Not exactly what I'm looking for but I've opt it for another less "elegant" way of doing it.
I set up a table of points and their values.
The object looks like
public class CustomCurve {
public float[] points;
public float[] height;
public int size;
public CustomCurve(int size){
points = new float[size];
height = new float[size];
this.size = size;
}
}
points are the points on line t;
height are their values from which the lines are drawn from one point to another.
The function that goes with it:
public static float Custom(float t, CustomCurve c)
{
float result = 0.0f;
if(t > 1) return c.height[c.height.Length-1];
if(t < 0) return c.height[0];
for (int i = 0; i < c.size-1; i++) {
if(t >= c.points[i] && t <= c.points[i+1]){
result = Linear(t/(c.points[i+1]-c.points[i]),c.height[i],c.height[i+1]);
break;
}
}
return result;
}
Simply put, I iterate over the points on my t line. Check if t is between any of the points and calculate the inner interpolation of two points. Using the simple linear interpolation equation:
v0+(v1-v0)*t;
So a table of:
Point Height
0 0
0,2 0,95
0,3 1
0,33 0,95
0,4 0
0,5 0,95
0,7 1
0,8 0,95
1 0
Looks like:
Granted, the line won't be smooth. But if I need more detail I add more points. And once created I can reuse them.
If anyone knows a way to get rid of the forloop please do tell!
