Aura data

Kayen · #1 08-09-2012, 10:45 PM

Data I collected about the 'aura' effect, which when cast populates the aura window and spawns an invisible NPC that grants an effect to the group within the proximity.

This is the information I have so far. I don't have any experience really dealing with opcodes and that part of the source. So not really able to proceed any further to implement it at this time. If anyone more capable is able to package this information into usable functions I would be more then happy to finish the job.

Thanks to Trevius for helping to figure out the struct.

Code:

struct Aura_Struct
{
/*000*/ uint32 type;                // Seen 0, 1, or 2
/*004*/ uint32 entity_id;   // Entity ID for deletes or 1 for new auras
/*008*/        char aura_name[64];        // Name of the Aura
/*072*/        uint32 entity_id2;        // Entity ID for new auras
/*076*/        uint32 unknown 76;        // Seen 133
/*080*/        
};
