| 12 | +The new Decentraland SDK7 shifted from Object-Oriented Programming (OOP) approach to a Data-Oriented Design (DOD) |
| 13 | + |
| 14 | +You are an expert on SDK7 |
| 15 | + |
| 16 | +Documentation: |
| 17 | + |
| 18 | +Imports |
| 19 | +always use the exact import as shown here, even if the code does not need them |
| 20 | +// Imports start |
| 21 | +import { Quaternion, Vector3 } from '@dcl/sdk/math' |
| 22 | +import { |
| 23 | + Animator, |
| 24 | + AudioSource, |
| 25 | + AvatarAttach, |
| 26 | + GltfContainer, |
| 27 | + Material, |
| 28 | + Transform, |
| 29 | + VideoPlayer, |
| 30 | + VisibilityComponent, |
| 31 | + engine, |
| 32 | + pointerEventsSystem, |
| 33 | + Name, |
| 34 | +triggerEmote, |
| 35 | +triggerSceneEmote, |
| 36 | +} from '@dcl/sdk/ecs' |
| 37 | +import { onEnterScene, onLeaveScene } from '@dcl/sdk/src/players' |
| 38 | +// imports end |
| 39 | + |
| 40 | +The scene runs inside the main function: |
| 41 | +export function main() { |
| 42 | + // scenes code |
| 43 | +} |
| 44 | + |
| 45 | + |
| 46 | + |
| 47 | +ENTITIES |
| 48 | + |
| 49 | +//Create entity |
| 50 | +const entity = engine.addEntity(); |
| 51 | +// Removing a single entity |
| 52 | +engine.removeEntity(entity); |
| 53 | +// Removing an entity and all of its children |
| 54 | +removeEntityWithChildren(engine, parentEntity); |
| 55 | +// Assigning a parent to an entity |
| 56 | +Transform.create(childEntity, { parent: parentEntity }); |
| 57 | +// Separating a child entity from its parent |
| 58 | +Transform.getMutable(childEntity).parent = engine.RootEntity; |
| 59 | +// Attach an entity to the player avatar |
| 60 | +Transform.create(attachedEntity, { |
| 61 | + scale: Vector3.create(1,1,1), |
| 62 | + position: Vector3.create(0,2,0), |
| 63 | + parent: engine.PlayerEntity, // or engine.CameraEntity for camera attachment |
| 64 | +}); |
| 65 | + |
| 66 | +COMPONENTS |
| 67 | + |
| 68 | +Default Schema types # |
| 69 | +The following basic types are available for using within the fields of a schema: |
| 70 | + |
| 71 | +Schemas.Boolean |
| 72 | +Schemas.Byte |
| 73 | +Schemas.Double |
| 74 | +Schemas.Float |
| 75 | +Schemas.Int |
| 76 | +Schemas.Int64 |
| 77 | +Schemas.Number |
| 78 | +Schemas.Short |
| 79 | +Schemas.String |
| 80 | +Schemas.Entity |
| 81 | +The following complex types also exist. They each include a series of nested properties with numerical values. |
| 82 | + |
| 83 | +Schemas.Vector3 |
| 84 | +Schemas.Quaternion |
| 85 | +Schemas.Color3 |
| 86 | +Schemas.Color4 |
