Shooting script help.

Unity Engine
1

hey, I am not a programmer of any kind, which is why I need help with such a simple script.

I need to change the GetButtonDown input to the enter key. (I dont remember how to do this.)
And i would also like to change the direction of the bullets to where the character is facing.

Thanks.

var prefabBullet:Transform;
var shootForce:float;

function Update()
{
    if(Input.GetKeyDown(KeyCode.Return))
    {
        var instanceBullet = Instantiate(prefabBullet, transform.position, Quaternion.identity);
        instanceBullet.rigidbody.AddForce(transform.TransformDirection(transform.forward * shootForce));
    }
}

The bullets are going in the direction the character is facing (unless your model is incorrectly made). Can you explain what is happening?

I don’t usually AddForce to start a projectile. In the example for Instantiate they use:

instanceBullet.velocity = transform.TransformDirection(Vector3.forward * shootForce);  // Adapted to fit your code

Actually my character doesn’t rotate. only goes from left to right. I bought the 2D sidescroller pack from Unityprefabs.com. I regret it now, because it would have been easier to do on my own.

Btw, thanks for the script.

@Dman
Would you mind taking a look at my project, and making my character rotate when it moves. (as in turn the direction it is going.)
Its a 2d side scroller so probably wouldn’t be to hard.

I believe they go over that in the 2d platformer tutorial if you wish to do that yourself.
http://unity3d.com/support/resources/tutorials/2d-gameplay-tutorial.html

Otherwise I can take a look later, but I cannot guarantee that I will finish it in a reasonable timeframe.

Hi I’m too I’m working on a 2d platform game, its fully done almost, you can rotate and look up and down.

Add me and I can screen share to show you how it works and send it to you just remember to say in skype that you meet new because of the forums so I remember that you are the one that needs help and don’t worry I’m not here for money but to help you out.
