PathFollow3D

Hereda: Node3D < Node < Object

Una muestra de puntos para un Path3D.

Descripción

This node takes its parent Path3D, and returns the coordinates of a point within it, given a distance from the first vertex.

It is useful for making other nodes follow a path, without coding the movement pattern. For that, the nodes must be children of this node. The descendant nodes will then move accordingly when setting the progress in this node.

Enumeraciones

enum RotationMode: 🔗

RotationMode ROTATION_NONE = 0

Prohíbe que PathFollow3D rote.

RotationMode ROTATION_Y = 1

Permite que PathFollow3D rote sólo en el eje Y.

RotationMode ROTATION_XY = 2

Permite que PathFollow3D rote en los ejes X e Y.

RotationMode ROTATION_XYZ = 3

Permite que PathFollow3D rote en cualquier eje.

RotationMode ROTATION_ORIENTED = 4

Uses the up vector information in a Curve3D to enforce orientation. This rotation mode requires the Path3D's Curve3D.up_vector_enabled property to be set to true.

bool cubic_interp = true 🔗

  • void set_cubic_interpolation(value: bool)

  • bool get_cubic_interpolation()

If true, the position between two cached points is interpolated cubically, and linearly otherwise.

The points along the Curve3D of the Path3D are precomputed before use, for faster calculations. The point at the requested offset is then calculated interpolating between two adjacent cached points. This may present a problem if the curve makes sharp turns, as the cached points may not follow the curve closely enough.

There are two answers to this problem: either increase the number of cached points and increase memory consumption, or make a cubic interpolation between two points at the cost of (slightly) slower calculations.

float h_offset = 0.0 🔗

  • void set_h_offset(value: float)

  • float get_h_offset()

El nodo está desplazado a lo largo de la curva.

bool loop = true 🔗

  • void set_loop(value: bool)

  • bool has_loop()

Si es true, cualquier desplazamiento fuera de la longitud del camino se envolverá, en lugar de detenerse en los extremos. Úsalo para los caminos cíclicos.

float progress = 0.0 🔗

  • void set_progress(value: float)

  • float get_progress()

The distance from the first vertex, measured in 3D units along the path. Changing this value sets this node's position to a point within the path.

float progress_ratio = 0.0 🔗

  • void set_progress_ratio(value: float)

  • float get_progress_ratio()

The distance from the first vertex, considering 0.0 as the first vertex and 1.0 as the last. This is just another way of expressing the progress within the path, as the progress supplied is multiplied internally by the path's length.

It can be set or get only if the PathFollow3D is the child of a Path3D which is part of the scene tree, and that this Path3D has a Curve3D with a non-zero length. Otherwise, trying to set this field will print an error, and getting this field will return 0.0.

RotationMode rotation_mode = 3 🔗

Permite o prohíbe la rotación en uno o más ejes, dependiendo de las constantes RotationMode que se utilicen.

bool tilt_enabled = true 🔗

  • void set_tilt_enabled(value: bool)

  • bool is_tilt_enabled()

If true, the tilt property of Curve3D takes effect.

bool use_model_front = false 🔗

  • void set_use_model_front(value: bool)

  • bool is_using_model_front()

If true, the node moves on the travel path with orienting the +Z axis as forward. See also Vector3.FORWARD and Vector3.MODEL_FRONT.

float v_offset = 0.0 🔗

  • void set_v_offset(value: float)

  • float get_v_offset()

El nodo está desplazado perpendicularmente a la curva.

Transform3D correct_posture(transform: Transform3D, rotation_mode: RotationMode) static 🔗

Correct the transform. rotation_mode implicitly specifies how posture (forward, up and sideway direction) is calculated.
