EQEmulator Forums - Prevent Merchant From Buying

This is an old snippet of code I copied from somewhere on these forums, long ago. (I don't remember where)
I never got around to trying it out until now, but I just tested it out and it works awesome. I simply set the
(vendor->GetSTA() == 999) which I set the STA to 999 on the custom merchant NPC. This comes in real
handy for a custom vendor that you don't want players selling all their vendor trash to and making it hard for
others to shop. A client will still get that infamous message "I will give you xxx plat....", but also get a msg,
"I am not interested in that....." So whoever wrote this, Thank YOU !!!

In client_packet.cpp

Code:

// EDIT NOTE: add the parts inbetween //CUSTOM Will STOP a merchant from buying (with GetSTA value)
