Song Trigger
Song Trigger
Go to the Triggers tab and place down the Song trigger. It lets you add new songs to your level. When selected, click on Edit Object to edit its properties.
The image to the right shows the first page of the Song trigger. Here, there's a volume slider to adjust the gain of the song track, the speed of the song, and the channel.
There is also a checkbox to loop the song, which repeats itself back to the beginning of the song when it reaches the end of the track.
Prep attempts to read the song before it even plays, while Load Prep loads the song and plays it for you, assuming you assign it to the same channel.
Update 2.207 added a new checkbox here as well. Enable Don't Reset if you want the song to continue playing independently of when the player dies.
Speaking of channels: In music production, part of mixing audio is linking audio to effect tracks, or audio channels. You typically want to have each song or sound separate from their channels, unless if they are similar to each other (i.e. all drums go in one channel, whereas ambiance or pads belong in another channel).
The image to the right shows a visualization of effect tracks, or as GD calls it “Channels”.
Let's pick a song. Click on the “Select Custom Song” button.
From here you are able to select a song ID from Newgrounds’ API, or select a wide variety of selected songs that Robtop has made in a music library. You can also click on “Saved” to view any previously downloaded Song IDs to use.
Once you pick a song, head onto the next page by clicking on the arrows next to the main UI.
This is the second page of the Song trigger, and it has these features:
The Start slider allows you to start from any timestamp in the song, and vice versa for the End slider.
Note that the values are in milliseconds, so 1 second is actually 1000 in value, 2 seconds = 2000, and so on.
The FadeIn slider gives values of how much the song goes from no volume to its actual volume gain (Volume Slider), and vice versa for the FadeOut slider.
Edit Song Trigger
Edit Song Trigger
The Edit Song trigger lets you change the properties of an existing song in your level. When selected, click on the Edit Object button to bring up the page on the right.
As mentioned prior, the channels are the target of the effect track that is being affected by every song. (i.e. if your song is in channel 1, you want to target channel 1 to take effect).
The Duration slider is the time it takes to edit the property of the song (Volume or Speed). Think of this as the “Move Time” in a Move trigger or the “Fade time” in the alpha trigger. Alongside the duration slider, you got two checkboxes:
Stop: Abruptly stops the song in the channel.
Stop Loop: Ends the loop of the song played in the channel, assuming that Loop is enabled in the song trigger.
The Speed slider changes the velocity of the song that is played in the channel. Next to the slider is the Change Speed checkbox. This needs to be enabled in order for the speed change to take effect. Note that: 12 Speed = 150% Speed, -12 Speed = 50% Speed.
Below is the formula for the velocity of the speed:
s = 2^(t/12)
t = the speed set to the slider
Below is the formula for the time it takes when applying its speed slider:
n+(2^t/12)(x-n)
n = start offset
x = end offset
Also worth mentioning that each speed increments and decrements per semitone. 12 semitones = 1 octave. (This will later be talked about when we cover pitches in the SFX trigger).
The Volume slider adjusts the gain (or volume) of the channel that is being played. Next to the slider is the Change Volume button. This needs to be enabled in order for the volume to take effect.
As before, click on either arrow from the main UI to go to the next page of the Edit Song Trigger.
This entire page deals with proximity based on the player, camera, or object. Proximity in music is adjusting volume gain based off of the distance relative to an object or player. The farther away the target is to the object, the less of an effect it'll create. The closer it is, the more effect it'll create.
Group ID 1 is the target object that will be used when calculating the proximity.
Group ID 2 (when applying proximity with Group ID 1) is the object that will be applied to the object.
In the left set of sliders, you can adjust the volume for whatever distance you set it to:
VolNear: Volume in a near distance. This creates a red area when selecting the song trigger.
VolMed: Volume in a range of distances between Near and Far. This creates a green area when selecting the song trigger.
VolFar: Volume in a far distance. This creates a blue area when selecting the song trigger.
In the right set of sliders, you can adjust the distance of VolNear, VolMed, and VolFar in their own respective sliders labeled MinDist, Dist2, and Dist3. Adjusting these sliders will also move the colored areas accordingly.
Note that these colored lines represent a visualization of proximity.
On the bottom left, you can select either P1, P2, and/or Camera to be the replacement for Group ID 2.
On the bottom right, you can select different modes for proximity. Each button shows arrows facing which way will the proximity take effect, while the line represents the object that is being targeted. (Group ID 1).
This video demonstrates a good usage of the song and song edit triggers.
