XNA C＃創建擡頭顯示器

我想知道如何創建HUD。我目前擁有在設定的座標處繪製到屏幕上的健康，法力和體驗欄。這一點的不足之處在於，當照相機將酒吧保持在設定的座標位置時，我希望他們調整到視口或不受位置的影響，而只是簡單地畫到屏幕上。XNA C＃創建擡頭顯示器

編輯我設法讓HUD使用相機的X和Y座標進行調整。我已經創建了一個單獨的類來繪製HUD，但現在它們不調整。

相機平底鍋時更新座標有什麼問題？ – mrduclaw

當你畫你的健康吧，是它，你指定你的相機矩陣Spritebatch.Begin（...）裏面？

如果您在自己的Spritebatch.Begin中繪製它，而沒有相機，則健康條的位置將相對於屏幕保持不變。

當您使用DrawableGameComponent擴展您的類時，可以使用DrawOrder屬性將其設置爲最頂層。該類會有點不同，你必須重載更新，繪製和LoadContent，但它會一直。

這隻有在使用帶有SpriteBatch的HUD時纔有用。
