# pause Until
|
|
|
|
Causes your program to wait until an event at a button happens.
|
|
|
|
```sig
|
|
brick.buttonEnter.pauseUntil(ButtonEvent.Click);
|
|
```
|
|
|
|
## Parameters
|
|
|
|
* **ev**: the button action to wait for. The button actions (events) are:
|
|
> * ``click``: button was clicked (pressed and released)
|
|
> * ``up``: button is released from just being pressed
|
|
> * ``down``: button is just pressed down
|
|
|
|
## Example
|
|
|
|
Wait for the `up` button to go up before continuing with displaying a message on the screen.
|
|
|
|
```blocks
|
|
let waitTime = 0;
|
|
brick.showString("We're going to wait", 1);
|
|
brick.showString("for you to press and", 2);
|
|
brick.showString("release the UP button", 3);
|
|
waitTime = control.millis();
|
|
brick.buttonUp.pauseUntil(ButtonEvent.Click);
|
|
brick.clearScreen();
|
|
if (control.millis() - waitTime > 5000) {
|
|
brick.showString("Ok, that took awhile!", 1)
|
|
} else {
|
|
brick.showString("Ah, you let go!", 1)
|
|
}
|
|
```
