Error Shooting entity

Unity Engine
1

I am trying to get the game to shoot a projectile from the player. it is under addets, recources and its called projectile. when klicking to shoot i get this error:
ArgumentException: The Object you want to instantiate is null.
UnityEngine.Object.CheckNullArgument (System.Object arg, System.String message) (at C:/buildslave/unity/build/Runtime/Export/UnityEngineObject.bindings.cs:353)
UnityEngine.Object.Instantiate[GameObject] (UnityEngine.GameObject original) (at C:/buildslave/unity/build/Runtime/Export/UnityEngineObject.bindings.cs:251)
launch.Update () (at Assets/launch.cs:17)

Here is my script

using System.Collections;
using UnityEngine;

public class launch : MonoBehaviour {

    GameObject prefab;

    // Use this for initialization
    void Start () {
        prefab = Resources.Load("projectile") as GameObject;
    }
   
    // Update is called once per frame
    void Update () {
    if (Input.GetMouseButtonDown(0))
        {
            GameObject projectile = Instantiate(prefab) as GameObject;
            projectile.transform.position = transform.position + Camera.main.transform.forward * 2;
            Rigidbody rb = projectile.GetComponent<Rigidbody>();
            rb.velocity = Camera.main.transform.forward * 40f;
        }
    }
}

Make sure the folder is “Resources” and that “projectile” is spelled and capitalized correctly to match the asset.

It is,

3484573--277271--recouses.jpg

4

oh wait
it is re___C___ources

5

now it sais Assets/launch.cs(10,18): error CS0103: The name `Recources’ does not exist in the current context

6

I was talking about the folder.

That new error is because you misspelled “Resources”.

7

yes and i re

The folder is called recources, in my script it now also sais recources and now the error is Assets/launch.cs(10,18): error CS0103: The name `Recources’ does not exist in the current context

Sorry, no … that is backwards. You must name the folder “Resources” and change the code to that, too. :slight_smile:

Thank you, it works. could you help me with 1 more thing?

I have a script for movement and mousecontroll, but the mouse movement on the y axis doesnt work, but iit doesnt give any errors. Could you take a look?
My script is:

using System.Collections;
using UnityEngine;

public class FPSController : MonoBehaviour {

    CharacterController player;

    public float speed = 4f;
    public float sensitivity = 4f;

    float moveFB;
    float moveLR;

    float rotX;
    float rotY;
}

    // Use this for initialization
    void Start () {

        Cursor.lockState = CursorLockMode.Locked;
        player = GetComponent<CharacterController>();

    }
  
    // Update is called once per frame
    void Update () {

        moveFB = Input.GetAxisRaw("Vertical") * speed;
        moveLR = Input.GetAxisRaw("Horizontal") * speed;

        rotX = Input.GetAxis("Mouse X") * sensitivity;
        RotY = Input.GetAxis("Mouse Y") * sensitivity;

        Vector3 movement = new Vector3(moveLR, 0, moveFB);
        transform.Rotate(0, rotX, 0);

        movement = transform.rotation * movement;
        player.Move(motion: movement * Time.deltaTime);

        if (Input.GetKeyDown("escape"))
            Cursor.lockState = CursorLockMode.None;

    }
}

you’re not actually using RotY once it’s set…

11

How do i fix it than

12

Do you mean the rotation on the Y axis isn’t doing anything?

I copied and pasted your code. You had 2 errors, line #s : 16 and 33. Delete line #16 = ’ }’ and line 33 should be rotY =
I tried your code and it’s working well.

As noted, you weren’t actually using rotY, but other than that it was working :wink:

i changed and now it says Assets/FPSController.cs(15,11): warning CS0414: The private field FPSController.rotY' is assigned but its value is never used Assets/FPSController.cs(15,11): warning CS0414: The private field FPSController.rotY’ is assigned but its value is never used
