为什么我的文本被复制而不是包装在 pygame 中？

Question

I'm writing a basic text-based game with pygame (I'm not too experienced and this is my first question), and I took word-wrapping and animating the letters in a sequence from the two pages in the class docstring and sort of combined them. Right now, the text animates, but if there's a word that should start a new line it doesn't wrap and behaves as it does in the second attachment (duplicates on new line). Wasn't sure what to search online for this. Python 3.8.5; pygame 2.1.2.

class DynamicText:
    """
    Displays and word-wraps text.

What it does with one line (correct)

What it does with text that's supposed to be wrapped (incorrect)

Answer 1

you should add the line division from the first question linked in this question. As well as you can use something like this:

body = ['Be careful with your inputs, game does not have good error handling!',
                'To choose who begins the game input "a" for computer or "b" for yourself',
                'Press enter to play']
        label = []
        for line in range(len(body)):
            label.append(word_font.render(body[line], True, yellow)) #creates text lable

        for line in range(len(label)):
            disp.blit(label[line], [display_w / 5, 150 + 25 * line]) #positions the text
