pressing() → bool[source]

Return Button’s pressed status.

VEXCODE PYTHON:

Reports if the specified button on the VEX IQ Brain is being pressed.

Reports True if the specified Brain button is pressed. Reports False if the specified Brain button is not pressed.

After brain. enter a Brain button to receive the pressed status on.

Supported Brain buttons are as follows: - buttonUp / buttonLeft - buttonDown / buttonRight - buttonCheck

ROBOT MESH PYTHON B:

Get the pressed status of a button.

Returns: True if pressed, False otherwise.

clear_screen()[source]

Clear Brain LCD Screen.

VEXCODE PYTHON:

Clears the entire VEX IQ Brain’s Screen.

Clear Screen will not reset the Brain’s screen cursor.

Use the Set Cursor command to set the Brain’s cursor to the desired position.

ROBOT MESH PYTHON B:

Clear the whole screen.

print_line(number: int, text: str)[source]

Print to a line on Brain LCD Screen.

ROBOT MESH PYTHON B:

Print a number, string, or boolean at a particular line.

(clearing the rest of the line)

Parameters number: Line to print on, 1 is top line. text: object to print, usually a string.

Use “” to clear the line. For multiple arguments, use format like “x: %g y: %g” % (x, y) -> “x: 123 y: 456” Supported format flags are g (all) x (hex) d (int) f (float)
