need help on adduservariable()

Recommended Posts

GB_AttributeRef POP_ContextData::addUserVariable ( const char * name,

int size,

GB_AttribType type,

const void * def,

const char * local = 0


There is no description or example file for this. Can someone give an example?


here's an example

OP_Context &context;

POP_ContextData* data = (POP_ContextData*) context.getData();

float def[4] = {0};

data->addUserVariable( "test", sizeof(float), GB_ATTRIB_FLOAT, def );

this will add a single float (as an attribute) to each particle.

not sure what the last param of local is meant for -- perhaps as a default for strings?
