steering

2D vector based steering behaviors. Based on Craig Reynolds' Steering Behaviors For Autonomous Characters.

#Install

``shell
npm install steering
`
#Usage
Steering uses the vectors library as a dependency. This means that it expects two element javascript arrays
passed in as arguments.

##Seek

`javascript
var seek = require('steering').seek;
var force = seek(target, position, current_velocity, max_velocity, slowing_radius);
`

##Flee
`javascript
var flee = require('steering').flee;
var force = flee(target, position, current_velocity, max_velocity);
`

##Wander
`javascript
var flee = require('steering').wander;
var force = wander(current_velocity, wander_distance, wander_radius, wander_angle, angle_change);
`
##Evade
`javascript
var flee = require('steering').evade;
var force = evade(target, position, max_velocity, current_velocity, target_velocity);
`

##Pursuit
`javascript
var flee = require('steering').pursuit;
var force = pursuit(target, position, max_velocity, current_velocity, target_velocity);
`

##Avoidance
`javascript
var flee = require('steering').avoidance;
var force = avoidance(target, position, current_velocity, max_avoid_ahead, max_velocity, avoidance_force);
