Controls

Introduction

The Control blocks in VEXcode AIR manage the flow of a project by handling loops, conditions, delays, and stopping execution. Below is a list of available blocks:

• wait – Pauses execution for a specific duration.

• wait until – Pauses execution until a specified condition is met.

• repeat – Repeats enclosed blocks a specific number of times.

• forever – Repeats enclosed blocks indefinitely.

• repeat until – Repeats enclosed blocks until a condition is met.

• while – Repeats enclosed blocks while a condition remains true.

• if – Runs enclosed blocks if a condition is true.

• if / else – Runs one set of blocks if a condition is true, otherwise runs another.

• if / else if / else – Runs different sets of blocks depending on multiple conditions.

• break – Exits a repeat, forever, repeat until, or while loop immediately.

• stop project – Ends the execution of the project.

wait

The wait block pauses for a specific amount of time before moving to the next block.

wait stack block

    wait (1) seconds

Parameters	Description
time	The amount of time to wait, as a positive integer or decimal in seconds.

Example

Example coming soon!

wait until

The wait until block pauses execution until a specified condition is met before proceeding to the next block.

wait until stack block

    wait until <>

Parameters	Description
condition	The condition that must be met before moving on to the next block.

Example

Example coming soon!

repeat

The repeat block runs the blocks inside it a set number of times.

repeat c block

    repeat [10]
    end

Parameters	Description
times	A whole number that sets how many times the repeat block runs.

Example

Example coming soon!

forever

The forever block keeps running the blocks inside it again and again without stopping.

forever c block

    forever
    end

Parameters	Description
	This block has no parameters.

Example

Example coming soon!

repeat until

The repeat until block executes the enclosed blocks repeatedly while the condition evaluates as False.

repeat until block

    repeat until <>
    end

Parameters	Description
condition	An expression or variable that is evaluated before each iteration. If it evaluates as: False - The loop continues True - The loop stops

Example

Example coming soon!

while

The while block executes the enclosed blocks repeatedly while the condition evaluates as True.

while c block

    while <>
    end

Parameters	Description
condition	An expression or variable that is evaluated before each iteration. If it evaluates as: True - The loop continues False - The loop stops

Example

Example coming soon!

if

The if block executes the enclosed block of code if the condition evaluates as True.

if block

    if <> then
    end

Parameters	Description
condition	An expression or variable that is evaluated when the statement runs. If it evaluates as: True - The code inside the if block executes False - The block is skipped

Example

Example coming soon!

if / else

The if / else block determines which enclosed block of code runs based on whether the condition evaluates as True or False.

if then else block

    if <> then
    else
    end

Parameters	Description
condition	An expression or variable that is evaluated when the statement runs. If it evaluates as: True - The code inside the if block executes False - The code inside the else block executes instead

Example

Example coming soon!

if / else if / else

The if / else if / else block structure selects which enclosed block of code runs based on conditions:

• if runs its block of code if the condition evaluates as True.

• else if checks additional conditions only if all previous conditions evaluated as False. Multiple else if statements can be used.

• else runs its block of code only if none of the previous conditions evaluated as True.

if else if else block

    if <> then
    else if <> then
    else 
    end

Parameters	Description
condition	An expression or variable that is evaluated when the statement runs. The first condition that evaluates as: True - Determines which block of code executes False - If none are True, the else block of code runs

Example

Example coming soon!

break

The break block exits a loop immediately.

break stack block

    break

Parameters	Description
	This block has no parameters.

Example

stop project

The stop project block ends a running project.

stop project block

    stop project :: control cap

Parameters	Description
	This block has no parameters.
