Entity properties

Logic

components

Defines components and the order in which they are initialized.

"components": [
    list of components
]

Example:

"components": [
    "base:drop"
]

You can pass values ​​in ARGS from the entity configuration. They will be passed both when creating a new entity and when loading a saved one. The args list is used for this:

"components": [
    {
        "name": "base:drop",
        "args": {
            "item": "base:stone.item",
            "count": 1
        }
    }
]

The components code should be in scripts/components.

Physics

hitbox

An array of three numbers indicating the size of the entity's hitbox.

Example:

"hitbox": [0.6, 1.8, 0.6]

body-type

Determines how the physics engine will work with it.

• static - static body. No physics calculation, no velocity.
• dynamic - default type. The physics engine calculates movement and collisions.
• kinematic - only movement is calculated, without collisions.

blocking

Determines whether the entity blocks installation of blocks.

In the future will also block other entities movement.

Default value: true.

sensors

A sensor is an area attached to a physical body that detects the entry of other bodies into it.

• When a body enter, the on_sensor_enter event is triggered.
• When a body exit, the on_sensor_exit event is called.

Sensors are indexed in the same order as they are presented in the list, starting from 0.

The following types (shapes) of sensors exist:

• radius is the simplest sensor. Defines the area around the center of the hitbox. The following values ​​are specified:
  • radius - number.
• aabb - a rectangular area that changes position depending on the rotation of the entity. The area itself does not rotate. The following values ​​are specified:
  • three numbers x, y, z of the minimal corner of the area.
  • three numbers x, y, z of the opposite corner of the area.

Example:

"sensors": [
    ["aabb", -0.2, -0.2, -0.2, 0.2, 0.2, 0.2],
    ["radius", 1.6]
]

0. A rectangular area with a width, height and length of 0.4 m, centered at 0.0.
1. Radial area with a radius of 1.6 m.

solid

Makes the entity's hitbox an obstacle. When enabling this property for dynamic body, a mass must be specified.

mass

Defines the entity's mass. Kilograms are used as the default. For kinematic bodies, an infinite mass is used instead.

elasticity

Defines the entity's elasticity (affects the bounce on collision).

step-height

Defines the maximum height of an obstacle an entity can step onto without jumping.

material

Defines the entity's material (same as for blocks).

View

skeleton-name

The default value is the same as the entity name. Determines which skeleton will be used by the entity. See rigging.

Saving/Loading

In addition to custom components, the engine automatically saves data from the built-in ones: transform, rigidbody, skeleton.

There is a set of flags that allow you to specify which data will be saved and which will not.

(Boolean values ​​are specified)

Title	Target	Default
save	the entity itself	true
save-skeleton-pose	skeleton pose	false
save-skeleton-textures	dynamically assigned textures	false
save-body-velocity	body velocity	true
save-body-settings	changed body settings (type, damping, crouching)	false
