1. how to move dummy every second in jass

I decided to reply with an example, in this case dummy moves every 0.03 seconds so it seems a continuous slide, and flies from ability caster in direction cast for fixed time. You will ahve to customize this to what ur going for since your question doesn't specify where you want him to move or for how long.

function myabilitycast ...
set tp1=GetUnitLoc(GetTriggerUnit())
set mydummy=CreateUnit...dummy
set tp2=GetSpellLoc()
set arangle=AngleBetweenPoints(tp1,tp1)
call RemoveLocation (tp1)
call RemoveLocation (tp2)
call EnableTrigger(udg_trigger196)
call TriggerSleepAction(.5)
call DisableTrigger(udg_trigger196)
endfunction
...
function Trig_per_move takes nothing returns nothing
    if mycondition2() then  
    do effect
    else
        set tp1=GetUnitLoc(mydummy)
        set tp2=PolarProjectionBJ(tp1,12.00,arangle)
        call SetUnitPositionLocFacingLocBJ(mydummy,tp3,tp2)
        call RemoveLocation (tp1)
        call RemoveLocation (tp2)
endfunction
...
    set udg_trigger196=CreateTrigger()
    call DisableTrigger(udg_trigger196)
    call TriggerRegisterTimerEventPeriodic(udg_trigger196,0.03)
    call TriggerAddAction(udg_trigger196,function Trig_per_move)
