i'm currently making a Lightning system like in wc3 but with more features.
for example: Create Lightning (Unit Linked)
this will make a lightning between 2 units and flollow them
there will be also like in wc3
CreateLightning and CreateLightningEx (CreateLightningEx will based on the ground zero and the normal one will offset by the ground height)
i also include a Lightning Handler that allows you to handle all your lightnings easily
each lightnig is based on 3 things from the data editor.
1 actor
1 effect
1 model
(so it will be some cnp stuff :/)
if you have questions or things you want inside the system write it down here :)
(NOTE: it's not a library! it's made i the normal trigger editor but i think it doesn't matter)
