How to remove a text in pygame? [duplicate]

Question

I am creating a game in pygame which has some buttons and on every button pressed a text is displayed on screen on same position (co-ordinates) but the text is overlapping each other. How can I solve this problem?

Answer 1

If you have provided x and y coordinates to display your text like in this link: https://www.geeksforgeeks.org/python-display-text-to-pygame-window/

Then the thing you can do is make a variable that saves the coordinates where your text is displayed.

When you display your first message on the screen, simply add some value in that variable (in the y-axis if your message is displayed vertically) and the second message that will display will be going to be at the bottom of the previous message.

size = [800,600]
screen = pygame.display.set_mode(size)
black = pygame.color.Color('#000000')
font = pygame.font.Font('freesansbold.ttf', 40)
text1 = font.render('YOUR MESSAGE1', False, black)
text2 = font.render('MESSAGE2', False, black)

#Center
coordinates = (size[0]//2, size[1]//2)


window.fill(white)

window.blit(text, coordinates)
coordiantes = (coordiantes[0] ,coordiantes[1] +5 )#This 5 is the extra addition to y axis
window.blit(text, coordinates) #this will print below 5 pixel from previous message

You can also make a function or class

def setCoordinates(coordinates):
    coordinates = (coordiantes[0] ,coordiantes[1] +5)
    return coordinates

Use this function as

coordinates = (100,200)
coordinates = setCoordinates(coordinates) 
print(coordinates)

Output

(100,205)

Again calling the function gives

coordinates = setCoordinates(coordinates) 
print(coordinates)

Output

(100,210)
