Html5 audio events code#
Since there are no numbers of code lines, you should be looking somewhere at 60% mark of his code. Let’s take a quick look at David’s listener code. However, to fully understand the concept of audio tracking, I recommend doing both: reading this article and watching the tutorial. If you prefer video tutorials instead, you can watch a video here.
Html5 audio events how to#
How to track HTML5 audio player with Google Tag Manager: Final words.Custom Event Trigger and Data Layer Variables Create a trigger that activates the listener only when the audio player is present So how do we actually track HTML5 audio player with GTM?.
If you want to get familiar with event tracking in Google Analytics 4, you can also refer to this blog post. Note: this blog post teaches how to track events with Universal Analytics. You can also find a GTM recipe here.īut today’s blog post is not about the video. Yes, I’m talking about David Vallejo’s HTML5 video listener that is used to track almost any other video player that is not Youtube or Vimeo (or anything else in the iFrame). Even this Twitter (that I saw today in my feed) confirmed this: Note that this event will be triggered on all platforms, but on everything except HTML5 it will only be triggered once on Game Start when the audio engine is first initialised.Updated: November 15th. I guess that the majority of the GTM community is familiar with a custom event listener that probably already has the status of legendary. When this key exists, there will also be a further " status" key which will be either " available" or " unavailable". In this event you will get the built in async_load DS map populated with the key " event_type" which in turn will hold the string " audio_system_status" if it is an audio event. You may also use the Asynchronous System Event, which will be triggered whenever the Web Audio status changes. To help with this issue, GameMaker has two separate ways to detect the change in Web Audio context status, either using the following function: What causes this varies greatly between browsers, and even between different versions of the same browser, and so detecting when the web audio context status changes is very important, e.g.: to detect when the context changes and pause/start looping audio like background music. This is because the Web Audio context may not be running or may stop running when your game is being played. When creating games for the HTML5 target platform, the audio engine requires Web Audio support, and this in turn means that sometimes your audio won't play when or how you expect it.
As such it is recommended that you have a good working knowledge of how the rest of the GameMaker audio engine works before using any of the following functions:įurther advanced functionality, like setting listeners, recording audio, or synchronising multiple audio tracks over time can all be found from the sub-sections listed below: The following functions are designed to give more control over how the audio engine works, and how the sounds played through it will be "heard" by the listener. The following functions are for dealing with audio in the most straightforward and simple way possible, avoiding the use of emitters and permitting the user to generate sounds and play music easily as these sounds are always generated at the listener position (see the section linked below for more details on the listener) and so are generally not affected by any changes to the listener: You can get a general idea of Web Audio support from the following link: Can I Use Web Audio?. IMPORTANT! When using audio on the HTML5 target, you should be aware that not all browsers support Web Audio and so may not play any sound for your project when run. There are also a selection of more specialised functions dedicated to streaming audio, positioning audio - to give 3D sound - and grouping audio. For things more complex than basic sound effects or playing a single piece of music you can refer to the advanced audio functions which let you modify how a sound is played. Sounds of these types added to the IDE can then be used in your game using the basic audio functions shown below. GameMaker has a complete audio engine that is based on the *.ogg, *.mp3 and *.wav sound formats.
