would it be possible to make car actually drive to you when using keys ?
That may be difficult if the player is on another surface than the car. Teleporting is the only way to get it to you. Also, what about locked cars? They wouldn't be able to come to you in that case.
cos that teleport thing with keys is kinda cheaty and main reason i dont use GCKI , it also make other mod i really like vehicle wagon useless... why trouble yourself with loading/unloading on wagon when you can teleport your vehicle everywhere ?
I agree, this isn't relevant in single player, but in multiplayer, it serves as protection against griefers: Nobody can make your car disappear with everything inside by loading or unloading it from a vehicle wagon. Vehicles claimed/locked with GCKI may only be loaded/unloaded by the owner or the player who locked them. All other vehicles can be loaded/unloaded by anybody.
Also, thanks for the compliment … :-)
