Drone Help

[Mattdaman]

Hi, I need help getting an expression for expression 2 to make a drone that can move forward, back, side to side, and look at the angle you are looking at, purly by vector thrusters. If you were a help enough, I would give you a cookie , if I could...

Lol what is this vector thruster fetish everyone is having :P

[Echo51]

A fetish i assume..

Matt, go try, and fail, then come for help with the problem you have, DO NOT ask for code

[adadr]

i'm not sure if you could do look angles with vector thrusters...if so it would be hard. you could do vector thrusters to go to the position and apply angular force to look id say it the easiest way. no code handouts sry.

[Echo51]

Applyforce all the way is ofcause the easiest adadr

[Mattdaman]

Yeah, maybe I should use apply force, but I have no idea why that did not hit me using the idea using apply force on it though.

[adadr]

lol thanks if i helped if you need help with applyforce Maso has a great tutorial thats how i learned.

[Mattdaman]

I don't understand though (since I am new to the wiremod forums), why won't people handout codes when you ask for them?

[Mattdaman]

Okay, ignore the last line, I found out why you should not give out codes for help, LOL.

Giving out code is a personal choice that several choose not to ever do, but there are a few like me who just want to code something . Thank you for asking for the code, this was actually fun to do because it was a bit challenging.
To make it work paste the expression on something, put 4 vector thrusters on it (location doesn't matter much), use the "Expression 2 - Wirelink" gun on each VThruster and then wire each wirelink input to a VThuster. Feed it a vector to stay at and an angle to face.
