Transport assist widget

[DZHIBRISH]

Hi.Why isnt the transport assist widget working?the one that allows u to set a transport to guard labs and it stops units built and makes the transport cary them to the labs rally point.
Whoever did the widget...its awsome can you fix it please?

[Tim-the-maniac]

I made it tho I cant find the DL link for it anymore (there is still some part of UF serving spring files right?). Also I dont have spring to test it but im sure plenty of people here can fix and make it less crappy at the same time.

[DZHIBRISH]

You heard the man.YOU exist...so go make it good..

If someone can post the gadget I'm happy to have a gander and see what's wrong. I like the concept behind the widget and would love to have it working, so seems reasonable that I should look at it and hopefully get it working.

Can someone post it please? Or give the name of it so I can do a google/uf search for it please?

Here's one I found but I don't know if it's up-to-date:

Code: Select all

--[[
When this widget is enabled, air transports guarding factories will 
automatically take new units built at the factory to the destination of the factory
--]]

function widget:GetInfo()
  return {
    name      = "Transportation Assister",
    desc      = "Transports guarding factories will automatically move new units",
    author    = "Ray",
    date      = "Feb 18, 2007",
    license   = "GNU GPL, v2 or later",
    layer     = 0,
    enabled   = false
  }
end

urh please delete that :p. Best to just remake it and also add something which checks the unload command locations to make sure 2 arent placed too near each other to cancel out.

[Licho]

I modified this widget and it works for me (uses area unload and stops unit it tries to pick-up)

http://widgets.licho.eu/unit_transport_assist.lua

[DZHIBRISH]

licho..awsome..jsut one thing.. maybe make it enabled by default..

[DZHIBRISH]

another thingy can you correct it so that a transport wont move if its not completly full..cause otherwise the transports are wasted .the t2 transport for example.plus the t1 transports in my mod can carry more than 1 unit as well.

[[XIII]Roxas]

Enabling it by default is a simple changing of enabled=false to true in the LUA.

[DZHIBRISH]

ya ik now. i did that..but people who have even less idea about lua than me..

[REVENGE]

Why did I not get this memo.

[DZHIBRISH]

by the way sometimes it doesnt command thae transports to area unload
which bcomes ver unconvinient.
