GrassLoader missing setHeightFunction

I'm in the process of upgrading MV3D from a very old version of Python Ogre (1.1 I think) to 1.6.1. It seems like in 1.6.1, there is no way to set a height function for a GrassLoader. The setHeightFunction method doesn't seem to be wrapped. Am I missing something here?

Thanks,

Mike

Hijacking my own thread here. Another issue I found while upgrading is that it seems like the autoconversion from MemoryDataStream to DataStream isn't working any more. This code works fine with older versions of Python-Ogre:



fil = open("some.material")

data = fil.read()

fil.close()

sctyp = ctypes.c_char * len(data)

cpy = sctyp(" ")

for pos in range(len(data)):

    cpy[pos] = data[pos]

dst = Ogre.MemoryDataStream(Ogre.CastVoidPtr(ctypes.addressof(cpy)),

    len(data))

Ogre.MaterialManager.getSingleton().parseScript(dst, "General")

But in 1.6.1 gives the following exception:



Traceback (most recent call last):

  File "F:\Projects\MV3D\branches\354-upgradeogre\mv3d\test\test_asset.py", line 146, in test_readyAsset

    asset.readyAsset()

  File "F:\Projects\MV3D\branches\354-upgradeogre\mv3d\resource\ogre3d.py", line 302, in readyAsset

    Ogre.MaterialManager.getSingleton().parseScript(dst, "General")

Boost.Python.ArgumentError: Python argument types in

    MaterialManager.parseScript(MaterialManager, MemoryDataStream, str)

did not match C++ signature:

    parseScript(struct MaterialManager_wrapper {lvalue}, class Ogre::SharedPtr<class Ogre::DataStream> {lvalue} stream, class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > groupName)

    parseScript(class Ogre::MaterialManager {lvalue}, class Ogre::SharedPtr<class Ogre::DataStream> {lvalue} stream, class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > groupName)

Can you upgrade to the 'latest' version of Python Ogre and see if it solves your issue -- basically install 1.6.1 and then overwrite the installation with the files referenced here

Thanks

Hi Andy,

I knew I was missing something. That did fix the DataStream/MemoryDataStream issue, but it still seems like setHeightFunction is missing from GrassLoader:



File "F:\Projects\MV3D\branches\354-upgradeogre\mv3d\client\ui\ogre3d.py", line 758, in create

  self.object.setHeightFunction(OgreGrass, "getHeight")

exceptions.AttributeError: 'GrassLoader' object has no attribute 'setHeightFunction'

Probably not as big of a deal as the other issue since I can just turn off grass for anyone using Python-Ogre 1.6 for now.

Thanks,

Mike
