Rendering text in pygame causes lag

Question

I have write function in my functions module which looks like this

def write(size, writing, color, x,  y):
    font = pygame.font.SysFont(\"corbel\"         


        

Answer 1

Avoid to create the font object in every frame.
Create a font dependent on the size before the application loop. e.g:

font30 = pygame.font.SysFont("corbel", 30)  

def write(font, writing, color, x, y):
    text = font.render(writing,  True, color)
    D.blit(text, (x, y))

def print_stats():
    write(font30, f"Red player's hp {player2.hp}", (200, 50, 50), 10, 10)
    write(font30; f"Green player's hp {player1.hp}", (50, 200, 50), 10, 60)

That doesn't solve the issue, that the text is rendered in every frame. If it is still lags, then you have to render the text surface once, when player1.hp respectively player2.hp is changed. e.g:

class Player:
    def __init__(self, color, name):
        self.color = color
        self.name = name
        # [...]

    def ChangeHp(self, val):
        self.hp += val
        self.hptext = font30.render(f"{self.name} player's hp {self.hp}", True, self.color)

D.blit(player1.hptext, (10, 60))
