Curve2D

Inherits: Resource < RefCounted < Object

Describes a Bézier curve in 2D space.

Description

This class describes a Bézier curve in 2D space. It is mainly used to give a shape to a Path2D, but can be manually sampled for other purposes.

It keeps a cache of precalculated points along the curve, to speed up further calculations.

Property Descriptions

float bake_interval = 5.0

  • void set_bake_interval ( float value )

  • float get_bake_interval ( )

The distance in pixels between two adjacent cached points. Changing it forces the cache to be recomputed the next time the get_baked_points or get_baked_length function is called. The smaller the distance, the more points in the cache and the more memory it will consume, so use with care.


int point_count = 0

  • void set_point_count ( int value )

  • int get_point_count ( )

The number of points describing the curve.


Method Descriptions

void add_point ( Vector2 position, Vector2 in=Vector2(0, 0), Vector2 out=Vector2(0, 0), int index=-1 )

Adds a point with the specified position relative to the curve's own position, with control points in and out. Appends the new point at the end of the point list.

If index is given, the new point is inserted before the existing point identified by index
