Typeerror: Argument 1 Must Be Pygame.surface, Not Str [pygame Using Buttons]

Hello I'm creating a game using pygame and I had some problems. I create some buttons (using images)and depending in some actions the Image of this buttons will change.I will show

Solution 1:

The error is self explanatory:

    gameDisplay.blit(ip, (x,y))
TypeError: argument 1 must be pygame.Surface, not str

The object ip should be a pygame.Surface, instead it is an str. Perhaps you want to create a dictionary:

button_image_dict = {'default_ip': default_ip,
                     'default_ap': default_ap,
                     'chewbacca_ip': chewbacca_ip,
                     'chewbacca_ap': chewbacca_ap}

And then use this dictionary to find the object from the string:

gameDisplay.blit(button_image_dict[ip], (x,y))

Solution 2:

I have a dictionary of characters: cheracters = {'default':0,'chewbacca':1,'Stormsoldier':2}

First, I think that should be a list. All you're storing is item positions.

If I understand what you're trying to do, you want a dictionary for the images

For example

ap = {
    'default' : 'button_menu_ap.png', 
    'chewbacca' : 'button_select_GalaxyWars_chewbacca_ap.png'
} 

nombre = 'chewbacca'
chewbacca_ap = pygame.image.load(ap[nombre])
