/*For mage 'Bolt' line and other various spells.
-This is mostly accurate for how the modern clients handle this effect.
-It was changed at some point to use an actual projectile as done here (opposed to a particle effect in classic)
-The projectile graphic appears to be that of 'Ball of Sunlight' ID 80648 and will be visible to anyone in SoF+
-There is no LOS check to prevent a bolt from being cast. If you don't have LOS your bolt simply goes into whatever barrier
and you lose your mana. If there is LOS the bolt will lock onto your target and the damage is applied when it hits the target.
-If your target moves the bolt moves with it in any direction or angle (consistent with other projectiles).
-The way this is written once a bolt is cast a timer checks the distance from the initial cast to the target repeatedly
and calculates at what predicted time the bolt should hit that target in client_process (therefore accounting for any target movement).
-The way this is written once a bolt is cast a the distance from the initial cast to the target repeatedly
check and if target is moving recalculates at what predicted time the bolt should hit that target in client_process
When bolt hits its predicted point the damage is then done to target.
Note: Projectile speed of 1 takes 3 seconds to go 100 distance units. Calculations are based on this constant.
Live Bolt speed: Projectile speed of X takes 5 seconds to go 300 distance units.
