"Skip vendor run, mount Traveller's Tundra, use vendor. Continue."

[lofi]

I attempted to do this by adding one of the mammoth vendors to the profile and putting the location in a safe area. Then wrote a plug-in that would detect if you were in a short range of the safe spot and use the tundra mammoth.

WoWPoint vendorLocation = ProfileManager.CurrentProfile.VendorManager.AllVendors[0].Location;
float myDistance = Me.Location.Distance(vendorLocation);

// if bot is within 5 yards of the "vending spot"
if (myDistance < 5)
{
    if (!Me.Buffs.ContainsKey("Traveler's Tundra Mammoth"))
    {
        // Cast Tundra Mammoth !!
        Mount.MountUp();

        // Wait for spell cast
        Thread.Sleep(1500);
    }
}

Although the vendors appeared and the bot was standing in the right spot it would not interact with any of them. I think this is not possible to do currently without changes to Honor Buddy application.
