You can use "EditObject(playerid, objectid)" if you SA-MP's native "CreateObject" function or you can use "EditDynamicObject(playerid, objectid)" for if you use streamer's native "CreateDynamicObject" function. Then, when you hit the save icon, it will then be called under "public OnPlayerEditObject(playerid, playerobject, objectid, response, Float:fX, Float:fY, Float:fZ, Float:fRotX, Float:fRotY, Float:fRotZ)" if you use SA-MP's system or it will be called under "public OnPlayerEditDynamicObject(playerid, objectid, response, Float
, Float:y, Float:z, Float:rx, Float:ry, Float:rz)" if you use streamer's system.
I hope that doesn't sound too complicated, just ask if you don't understand a certain part.
