Assets preloading (preload.json file)

preload.json in content-pack folder is used for specifying additional assets should be loaded, like sounds.

The file contains following categories available:

• animation
• fonts
• models
• shaders
• skeletons
• sounds
• textures

Note

Sound loading with all variations following template: (sound: sound_name) -> sound_name.ogg, sound_name_1.ogg, sound_name_2.ogg, ... or sound_name_0.ogg, sound_name_1.ogg, sound_name_2.ogg, ...

Adding sound packid:sounds/events/explosion.ogg with all variants example:

{
	"sounds": [
		"events/explosion"
	]
}

Sound will be available as "events/explosion"

{
    "sounds": [
        {
            "name": "events/explosion",
            "keep-pcm": true
        }
    ]
}
