Question

Would it be possible to have something like this: http://newgrounds.com/portal/view/417593 where the projectiles are shot at a set time interval (for example: every half second) at a set velocity without the need for mouse input?

Absolutely! Take a look at InvokeRepeating. You can use it to repeatedly call the specified function at a given interval.

The function that you call could spawn the projectile with a default velocity.

The script you've posted in the comments seems to be a bit of frankencode, but from it I think I can see what you're trying to do with it.

I think this is closer to what you want:

var projectile : Rigidbody;
var projectileSpeed : float = 10;

function Start ()
{
   InvokeRepeating("LaunchProjectile", 2, 0.3);
}

function LaunchProjectile ()
{
   var instance : Rigidbody = Instantiate(projectile, transform.position, transform.rotation);
   instance.velocity = transform.forward * projectileSpeed; // usually use AddForce
   Physics.IgnoreCollision( instance.collider, transform.root.collider );
}

If you don't understand any particular part, check out the Scripting Reference or comment back!

Thank you. When I tried that script and selected a projectile, after that projectile was shot, the next one would be shot originating from the first projectile, and then the third projectile was shot from the second, etc. How can I make it so that it always shoots from the player (I added the script to the player object)?

If the script is on the player object, use 'transform.position' to get the current position of the player. If you're having troubles, update your question with your code and I can give you a more specific answer!

// Starting in 2 seconds. // a projectile will be launched every 0.3 seconds

var projectile : Rigidbody;

InvokeRepeating("LaunchProjectile", 2, 0.3);

function LaunchProjectile () { var instance : Rigidbody = Instantiate(projectile); instance.velocity = transform.position; transform.rotation ; instantiatedProjectile.velocity = transform.TransformDirection( Vector3( 0, 0, speed ) ); Physics.IgnoreCollision( instantiatedProjectile. collider, transform.root.collider ); }

This script is the one you linked me to spliced with another script that fires when I click down.

I think you're missing some of your code. 'transform.rotation' isn't being set, and theirs no definition for 'instantiatedProjectile'.

I've updated my answer with some example code based on yours.

Timed events (that repeat)?
