## Separate tasks #tasks
|
|
|
|
As an example, you could have a small task that checks the battery level and gives a warning when it drops below 15 percent. This is placed inside a ``||control:run in parallel||`` block:
|
|
|
|
```block
|
|
let powerCheck = false;
|
|
|
|
control.runInParallel(() => {
|
|
while (!powerCheck) {
|
|
if (brick.batteryLevel() <= 15) {
|
|
brick.setStatusLight(StatusLight.RedFlash)
|
|
powerCheck = true;
|
|
} else {
|
|
pause(5000);
|
|
}
|
|
}
|
|
})
|
|
```
|
|
|
|
The code the main program just drives the brick in a constant pattern until the battery check in the parallel task says that the battery level is too low.
|
|
|
|
```block
|
|
let powerCheck = false;
|
|
while (!powerCheck) {
|
|
motors.largeBC.tank(50, 50, 5, MoveUnit.Seconds)
|
|
motors.largeBC.steer(5, 50, 6, MoveUnit.Rotations)
|
|
}
|
|
motors.stopAll()
|
|
```
|
|
|
|
## #example
|
|
|
|
Tank the brick in a pattern until the battery warning variable is set. Have a separate task check the battery level and set a warning variable when the level is below `5` percent.
|
|
|
|
```blocks
|
|
let powerCheck = false;
|
|
|
|
control.runInParallel(() => {
|
|
while (!powerCheck) {
|
|
if (brick.batteryLevel() < 5) {
|
|
powerCheck = true;
|
|
} else {
|
|
pause(5000);
|
|
}
|
|
}
|
|
})
|
|
|
|
while (!powerCheck) {
|
|
motors.largeBC.tank(20, 20, 5, MoveUnit.Seconds)
|
|
motors.largeBC.steer(15, 20, 6, MoveUnit.Rotations)
|
|
motors.largeBC.tank(40, 40, 5, MoveUnit.Seconds)
|
|
motors.largeBC.steer(-10, 20, 3, MoveUnit.Rotations)
|
|
}
|
|
motors.stopAll()
|
|
```
