JSON Script Attributes Preview

We have levelled up the Script Attributes that makes it much easier to organize and group related attributes together.

Using JSON, developers are able to define a schema for a data object that has multiple attributes and have them grouped together in the Inspector.

In the example below, we have created a JSON schema with the name ‘settings’ and has the attributes ‘gravity’, ‘startingHealth’ and ‘godMode’.

GameManager.attributes.add('settings', {
    type: 'json',
    schema: [{
        name: 'gravity',
        type: 'number',
        default: -9.8
    }, {
        name: 'startingHealth',
        type: 'number',
        default: 20
    }, {
        name: 'godMode',
        type: 'boolean',
        default: false

In the Inspector, the data object is shown as a collapsible section:

Collapsible script settings

Even better, these data objects can made into an array! This is a huge improvement over having to organize multiple attribute arrays that was difficult to update and error prone to maintain.

Example JSON schema for an array of enemies:

GameManager.attributes.add('enemies', {
    type: 'json',
    schema: [{
        name: 'health',
        type: 'number',
        default: 10
    }, {
        name: 'type',
        type: 'number',
        enum: [
            { 'Close Combat': 1 },
            { 'Range': 2 },
            { 'Both': 3 }
    }, {
        name: 'templateAsset',
        type: 'asset',
        assetType: 'template'
    array: true

Becomes the following in the inspector which is so much cleaner!
