lepr	Hi, i'm starting to make a map and i was wondering is there a way for my units to stop when they go on ashenvale stones like if it was cliffs. i tried a little already but i don't find any way to make it works ... Thanks.

Either place pathing blockers, or do something like this:

JASS:

scope Stop
    globals
        group Group
        location Loc
        rect Rectangle=bj_mapInitialPlayableArea
    endglobals    
    
    function C takes nothing returns boolean
        return GetUnitState(GetEnumUnit(), UNIT_STATE_LIFE)<=0 and GetTerrainType(GetLocationX(Loc),GetLocationY(Loc))=='Arck'
    endfunction

    function S takes nothing returns nothing
        set Loc=GetUnitLoc(GetEnumUnit())
      if (C()) then
        call IssueImmediateOrder(GetEnumUnit(),"stop")
      else
      endif
        call RemoveLocation(Loc)
        call DestroyGroup(Group)
    endfunction

    function UG takes nothing returns nothing
        call GetUnitsInRectMatching(Rectangle,null)
        call ForGroup(Group,function S)
    endfunction

   function InitTrig takes nothing returns nothing
        local trigger t=CreateTrigger()
        call TriggerRegisterTimerEventPeriodic(t,0.05)
        call TriggerAddAction(t,function UG)
    endfunction
endscope

Rising_Dusk	I'd recommend pathing blockers. It's much cleaner when units attempt to walk around the terrain impediment than stop because they ran into it.

You could also use the pathmapper external tool to make all tiles of a certain type unpathable. The easiest way to get this tool is with the Jass NewGen pack. To set a tile to unpathable with this tool, just put this line in your map header in the trigger editor: //! external PathMapper Vrck 2 | (this example makes village rocks unpathable, you should replace Vrck with your tile type)

Note that, at least in my experience, tiles set to unpathable this way can not be made pathable again ingame by using destructibles like bridges or invisible platforms.
