Hola
This code is used to prevent the accidental sale or deletion of objects. You can use this 'system' for a quick sale system at NPC. I saw this system on another server, I recoded it myself. Mine works by performing SHIFT + Double click. I give it for free because I think it's very useful and I would like to see it more often on the servers.

IsUsableItem isn't for dog, use it.
Call it before you use pItemElem.

Look at the body of the method before giving advice, disrespectfully in addition. Thanks. :handsdown:

03/24/2020 07:14 Seigh77#4

have problem with the

pItemElem->SetFlag(CItemElem::locked, bLock)

the error is
CItemElem::SetFlag function does not take 2 arguments :)

thank you for this release

Thank you for posting, does this require a bank password?

thank you for this release

Because he change the SetFlag function to add a BOOL "bLock".
Hard to use SetFlag for "lock" and ResetFlag for remove "lock".

It is good to use IsUsableItem on the CUser::LockItem, but you have to use it also on CDPSrvr::OnLockItem.

Code:

void	SetFlag(BYTE byFlag, BOOL bEnable = TRUE) { if (bEnable) m_byFlag |= byFlag; else m_byFlag &= ~byFlag; }
