That would be great.
Currently on my Ninja Bike i have the left and right tilt animations set to the CW and CCW arm rotation animations.
Hopefully there's a way to make the thing you're mounted on play animations when the client presses keys.
Most key presses are only detected client side.
Especially when mounted to vehicles.
When mounted to stuff, the server doesn't even register the crouch key.
Normally.
But then we have HeightControl that comes with a client that sends the server a command that some guy activated his crouch.
Basically, i am rewriting most of the code for it to fix some stuff AND make it more useful for other modders to use it to detect trigger usage of drivers/mounted people.
I still have to finish the last bits (client sided replication of adding height and finishing up the whole function calling and stuff for the trigger usage of mounted people) and then i will put up a beta for a week to check if everything works out (and give modders time to prepare their mods for the update).
Not sure how long it will take.
It is gonna get pretty busy this week sadly.
