Moving a zone

[The Cartooners]

Here is the original location as created within the builder

 

zoneBronzeAgeMan.Points = {

ZonePoint(51.3176,-2.9823,0),

ZonePoint(51.3176,-2.982,0),

ZonePoint(51.3174,-2.982,0),

ZonePoint(51.3174,-2.9823,0)

}

zoneBronzeAgeMan.OriginalPoint = ZonePoint(51.3175,-2.98215,0)

 

And here is where I want to move the zone (under a certain condition)

 

zoneBronzeAgeMan.Points = {

ZonePoint(51.3166,-2.9820,0),

ZonePoint(51.3166,-2.9817,0),

ZonePoint(51.3162,-2.9817,0),

ZonePoint(51.3162,-2.9820,0)

}

 

zoneBronzeAgeMan.OriginalPoint = ZonePoint(51.3164,-2.98185,0)

 

as placed within a function within the Author Script section. As you can see the zone will not move far. Its purpose is that when the Player returns to a character (within the zone) that the character has moved a little.

 

When this code is executed I receive an error

 

First arguement must be a zonepoint

 

What have I missed?

Here's what I did for the "CenterZoneOnPoint" method in Whack-A-Lackey. It takes in a zone and a ZonePoint, the center of where I want the zone:

 

--Moves the zone to a ZonePoint.  This is used to prime all zones
function CenterZoneOnPoint(zZone, point)
 local dist = Wherigo.Distance(0, 'ft')
 local newZp = Wherigo.TranslatePoint(point, dist, 0)   -- new center point for the new zone	
 dist = Wherigo.Distance(ZoneRadius, 'ft')
 local pts = {
Wherigo.TranslatePoint(newZp, dist, 45),
Wherigo.TranslatePoint(newZp, dist, 135),
Wherigo.TranslatePoint(newZp, dist, 225),
Wherigo.TranslatePoint(newZp, dist, 315),
 }

 zZone.Active = false
 zZone.OriginalPoint.latitude = newZp.latitude
 zZone.OriginalPoint.longitude = newZp.longitude

 zZone.Points = pts
end 

 

If you still need help, I can post some other things and experiment a little. For now, I have to get back to work.

 

Edit: I forgot to mention you do have to set the zone as inactive to move it.

Thanks Ranger,

 

Here's how I got it to work

 

1. Copied your function

2. Added the following to my event

 

local zp = Wherigo.ZonePoint(51.31710, -2.982,0) -- New Location of existing zone

CenterZoneOnPoint(zoneBronzeAgeMan, zp)

 

3. The only change that I made within your function was the need to add

 

local ZoneRadius = 60

 

Voila

 

I failed to find anything within the LUA reference manual regaring ZonePoints etc. So once again thanks.

Hello Ranger Fox and others.

 

I want to use this function (I am building a cartridge that is to be published during an Event - so to spread out the players, I want to give them alternative routes.) I use a text-editor to insert the function under "-- #Author Functions Go Here# --". Then in the same editor I add code to call the function under one of the builder-generated events. It seems to work OK, but in the builder I get a "LUA Parsing Error", and in the source it says "Builder Generated functions, Do not Edit, this will be overwritten". Can I just ignore these warnings, or is there another way to call a user defined function?

 

Please keep your answer in a simple language (preferentially with an simple example) as I am literally a BASIC programmer.

I'm not quite sure what the last part means here. That comment about "Builder Generated functions" is in every cartridge. Can you upload your Lua file (or the relevant parts, if the rest is secret) here so we can look at it?

In Earwigo (alternative builder), you can insert an arbitrary Lua statement at any point, without causing any sort of parsing issues, because the Earwigo editor doesn't look at the statement. Also, the "Author Functions" section has some Lua syntax checking. And, although it exists in 5 or 6 languages already, we need someone to translate into Danish... so if you want to try it out, please mail me via my profile.

The Function:

-- #Author Functions Go Here# --

function CenterZoneOnPoint(zZone, point)

local ZoneRadius = 60

local dist = Wherigo.Distance(0, 'ft')

local newZp = Wherigo.TranslatePoint(point, dist, 0) -- new center point for the new zone

dist = Wherigo.Distance(ZoneRadius, 'ft')

local pts = {

Wherigo.TranslatePoint(newZp, dist, 45),

Wherigo.TranslatePoint(newZp, dist, 135),

Wherigo.TranslatePoint(newZp, dist, 225),

Wherigo.TranslatePoint(newZp, dist, 315),

}

 

zZone.Active = false

zZone.OriginalPoint.latitude = newZp.latitude

zZone.OriginalPoint.longitude = newZp.longitude

 

zZone.Points = pts

end

-- #End Author Functions# --

 

The call:

function zoneStartzone:OnEnter()

-- #GroupDescription=Script --

-- #Comment=Script Comment --

local zp = Wherigo.ZonePoint(56.034841, 9.991811,0)

CenterZoneOnPoint(zoneQ100, zp)

ztimertimer1:Start()

end

------End Builder Generated functions, Do not Edit, this will be overwritten------

I will do that.

Double Click the error:

Yes, you've hit an issue with the Groundspeak builder: you can protect your own function definitions by putting them in the Author Functions section, but as far as I know, you can only protect the calls to those functions by commenting them out before you reopen the Lua file in the builder. It would be nice if the builder could at least skip a line containing just

Lua-identifier(something,something,something)

 

I have made you an Earwigo account. You can upload your existing Lua file into it. The upload function claims to be able to accept anything which the Groundspeak builder can output. Without examining the code closely, I can't say whether it will also accept your call of the author function. If it doesn't, the line will be omitted, and you will need to put it back as a "Lua statement". But after that, you shouldn't have to jump through hoops too much... well, apart from the bugs.
