我最近一直在學習LWJGL,因爲我已經使用了Java一段時間了,並且我已經瞭解到,由於沒有很多LWJGL教程/參考資料,我只是使用搜索OpenGL教程,因爲我知道LWJGL就像一個OpenGL的Java端口(我認爲這就是你如何描述的),它們基本上是完全一樣的,除了我總是需要調整一下,而且我做了這個代碼(基本上全由我自己),當我運行它時,它只顯示一個瓷磚地圖,但它應該顯示16個瓷磚!爲什麼是這樣?OpenGL(LWJGL)TileMap只顯示一個圖塊

我實現了你的建議,但它仍然無效。更新了上面的代碼。 – n1ghtk1n9
您是否曾嘗試在'while(!Display.isCloseRequested())'循環中添加glloadidentity()作爲第一個命令? (像我說的每個循環的開始? –
