It's really only useful for an aesthetic, but in the neverending quest to find new ways to mess with engineers in Freak Fortress 2, I figured out this hidden prop:

		// force the angle now
		new angleOffsetB = FindSendPropInfo("CObjectSentrygun", "m_iAmmoShells") - 16;
		new angleOffsetA = angleOffsetB - 12;
		SetEntDataVector(sentry, angleOffsetA, Sentry_CurrentAngle[sentryIdx]);
		SetEntDataVector(sentry, angleOffsetB, Sentry_CurrentAngle[sentryIdx]);

A couple things to keep in mind:
- It needs to be done every frame or a sentry will slowly revert to the closest target.
- The gun will fire normally only if the closest target is within a certain angle deviation from its reticle.
- Wrangler will either completely block this or result in a race condition.

Still, it can be used for fun mods that mess with players...like making the gun always face the engie. My particular use is to have the gun appear to go haywire.

Sentry has a think function, can probably hook post that. Offsets change pretty often, so this won't be stable between major updates.

Probably the other thing you could do is just set the sentry's target netprop to some entity and then teleport that around. i think that's how the wrangler works

[sarysa]

Maybe. I'd imagine that the sentry would retarget away from a BS target (i.e. same team) pretty quickly, though. Chance of success of firing at this target I'd imagine would be pretty low.

As far as offsets go, since it's a vector, there's only 4 bytes between it and the closest named netprop...it bodes well for its long-term viability. Not to mention it's one of the oldest sentry variables around. It probably has a datamap entry too, but I'm too lazy to figure out which vector it is. :p

Are you sure about this? Last time I tried to hook the think function, I had to manually set the m_nNextThinkTick netprop on the sentry to get it to actually "think".

Nope, i'm not sure at all, and sometimes valve randomly decides to add and remove thinks from entities
