Save objects to .map file

[Zorgman]

How can I save script generated objects to a .map file?

[Patrick]

Loop trough all objects, get details and write it to a file, like any .map editor file.
You can check the syntax in an existing .map file.

 

Something like that

-- CLIENT SIDE

local objects = getElementsByType("object")
local file    = fileCreate("clonedmap.map")

fileWrite(file, "<map>\n")
for i = 1, #objects do
    local obj        = objects[i]
    local x, y, z    = getElementPosition(obj)
    local rx, ry, rz = getElementRotation(obj)

    row = ('\t<object id="something (%d)" breakable="%s" interior="%d" collisions="%s" alpha="%d" model="%d" doublesided="%s" scale="%d" posX="%f" posY="%f" posZ="%f" rotX="%f" rotY="%f" rotZ="%f"></object>\n'):format(
        i,
        tostring(isObjectBreakable(obj)),
        getElementInterior(obj),
        tostring(getElementCollisionsEnabled(obj)),
        getElementAlpha(obj),
        getElementModel(obj),
        tostring(isElementDoubleSided(obj)),
        getObjectScale(obj),
        x, y, z,
        rx, ry, rz
    )
    fileWrite(file, row)
end
fileWrite(file, "</map>")

fileClose(file)

An alternative is to save an specific part of the element tree. Pick the method that works best for you.

 

local file = xmlCreateFile ("map.xml", "map")
local baseElement = createElement("temporary")

--[[
	
]]

local element = -- createObject, createVehicle, etc. etc,

setElementParent(element, baseElement)

--[[
	
]]

saveMapData ( file, baseElement )
xmlSaveFile ( file )
xmlUnloadFile ( file )

destroyElement(baseElement) -- destroy every element, parent as well as the children thanks to propagation

Pro's

• Flexibility, you do not have to write specific code for other elements.

 

Cons:

• Serverside only
• No custom properties with special characters, for example : notations and code comments on the fly.
• All properties are copied, you do not have fully control which ones are saved.

saveMapData...  thats new for me 

[Zorgman]

I didn't knew about saveMapData either, this was actually what I was looking for so I tried it first, but it produced an xml file with empty object elements, not sure what i messed up Patrick's solution worked for me, I got my map. Thank you both!

You didn't mess anything up, but it seems the function has been broken somewhere on the versioooon-way.

The wiki example didn't work either.

local baseElement = createElement("map-dinner")

--[[
	
]]

local element = createObject ( 1337, 5540.6654, 1020.55122, 1240.545, 90, 0, 0 )
setElementParent(element, baseElement)

--[[
	
]]


local file = xmlCreateFile ("map.xml", "map")
saveMapData ( file, baseElement, true )
xmlSaveFile ( file )
xmlUnloadFile ( file )

--[[
<map>
    <object></object>
</map>
]]

local file = xmlCreateFile("saved.map", "map")
if file then
   saveMapData ( file, getResourceRootElement(getThisResource()), true )
   xmlSaveFile ( file )
   xmlUnloadFile ( file )
end
--[[
<map>
    <map>
        <map-dinner>
            <object></object>
        </map-dinner>
    </map>
</map>
]]

 

I am going to add a bug report.
