Launching player with cannon

Make an animation, parent character to the animated root (and disable character movement etc) for the duration of the animation.

If you want something physics driven, you might want to add a rigid body to the object, disable any character movement scripts, call rigidbody.AddForce with the direction you want to fire it and use force mode impulse. Upon collision you might want to disable the rigidbody and reactivate the character again.

I spent about 3 days trying to make this script, now that I got it, it has worked well in my project. Here he goes to help anyone looking for the same thing. Remembering that it is for 3D games.

 using System;
 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 
 public class PlayerControlCannon : MonoBehaviour
 {
     public Rigidbody character;
     public Transform shootingPart;
     public bool manualControl;
     public float rotatingSpeed = 100f;
     public float shotForce = 50f;
 
     private bool isShooting = false;
     private float backColliderDelay = 0.05f;
 
 
     public void Start()
     {
 
     }
 
 
     public void Update()
     {
 
         if (Input.GetButtonDown("Fire1") && isShooting == true)
         {
 
             StartCoroutine("Shooting");
 
             print("Fired");
 
         }
     }
 
     IEnumerator Shooting()
     {
 
         character.transform.position = transform.position;
         character.transform.rotation = shootingPart.rotation;
 
         character.AddForce(transform.forward * shotForce, ForceMode.VelocityChange);
 
         character.transform.parent = GameObject.FindWithTag("Player").transform;
         character.GetComponent<MeshRenderer>().enabled = true;
         character.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.None;
         character.GetComponent<Collider>().enabled = false;
 
         yield return new WaitForSeconds(backColliderDelay);
 
         character.GetComponent<Collider>().enabled = true;
 
         isShooting = false;
 
     }
 
     public void OnTriggerStay(Collider other)
     {
         if (other.gameObject.CompareTag("Player"))
         {
 
             other.gameObject.transform.parent = transform;
             other.gameObject.transform.localPosition = new Vector3(0f, 0f, 0f);
             other.gameObject.transform.localRotation = Quaternion.identity;
             other.gameObject.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezeAll;
             other.gameObject.GetComponent<MeshRenderer>().enabled = false;
 
             isShooting = true;
 
         }
 
         if (manualControl == true)
 
         {
             // Move to the right
             if (Input.GetButton("Horizontal") && Input.GetAxisRaw("Horizontal") > 0)
             {
                 transform.Rotate(Vector3.up * rotatingSpeed * Time.deltaTime);
             }
 
             // Move to the left
             else if (Input.GetButton("Horizontal") && Input.GetAxisRaw("Horizontal") < 0)
             {
                 transform.Rotate(Vector3.down * rotatingSpeed * Time.deltaTime);
             }
 
             // Move to the up
             else if (Input.GetButton("Vertical") && Input.GetAxisRaw("Vertical") < 0)
             {
                 transform.Rotate(Vector3.right * rotatingSpeed * Time.deltaTime);
             }
 
             // Move to the down
             else if (Input.GetButton("Vertical") && Input.GetAxisRaw("Vertical") > 0)
             {
                 transform.Rotate(Vector3.left * rotatingSpeed * Time.deltaTime);
             }     
         }
     }
