Good question. I am not sure of anything, 100%. I just go by what I read on the forums or in game, or what I interpret the C++ code to say.
This is from command.cpp:
Code:
command_add("makepet","[level] [class] [race] [texture] - Make a pet",50,command_makepet)
Which makes your statement correct. But, when you type #makepet in game with no params, the Usage says:
Code:
c->Message(0, "Usage: #makepet pet_type_name (will not survive across zones)");
And I can say with confidence, lately, if I do not enter the exact name from npc_types table for the pet, linked to the Pets table, I get told cannot find a pet of that type. Not really sure what's up with that.
