Triggering the chain lightning question

[shadowvzs]

if we want make chain lightning ability effect with lightnings then how its look like?
because most of lightning spell what use lightning is instant but chain lightning ability effect look like a projectile with speed, so how its look like? something like create lets say 15 lightning and and last 5 is faded step by step before destroyed and work like multiple missile so each lightning point start after previous with a minimal delay??

i would think they use an algorithm to get slope of the xy coordinates between units and make it piece by piece a certain distance along the slope at .03125 ( most likely time period)

 

[shadowvzs]

unit or lightnings with short length?

Well, you should use timed lightnings.
The lightning itself is instant (from unit to unit), but it has pauses between each target.

Could be done more easily by using 2 separate systems: one to handle the timed lightnings, the other to handle the spell (the pauses between targets, keeping track of how many units have been hit, calling the other system, checking if target unit hasn't been targeted before, that kind of stuff).

Because reals are inaccurate, i recommend this value : 0.031250000

ooo ok thx

what if u want do lightning with arc (horizontal parabola)? because between 2 unit never will be arc / parabola the lightning but also spaming units i guess the worst solution from lagg view

 

[deathismyfriend]

depends on the arc if the arc is along the ground then just using x y points u could create an arc without spamming units. if u want the arc to go up in the air u need to spam dummy flying units to do it.

why parabola? thatd just look silly. if you want an arc, than you just set x,y as the center of the arc than spawn units 10*, 15*, 20*, etc. along the edge to form the arc. its choppy but its the best representation. if you truly want a parabola, than just form the dummys along the graph

The inaccuracy is so small that I don't think those zeroes at the end really matter. It would be interesting to test.

0.03125 is used since it translates to exactly 32 fps per second (1/0.03125 = 32). It is often enough to make things look smooth, but to too often to cause performance issues.
