Question

At the moment I have this code which fires a projectile:

Vector3 d = mousePos.sub(pouchPos.x, pouchPos.y, 0);
        d.mul(FIRE_SPEED);
        projectile.setVelocity(-d.x, -d.y);

Which works fine, and this which sets the position according to the mouse position:

turtle.body.setTransform(mousePos.x, mousePos.y, 0);

        if (turtle.pos.dst(pouchPos) > 5)
        {
            //What to put in here?
        }

Trouble is I don’t know what to put in the if (turtle.pos.dst(pouchPos) > 5) clause. What would you suggest?

Answer 1

if ( length > limit ) 
    vector.mul( limit / length );
