Module expanders tutorial?

but I think for a given direction of communication you always have to declare an array of 2 elements of the buffer you wish to use

That’s interesting. I think that I may be essentially doing the same thing when I assign the structures like:

// defined as class variables
GrainEngineExpanderMessage *producer_message = new GrainEngineExpanderMessage;
GrainEngineExpanderMessage *consumer_message = new GrainEngineExpanderMessage;

// Assigned in the constructor
leftExpander.producerMessage = producer_message;
leftExpander.consumerMessage = consumer_message;

The above is code that is successfully running in my GrainEngineMK2 expander. Here’s a thread where the author takes the same approach:

Expander: custom object?

Hi, is it possible to pass a custom object on the buffer instead of arrays? Trying to do this: struct MyValues { float mValue1; float mValue2; MyValues() : mValue1(1.0f), mValue2(2.0f) { } }; std::array<MyValues, 2> leftMessages; but when I connect the void*, it can’t cast: leftExpander.producerMessage = leftMessages[0]; leftExpander.consumerMessage = leftMessages[1]; is it possible? What’s the best practice? I’ve some data which is not always “array of float” Thanks

This is all starting to come back to me, so I may be able to sort this out tonight, or at least bring some more specific questions.

Perhaps one question is – am I supposed to be reading from leftExpander.consumerMessage? This might be something I’ve been doing wrong. ooohhhhhh… I think it’s starting to all make sense. I’ll work on this again tonight!
