Types ¶
type Advanced ¶
type Advanced = class
Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.
type Expanded ¶
func (Expanded) AddPoint ¶
func (self Expanded) AddPoint(position Vector2.XY, left_tangent Float.X, right_tangent Float.X, left_mode TangentMode, right_mode TangentMode) int
Adds a point to the curve. For each side, if the [code]*_mode[/code] is [constant TANGENT_LINEAR], the [code]*_tangent[/code] angle (in degrees) uses the slope of the curve halfway to the adjacent point. Allows custom assignments to the [code]*_tangent[/code] angle if [code]*_mode[/code] is set to [constant TANGENT_FREE].
type Extension ¶
Extension can be embedded in a new struct to create an extension of this class. T should be the type that is embedding this Extension
func (*Extension[T]) AsRefCounted ¶
func (self *Extension[T]) AsRefCounted() [1]gd.RefCounted
func (*Extension[T]) AsResource ¶
type ID ¶
ID is a typed object ID (reference) to an instance of this class, use it to store references to objects with unknown lifetimes, as an ID will not panic on use if the underlying object has been destroyed.
type Instance ¶
This resource describes a mathematical curve by defining a set of points and tangents at each point. By default, it ranges between [code]0[/code] and [code]1[/code] on the X and Y axes, but these ranges can be changed. Please note that many resources and nodes assume they are given [i]unit curves[/i]. A unit curve is a curve whose domain (the X axis) is between [code]0[/code] and [code]1[/code]. Some examples of unit curve usage are [member CPUParticles2D.angle_curve] and [member Line2D.width_curve].
var Nil Instance
Nil is a nil/null instance of the class. Equivalent to the zero value.
func (Instance) AddPoint ¶
Adds a point to the curve. For each side, if the [code]*_mode[/code] is [constant TANGENT_LINEAR], the [code]*_tangent[/code] angle (in degrees) uses the slope of the curve halfway to the adjacent point. Allows custom assignments to the [code]*_tangent[/code] angle if [code]*_mode[/code] is set to [constant TANGENT_FREE].
func (Instance) AsRefCounted ¶
func (self Instance) AsRefCounted() [1]gd.RefCounted
func (Instance) AsResource ¶
func (Instance) Bake ¶
func (self Instance) Bake()
Recomputes the baked cache of points for the curve.
func (Instance) BakeResolution ¶
func (Instance) CleanDupes ¶
func (self Instance) CleanDupes()
Removes duplicate points, i.e. points that are less than 0.00001 units (engine epsilon value) away from their neighbor on the curve.
func (Instance) GetDomainRange ¶
Returns the difference between [member min_domain] and [member max_domain].
func (Instance) GetPointLeftMode ¶
func (self Instance) GetPointLeftMode(index int) TangentMode
Returns the left [enum TangentMode] for the point at [param index].
func (Instance) GetPointLeftTangent ¶
Returns the left tangent angle (in degrees) for the point at [param index].
func (Instance) GetPointPosition ¶
Returns the curve coordinates for the point at [param index].
func (Instance) GetPointRightMode ¶
func (self Instance) GetPointRightMode(index int) TangentMode
Returns the right [enum TangentMode] for the point at [param index].
func (Instance) GetPointRightTangent ¶
Returns the right tangent angle (in degrees) for the point at [param index].
func (Instance) GetValueRange ¶
Returns the difference between [member min_value] and [member max_value].
func (Instance) OnDomainChanged ¶
func (Instance) OnRangeChanged ¶
func (Instance) PointCount ¶
func (Instance) RemovePoint ¶
Removes the point at [param index] from the curve.
func (Instance) Sample ¶
Returns the Y value for the point that would exist at the X position [param offset] along the curve.
func (Instance) SampleBaked ¶
Returns the Y value for the point that would exist at the X position [param offset] along the curve using the baked cache. Bakes the curve's points if not already baked.
func (Instance) SetBakeResolution ¶
func (Instance) SetMaxDomain ¶
func (Instance) SetMaxValue ¶
func (Instance) SetMinDomain ¶
func (Instance) SetMinValue ¶
func (Instance) SetPointCount ¶
func (Instance) SetPointLeftMode ¶
func (self Instance) SetPointLeftMode(index int, mode TangentMode)
Sets the left [enum TangentMode] for the point at [param index] to [param mode].
func (Instance) SetPointLeftTangent ¶
Sets the left tangent angle for the point at [param index] to [param tangent].
func (Instance) SetPointOffset ¶
Sets the offset from [code]0.5[/code].
func (Instance) SetPointRightMode ¶
func (self Instance) SetPointRightMode(index int, mode TangentMode)
Sets the right [enum TangentMode] for the point at [param index] to [param mode].
func (Instance) SetPointRightTangent ¶
Sets the right tangent angle for the point at [param index] to [param tangent].
func (Instance) SetPointValue ¶
Assigns the vertical position [param y] to the point at [param index].
type TangentMode ¶
type TangentMode int //gd:Curve.TangentMode
const ( /*The tangent on this side of the point is user-defined.*/ TangentFree TangentMode = 0 /*The curve calculates the tangent on this side of the point as the slope halfway towards the adjacent point.*/ TangentLinear TangentMode = 1 /*The total number of available tangent modes.*/ TangentModeCount TangentMode = 2 )
