Players' parachutes sometimes do not deploy

[cmbasnett]

I've experienced this first hand on Vierville and have seen many other players complain about this. Seems to have something to do with lag and/or players switching weapons while they're jumping out of the planes.

Rule of thumb: Don't sprint while parachuting, don't switch weapons while parachuting, and don't sprint right after landing from a jump.

This is definitely a problem with certain users, there was one guy who kept falling to his death over and over. I've never had this happen and most users don't have it as well.

Well, as far as I remember, when one parachutes, his weapon is forcibly switched to parachute. I guess this "bug" happens because something is preventing inventory switch. (For example, we all know that one can't switch weapons while sprinting) May be making a ForcedInventorySwitch(), that will bypass all checks, and use it to force parachute as the current used item to the player will solve this issue. Another thing you should know is that: in the event of lag/packetloss, when player spawns he will not receive his "loadout" properly. You just spawn with bare hands, and if you attempt to switch weapons you get the message that shows the name of the weapon (the one you get when cycling your weapons), but you still won't see any weapon mesh in your hands, wont be able to shoot etc. etc. (A DH 6.0 specific inventory bug I often have: I spawn, get primary, but no ammo is added-HUD shows zero magazines. Switchin weapons won't help).

May be this has something to do with the Inventory Check that is called when player spawns. Most likely not, because using weapon mutators that call this check every Tick() do not prevent this bug from happening. Or may be those experiencing this bug just have poor connection to the server most of the time. Another bug I have seen with these chutes is a vertical jerkiness of the whole parachute mesh. Or no parachute mesh is drawn at all (player drops fine).

Possibly part of this issue is after successfully parachuting to the ground, you are not switched from the parachute item and are not able to switch from it. When you look up you can still see the parachute model above you while you run around. Your weapon cannot be shot out of your hand, you cannot drop the parachute, and jumping does nothing to fix the issue. Basnett seems to think this issue wasn't always around or at least not a prominent and it may be a result of a refactor of code at some point in time.
