[LUA] Basic JASS based question on creating units in LUA

Hello,


decided I'd give crack at writing something in LUA and a little trip back to memory lane on WC3 sounded like a nice idea.

I'm struggling however to just replace a unit selected from a unitgroup!

Would appreciate a set of eyes from the JASS guys, let me know if you spot an issue here.

I think it must be with my local target = GetEnumUnit(), with this in mind i started trying to just create a unit but I couldn't get that going either :S

Unit Id's are taken from WorldEditor, tried with default as well 'hgyr' was tested with in case the issue was that 'h000'is a structure, no dice. Tried with quotationg marks instead of inverted commas but no dice there either. Tried Creating a unit without luck, Destructible without luck. Very very confused...

I put some print lines in there to mark and the last item printed is 6, all units are deleted at the end of this and no new units are created which then tells me that in fact GetEnumUnit() is being detected and in fact the issue is with the unit ID? But then why does the flying machine code not work in testing? I am most confused.


Kind regards

Code:
--calls here first

function initSelectTownBuildings()

    --select all units in unit group

    --for each unit in unit group:

  

    print("1")

    local grpobj = GetUnitsOfPlayerAll(Player(0)) --create unit group of place holder objects

    local unitCount = CountUnitsInGroup(grpobj)

    print("2")

    print("unit Count: "..unitCount)

  

    ForGroupBJ(grpobj, initPlaceTownBuildings) --run function for each object in group

end


function initPlaceTownBuildings()

    print("3")

    --if random number == X do action Ax
    --add more stuff later maybe

    local rand = GetRandomInt(1, 1)

    print("4")

    local target = GetEnumUnit() --get the unit pickd

    print("5")

    print("rand: ".. rand)

    --lumbermill scenario

    if (rand == 1) then

        print("6")

        --replace placeholder with lumbermill

        ReplaceUnitBJ(target, 'h000', bj_UNIT_STATE_METHOD_MAXIMUM )

        print("7")
        --CODE DOES NOT REACH THIS POINT!

    end

end

    I want to build a filtration system for my 3d printer, and that shit is so much more complicated than I thought it would be
  • Varine Varine:
    Apparently ABS emits styrene particulates which can be like .2 micrometers, which idk if the VOC detectors I have can even catch that
  • Varine Varine:
    Anyway I need to get some of those sensors and two air pressure sensors installed before an after the filters, which I need to figure out how to calculate the necessary pressure for and I have yet to find anything that tells me how to actually do that, just the cfm ratings
  • Varine Varine:
    And then I have to set up an arduino board to read those sensors, which I also don't know very much about but I have a whole bunch of crash course things for that
  • Varine Varine:
    These sensors are also a lot more than I thought they would be. Like 5 to 10 each, idk why but I assumed they would be like 2 dollars
  • Varine Varine:
    Another issue I'm learning is that a lot of the air quality sensors don't work at very high ambient temperatures. I'm planning on heating this enclosure to like 60C or so, and that's the upper limit of their functionality
  • Varine Varine:
    Although I don't know if I need to actually actively heat it or just let the plate and hotend bring the ambient temp to whatever it will, but even then I need to figure out an exfiltration for hot air. I think I kind of know what to do but it's still fucking confusing
  • The Helper The Helper:
    Maybe you could find some of that information from AC tech - like how they detect freon and such
  • Varine Varine:
    That's mostly what I've been looking at
  • Varine Varine:
    I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
  • Varine Varine:
    I mean I don't use this enough to pose any significant danger I don't think, but I would still rather not be throwing styrene all over the air

    I bitch about Xenforo sometimes but it really is full featured you just have to really know what you are doing to get the most out of it.
  • The Helper The Helper:
    It is just not easy to fix styles and customize but it definitely can be done
  • The Helper The Helper:
    I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
