GetAllOfType in WhereYouGo

[+HackAMen]

Hi,

 

I have been trying to use the method GetAllOfType of a cart to list all the zones, ala objMyCart:GetAllOfType('Zone')

 

I see that this works in the emulator but when I try to use it in WhereYouGo built with Urwigo I get an exception, namely Tried to call nil.

 

I've seen that there were issues, namely

https://code.google.com/p/openwig/issues/detail?id=160

but as that was some time ago I'd hoped that it was fixed.

 

Not only that, but I've tried this rather basic call which is working in the emulator but not WhereYouGo

 

local dist, angle = Wherigo.VectorToZone( Player.ObjectLocation, objTest1 )

 

objTest1 is a zone created in Urwigo

 

It also fails with 'Tried to call nil'

 

Am I missing something?

 

Thanks.

There isn't such a function in OpenWIG. You have to write it by your own. It isn't very difficult.

 

function GetAllOfType(type)
 result = {}
 for k,v in ipairs(cart.AllZObjects) do
   if Wherigo.NoCaseEquals(tostring(v), "a "..type.." instance") then
     table.insert(result, v)
   end
 end
 return result
end

Call it for example by

 

for k,v in ipairs(GetAllOfType("Zone")) do
 print(v.Name)
end

to get all Zones or

 

for k,v in ipairs(GetAllOfType("ZItem")) do
 print(v.Name)
end

to get all ZItem objects.

Thank you so much, that's spot on.

 

I have to ask for some more help though. Using your code I have created this

 

for k,v in ipairs(objTestCartridge.AllZObjects) do
	if Wherigo.NoCaseEquals(tostring(v), "a Zone instance") then
		if  Wherigo.NoCaseEquals( tostring(v.Name), "Test1" ) then
			dist, angle = Wherigo.VectorToZone( Player.ObjectLocation, v )
			break
		end
	end
end

 

I am getting a 'Tried to call nil' exception on Wherigo.VectorToZone again in WhereYouGo and not the emulator. Would you say that VectorToZone is not implemented in Wherigo or that ObjectLocation is not, or something else?

 

I should say Player = Wherigo.Player

 

/edit

OK looking at https://code.google.com/r/biylda-openwig/source/browse/OpenWIGLibrary/src/cz/matejcik/openwig/WherigoLib.java

It looks like VetorToPoint is implemented but not VectorToZone. Does that seem correct to you?

 

/edit 2

After reading this http://forums.Groundspeak.com/GC/index.php?showtopic=316825

I can confirm that VectorToPoint works in WhereYouGo and it does exactly what I need.

 

Thanks for pointing me in the right direction!
