Structure access

get<struct>[<id>].<member> <gamevar>
set<struct>[<id>].<member> <value>
get<struct>var[<id>].<gamevar> <gamevar>
set<struct>var[<id>].<gamevar> <value>
getuserdef .<member> <gamevar>
setuserdef .<member> <value>

The get commands fetch one of the members of a structure into a gamevar.

The set commands assign the value provided to the member.

The commands with the "var" suffix are used to access custom members for a struct, which are really just that ID's gamevars which have the per-<struct> flag set. So setactorvar[THISACTOR].temp 0 is the same as setvar temp 0.
