I have been writing a test function to learn how a mouse 'click' action on a pygame.rect will result in a reponse.
So far:
def test():
pygame.init()
screen = pygame.display.set_mode((770,430))
pygame.mouse.set_visible(1)
background = pygame.Surface(screen.get_size())
background = background.convert()
background.fill((250,250,250))
screen.blit(background, (0,0))
pygame.display.flip()
## set-up screen in these lines above ##
button = pygame.image.load('Pictures/cards/stand.png').convert_alpha()
screen.blit(button,(300,200))
pygame.display.flip()
## does button need to be 'pygame.sprite.Sprite for this? ##
## I use 'get_rect() ##
button = button.get_rect()
## loop to check for mouse action and its position ##
while True:
for event in pygame.event.get():
if event.type == pygame.mouse.get_pressed():
## if mouse is pressed get position of cursor ##
pos = pygame.mouse.get_pos()
## check if cursor is on button ##
if button.collidepoint(pos):
## exit ##
return
I have come across pages on google where people are using or are recommended to use a pygame.sprite.Sprite
class for the images and I'm thinking that this is where my problem is from. I have checked the pygames docs and there isn't much cohesion between methods, imho. I am obviously missing something simple but, I thought get_rect
would make an image in pygames be able to check if the mouse position is over it when pressed?
Edit:
I'm thinking I need to call the pygame.sprite.Sprite
method to make the images/rects interactive?
Well, if anyone is interested or is having a similar issue, this is what I needed to change.
First off, remove:
button = button.get_rect()
Then:
screen.blit(button, (300, 200))
Should be:
b = screen.blit(button, (300, 200))
This to create a Rect
of the area of where the button is located on the screen.
From:
if event.type == pygame.mouse.get_pressed()
To:
if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
The pygame.mouse.get_pressed()
gets the state of all three mouse buttons (MOUSEBUTTONDOWN, MOUSEBUTTONUP, or MOUSEMOTION). I also needed to add in event.button == 1
to specify that this was the 'left-mouse' button being pressed.
Finally:
`if button.collidepoint(pos):`
To:
`if b.collidepoint(pos):`
Using Rect
b's collidepoint method.
