Anti-Gravity Vehicle Controls and Acceleration
Hi there, I've been haveing some trouble with controlling my vehicle. I'm working with an anti-gravity craft that can't fly, but doesn't rely on friction with the ground for movement. I almost have my controls working, but what I really need is to be able to rotate the ship along the ship's Y and Z axes with MouseX, and make its speed gradually accelerate as Input Vertical postive is held down, as well as use inertia to prevent instant stopping, and create gradual slowdowns. I've been using a mixture of an edited MouseLook, and another edited script from the site, but there must be a way to accomplish these tasks in a single script. For reference I have included the two scripts I'm using.
// A very simplistic car driving on the x-z plane. var speed = 10.0; var rotationSpeed = 100.0; static var acceleration : float; static var niceMouseDelta : float ;
function Update () { // Get the horizontal and vertical axis. // By default they are mapped to the arrow keys. // The value is in the range -1 to 1 var translation = Input.GetAxis ("Vertical") speed; var rotation = Input.GetAxis ("Mouse X") rotationSpeed;
// Moves the rigidbody forward along its own z-axis function FixedUpdate () { rigidbody.AddRelativeForce Vector3.forward * 0.1 ; }
// Make it move 10 meters per second instead of 10 meters per frame... translation = Time.deltaTime; rotation = Time.deltaTime;
// Move translation along the object's z-axis transform.Translate (0, 0, translation); // Rotate around our y-axis transform.Rotate (0, 0, 0); }
And...

using System.Collections;
/// MouseLook rotates the transform based on the mouse delta. /// Minimum and Maximum values can be used to constrain the possible rotation
/// To make an FPS style character: /// - Create a capsule. /// - Add a rigid body to the capsule /// - Add the MouseLook script to the capsule. /// -> Set the mouse look to use LookX. (You want to only turn character but not tilt it) /// - Add FPSWalker script to the capsule
/// - Create a camera. Make the camera a child of the capsule. Reset it's transform. /// - Add a MouseLook script to the camera. /// -> Set the mouse look to use LookY.
