Problems in the execution of the shot

Hello.
I have a problem when shooting: I am doing types of shots (like a shotgun and similar) but two do not work for me:

Burst Shot: What it does is it creates all the bullets at the same time, making the bullets not separated.

else if(tipoDisparo_SD == "2A")
                {
                    if(cadencia_SD <= 0)
                    {
                        int i = requisito_SD;
                        while(i != 0){
                            DispararRafaga();
                            cadencia_SD = 0;
                            i--;
                        }

                        cadencia_SD = CADENCIA;
                    }
                    else
                    {
                        cadencia_SD -= Time.deltaTime;
                    }
                }

private void DispararRafaga(){

        Instantiate(bala_SD[0], pos.position, pos.rotation);
        QuitarBalas(requisito_SD);
        Debug.Log("Dispara");
    }

Bullet hell shot: creates all the bullets but fires them in the same position ignoring what is shown in the debug.log. In this it shows that it does the operation correctly.

case "4A":
                div = 360 / requisito_SD;
                rotacion = jugadorGirador.rotation;
                res = div;
                Debug.Log("Grados: " + res);

                for(int i = 1; i <= requisito_SD; i++){
                    rotacion.z += res;
                    Instantiate(bala_SD[0], pos.position, rotacion);
                    Debug.Log("Rotacion: " + rotacion.z + " de: " + i);
                    Debug.Log("ROT: " + rotacion);
                }
                break;

What will be the problem?

Hi Raxwe, thanks for the info. I am not sure I understand fully. I wonder are you able to provide some image or video on the issue you are facing?

In the image you can see 5 arrows, which is where the 5 bullets are supposed to go in that direction. But all 5 bullets come out the same side (orange dots). You can also see that the 5 bullets are created correctly. there is also a Debug.log that shows that it seems to do the correct operation. But the execution is wrong.

This is NOT what you think it is. It has absolutely NOTHING to do with degrees. This is an internal component of Quaternions, which have internal x, y, z, and w components.

Do NOT touch ANY of those components unless you have a math degree and know what you’re doing.

Instead, either use the Quaternion.Euler() factory method to make each of your rotations, or else use a pre-made constant one (such as Quaternion.Euler(0,0,res)) and multiply the rotacion variable by it each time to make it “spread”

I am close to achieving it, but there is a bullet that does not come out correctly, and the appearance of the bullets is fixed, I show you the script:

case "4A":
                div = 360 / requisito_SD;
                rotacion = jugadorGirador.rotation;
                res = div;
                Debug.Log("Grados: " + res);

                for(int i = 1; i <= requisito_SD; i++){
                    res += res;
                    rotacion = Quaternion.Euler(0, 0, res);
                    Instantiate(bala_SD[0], pos.position, rotacion);
                    Debug.Log("Rot: " + rotacion.z + " de " + i);
                }
                break;

To combine I only need to multiply them… But there is still a bullet that is not created where it is… (I think it is when it is 0)

case "4A":
                div = 360 / requisito_SD;
                rotacion = jugadorGirador.rotation;
                res = div;
                Debug.Log("Grados: " + res);

                for(int i = 1; i <= requisito_SD; i++){
                    res += res;
                    var rot = Quaternion.Euler(0, 0, res);
                    rotacion = rotacion * rot;
                    Instantiate(bala_SD[0], pos.position, rotacion);
                    Debug.Log("Rot: " + rotacion.z + " de " + i);
                }
                break;

One build fails when ‘requisito_SD = 5’ but setting ‘requisito_SD = 9’ fails three. What can I do?

This doesn’t seem right. It is the equivalent of res *= 2;

Do you mean res += div; perhaps?

Again, you should remove this:

rotacion.z is meaningless. Stop letting it confuse you.

8

I fixed it. Line 9 is left over. Since I added the multiplication, I was “adding” more times than I should have.

case "4A":
                div = 360 / requisito_SD;
                rotacion = jugadorGirador.rotation;
                res = div;
                Debug.Log("Grados: " + res);

                for(int i = 1; i <= requisito_SD; i++)
                {
                    // res += res; -> needless
                    var rot = Quaternion.Euler(0, 0, res);
                    rotacion = rotacion * rot;
                    Instantiate(bala_SD[0], pos.position, rotacion);
                    Debug.Log("Rot: " + rotacion.z + " de " + i);
                }
                QuitarBalas(requisito_SD);
                break;

Now it is necessary to improve the burst style shot (create all the bullets at the same time without separation)

case "2A":

                for(int i = 1; i <= requisito_SD; i++)
                {
                    Invoke("DispararRafaga", 2f);
                }

private void DispararRafaga(){

        Instantiate(bala_SD[0], pos.position, pos.rotation);
        QuitarBalas(requisito_SD);
        Debug.Log("Dispara");
    }

Hi Raxwe, great that you have found the solution. :slight_smile:

10

When shooting in burst mode no. the others are functional

11

Hi Raxwe, do you have a image or video sample that you would like to achieve in your burst mode?

12

Hi Raxwe, same here you need to pass in the Quaternion.Euler() to into your Instantiate(gameObject, position, Quaternion)

var angle = 40 // example 40 degree angle
var rotation = Quaternion.Euler(0, 0, angle);
Instantiate(bala_SD[0], pos.position, rotation);
