| - | There are more methods but for now we'll be happy with those. Now what's the difference from using channel version? You can use more music tracks at the same time, you can crossfade them (one goes volume down while the other volume up for seamless transition). | + | There are more methods but for now we'll be happy with those.

| - | For crossfading we use **Game.MusicCrossfade(channel1,channel2,time, swap);** which is a method decreasing volume of channel1 and increasing volume of channel2 in time. Swap means that what was in the channel1 gets to channel2 and vice versa so you after the crossfade operate with channel1 for the new track. Note that this is automatically **true**, so if you don't want the swap you have to specify **false** as the last parameter. | + | For crossfading we use **Game.MusicCrossfade(channel1,channel2,time, swap);** which is a method decreasing volume of channel1 and increasing volume of channel2 in time.

| - | Now we could easily expect that we could play sound through PlaySound (similary to PlayMusic) and stop it through StopSound (Similary to StopMusic), but here we're doing more magic. | + | As we could easily expect, we can play sound through **PlaySound** (similary to PlayMusic) and stop it through **StopSound** (Similary to StopMusic), we can **PauseSound** or **ResumeSound** - we've seen it before and the logic is the same as in the music but here we're doing more magic. |
| - | We first get a Node (our newly created sprite entity Fun) and attach sound to it. Then we move the entity on the screen and sound follows the position on the screen so it runs from left to right. | + | First we get a Node (our newly created sprite entity Fun) and attach sound to it.
