Methods
add_waveform(_url, _x, _y)
Adds a waveform to the array of waveforms.
Parameters:
| Name | Type | Description |
|---|---|---|
_url |
string | URL of the waveform audio file |
_x |
number | x-coordinate of the waveform |
_y |
number | y-coordinate of the waveform |
draw()
Draws the waveforms.
move()
Moves one of the waveforms.
playback()
Starts the playback of the waveforms.
touch_check()
Checks and stores which waveform is being touched.
touch_end()
Calls touch_end() for an indiviual waveform that was being touched, and
resets the class' movingIdx property to -1 (indicating that no waveform
is being touched).
