- cubicInterp
bool cubicInterp [@property getter]
bool cubicInterp [@property setter]
If true the position between two cached points is interpolated cubically, and linearly otherwise.
The points along the Curve2D of the Path2D 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.
- hOffset
double hOffset [@property getter]
double hOffset [@property setter]
The node's offset along the curve.
- lookahead
double lookahead [@property setter]
How far to look ahead of the curve to calculate the tangent if the node is rotating. E.g. shorter lookaheads will lead to faster rotations. Default value: 4.
- lookahead
double lookahead [@property getter]
How far to look ahead of the curve to calculate the tangent if the node is rotating. E.g. shorter lookaheads will lead to faster rotations. Default value: 4.
- loop
bool loop [@property getter]
bool loop [@property setter]
If true, any offset outside the path's length will wrap around, instead of stopping at the ends. Use it for cyclic paths.
- offset
double offset [@property getter]
double offset [@property setter]
The distance along the path in pixels.
- rotate
bool rotate [@property getter]
bool rotate [@property setter]
If true, this node rotates to follow the path, making its descendants rotate.
- unitOffset
double unitOffset [@property getter]
double unitOffset [@property setter]
The distance along the path as a number in the range 0.0 (for the first vertex) to 1.0 (for the last). This is just another way of expressing the offset within the path, as the offset supplied is multiplied internally by the path's length.
- vOffset
double vOffset [@property getter]
double vOffset [@property setter]
The node's offset perpendicular to the curve.
Point sampler for a Path2D.
This node takes its parent Path2D, 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 descendants of this node. Then, when setting an offset in this node, the descendant nodes will move accordingly.
