Lock units into locations

[khamarr3524]

Hello, I'm certain that I posted this before, but I'm not going to necro that post and this post will address the problem more potently and specifically, please tell me if this is possible, or should just be done by modifying the terrain (last resort).

I am working on a map that is split into various islands and there are areas of the map that I don't want units to be able to go to I.E the waterfall area, the ocean, cliffs etc. However, using some spells that have .03 timers and move the unit in a parabolic motion (arching), they can go into the areas I wish them to not enter. I used Bribe's UnitIsMoving library to create a system that keeps them out, HOWEVER, their z (vertical) height is bugged and they walk above the ground, any idea on how I can fix this problem?

Can't you just use pathing blockers ? (It's in the doodads palette).

And in the trigger when you move the units, before moving them, check with an if (pathing is off at temppoint2) then Remove unit from the movingGroup.

Pathing blockers don't work on them because as the trigger loops through time, it eventually bypasses the pathing blocker coordinates. I'll post my system here.

library UnitBadArea initializer init
    struct UnitBadArea
        private static method checkUnit takes unit u returns nothing
            local real x = GetUnitX(u)
            local real y = GetUnitY(u)
            local real retX = UnitMoving(GetUnitUserData(u)).x
            local real retY = UnitMoving(GetUnitUserData(u)).y
            if GetTerrainType(x, y) == 'Avin' or GetTerrainType(x,y) == 'Arck' then
                call SetUnitX(u, retX)
                call SetUnitY(u, retY)
            endif
            set u = null
        endmethod
        private static method getUnits takes nothing returns nothing
            local unit u
            local group g = CreateGroup()
            call GroupEnumUnitsInRect(g, bj_mapInitialPlayableArea, null)
            loop
                set u = FirstOfGroup(g)
                exitwhen u == null
                call GroupRemoveUnit(g, u)
                call .checkUnit(u)
            endloop
            call DestroyGroup(g)
            set g = null
        endmethod
        static method main takes nothing returns nothing
            call .getUnits()
        endmethod
    endstruct
    
    private function init takes nothing returns nothing
        call TimerStart(CreateTimer(), .03, true, function UnitBadArea.main)
    endfunction
endlibrary

SetUnitX/Y always bug even if the path is blocked or outside map bounds, so you need to check if the path in front of your caster (say offset of 60) is walkable or blocked...or you may use the native SetUnitPosition...

Will SetUnitPosition fix the issue with the z flight height? The spells are in GUI (I didn't make them).

 

[mckill2009]

why dont you try it or use the TerrainPathability Library?...

 

[khamarr3524]

None of these work, the z offset is still bad. I don't know if this is just the spell and how I could fix this.
