How do I Instantiate my shot and make it stay infront of the player before releasing the button.

[Supermacka]

Hey,

I’m building a 2D project where I will have two spaceships that battle to get the most of their own color on the ground (bombit, splatoon, etc. inspired).

I’m stuck at creating a shot mechanic where the player can holds space and the shot Instantiates infront of the player on the “shotPosition” (it charges, gets more powerful while doing this) while the player is moving, until you release the space-button and the shot gets fired away forward.

I have been stuck on this for hours.

Thanks in advance

(On the picture you can see the spaceShip and shotPos).

Here is my code for the movementScript:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player1_Controller : MonoBehaviour {

	//Int and Floats
	public int turnSpeed;
	public float maxSpeed;

	public float defaultPower;
	public float charge;
	public float maxPower;
	public float reloadTimer = 1f;

	private bool isUp = false;
	private bool canShoot = true;
	// Gameobjects and Transforms
	public Transform shotPos;

	// Rigidbody
	Rigidbody2D rb2d;
	public Rigidbody2D shotPrefab;

	// Use this for initialization
	void Start ()
	{
		rb2d = GetComponent<Rigidbody2D>();
	}
	
	// Update is called once per frame
	void Update()
	{
		float yAxis = Input.GetAxis("W_S") * maxSpeed;
		float xAxis = Input.GetAxis("A_D");

		MovementForward(yAxis);
		Turning(transform, xAxis * -turnSpeed);
		Shooting();
	}

	private void MovementForward(float amount)
	{
		Vector2 force = transform.up * amount;

		rb2d.AddForce(force * Time.deltaTime);
	}

	private void Turning(Transform t, float amount)
	{
		t.Rotate(0, 0, amount * Time.deltaTime);
	}

	private void Shooting()
	{
		if (Input.GetKey(KeyCode.Space) && charge < maxPower)
		{
			charge += Time.deltaTime * 30;

		}
		if (Input.GetKeyUp(KeyCode.Space) && canShoot == true)
		{
			Rigidbody2D shot;
			shot = Instantiate(shotPrefab, shotPos.position, shotPos.rotation) as Rigidbody2D;
			shot.AddForce(shotPos.up * charge);

			charge = defaultPower;
			canShoot = false;

		}
		else if (canShoot == false)
		{
			reloadTimer -= Time.deltaTime;

			if (reloadTimer <= 0)
			{
				reloadTimer = 1f;
				canShoot = true;
			}
		}
	}
}

Good day.

You only need to this (I will not write the code, i will tell you what to use, look for how to use it correctly)

• Detect when user mantains button with Input.GetKey and instantiate the bullet as a child of your ship
• Then detect whn user relases the key with Input.GetKeyUp to unparent the bullet and start its movoment.

Bye!

Hi @Supermacka !

What I would do is Instantiating the object as a child of your shotPosition when spacebar is pressed. (make sure you only spawn it once)

When the player releases the spacebar remove the shot object’s parent and add force to it.

This would look something like this:

Rigidbody2D shot;
private void Shooting()
{
	if (Input.GetKey(KeyCode.Space) && charge < maxPower)
	{
		charge += Time.deltaTime * 30;
			
		if(shot == null)
		{
			shot = Instantiate(shotPrefab, shotPos) as Rigidbody2D;
		}
	}

	if (Input.GetKeyUp(KeyCode.Space) && canShoot == true && shot != null)
	{
		shot.transform.parent = null;

		shot.AddForce(shotPos.up * charge);

		shot = null;
		charge = defaultPower;
		canShoot = false;

	}
	else if (canShoot == false)
	{
		reloadTimer -= Time.deltaTime;

		if (reloadTimer <= 0)
		{
			reloadTimer = 1f;
			canShoot = true;
		}
	}
}

If this does not work for you please let me know.

Best,
