How to add collision detection to 2d objects in ursina?

Question

Hi i was wondering how to add collision detection to 2d entitys in ursina. I am a beginner so this is very difficult for me. Here's my code attached:

from ursina import *

def update():
    if held_keys['a']:    
        player1.x -= 1 * time.dt
    if held_keys['d']:    
        player1.x += 1 * time.dt
    if held_keys['w']:    
        player1.y += 1 * time.dt
    if held_keys['s']:    
        player1.y -= 1 * time.dt
        
    if held_keys['j']:    
        player2.x -= 1 * time.dt
    if held_keys['l']:    
        player2.x += 1 * time.dt
    if held_keys['i']:    
        player2.y += 1 * time.dt
    if held_keys['k']:    
        player2.y -= 1 * time.dt



root = Ursina()

player_texture1 = load_texture('assets/player1.png')
player_texture2 = load_texture('assets/player2.png')

player1 = Entity(model = 'quad', scale = (1,1), texture = player_texture1)
player2 = Entity(model = 'quad', scale = (1,1), texture = player_texture2)



root.run()

Add this to your code: " collider='box' ", e.g. I have a code that goes:

class Floor(Entity):
    def __init__(self, position=(0, -103, 0)):
        super().__init__(
            parent=scene,
            position=position,
            model='cube',
            texture = 'white_cube',
            color = color.rgb(34,139,34),
            scale = 200,
            double_sided=True)

To add collisions to the entity you can just add it as any other parameter:

class Floor(Entity):
    def __init__(self, position=(0, -103, 0)):
        super().__init__(
            parent=scene,
            position=position,
            model='cube',
   ------>  collider='box',  <--------
            texture = 'white_cube',
            color = color.rgb(34,139,34),
            scale = 200,
            double_sided=True)
