# Touching

Find whether the sprite is touching another sprite you say.

Sprites are touching if they share the same LED.

```sig
let item: game.LedSprite = null;
item.isTouching(null);
```

### Parameters

* a **sprite** you are checking
* another **sprite** that might be touching the one you are checking

### Returns

`true` if the two sprites are touching.

### Example

This program creates two sprites called ``matter`` and ``antimatter``,
and then checks whether they are touching.  If they are, there is an
explosion.

```blocks
let matter = game.createSprite(2, 2);
let antimatter = game.createSprite(2, 2);
if (matter.isTouching(antimatter)) {
    basic.pause(500);
    basic.clearScreen();
    basic.showString("BOOM!");
}
```
