First off, you want to start by opening your level editor. The advanced level editor can be found here https://www.plazmaburst2.com/level_editor/map_edit.php#.
Make sure to open the correct map. Next, you want to find a button that looks like this:
Once you find this button, click it, then click anywhere on your map to place a music or song mark. These are what allow you to play songs.
After you place your music mark, make sure you have a song ready. For this example, we'll be using Newgrounds.
You can find the Newgrounds Audio section here https://www.newgrounds.com/audio/browse. In order to use a song from Newgrounds, it must meet some requirements first:
- 1. The song must have at least 10 votes
2. The song must be under 10 MB (Megabytes)
3. The song must have a rating of 6+ out of 10 or 3+ Stars
4. The song must be downloadable
Once you find a suitable song, copy and paste the URL into the URL box of the music mark, like so:
(The full song URL is https://www.newgrounds.com/audio/listen/85046.
After you add your desired song, you need to create a trigger that will play the song when activated. This trigger action can be found here:
But you need to activate the trigger for the song to play. Activating triggers can be done through a number of methods, including but not limited to:
- 1. Timers
2. Buttons
3. Player Character activated regions
4. Trigger on death
After you activate the trigger, the song will play for a period of time depending on the settings of the music mark. Experiment! Don't forget to have fun with your map designs!
