这个程序将有一个立方体、一个下面的地面和一个用于检测地面的光线投射。

在此处输入图像描述

问题

但是光线投射没有击中任何东西，即使我将“方向”部分更改为任何东西

代码

from ursina import *
from random import randint

app = Ursina()

#default entities
player = Entity(model='cube', color=color.orange, texture='white_cube')
main_ground = Entity(model='cube', color=color.gray, texture='white_cube', scale=(5,15,1))

ground_segment_1 = Entity(model='cube', color=color.gray, texture='white_cube', scale=(5,15,1))
ground_segment_2 = Entity(model='cube', color=color.gray, texture='white_cube', scale=(5,15,1))
ground_segment_3 = Entity(model='cube', color=color.gray, texture='white_cube', scale=(5,15,1))
ground_segment_4 = Entity(model='cube', color=color.gray, texture='white_cube', scale=(5,15,1))
ground_segment_5 = Entity(model='cube', color=color.gray, texture='white_cube', scale=(5,15,1))

#entities default pos
main_ground.y = - (main_ground.scale_y / 2 + 0.5)
player.y = main_ground.y + (main_ground.scale_y / 2 + 0.5)
player.x = main_ground.x - 4

#default var
random_floor_spawn = randint(main_ground.scale_x, main_ground.scale_x * 9) / 10
vel_x = 0.1
vel_y = 0

#game launch
def update():
    
    #### GROUND ####

    #follow player
    main_ground.x = round((player.x + 4) / main_ground.scale_x) * main_ground.scale_x - main_ground.scale_x * 2.5 + random_floor_spawn

    #segments
    ground_segment_1.x= main_ground.x + main_ground.scale_x * 1
    ground_segment_1.y= main_ground.y
    ground_segment_2.x= main_ground.x + main_ground.scale_x * 2
    ground_segment_2.y= main_ground.y
    ground_segment_3.x= main_ground.x + main_ground.scale_x * 3
    ground_segment_3.y= main_ground.y
    ground_segment_4.x= main_ground.x + main_ground.scale_x * 4
    ground_segment_4.y= main_ground.y
    ground_segment_5.x= main_ground.x + main_ground.scale_x * 5
    ground_segment_5.y= main_ground.y

    #### PLAYER ####

    #movement
    player.x += vel_x
    player.y += vel_y

    #collide check
    hit_info = raycast(origin= player.position, direction= (0, -1, 0), ignore= (player), distance= inf, debug= False)

    #### CAMERA ####

    #cam
    camera.x = player.x + 4
    camera.y = player.y + 2

    #debug
    print(hit_info.hit)

app.run()

我尝试了一些从网上找到的方法，但似乎没有一种方法对我有用。我怎样才能解决这个问题？

你必须添加一个对撞机。例子： ground = Entity(model='cube', collider='box', scale=(15,1,15))
