==Project Summary==
Roller is a community made software developed by Spooner to convert and process {{ofp}} and {{arma1}} island files.


Roller is a community made software developed by Spooner to convert and process OFP and ArmA island files.
Its primary purpose is to convert {{ofp}} islands to {{arma1}} for the ACE Island Pack, but it can also do some processing that could be useful to people making new {{arma1}} islands.

===Visitor 3===
 
The conversion process is very simple and only takes a few minutes. The goal is to have as much as possible automated, so that only these tasks remain:
 
'''1)''' Read the 4WVR/8WVR WRP with Roller and set the correct params for Roller. Normally you at least need "-x -O -u".
 
'''2)''' Get the ''XYZ file'' (elevation data). Get the ''objects file'' (all objects of the map). X, Y, Z position and orientation are exported for each object. Unfortunately v3 cannot import object scale. Also the object orientation is 2d only (N/E/S/W. No 3rd dimension: pitch).
 
This fact does not really hurt though. Both are normally only applied on vegetation and you can easily recreate a similar look via v3 random object scale and pitch functions.
 
'''3)''' Create a new project in v3 with the right dimensions and cell size (OFP default 50 meters). For more details or information about SAT settings consult the [[Visitor_3_Manual|Visitor 3 Manual]].
 
<br clear="all" />
[[Image:V3_Project_Parameters.jpg|thumb|250 px|Project parameters in Visitor 3|left]]
<br clear="all" />
 
'''4)''' Import the XYZ file to get the actual terrain.
 
<br clear="all" />
[[Image:V3_Import_XYZ.jpg|thumb|250 px|Import XYZ in Visitor 3|left]]
<br clear="all" />
 
'''5)''' Import one ore more ''object template PEWs''. To be able to import objects from object template files v3 needs to know the model and its path. Fortunately the information about models is saved in a PEW and you can import that definition in your PEW from another PEW.
 
You can download ''object list template PEW'' that includes all OFP, ArmA objects, as well as some ACE island pack objects. More details on object template definition in general and the ACEIP objects below.
 
'''6)''' Import the object template(s).
 
<br clear="all" />
[[Image:V3_Import_Object_Templates.jpg|thumb|250 px|Import object templates in Visitor 3|left]]
<br clear="all" />
 
'''7)''' Import the island objects from the objects file generate by Roller. If not done already, you need to add the ''ImportObjects.vis'' script to visitor 3 first. You will find the file in the ''.\visitor 3\scripts'' folder.
 
<br clear="all" />
[[Image:V3_Import_Objects_Scripts.jpg|thumb|250 px|Import objects in Visitor 3|left]]
<br clear="all" />
 
'''8)''' Load the terrain with buldozer and export the island to 8WVR WRP. You need to have buldozer loaded, switch back to v3 and select export world.
 
<br clear="all" />
[[Image:V3_Export_World.jpg|thumb|250 px|Start buldozer and export world to a WRP file in Visitor 3|left]]
<br clear="all" />
 
Done. This course of action takes only a couple of minutes.
 
===Details===
 
====Objects====
 
The island most likely has OFP object addons. These do not exist in ArmA. We have to differentiate between OFP and Resistance objects that came with the game and community made objects. There are a few different options here now.
 
=====Object replacement=====
 
Roller has the option to replace objects with the param '''--replace-objects'''. The mapping is defined in a so called YAML file. It is a standard text file.
 
--replace-objects ofp_ace_objects.yaml,ofp_arma_objects.yaml
 
You need to supply the param with at least one YAML file. If you attach multiple YAML files, they will be processed sequentially one after another.
 
An object replacement YAML mapping file looks like this:
 
data3d\afbarabizna.p3d:
  -
    :name: ca\buildings\afbarabizna.p3d
    :offset: [0, 0, 0]
data3d\afdum_mesto2.p3d:
  -
    :name: ca\buildings\afdum_mesto2.p3d
    :offset: [0, 0, 0]
 
# pathToFile\nameOfFile.p3d:
#  -
#    :name: pathToReplacementFile\subfolder\nameOfReplacementFile.p3d
#    :offset: [X, Y, Z]
 
Via the offset you can move the object in meters in any direction you want to.
 
The YAML file needs to be located in the same location as TODO.
 
For an 1:n replacement define the object mapping in the YAML like this:
 
data3d\oliva.p3d:
  -
    :name: ace_vegetation_obj\m\tree\ace_akat02.p3d
    :offset: [0, 0, 0]
  -
    :name: ace_vegetation_obj\m\tree\ace_javor01.p3d
    :offset: [0, 0, 0]
 
An n:1 mapping is replacing any object with one and the same of course.
 
n:1 means ''make object X, Y and Z to object A''.
1:n means ''make object X to either object A or B''.
 
=====OFP to ArmA YAML file=====
 
Roller already has a mapping for OFP and Resistance (NOT community addons, only for core game files) integrated. The name is ''ofp_arma_objects.yaml''. Roller will find the file automatically, if you there is no YAML file called the same way in the TODO location.
 
You can download the ''ofp_arma_objects.yaml'' file [http://www.ofpec.com/ here].
 
Unfortunately there is no (working replacement) for each OFP/Resistance objects. You can either define your own mapping or use the OFP to ACE mapping.
More details in the next paragraph.
 
=====OFP to ACE YAML file=====
 
This is again a mapping integrated into Roller. Same details apply for it how to run it as for the ''ofp_arma_objects.yaml'' file.
 
You can download the ''ofp_ace_objects.yaml'' file [http://www.ofpec.com/ here].
 
The-f made a mapping from OFP to ArmA objects for the objects where a suitable replacement was available. The remaining objects, that have no (working) replacement in ArmA, have been converted to ArmA and are part of the [[ACE:IslandPack|ACEIP]].
 
You can either define your own mapping or use the objects from the ACEIP. Beware that this makes your islands dependent on the addons part of the ACEIP.
 
=====Community made OFP objects=====
 
For custom community made OFP objects you need to define your own replacement. You can either get the permission for the object(s), convert them to ArmA format or replace them with any (suitable) object available in ArmA.
 
If you do not define a mapping, v3 will simply not be able to import the object. So you can just drop objects that way.
 
Note that it is recommended to replace the object with dummy object instead to preserve the object ID numbering of the source WRP.
 
Another option is to replace them with the a very tiny object from ArmA like a flower (TODO: add pathToFile). Note that you will loose the information about the source type of the given object this way.
 
It is better to create a new addon with dummy models in there. Each file has the same path and file naming as the missing object. Instead of the original model you put ''flower.p3d'' in there and rename it to the needed p3d name.
 
This way you keep the information about the correct object type. Once the object will be available in ArmA, you can replace your dummy addon / model with the correct file.
 
It is recommended to name the PBO in a proper way (your own tag and descriptive name) and use the PBOPREFIX to define the original path needed.
 
ACEIP_P_CWC
TAG TYPE p3d NAME
$PBOPREFIX$ data3d
 
Types:
F function
M mission
P p3d
S sound
T texture
W world
 
Finally the ACEIP already contains a good number of converted OFP community object addons.
 
If you make your islands based on the ACEIP, you may not have to do anything at all, but to load the ''[[Tools:Roller#Additional_helpers|OFP 3rdParty object definition template]]'' in v3 before you import the objects.
 
OFP community addons converted by the ACEIP:
* TODO add addon names
 
OFP community addons replaced by a dummy addon by the ACEIP:
* TODO add addon names
 
=====Forest block objects=====
 
OFP used so called forest block objects for forests. It was one model that consisted of several trees and bushes.
 
It is recommended to replace these for an ArmA WRP for performance reasons and forest blocks with partially fly at slopes as ''fit to ground'' cannot be applied in ArmA to the forest block object.
 
Roller offers a great feature to replace the forest block objects with single vegetation objects with the param ''--replace-blocks''. The mapping is defined in a so called YAML file. It is a standard text file.
 
--replace-blocks ofp_ace_forest_blocks.yaml,ofp_arma_forest_blocks.yaml
 
You need to supply the param with at least one YAML file. If you attach multiple YAML files, they will be processed sequentially one after another.
 
A YAML mappings look like this:
 
data3d\les ctverec pruchozi_t1.p3d:
    :sectors: [:N, :E]
    :min: 15
    :max: 30
    :models:
        ca\plants\smrk_velky.p3d: 0.3
        ca\plants\les_singlestrom.p3d: 10
        ca\plants\smrk_siroky.p3d: 0.5
        ca\plants\dd_bush01.p3d: 0.8
 
# pathToFile\nameOfFile.p3d:
#  -
#    :name: pathToReplacementFile\subfolder\nameOfReplacementFile.p3d
#    :sectors: [:orientation, :orientation]
#    :min: minmumNumberOfObjects
#    :max: maximumNumberOfObjects
#    :models:
#        pathToReplacementFile\subfolder\nameOfReplacementFile.p3d: relativeDistribution
 
Sectors defines the orientation of the forest block object. Most forest block objects have a triangular shape. So the orientation defines with sectors of the quadrangle is covered by the forest block object. For a square forest block object all forest possible orientations are listed in the sectors definition.
 
Min and max define the minimum and maximum number of objects Roller should generate in the area.
 
The models section defines which objects should be placed in the area by Roller.
The integer value after each object is added up for the one replacement and is the relative distribution compared to the other objects listed in the models section.
 
The YAML file needs to be located in the same location as TODO.
 
Roller has two forest block object replacement templates integrated. Roller will find the file automatically, if you there is no YAML file called the same way in the TODO location.
 
''ofp_arma_forest_blocks.yaml'' ([http://www.ofpec.com/ download link]) is to replace the OFP forest block objects with ArmA vegetation.
 
''ofp_ace_forest_blocks.yaml'' ([http://www.ofpec.com/ download link])  is to replace the OFP forest block objects with OFP resistance vegetation converted as part of the [[ACE:IslandPack|ACEIP]].
 
=====Object export=====
 
Now that we have defined any possible modifications on objects we can export them to a text file to be able import them in visitor 3 again.
 
The param ''--objects'' exports all objects to a file. If you do not define the name it will default to the name ''WRPFILE_objects.txt''.
 
=====Split object export=====
 
Visitor 3 can only import up to 200 to 250 thousand objects in one go. For more objects visitor will freeze.
 
Therefore Roller also contains the helper tool called '''split.exe'''. It can split the objects export file to multiple smaller ones. You can then import them one after another. By default the files will split into 100 thousand lines each. You can define the number of lines yourself as optional parameter after the specification of the file that you want to split.
 
split.exe WRPFILE_objects.txt 200000
Usage: split.exe FILE [MAX_LINES]
 
=====Unique objects list=====
 
It is very useful to know what kind of objects are present in a WRP. From the list you can make the replacement YAML and identify custom community made objects.
 
 
The param ''--unique-objects'' generates a list of unique objects present in the given WRP. If you do not define the name it will default to the name ''WRPFILE_unique_objects.txt''.
 
=====Special objects=====
 
TODO: bridges, port walls, objects positioned on top of another object.
 
==Additional information==
 
===FAQ===
 
===Possible future changes===
 
===Known issues===
* Trees and bushes generated to replace forest blocks are placed entirely randomly within the area covered by the forest, so they can overlap each other [Not sure this will be very noticeable for players or that any fix won't cause other problems, but if an issue, then it will have to be dealt with].
