Re: Making a moving instance of an object in scratch

More fully:

When I receive [shoot] {
    Go to [tank]
    Change x by (amount)
    Change y by (amount)
    Point in direction (direction of tank)
    Show
    Repeat until <touching edge> {
        Move (10) steps
    }
    Hide
}

The change x/y part is to make sure the bullet appears to come out of the tank's barrel; tweak as necessary. The Repeat could be a set number, instead of until touching the edge; that would control the shot's distance. The 10 in the Move (10) steps will be the speed of the bullet.
