Transform | Delightex API

Defines the position, scale and rotation of an item.

Every Transform can be assigned to a BaseItem.parent which allows hierarchical editing of their position, scale and rotation. Created hierarchies are displayed in the Item Hierarchy tab.

constructor

new Transform(): Transform

Inherited from ReadonlyTransform.constructor
Returns Transform

Properties

Readonly axisX

axisX: Vector3

Red axis of this Transform.

Readonly axisY

axisY: Vector3

Green axis of this Transform.

Readonly axisZ

axisZ: Vector3

Blue axis of this Transform.

Readonly forward

forward: Vector3

Shorthand for Y - axis.

Note: By default, DX Engine uses the green Y axis as forward vector.

position

position: Vector3

Position of this Transform using X, Y, and Z coordinates.

Note: By default, DX engine uses Z for "up".

Readonly right

right: Vector3

Shorthand for X - axis.

Note: By default, DX Engine uses the red X axis as right vector.

rotation

rotation: Quat

Rotation of this Transform stored as Quat.

scale

scale: number

Scale of this Transform.

Default value is 1.

Readonly up

up: Vector3

Shorthand for Z - axis.

Note: By default, DX Engine uses the Z axis as up vector.

lookAt

lookAt(target: Vector3, upDirection: Vector3): Transform
lookAt(target: Vector3): Transform

- Defined in api.ts:2798

  point to look at.
- upDirection: Vector3
  
  upward direction.
Returns Transform
- Defined in api.ts:2807
Rotates this Transform so that the forward vector points to the target.

Note: By default, DX engine uses Y axis as forward vector.

Parameters
- target: Vector3
  
  point to look at.
Returns Transform

multScale

multScale(scaleFactor: number): Transform

- Defined in api.ts:2890
Multiplies this Transform current scale by scale

Parameters
- scaleFactor: number
Returns Transform

rotate

rotate(origin: Vector3, axis: Vector3, angleInRadians: number): Transform
rotate(axis: Vector3, angleInRadians: number): Transform

- Defined in api.ts:2840

Parameters
- origin: Vector3
  
  world space position to rotate around.
- axis: Vector3
  
  rotation axis.
- angleInRadians: number
  
  rotation in radians.
Returns Transform
- Defined in api.ts:2849
Rotates this Transform by angleInRadians around world position (0,0,0) towards axis direction.

Parameters
- axis: Vector3
  
  rotation axis.
- angleInRadians: number
  
  rotation in radians.
Returns Transform

rotateLocal

rotateLocal(offset: Vector3, axis: Vector3, angleInRadians: number): Transform
rotateLocal(axis: Vector3, angleInRadians: number): Transform

- Defined in api.ts:2860

Parameters
- offset: Vector3
  
  offset relative to current position.
- axis: Vector3
  
  rotation axis.
- angleInRadians: number
  
  rotation in radians.
Returns Transform
- Defined in api.ts:2869
Rotates this Transform by angleInRadians around its pivot towards axis direction.

Parameters
- axis: Vector3
  
  rotation axis.
- angleInRadians: number
  
  rotation in radians.
Returns Transform

set

set(transform: ReadonlyTransform): Transform

- Defined in api.ts:2787

Parameters
- transform: ReadonlyTransform
  
  Transform to copy values from.
Returns Transform

setDirection

setDirection(direction: Vector3, upDirection: Vector3): Transform
setDirection(direction: Vector3): Transform

- Defined in api.ts:2821
Rotates this Transform so that
- its local Y-axis points towards the defined direction.
- its local Z-axis points towards the worldUp direction.
Note: The local Z-axis always attempts to be perpendicular to Y, which may lead to worldUp not always accurately pointed at.
