Time for action — creating the explosion

The method to emit explosion particles works in a similar way to the one that emits smoke.

Insert a method called SpawnExplosion in the game class. The parameters are the x and y positions, and the amount of particles to create.
```
Method SpawnExplosion:Int(x:Float, y:Float, amount:Int)
```
Set the default layer to the game layer.
```
eng.SetDefaultLayer(layerGame)
```
Start a FOR loop for the local i variable ranging from 1 to the amount parameter of the method.
```
For Local i:Int = 1 To amount
```
Determine a random x offset that is used when an image object for the explosion particle is created.
```
Local xoff:Float = Int(Rnd(0,3))
```
Create a local object for the particle image. It will be placed at the coordinates given to the method.
```
Local obj:=eng.CreateImage(atlas,144+xoff*16.0,80,16,16, x,y)
```
