Prefabs Overview

Prefab is high level object that represents set of render and SDK features.

Prefabs divided on several types:

• On Face - prefabs that depends on face.
• Makeup - represents makeup features. Also depends on face.
• Top Level - affects the whole screen and do not attached to any face.
• Sprites - represents simple 2d sprites
• Sounds - represents audio

Scheme of using prefabs:

{
    "scene": "effect name",
    "version": "2.0.0",

    "camera": {},
    // Top level prefabs
    "background": {
        // ...
    },
    "foreground": {
        // ...
    },
    "lut": {
        // ...
    },
    "lights": {
        // ...
    },
    // On Face
    "faces": [
        {
            // first face
            "face_prefab1": {
                //...
            },
            "makeup_prefab1": {
                //...
            }
            // ...
        },
        {
            // second face
        }
        // ..
    ],
    // Sounds
    "sounds": [
        {
            "sound_prefab1": {
                //...
            },
            "sound_prefab2": {
                //...
            }
            // ...
        }
    ],
    // Sprites
    "sprites": [
        {
            "sprite_prefab1": {
                //...
            },
            "sprite_prefab2": {
                //...
            }
            // ...
        }
        // ...
    ]
}

Where

• scene - this is the name of your effect.
• version - version of this configuration file. Always set it to "2.0.0". Previous version is designed for complex legacy effects.
• camera - tells that you will render camera feed on the screen.
• faces - array of JSON objects describing features you wish to place on each face. So, for each face we will define a JSON object where keys are the names of prefabs and values are the parameters for each prefab.
• top_level_prefab - one of the top level prefabs
• sprites - array of JSON objects describing sprites features.
• sounds - array of JSON objects describing sounds features

tip

You can create effect with any set of prefabs.

tip

You could change effect in runtime calling reload_config()/reloadConfig() method:

C++

    constexpr auto new_config = R"(
        {
            "camera" : {},
                "background" : {
                // ...
            }
        }
    )";
    effect_player->effect_manager()->reload_config(new_config);

Java

import com.banuba.sdk.player.Player

    // ...

    val newConfig =
    """
    {
        "camera" : {},
            "background" : {
            // ...
        }
    }
    """;
    player.effectPlayer.effectManager()
        .reloadConfig(newConfig)

Swift

import BanubaEffectPlayer

// ...
let newConfig = """
{
  "camera": {},
  "background": {
      // ...
  }
}
""";
player.effectPlayer?.effectManager().reloadConfig(newConfig)

JavaScript

const new_config = 
`{
    "camera": {},
    "background": {
      // ...
    }
}`
player._effectManager.reloadConfig(new_config)

note

Colors are represented as 3- or 4-component string, each component is a value in range [0, 1] or [0, 255] separated by a space. E.g.: "1 0 0 1" - red color, etc. HTML-like hex strings are also accepted. E.g.: "#00FF00" - green color, alpha FF is assumed if missing.
