我在2D游戏中的精灵出现问题.我是Directx9的新手，我想制作一个带有图块贴图的2d游戏，以学习如何制作此类游戏.磁贴正常工作，它们全部以48x48的分辨率显示.但是带有虚拟图标(球)的玩家"已调整为58x58.实际尺寸为48x48.我没有在磁贴和播放器精灵之间进行任何更改.所以我问你们，我该如何解决?这段代码也没问题(因为我是Directx9的新手，但我仍然希望它高效)

I got a problem with my sprites in my 2d game. I am new to directx9 and I want to make a 2d game with a tile map to learn how to make such games. The tiles work, they are all displayed in 48x48 as they used to be. But the "player" with the dummy icon (the ball) is resized to 58x58. The real size is 48x48. I did not change anything between the tiles and the player sprite. So I am asking you guys, how can I fix that? Also is this code alright (since I am new to directx9 but I still want it to be efficient)
