class Projector3d (client-side)

Available since version: 0.3.4

This class represents 3d projector, that can be used to display 2d elements in 3d worlds via simple projection.

Constructor

Projector3d(float x, float y, float z, float distance)

Parameters:

• float x: the position in the world on the x axis.
• float y: the position in the world on the y axis.
• float z: the position in the world on the z axis.
• float distance: the maximum visible distance in the world.

Properties

Vec3& position

Represents the 3d position on the world for projector 3d.

This callback is being executed when projector visibility gets changed.

void onVisibilityChange(bool visible)

Parameters:

• bool visible: the current visibility state.

---

onUpdate

This callback is being executed each frame when 3d projection is visible, use it to implement your custom update logic.

Parameters:

• Vec2i screenPositionPx: the calculated screen position in pixels.
• float deltaDistance: the current 3d distance between 3d projected position and player.
