Lightning Z Location

[Nightmare Moon]

Hello. I need a trigger that can create lightning from Z location to point i want. I know it's not hard but i don't know. +rep to helper as always.

Instead of GetLocationX, you can use GetUnitX. But you might need to use locations for the last parameters, z1 and z2.

Thank you Maker. jk2pach sorry but i don't know nothing about JASS so it's not for me.
Edit: x1, x2, y1, y2 are those coordinates for the ground point?? And z1, z2 for Z point? So should i use variables for them.

 

[Maker]

Yes, x1 , x2 , y1 , y2 are coordinates.

Point(x1 , y1) = The starting point
Point(x2, y2) = The ending point
z1 = Lightning height offset at the starting point
z2 = Lightning height offset at the starting point

You can do it like this:

Set Location1 = Position of Unit(u)
Set z1 = GetLocationZ(udg_Location1)

Now the starting point will be at grond level. If you do this:
Set z1 = GetLocationZ(udg_Location1) + 100
The starting point will be slightly above ground.
