Dynamic Boundary Calculations

[Xevion]

The Boid code should be revised to allow for dynamic specification of 'Boundaries'.
Boundaries are spaces where Boids should avoid or inversely, drawn into. Additionally, the code should support more than one boundary - with different options like the forces that are applied to Boids, the range, the bias, the type (draw in/out) and anything else needed.

This could create some very amusing and fun behaviour:

• Boundaries around UI elements pushing Boids
• Custom boundaries for the user

I forgot to mention, but this behavior could work with LeanTween if the calculations are not difficult to implement. For example, when an tween is in progress, a callback updating the boundary based on the current position of the text would be a good idea, but this may be difficult to implement if LeanTween does not allow users to slip in a callback.

If LeanTween does not allow this functionality, the only other way would be checks implemented on Update(), but this may drag down performance long term if I'm not careful.

Another Boundary related feature would be spherical boundaries - these would be pretty easy to implement, seeing how a simple distance/radius check would suffice.
