This is the character that we will animate.

}
}
This might not be the best way to do it and i don't have any clues how to do it with a different way.At least it works for me. When i put a value in the currentFrame.Y it means that i want when i press that specific button it will go to that specific collumn of the sprite sheet. In this example i have 4 collumns and three frames for each collumn that referes to the Point sheetSize = new Point(3,4 );
When i have time i will comment it.
Hope it works for you too guys.
And a big Thanx to SixOfEleven for the GIMB tool suggestion now i can make transparent all my sprites.
