Unity relative velocity limiting
Ive been working on a 3d first person and need to have velocity limiting. The player is rotated with the mouse, this caused issues as I need the velocity to be slowed based of the player object's x and z axis not the world x and z axis, however there is unfortunately no function for this
here is my code: using System.Collections; using System.Collections.Generic; using UnityEngine;
public class Player : MonoBehaviour {
//player speed
public float speed;
public float jumpPower;
public float velLimit;
//velocity limiting;
private Vector3 relativeVel = new Vector3(0, 0, 0);
// looking
private float rotY = 0;
public float mouseSensitivity;
//body
public Rigidbody rBody;
//keys
public KeyCode left;
public KeyCode right;
public KeyCode forward;
public KeyCode backward;
public KeyCode jump;
void Update () {
//velocity limiting
relativeVel = transform.TransformDirection (rBody.velocity);
if(relativeVel.x > velLimit){
Vector3 vel = new Vector3 (velLimit, rBody.velocity.y, rBody.velocity.z);
rBody.velocity = vel;
}
if(relativeVel.z > velLimit){
Vector3 vel = new Vector3 (rBody.velocity.z, rBody.velocity.y, velLimit);
rBody.velocity = vel;
}
//negative
if(relativeVel.x < -velLimit){
Vector3 vel = new Vector3 (-velLimit, rBody.velocity.y, rBody.velocity.z);
rBody.velocity = vel;
}
if(relativeVel.z < -velLimit){
Vector3 vel = new Vector3 (rBody.velocity.z, rBody.velocity.y, -velLimit);
rBody.velocity = vel;
}
//movement
if(Input.GetKey(left)){
Vector3 leftMove = new Vector3 (-1 * speed, 0, 0);
rBody.AddRelativeForce (leftMove);
}
if(Input.GetKey(right)){
Vector3 rightMove = new Vector3(1 * speed, 0, 0);
rBody.AddRelativeForce (rightMove);
}
if(Input.GetKey(forward)){
Vector3 forwardMove = new Vector3(0, 0, 1 * speed);
rBody.AddRelativeForce (forwardMove);
}
if(Input.GetKey(backward)){
Vector3 backwardMove = new Vector3(0, 0, -1 * speed);
rBody.AddRelativeForce (backwardMove);
}
if(Input.GetKeyDown(jump)){
Vector3 jumpMove = new Vector3(0,jumpPower,0);
rBody.AddRelativeForce (jumpMove);
}
//looking
rotY += Input.GetAxis ("Mouse X") * mouseSensitivity;
Vector3 rot = new Vector3 (0, rotY, 0);
transform.eulerAngles = rot;
}
}
