Lately a game that I usually look after for news about it's development called BeamNG.Drive made a very clever idea of creating a simple App that allows you to have full control of your vehicle by using the gyroscope sensor on the phone and it looks really fun.
https://www.youtube.com/watch?v=O7nTnhLbbDYSo I thought what if we create something similar, a Remote App for Blockland with different functions and features?
With vehicles it could have a similar support that works with the mouse steering, since using the mouse steering we have full control of the steering of the vehicle, and if we implement a phone app that basicly controls it like you're using a mouse on your computer but recalibrated with the gyroscope sensor of your phone we could have a similar looking support on the one you can see on the video.
And if we get crazier, we could use the phone to help with the building process as well remotely, but how? Maybe by adding a bricks list that you can use by letting your phone on the table and touch the brick you want to use and it's transfered for your blockhead's inventory on the fly without having to open the menu in-game, it also could be helpful to give your character any item you need without wrenching from a brick and getting the item, the app could also have an items list, and both lists could be updated in your application depending on which add-ons you have on your game, so if you want to get a community made add-on of a weapon and send it over to your character just go on the items list, search on the weapons category and click it.
The App could also have an Admin Tool that is unlocked if you're detected as an admin on the server you're currently in, it gives you all the commands you need as an admin of a server, just get your phone, find what you need to do for example banning a bad player, and you can ban someone from your phone, also let's say you're away from the computer and your server is getting "attacked" by a bad user which is ruining the experience for the other players, the app could also have notification support that notifies you if anyone on the server reported a bad player, the players should use a command with the name of the troublesome user and a text to explain why.
Don't want to leave the server you're currently in so you can check the servers list? Why not use the phone and look at the Servers List option to see what server it can catch your attention? If you find something you're interested, just click on the server to join, and your game will automaticly transfer you to the server you selected on the phone.
Want to change your look? The App could have a Change Appearance option that allows you to change your look on the fly and remotely that also can transfer your new look to your in-game character.
I know this might be hard work, so atleast one of those things could be cool, the vehicles thing would be fun I believe.
