This version is pulsing around the position of the caster and doesn't follows him (for sure it doesnt', but it pulses)

Might you reveal to the non-intelligent people (I.E: everyone other then you) whats this spell of awesomeness is supposed to do ?

And by the way, using arrays inside structs isn't recommended.
When using an array inside a struct it cuts off the number of instances of that struct you can have at the same time by this formula: 8192 / array number.
Now I'm not sure if those 36 adds but even if not, its just not recommended. lol.

I don't know if they stack, if not 227 instances are enough, if they stack 38 instances of an ultimate are also enough, since this doesn't even has to be MUI, but I made it because I don't know what will happen to this spell later (at the moment its an ultimate, but I don't know what wil be possible in new gamemodes of my map :) ).

Then, I thought the title tells enough:
It is (or it should be... >.< )a pulsing knockback nova, so a ring (of units) around the caster is pulsing in and out, knocking all units back (in this case just while pulsing out).
I want it to follow the caster, but the second one is neither pulsing nor following, and I just don't get why :(
Oh by the way, I know that my version will NEVER end, I just want to get it working, destroying is easy enough later :)

I found something in the second version:
JASS:
function Frostnova_Movement takes nothing returns nothing
    local FrostnovaData data
    local unit enemy
    local group enemys
    local player owner
    local real x
    local real y
    local integer i = 0
    local integer j = 0
    
    // Data is uninitialized at this point!
    set data.cx = GetUnitX(data.caster) //new
    set data.cy = GetUnitY(data.caster) //new

    //...
