Writing to focus/mouseover WGUID

[reggggg]

Hi,

Am currently writing something where I would like to cast a spell (no gcd, instant) on a target without having to use injection - for simplicities sake at this time.

My current plan is to write to the focus or mouseover WGUID and then simply press a bind for a macro with @focus in it etc.

Is there anything inherently unsafe about this approach? I am new to this and would very much like to know if there is any checksumming or similar going on that I should be wary of.

Thanks!

Well, I decided ' **** it ' and did it anyway, works great.

Good call, since there are no such mechanisms in place. It would also be troublesome to do any kind of checking on stuff like the mouseover guid in Warden itself. If anything, they will make you work harder to spoof its value in the client. (note: this is in its entirety a hypothetical scenario, experience says they won't ever employ any advanced generic detection mechanisms)

Note that there used to be a few cases where just setting the mouseover guid didn't work. If you look for where the MO guid is set, there's a function that sets it and then calls another function which I believe updates the unit highlight status (not 100% sure on that, but that's my guess). There used to be at least one case where you had to also call the update highlight function after manually poking in the guid.

But other than that, yah, setting the MO guid and calling functions against it is a very cheap and hard-to-detect method to act against arbitrary wow targets.
