Snowball shotgun Math problems

I'm trying to experiment with guns a little bit and wanted to make a shotgun, i'm having trouble with trying to dispearse the snowballs in the beginning. this is what i have atm:

Code:

for(int i = 0; i < 24; i++){
Snowball snowball = p.launchProjectile(Snowball.class);
float x = (float) -0.5 + (float) (Math.random() * ((0.4 - -0.4) + 0.3));
float y = (float) -1.0 + (float) (Math.random() * ((0.8 - -0.5) + 0.4));
float z = (float) -0.5 + (float) (Math.random() * ((0.4 - -0.3) + 0.3));
Vector dir = p.getLocation().getDirection();
snowball.setVelocity(dir.multiply(new Vector(snowball.getVelocity().getX()+x, snowball.getVelocity().getY()+y, snowball.getVelocity().getZ()+z)).normalize());
}

 

Still need help with this so bumping it

 

So what's wrong?

 

they are basicly all in eachother and i want them spreaded out, like a shotgun should do.

 

Try removing the multiply and just using the vector.

 

So basicly like this?

Code:

[FONT=Consolas]for(int i = 0; i < 24; i++){
Snowball snowball = p.launchProjectile(Snowball.class);

Vector dir = p.getLocation().getDirection();
snowball.setVelocity(dir.multiply().normalize());
}[/FONT]

If so, that wouldn't really work because it does the same thing with the vector (but worse), they are all inside 1 line.

 

frogawesome What's with the - - in your math?

 

No, now you're just not applying anything to the snowballs. You have to make the modifications to the x/y/z values of the original vector and then fire it, whether it be via .add() or via creating a new vector.

 

Ahh, now I get it, I'll try that tomorrow
