How to do it...

We will create the function that computes the quality of the waypoint:

1. Define the function with its parameters:

public static float GetCoverQuality( 
        Vector3 location, 
        int iterations, 
        Vector3 characterSize, 
        float radius, 
        float randomRadius, 
        float deltaAngle) 
{ 
    // next steps 
} 

2. Initialize the variable for handling the degrees of rotation, possible hits received, and valid visibility:

float theta = 0f; 
int hits = 0; 
int valid = 0;

3. Start the main loop for the iterations to be computed on this waypoint and return the computed value:

for (int i = 0; i < iterations; i++) 
{ 
    // next steps 
} 
return (float)(hits / valid); 

4. Create a random position near the waypoint's origin to see whether the waypoint is easily reachable:

Vector3 ...
