1.移动

1.1 沿x轴移动 

from ursina import *
 
def update():
    cube.x = cube.x+time.dt
    # cube.x = cube.x+time.dt*0.5  # 速度为之前的0.5倍
 
app = Ursina()
cube = Entity(model="cube", color=color.red)
app.run()

1.2 沿x和y轴移动

from ursina import *
 
def update():
    cube.x = cube.x + time.dt
    cube.y = cube.y + time.dt
 
app = Ursina()
cube = Entity(model="cube", color=color.red)
app.run()

效果： 

 

2.旋转

from ursina import *
 
def update():
    cube.rotation_x = cube.rotation_x + time.dt*100  # 沿x轴旋转
 
app = Ursina()
cube = Entity(model="cube", color=color.red)
app.run()

效果：

 

3.移动+旋转

from ursina import *
 
def update():
    cube.x = cube.x + time.dt
    cube.rotation_z = cube.rotation_z+time.dt*100
 
app = Ursina()
cube = Entity(model="cube", color=color.red)
app.run()

效果：

 

4.移动+旋转+颜色

from ursina import *
from random import randint
 
def update():
    R = randint(0, 255)
    G = randint(0, 255)
    B = randint(0, 255)
    cube.color=color.rgb(R,G,B)
    cube.y = cube.y + time.dt
    cube.rotation_x=cube.rotation_x+time.dt*100
    cube.rotation_y = cube.rotation_y + time.dt * 100
 
app = Ursina()
cube = Entity(model="cube", color=color.red)
app.run()

效果：
