Camera judders when I press jump in midair
I'm a total beginner at Unity but I managed to frankenstein together a mostly functional 3D Player Controller script including jumping, camera following the player and the player moving and rotating relative to the camera position. However if I hit the jump (space) button while the player gameobject is in midair the camera suddenly jumps upwards. Every fix I tried prevented the player from jumping at all while a direction is pushed. Could someone please help?
void Move(float lh, float lv, float jmp)
{
movement.Set(lh, jmp, lv);
movement = Camera.main.transform.TransformDirection(movement);
bool isGrounded = CheckGrounded();
// Check if the player is pressing the jump key
if (jmp > 0f)
{
// Make sure we've not already jumped on this key press
if (!pressedJump && isGrounded)
{
// We are jumping on the current key press
pressedJump = true;
// Jumping vector
Vector3 jumpVector = new Vector3(0f, jumpSpeed, 0f);
// Make the player jump by adding velocity
playerRigidBody.velocity = playerRigidBody.velocity + jumpVector;
}
}
else
{
// Update flag so it can jump again if we press the jump key
pressedJump = false;
}
$$anonymous$$ight need a bit more info to help out. Where is your camera in the hierarchy? Where is this $$anonymous$$ove() function being called?
Move is being called in FixedUpdate (I'm not 100% sure whether that's the right option compared to just Update):
void FixedUpdate()
{
float lh = Input.GetAxisRaw("Horizontal");
float lv = Input.GetAxisRaw("Vertical");
float jmp = Input.GetAxis("Jump");
Move(lh, lv, jmp);
}
For the camera I'm using a script grabbed from elsewhere:
using UnityEngine;
using System.Collections;
public class SmoothFollow : MonoBehaviour
{
// The target we are following
public Transform target;
// The distance in the x-z plane to the target
public float distance = 10.0f;
// the height we want the camera to be above the target
public float height = 5.0f;
// How much we
public float heightDamping = 2.0f;
public float rotationDamping = 3.0f;
// Place the script in the Camera-Control group in the component menu
[AddComponentMenu("Camera-Control/Smooth Follow")]
void LateUpdate()
{
// Early out if we don't have a target
if (!target) return;
// Calculate the current rotation angles
float wantedRotationAngle = target.eulerAngles.y;
float wantedHeight = target.position.y + height;
float currentRotationAngle = transform.eulerAngles.y;
float currentHeight = transform.position.y;
// Damp the rotation around the y-axis
currentRotationAngle = Mathf.LerpAngle(currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);
// Damp the height
currentHeight = Mathf.Lerp(currentHeight, wantedHeight, heightDamping * Time.deltaTime);
// Convert the angle into a rotation
var currentRotation = Quaternion.Euler(0, currentRotationAngle, 0);
// Set the position of the camera on the x-z plane to:
// distance meters behind the target
transform.position = target.position;
transform.position -= currentRotation * Vector3.forward * distance;
// Set the height of the camera
transform.position = new Vector3(transform.position.x, currentHeight, transform.position.z);
// Always look at the target
transform.LookAt(target);
}
}
The only change I made to the MainCamera in the Hierarchy is adding this script component and its variables and setting the tag to MainCamera
