私はイメージを片面から消して、もう片方の画面にpygameで置くことができますか？

Question

私はpygame（とコーディング）に慣れていないので、自分のイメージ（xwing）を画面の片側から画面の反対側に移動させる方法を理解できません。現在のコードに誤りがあります。 。 。

Traceback (most recent call last): 
    File "/Users/Grant/Documents/xwingexample.py", line 85, in <module> 
    main() 
    File "/Users/Grant/Documents/xwingexample.py", line 61, in main 
    player_rect.x += change_x 
AttributeError: 'int' object has no attribute 'x' 

ありがとう！

あなたはその後、このエラーを返すplayer_rect.x += change_xので、player_rectに整数を代入しようとすると、ライン75-78をチェックアウトですplayer_rect.xとplayer_rect.yを変更したいので、これを試すことができます。うまくいきます。

if player_rect.x > display_width: 
    player_rect.x = 0 
if player_rect.y < display_width: 
    player_rect.y= display_width
