Summary0000820: Client-side prediction for ThrustThing/ThrustThingZ/A_Recoil specials when called from linedefs/sector action things/weapons
Description
Quote from Torr Samaho
Quote from ant1991331
If anyone's ever noticed, that if you play a server with a noticeable ping, that makes use of A_Recoil and the like, it will be very laggy.
So I'm thinking if Thrust movements can be clientside, it would be much like ordinary player movement (how it's only laggy to you when you get "connection interrupted"). I even notice this lag on jump pads, but I dunno if that uses ThrustThingZ.

I still see a chance to get Thing_Thrust_Z player prediction working for line and sector actions (but not for ACS).

IMHO, I think it's about time we get some proper client-side prediction for these specials.
Steps To Reproduce1. skulltag.exe -file thrustthing_recoil_01.wad -host
2. Connect a client to the server with an emulated ping of 300-600 and join the game.
3. Use the custom pistols and jump-pads.
4. Press +use to teleport back to the jump-pads.

I started to work on ThrustThing/ThrustThingZ prediction specials when called from linedefs. Please check how well the current version works.

Confirmed that this is working better. The left pads of the two always work instantly, whereas the right of the two pads lags. I assume the left two are set to use the clientside prediction (which work instantly)? If so, then this is fixed.

Like Watermelon said, it seems to work well. Great job, Torr. Keep it up.

The "right" pads use sector actions, that's why they are not predicted in the binary above. Meanwhile I extended the prediction to also handle sector actions, so this binary should predict all pads in the example map. I had to touch some basic code though, hope this doesn't break any sector action related things on the clients.

This is really great, Torr. Finally, after all these years we finally have some working prediction for these specials. I'll be testing IGPack and SpaceDM9 now. They play really well online now.

Does this need any more testing? Or any way I can help?
