Game move function

[jammas615]

Hi, i a moveUp() and moveDown() function that currently just increment and decrement the "y" value each time they are called. The outcome of this is that my object only moves slowly, how could i add more than one, say 10, to the "y" value each time?
Those two functions look like this:

public moveUp() {
    y++;
}

public moveDown() {
    y++;
}

[yellowledbet]

y += 10;

or

y = y + 10;
