How would you create a spline that does the following?
After I saw this topic: http://discourse.urho3d.io/t/splines-in-urho/2928/1 I wanted to try and create a spline which describes a foot setting down and lifting off of the ground. Basically, something that looks like this:
I determined these key times by looking at a walk animation in the editor. I figure I could spline between Vector2's, so I created the spline like this:
sp.AddKnot(Variant(Vector2(0.29, 0.0))); // foot down
sp.AddKnot(Variant(Vector2(0.39, 1.0))); // foot on ground
sp.AddKnot(Variant(Vector2(0.81, 1.0))); // foot still on ground
sp.AddKnot(Variant(Vector2(0.91, 0.0))); // foot lift
Then I use this code to calculate the weight:
float norm = animState_.time / animState_.length;
float weight = sp.GetPoint(norm).GetVector2().y;
When I look at the
weight value I'm getting something that looks like a sine wave and not the expected figure. What am I doing wrong?
