Question

我正在尝试创建一个按下键盘字符的程序，然后以6种不同的字体显示（在六个不同颜色的方块内）。我一次只显示六种字体，但我希望能够在用鼠标左键单击时切换字体。截至目前，右键单击将鼠标指针下方的字体转换为斜体。

我的问题是：我如何制作一组PFont变量，所以当我左键点击一个＆＃34;字符＆＃34 ;;我可以通过一些字体循环，即（Helvetica，Futura，Optima）。

我的代码如下：

＆＃13;

boolean button1 = false;
boolean button2 = false;
boolean button3 = false;
boolean button4 = false;
boolean button5 = false;
boolean button6 = false;

int x1 =0;
int y1 =0;
int w1 = 400;
int h1 = 600;

int x2 = 400;
int y2 = 0;
int w2 = 400;
int h2 = 600;

int x3 = 800;
int y3 = 0;
int w3 = 400;
int h3 = 600;

int x4 = 0;
int y4 = 600;
int w4 = 400;
int h4 = 600;

int x5 = 400;
int y5 = 600;
int w5 = 400;
int h5 = 600;

int x6 = 800;
int y6 = 600;
int w6 = 400;
int h6 = 600;

您可能无法运行代码，因为我在数据文件夹上有vlw文件。我不知道如何将其包含在这里。

Answer 1

第1步：创建一个数组（或ArrayList）并将字体添加到其中。

第2步：创建一个变量，跟踪数组的哪个索引包含当前字体。

第3步：每当您想要更改正在使用的字体时，都会增加该变量。

在Processing中循环遍历变量数组
