[Open-source] Simple Unity3d Vision system

Vision is simple system to realize a spherical AI vision in your projects. This is how it works:

• Create single gameObject with VisibleGrid in the scene for the system to work. (It serves as a cache).
• Put Visible component on the gameObjects that you want to be visible.
• Use IVisibleListener interface on other components of this object to know when you're being seen.
• Put Vision component on the gameObjects taht you want to see.
• Use IVisionListener interface on other components of this object to know what you see.
• Or just use VisiblesInSight().

I've used the current version for simple RTS RPG mechanics, works perfectly with big amount of objects. I've come to conclusiton that manual sphere-checking is more comfortable than using trigger colliders: you often already have a rigidbody collider on you gameObject, so you have to create another sub-object with a delegate, etc, etc. Plus, this version is easily convertible to situations where Unity physics couldn't be used (deterministic RTS engine, for example).

Future plans:

• Optimizaitons where neccessary.
• Cone-shaped vision along the forward vector of object's transform.
• Raycasting.
