt_texture = load_texture('assets/dirt_block.png')
sky_texture = load_texture('assets/skybox.png')
arm_texture = load_texture('assets/arm_texture.png')
punch_sound = Audio('assets/punch_sound',loop = False, autoplay = False)
block_pick = 1
To load the textures and block you need to download the Assets folder and paste
it where your Minecraft code Python file is stored.
Now there are a few things we need to do to make this all work, and let’s start
by making actual cubes that we can utilize. This will be the most significant
modification that we can do. It would appear appropriate if we applied a more
appropriate texture to it. To do that we created a couple of textures.
Step 3. Making Voxel(Cubes) for Minecraft in Python
class Voxel(Button):
def __init__(self, position = (0,0,0), texture = grass_texture):
super().__init__(
parent = scene,
position = position,
model = 'assets/block',
origin_y = 0.5,
texture = texture,
color = color.color(0,0,random.uniform(0.9,1)),
scale = 0.5)
The third step is to build a new class for each voxel that we want to
construct, therefore the class name will be voxel. And it derives from the
button class. The basic explanation is that anytime I click on a voxel, I want
to make another voxel just adjacent to it. So I need to know where each voxel
is in relation to which button. And in here, we need our init method again and
nothing else for the time being, and we also need the super method with an
underscore to init. And now we must supply a few parameters, the first of which
is parent, as shown above.
The next stage would be to find a position, and the current status is (0,0).
Next, I’d want to make a model of what the object would look like. And for the
time being, this one will be a cube (parameters), but we may use different
forms. The next step is to pass origin_y so that the height and 3D space of
this cube are effectively (0.5), and the final and most crucial item is texture
and color. And both of these things multiplied.
Step 4. Making Minecraft Arena
for z in range(20):
for x in range(20):
voxel = Voxel(position = (x,0,z))
Now that we have everything, we need to create a button for it. The cube’s
current positions are x, y, and z. (0,0,0). To create individual voxels, we
must first create a for loop in which the voxel is set. And if you need to make
it bigger, increase 35 by 35. One of the current issues with this game is that
if you add too many of these fields, the game may slow down. As a result, there
would be a significant amount of optimization work to be done.
Step 5. Creating First person Controller(FPC)
from ursina.prefabs.first_person_controller import FirstPersonController
player = FirstPersonController()
The question is how we can develop a first-person character in all of this. and
ursina makes this super simple. Because it comes with a number of preset
classes that we may utilize to construct a first-person character. We don’t
really have to do anything about it. And really, all we have to do is import
something else first, which is from ursina. prefabs.first_person_ controller.
This is not by default imported into Oceana, so we have to do it ourselves, but
once we do it, all we have to do to create FPC (First Person Character) is to
create a new variable where we store and then call FPC.
Step 6. Making Interactive UI for Minecraft Python Edition
def input(self,key):
if self.hovered:
if key == 'left mouse down':
punch_sound.play()
if block_pick == 1: voxel = Voxel(position =
self.position + mouse.normal, texture = grass_texture)
if block_pick == 2: voxel = Voxel(position =
self.position + mouse.normal, texture = stone_texture)
if block_pick == 3: voxel = Voxel(position =
self.position + mouse.normal, texture = brick_texture)
if block_pick == 4: voxel = Voxel(position =
self.position + mouse.normal, texture = dirt_texture)
if key == 'right mouse down':
punch_sound.play()
destroy(self)
What we need to find out now is how to make this all more interactive. We must
also create and destroy blocks, which will be really simple. Basically I have
written some of these code on my project
https://enterprise.affle.com/mobile-app-development also. Because what we want
to accomplish is, when you push the voxel button, we want to construct a new
block at that location. We develop an input function to do this. Make some
transmissions as well. And then make a to change voxel for voxel texture
Step 7. Changing Different Textures for Coding Minecraft in Python
def update():
global block_pick
if held_keys['left mouse'] or held_keys['right mouse']:
hand.active()
else:
hand.passive()
if held_keys['1']: block_pick = 1
if held_keys['2']: block_pick = 2
if held_keys['3']: block_pick = 3
if held_keys['4']: block_pick = 4
To make Minecraft with python, we need to change the cube texture, and for
changing the cube texture here we created a loop by clicking one to four keys
to alter the voxel texture by Left click and destroying it with the right key.
In simple words. If we press any of these buttons this block pick gets a
different number.
Step 8. Creating the Sky
class Sky(Entity):
def __init__(self):
super().__init__(
parent = scene,
model = 'sphere',
texture = sky_texture,
scale = 150,
double_sided = True)
There are three other components that can significantly help to convey the
game. The first is a Sky Box, the second is a Hand, and the third is noises.
And let us take them one step at a time in Minecraft coding Python. The first
is a skybox, which we emulated in our game by creating a huge sphere with a sky
texture. To do this, we will construct a new class named Sky.
Step 9. Make an FPC Hand
class Hand(Entity):
def __init__(self):
super().__init__(
parent = camera.ui, # This 3D space for Our UI and 2D
space for our camera
model = 'assets/arm',
texture = arm_texture,
scale = 0.2,
rotation = Vec3(150,-10,0), #vec3 is represent 3D space
and the parameters are for position(x,y,z)
position = Vec2(0.4,-0.6)) #vec2 is represent 2D space
and the parameters are for position(x,y,z)
def active(self):
self.position = Vec2(0.3,-0.5)
def passive(self):
self.position = Vec2(0.4,-0.6)
Now the next thing we will going to need is a hand and this one is purely
decorative. It does not do anything besides simulating having a hand it’s a
straightforward thing by creating a class called hand, this one is also going
to be an entity.
