打印控制台#

打印控制台命令仅在使用 VEXcode EXP 时可用。如果您在 VS Code 中编码，则需要使用 Brain.Screen 命令打印到 EXP 的 Brain Screen。

所有新项目都从打印控制台中的第 1 行光标开始。

命令 #

The printf(text) method prints text on the screen using the current cursor position.

参数	描述
文本	要打印到打印控制台的字符串（在引号中）或整数。

打印到打印控制台的值可以使用格式说明符来显示打印语句内的值。

此示例将 V5 Brain 的当前时间打印为具有 2 位小数的浮点数。

printf("Screen Pressed? %s\n", Brain.Screen.pressing());

格式说明符还可以包含标志以进一步修改它们：

%6f - This prints a floating point number that is a minimum of 6 characters wide.
%.2f - This prints a floating point number with 2 decimal places.
%6.2f - This prints a floating point number that is a minimum of 6 characters wide with 2 decimal places.

/n is a newline character, and it is required by the printf command to output any of its contents to the Print Console.

printf("This text will be ");
printf("printed on the same line\n");
printf("This is on a new line\n");

您可以使用以下颜色代码更改打印到打印控制台时文本的颜色：

All color codes need to be attached to an escape sequence = \033 in order to function.

You can either use this directly in a print command with a string.

// Print VEXcode in Red to the Print Console.
printf("\033[31m VEXcode\n");

Or, you can use it on its own to set all print commands afterwards to the set color.

// Set the Print Console text color to Red before printing VEXcode.
printf("\033[31m");
printf("VEXcode\n");

**返回：**无。

By using \033[2J\n inside of the printf command, you can clear the entire Print Console. This will also set the cursor back to row 1.

下面的示例将打印“VEXcode”，然后在 2 秒后清除打印控制台。

printf("VEXcode\n");
wait(2, seconds);
printf("\033[2J\n");
