Print#
The Print block is used to print values or text in the Print Console or EXP Brain’s screen.
All reporter blocks will be printed as integer (whole) numbers by default. Use the Set print precision block to adjust the number of decimal places printed.
All new projects begin with the screen cursor at row 1 column 1, and at row 1 on the Print Console.
By default, the Print block will remain on the same row for any subsequent print commands. By expanding the Print block to show and set cursor to next row, this will move the cursor to the next row after printing.
Important: The Print block will not print anything to the Brain screen unless it is expanded to and set cursor to next row or followed by a Next Row block.
Any block that returns a value can be used in the Print block.
Choose which device to use.
In this example, the robot’s current rotation will be printed to the EXP Brain.
Set Cursor#
The Set Cursor block is used to set the cursor location for Print blocks on the EXP Brain’s screen.
The Set Cursor block accepts a range for row of 1 to 5 and a range for column of 1 to 16.
In this example, the robot will print the current timer value on the Brain, clear the value, and reset back to the first column and row before printing again.
Next Row#
The Next Row block is used to set the print output cursor on the Print Console or EXP Brain’s screen to the next available row.
By default, all projects begin with the screen cursor at row 1 column 1. The Next Row block will move the cursor down by a single row on the screen. The Next Row block will also set the cursor’s column to position 1.
In this example, the robot will print “Hello” on the 1st row and “world!” on the 2nd row.
Set print precision#
The Set print precision block is used to set the number of digits that appear after the decimal point when printing reporter blocks on the Print Console or EXP Brain’s screen.
Choose the level of precision that inserted reporter blocks will be printed to the screen.
Ones (1) (Default)
Tenths (0.1)
Hundredths (0.01)
Thousandths (0.001)
All Digits (0.000001)
Choose which device to use.
In this example, the print precision is set to hundredths before printing the current drivetrain heading.
Clear All Rows#
The Clear All Rows block is used to clear the entire Print Console or EXP Brain’s screen.
In this example, the robot will print the current timer value on the Brain, clear the value, and reset back to the first column and row before printing again.
Clear Row#
The Clear Row block is used to clear a single row on the EXP Brain’s screen.
In this example, the robot will print “VEXcode” on three different rows before deleting the “VEXcode” in the 2nd row.
