Hi! I’m trying to follow How to make dynamic waves with water which was made in godot 3.3. I’ve been able to follow most of the tutorial, but I run in to trouble when trying to import the smoothpath script below. I’ve added @ to the export variables, but then I’m stuck.
Could I get any help with converting this script to get it to work in godot 4?
class_name SmoothPath
extends Path2D
export var spline_length = 8
export(bool) var _smooth setget smooth
export(bool) var _straighten setget straighten
export(Color) var color = Color(1,1,1,1)
var width = 8
func straighten(value):
if not value: return
for i in range(curve.get_point_count()):
curve.set_point_in(i, Vector2())
curve.set_point_out(i, Vector2())
func smooth(value):
if not value: return
var point_count = curve.get_point_count()
for i in point_count:
if i >0 and i < point_count-1:
var spline = _get_spline(i)
curve.set_point_in(i, -spline)
curve.set_point_out(i, spline)
func _get_spline(i):
var last_point = _get_point(i - 1)
var next_point = _get_point(i + 1)
var spline = last_point.direction_to(next_point) * spline_length
return spline
func _get_point(i):
var point_count = curve.get_point_count()
i = wrapi(i, 0, point_count )
if i >1 and i < point_count-1:
return curve.get_point_position(i)
elif i <= 1:
return Vector2(curve.get_point_position(1).x - spline_length,curve.get_point_position(1).y)
elif i >= point_count-1:
return Vector2(curve.get_point_position(point_count-1).x + spline_length,curve.get_point_position(point_count-1).y)
func _draw():
var points = curve.get_baked_points()
if points:
draw_polyline(points, color, width, true)
