# Touching Edge
|
||
|
|
|
||
|
|
Find whether the sprite is touching the edge of the [LED screen](/device/screen).
|
||
|
|
|
||
|
|
Sprites are touching the edge if they overlap with an LED on the edge
|
||
|
|
of the screen.
|
||
|
|
|
||
|
|
```sig
|
||
|
|
let item: game.LedSprite = null;
|
||
|
|
item.isTouchingEdge();
|
||
|
|
```
|
||
|
|
|
||
|
|
### Parameters
|
||
|
|
|
||
|
|
* a **sprite** that might be touching the edge of the screen
|
||
|
|
|
||
|
|
### Returns
|
||
|
|
|
||
|
|
`true` if the sprite is touching the edge of the screen
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
This program makes a sprite in the middle of the left edge of the LED screen.
|
||
|
|
Then it says `EDGY!` if it's on the edge (which it is!), and `SAFE!` if it's
|
||
|
|
not on the edge.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
let item = game.createSprite(0, 2);
|
||
|
|
if (item.isTouchingEdge()) {
|
||
|
|
basic.showString("EDGY!");
|
||
|
|
} else {
|
||
|
|
basic.showString("SAFE!");
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
