Orbit - Invoker

[Schm0ftie]

Hey guys,

some of you know that I am currently work on a hero, called
Crystal Enchanter, which is basicly a Invoker port. I have
already finished the orb system and started with working at
the abilities that can be created. Currently I want to add
the visual orbs, since they aren't visible around the hero at
the moment. I tried to use a state and refresh it every times
a new orb is set. But my problem is that a state loses his
proxy on refresh. Trying to expire the state before re applying
it seems not to work too (idea was to put the delete orbits
thing in <onexpired>. Maybe you guys have ideas how to
make it. The main problem is that I need to delete old orbits
and spawn new one, every time the player changes the orbs.

I hope someone has a good idea, else I would leave the visual
as it is know, only visible on the ability buttons and do the rest
of the abilities.

For those who want to look into the state, there is the code.

Ok, so as I said my idea is based on states. Obviously we must create 3 states for orbs (let's call them State1,State2,State3).
There is maximum of 3 states same time, and we'll give them order by creating singly linked list.

So, let's focus on abilities. All that it must do is to add new state to list and remove 1st element

Some code (not full :P)

ablilities and states 2 and 3 are similar:)



Let's think about Invoke skill
