lightning

working on sub strikes but not active atm
changed some mats
Mana and Health

added first pass health and mana bars
Added intial costs for spells
and growth or length costs for spells.
Spells will auto fire or fail when out of mana
Need to add some feed back with attacks and mana costs
Fire damage part 1

Add basic fire spawning from fireball
Has max spawn num per ball and max spawn rate
need to add some collision when spawning
Fire damage part 2

Fire damage now scales on mass
fireball now goes threw enemies
Fire only spawns when fireball does not touch other fire.
Can still cause loss of fps if too many fireballs
firebals now die after time (based on mass)
Lightning Damage Now works

Collider at end of strike
Does High damage on hit
Lightning attack ends

add shrink state to lightning attack
will shrink to nothing and then destroy self
time alive is based on the size.
might to be too short initaly
