本次，我們將實(shí)現(xiàn)這樣一個(gè)效果：
首先，導(dǎo)入ursina模塊
from ursina import *創(chuàng)建app
app=Ursina()定義Block類，繼承自Button
class Block(Button):
def __init__(self,position=(0,0,0),texture=grass_texture):
super().__init__(
parent=scene,
position=position,
model="cube",
highlight_color=color.lime,
color=color.white,
texture=texture,
origin_y=0.5
)然后，我們需要一個(gè)天空
定義Sky類
class Sky(Entity):
def __init__(self):
super().__init__(
parent=scene,
model="sphere",
scale=1500,
texture=sky_texture,
double_sided=True,
position=(0,0,0)
)因?yàn)槲覀兯械姆綁K包括天空都需要圖片材質(zhì)，所以我們?cè)诔绦蜷_頭寫以下代碼：
grass_texture=load_texture("texture/grass.jpg")
dirt_texture=load_texture("texture/dirt.jpg")
sky_texture=load_texture("texture/sky.jpg")
cobblestone_texture=load_texture("texture/cobblestone.png")
plank_texture=load_texture("texture/plank.jpg")
stone_texture=load_texture("texture/stone.jpg")
bedrock_texture=load_texture("texture/bedrock.jpg")
brick_texture=load_texture("texture/brick.png")
endstone_texture=load_texture("texture/endstone.jpg")
lapis_texture=load_texture("texture/lapis.jpg")
leaf_texture=load_texture("texture/leaf.jpg")
lucky_block_texture=load_texture("texture/luckyblock.png")然后咱們先創(chuàng)建一個(gè)超平坦地形，厚度就只有1層吧，因?yàn)榉綁K多了很容易變卡掉幀
那我們就把底面設(shè)置成基巖吧
height=1
for y in range(0,height):
for z in range(-15,16):
for x in range(-15,16):
print(f"Position:({x},{y},{z})")
texture=bedrock_texture
Block(position=(x,y,z),texture=texture)這時(shí)候，我們需要一個(gè)第一人稱控制器，在程序前導(dǎo)入
from ursina.prefabs.first_person_controller import FirstPersonController然后在程序后面寫上
player=FirstPersonController()順便創(chuàng)建個(gè)天空
sky=Sky()最后運(yùn)行app
app.run()我們還要繼續(xù)設(shè)置放置和破壞方塊的功能，在Block中添加兩個(gè)函數(shù)，用于設(shè)置選取方塊類型還有放置和破壞方塊的效果
def input(self,key):
if self.hovered:
if key=="right mouse down":
Block(position=self.position+mouse.normal,texture=select_texture)
if key=="left mouse down":
if self.texture!=bedrock_texture:
destroy(self)
def update(self):
global select_texture
if held_keys["1"]: select_texture=grass_texture
if held_keys["2"]: select_texture=dirt_texture
if held_keys["3"]: select_texture=cobblestone_texture
if held_keys["4"]: select_texture=plank_texture
if held_keys["5"]: select_texture=stone_texture
if held_keys["6"]: select_texture=brick_texture
if held_keys["7"]: select_texture=endstone_texture
if held_keys["8"]: select_texture=lapis_texture
if held_keys["9"]: select_texture=leaf_texture
if held_keys["0"]: select_texture=lucky_block_texture在導(dǎo)入材質(zhì)后添加默認(rèn)選?。?/p>
select_texture=grass_texture最后運(yùn)行效果如下：
最終代碼：
from ursina import *
from ursina.prefabs.first_person_controller import FirstPersonController
app=Ursina()
grass_texture=load_texture("texture/grass.jpg")
dirt_texture=load_texture("texture/dirt.jpg")

bedrock_texture=load_texture("texture/bedrock.jpg")
brick_texture=load_texture("texture/brick.png")
endstone_texture=load_texture("texture/endstone.jpg")
lapis_texture=load_texture("texture/lapis.jpg")
leaf_texture=load_texture("texture/leaf.jpg")
lucky_block_texture=load_texture("texture/luckyblock.png")
select_texture=grass_texture
