[Snippet] FlyHeight

The documentation has a brief explanation as to why I made this.

Code

JASS:
/*************************************
*
*   FlyHeight
*   v2.0.0.0
*   By Magtheridon96
*
*   - Warcraft III movement types are pretty
*     bugged. It would be much better to write
*     them from scratch. This system allows
*     you to create flying units with changeable
*     heights.
*
*     All units must have Movement Type Foot.
*
*   Requires:
*   ---------
*
*       - UnitIndexer by Nestharus
*           - hiveworkshop.com/forums/jass-resources-412/system-unit-indexer-172090/
*       - Table by Bribe
*           - hiveworkshop.com/forums/jass-resources-412/snippet-new-table-188084/
*       - AutoFly by Nestharus
*           - hiveworkshop.com/forums/jass-resources-412/snippet-autofly-unitindexer-version-195563/
*
*   API:
*   ----
*
*       - struct FlyHeight extends array
*
*           - static method operator [] takes unit u returns thistype
*               - Returns an instance of the struct given a unit
*
*           - static method setDefault takes integer unitType, real flyHeight returns nothing
*               - When a unit of a certain type enters the map, his height will be set
*                 to a default value input by the user using this function.
*
*           - method operator height takes nothing returns real
*               - Returns the height of a unit
*
*           - method operator height= takes real newHeight returns nothing
*               - Sets the height of a unit
*

library FlyHeight requires UnitIndexer, Table, AutoFly

    private module Init
        private static method onInit takes nothing returns nothing
            set default = Table.create()
        endmethod

            local integer unitType = GetUnitTypeId(this.unit)
            
            if haveDefault(unitType) then
                set height_p[this] = default.real[unitType]
                call SetUnitFlyHeight(this.unit, height_p[this], 0)

                set height_p[this] = newHeight
                call SetUnitFlyHeight(this.unit, newHeight, 0)
            endif
        endmethod

        implement Init
    endstruct
    
endlibrary

Demo

JASS:
struct Demo extends array
    private static method onInit takes nothing returns nothing
        local unit peasant
        local unit hawk
            
        call FlyHeight.setDefault('hpea', 200)
        call FlyHeight.setDefault('hdhw', 150)
            
        set peasant = CreateUnit(Player(0), 'hpea', -256, 0, 270)
        set hawk = CreateUnit(Player(0), 'hdhw', 256, 0, 270)
            
        call DisplayTimedTextToPlayer(GetLocalPlayer(), 0, 0, 60, R2SW(FlyHeight[peasant].height, 5, 1))
        call DisplayTimedTextToPlayer(GetLocalPlayer(), 0, 0, 60, R2SW(FlyHeight[hawk].height, 5, 1))
            
        call TriggerSleepAction(5)
            
        set FlyHeight[peasant].height = 900
        set FlyHeight[hawk].height = 2
            
        call DisplayTimedTextToPlayer(GetLocalPlayer(), 0, 0, 60, R2SW(FlyHeight[peasant].height, 5, 1))
        call DisplayTimedTextToPlayer(GetLocalPlayer(), 0, 0, 60, R2SW(FlyHeight[hawk].height, 5, 1))
            
        set peasant = null
        set hawk = null
    endmethod
endstruct

And I posted a test-map.
