Wie zeige ich Text aus einer Textdatei auf einem Pygame-Bildschirm an?

Question

Ich versuche, Anweisungen für ein Spiel aus einer Textdatei in einem Pygame-Bildschirm anzuzeigen. An dieser Stelle habe ich folgendes codiert:

Wenn ich die Instruktionsfunktion anrufe, passiert gar nichts. Hat jemand eine Idee, warum? Jede Hilfe wird sehr geschätzt!

Answer 1

Sie sind fast da, aber screen.blit braucht ein Rechteck-Objekt neben Ihrem textsprite Diese Aufgabe wird verwendet, um die Größe und Position des Sprites zu definieren. Außerdem müssen Sie jeder Zeile ihre eigene x- oder y-Koordinate geben (sonst werden sie alle übereinander gezeichnet). Eine Möglichkeit, dies zu lösen, ist for n, line in enumerate(f). Dadurch erhalten Sie für jede Zeile einen Indexwert namens n . , wenn die Verwendung aufzählen und Ihre aktuelle screen.blit Anweisung entfernen und ersetzen Sie es mit diesem Block sollte es funktionieren:

text_rect = instructText.get_rect() 
    text_rect.centerx = SCREENSIZE[0]//2 
    text_rect.centery = n*25 + 50 
    screen.blit(text, text_rect) 

Sie ein rect-Objekt für den Text-Sprite Hier erhalten, indem es get_rect() Methode aufrufen, dann dessen Mittelpunkt x gesetzt Koordinate, um die Mitte des Bildschirms zu sein (ich benutze ein contant, um Bildschirmgröße zu halten), dann legen Sie seine Mitte y-Koordinate auf 25 * die Zeilen Platzierung im Array + 50 Pixel Polsterung, und schließlich ziehen Sie es auf den Bildschirm mit screen.blit(text, text_rect)

ich ein funktionierendes Beispiel machte eine eigene Schriftart verwenden, können Sie es here

sehen

In einem früheren Projekt, das ich habe auch ein Objekt für Aufgaben wie das gemacht, sie ist willkommen, zu verwenden oder zu kopieren, wenn Sie möchten, können Sie es here

Sowieso finden, ich hoffe, es half, glücklich Codierung.

EDIT:

nahm gerade an an Ihrem Code, und von dem, was ich Ihren Code sehen kann momentan nichts tut :) Sie Ihre gewünschte Verhalten in der sartscreen() Funktion definieren, aber nie die Funktion aufrufen und damit nichts passiert, dies ist Ihre primäre Angelegenheit, zum Glück ist es eine einfache Lösung, rufen Sie einfach die Funktion am unteren Rand Ihres Dokuments wie folgt startscreen(screen)

Aber warten? Sie werden bemerken, dass ich das Bildschirmobjekt zu diesem Funktionsaufruf hinzugefügt habe, weil Sie Ihrer Funktion eine Referenz des Bildschirmobjekts geben müssen, sonst weiß es nicht, "welches" Bildschirmobjekt Sie sprechen, Sie brauchen Um dies mit jeder Funktion, die das Bildschirmobjekt verwendet, zu tun, müssen Sie Ihrer Funktion auch sagen, dass sie ein Argument erwartet. Wenn Sie also Ihre Startbildschirm- und Anweisungsfunktion definieren, müssen Sie auch das Bildschirmobjekt hinzufügen def startscreen(screen): und def instructions(screen): jetzt wissen Ihre Funktionen, was du redest, wenn screen.fill(COLOR) und screen.blit(text, text_rect)

Andere als einen Anruf, dass es nur eine Frage der kleinen Details ist, aber nach diesen beiden Änderungen Ihres Menü Anwendung schien 3.5 für mich auf python zu arbeiten, aber ich empfehle, dass Sie einen Blick auf diewerfenzum Begrenzen der Framerate (sonst läuft das Spiel auf schnellen Computern superschnell)
