Hi,

i'm trying to make this Hoof Stomp spell vJASS MUI but it's not working.

i've already made a GUI working version but converting it is tricky.

i've uploaded the test map which contains both GUI and my vJASS versions so you can test them and see how the spell is meant to work etc.

If it helps, i can post the GUI version here too.

below is the vJASS code for the spell:

JASS:

        private constant real INTERVAL = 0.03    //cicles of the timer
        private constant string STOMP_EFFECT = "Abilities\\Spells\\Orc\\EarthQuake\\EarthQuakeTarget.mdl"

vJass and MUI should never be used in the same sentence :p
When you use vJass MU-Instancability is assumed :p

Suggestions:
-Hold control and click on those red evil BJs so you can remove them.
-Put the spell in a library
-Put the initialization in a static method (onInit) inside a module and implement that module into a struct:
JASS:
private module Init
    private static method onInit takes nothing returns nothing
        // your init here
    endmethod
endmodule
private struct Inits extends array
    implement Init
endstruct

GetSpellTargetX and Y has problems coz the spell is 'no target', not target point...

Anyway, I've made a spell similar to this before, but no damage...

2 calls of GetTriggerUnit() will have better efficiency than
declaring a local, setting it to the triggering unit, referencing
it twice, then nulling it.

Importantly, it's less text as well so it keeps the map size
down.

I dont know... :S
Has that been tested yet?
Actually, come to think of it, at the C++ level, GetTriggerUnit probably just returns an instance of class unit through an array read :p
The array index being trigger dependent.

When we want to repeat a function call thrice, that's where I draw the line and include a local :p
