I have a button that changes color when the cursor hovers over it, and I want to make it so that when the button is pressed, it leaves the color that it has when the cursor hovers over it. There are my unsuccessful attempts to do this in the code. I think I made a mistake somewhere in the "draw" function in the "Button" class.

Test if the mouse is on the button:
button_rect = pygame.Rect(x, y, self.width, self.height)
mouse_on_button = button_rect.collidepoint(mouse)
Set self.button_active when the mouse is on the button and the mouse button is pressed:
if mouse_on_button and click[0] == 1:
self.button_active = True
Set the color depending on mouse_on_button and self.button_active:
color = self.inactive_color
if mouse_on_button or self.button_active:
color = self.active_color
pygame.draw.rect(screen, color, button_rect)
class Button:
class Button:
def __init__(self, width, height):
self.width = width
self.height = height
self.inactive_color = (255, 165, 0)
self.active_color = (13, 162, 58)
self.button_active = False
def draw(self,x ,y, message, action=None):
mouse = pygame.mouse.get_pos()
click = pygame.mouse.get_pressed()
button_rect = pygame.Rect(x, y, self.width, self.height)
mouse_on_button = button_rect.collidepoint(mouse)
if mouse_on_button and click[0] == 1:
self.button_active = True
color = self.inactive_color
if mouse_on_button or self.button_active:
color = self.active_color
pygame.draw.rect(screen, color, button_rect)
print_text(message, x 10, y 10)
However pygame.mouse.get_pressed() is not an event. If you want to toggle the button on and off you have to use the MOUSEBUTTONDOWN event. pygame.mouse.get_pressed() returns a list of Boolean values that represent the state (True or False) of all mouse buttons. The state of a button is True as long as a button is held down. The MOUSEBUTTONDOWN event occurs once when you click the mouse button and the MOUSEBUTTONUP event occurs once when the mouse button is released.

if mouse_on_button and clicked:
self.button_active = not self.button_active
