Monogame - Pong Spiel - Beschränkung der Mausbereich

Question

Ich versuche, ein einfaches Pong-Spiel zu machen, und ich habe zwei Probleme, die ich angetroffen habe und nicht scheinen kann, herauszufinden.

Für das Pong-Spiel möchte ich, dass das Paddel des Spielers innerhalb der Hälfte und unter Y bleibt, was bedeutet, dass er das Paddel innerhalb der Hälfte der "Pitch" bewegen kann.

Ich habe es geschafft, das Paddel in der Mitte stoppen, aber es erscheint nach dem Schlagen Mitte. Ist es möglich, innerhalb der Hälfte der Y-Achse zu bleiben, ohne zu verschwinden?

Und das andere Problem ist, dass das Paddel und der Bereich des Spielers in der oberen Hälfte zu sein scheinen, nicht in der unteren Hälfte.

Answer 1

Sie müssen wahrscheinlich Mouse.SetPosition Methode schieben Sie den Cursor zurück auf die gewünschte Rechteck verwenden.

Ich empfehle auch die Implementierung Ihrer eigenen "virtuellen FPS-style Maus" (jedes Häkchen erhalten Sie die relativen Mauskoordinaten und drücken Sie den realen Mauszeiger in die Mitte des Fensters) über allgemeine Mausklasse. Es ist oft eine gute Wahl, wenn Sie Bewegungseinschränkungen für den Cursor haben.
