Hi,

I have tried using the helper functions used in the PluginSkeleton and other plugin examples but they do not seem to have a method that supports returning something like std::vector<std::vector<float> >, a vector of vectors.

What would be the best way to return a vector of vectors from a c++ plugin to a Lua script?

Thanks,
Rodrigo

Hello Rodrigo,

you can do this if you use the stack functions. The plugin skeleton project also illustrates a callback function that uses the stack functions: LUA_GETDATA_CALLBACK
In pseudo code, you would do something like:

• simPushTableOntoStack(stackId)
• for i=1,arrayCnt do
• simPuckInt32OntoStack(stackId,i)
• simPushFloatTableOntoStack(stackId,array,count)
• simInsertDataIntoStackTable(stackId)
• end.

Cheers
