Random walker through points

[Chrisir]

The 3D idea will not work with your plans to stop a walker when crossing another line though

Better stay 2D…

Vector math for line-to-line intersection

While learning about vectors, I worked through this to better understand line-to-line intersection math instead of simply using it “because it works”. final int N = 4; // Fixed number to make two segments int MAX_DIST = 20; // Control points PVector[] p = new PVector[N]; boolean held = false; int nearest = -1; float startx = 0; float starty = 0; float DIV_TOO_FAR = 0.00001; // Calculates the intersection with vectors. // Surely this uses the same math as solving the equations. // Input: // …
