Hi Thomas, oups sorry, I forgot to describe my problem. yes it compiled, didn't crash. it just sended data that didn't correpond to the gem_state struct. Indeed i found my error: I read that gem_state is followed by 2 pointers : gem_state <*GemCache> <*GemState> If I replace in my code GetPointer(argv[0]) by GetPointer(argv[1]), everything is ok. J.Y.

Hi, I'm triing to write a flext external thats reads a gem_state struct. I 'd like to access the pixBlock data. I wrote the following method ( registered as FLEXT_ADDMETHOD_(0,"gem_state", gem_state) ) I don't know where I am wrong in my code.... any hint ? thanks, Jean-Yves
void my_flext_external::gem_state(int argc, t_atom *argv) { GemState *my_pointer; if (CanbePointer(argv[0])) { my_pointer = (GemState *) GetPointer(argv[0]); // retrieve gem pointer if (!my_pointer) { post ("no pixblock !"); return; } else { //accessing to fields post ("dirty field = %d", my_pointer->dirty); post ("inDisplayList field = %d", my_pointer->inDisplayList); post ("lighting field = %d", my_pointer->lighting); post ("texture field = %d", my_pointer->texture); post ("*image field = %d", my_pointer->image); post ("*texCoords field = %d", my_pointer->texCoords); post ("multiTexUnits field = %d", my_pointer->multiTexUnits); // etc... }
