Hi all. Forgive me if what you see below isn't up to par. I am new to this graphics programming stuff, so if you have any recommendations on the coding, or for that matter a simpler way of doing something, please critique. The reason I am posting this is because I need help making my character kenny jump. I thought about assigning the jump key to a timer, however when I put it in the timer event, it said I was unable to use the "keys.space" under the timer event because it says it is not part of "System.EventArgs" I am essentially going to try and create a pitfall game using kenny from southpark and various characters. Now currently I just have the form background as the background that will change when he reaches the right of the screen. I am going to have it rotate through screens eventually. Currently the ground is just part of the background. But as in pitfall I am going to want him to be able to drop to a lower level. If any of you have any ideas on how I will be able to have him drop to a lower level at times please let me know. I am using VB 2005 .net just so you know. Thanks for the help! Also, if you have any recommended books for .net game programming, please feel free to post the titles. Xtreme **CODE** Public Class Form1 Dim pos As Point Dim loc As String Dim dir As String Dim frame As Integer Dim formBack As Boolean Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown If pos.X < 485 Then Select Case formBack Case False Me.BackgroundImage = Image.FromFile("background/winter1.gif") Case True Me.BackgroundImage = Image.FromFile("background/winter2.gif") End Select If pos.X >= 485 Then pos.X = 5 End If '******************** 'Key Movement '******************** 'change direction graphic to left If e.KeyCode = Keys.Left Then pos.X -= 5 dir = "left" End If 'change direction graphic to right If e.KeyCode = Keys.Right Then pos.X += 5 dir = "right" End If frame += 1 If frame = 4 Then frame = 1 loc = "kenny/" & dir & frame & ".gif" Me.Invalidate() 'change to a crouch If e.KeyCode = Keys.Down Then loc = "kenny/rightCrouch1.gif" Me.Invalidate() End If ElseIf pos.X >= 485 Then pos.X = 5 formBack = Not (formBack) End If End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Setstyle(Controlstyles.DoubleBuffer, True) Setstyle(Controlstyles.AllPaintingInWmPaint, True) 'set default graphic and position loc = "kenny/right1.gif" pos.X = 5 pos.Y = 145 End Sub Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint Dim Bmp As New Bitmap(loc) Bmp.MakeTransparent(Color.Lime) e.Graphics.DrawImage(New Bitmap(Bmp), pos) End Sub End Class

Yes you are correct. How would I go about making him jump though? Been having a heck of a time trying to find code that works in .net to do so. I also am aware that it is probably due to my little knowlegde on the subject.

Hey,
There is an article in the resources section of this site in the math/physics area I believe with an excellent article on jumping. check it out.
Hope this helps.
