here we go - MATH

Looks like moving my ball requires some cool math

moving to different points at a certain degree
moving from point 100,100 to 500,700 requires a slope of 53.13 Degree
i want to move a object from 100,100 to 500, 700
using the slope
and showing this object moving along this direction in a timer
anyone can help greatly appreciated

The equation of the line that goes through (100, 100) and (500, 700) is:

          700 - 100
y - 100 = --------- (x - 100)
          500 - 100

y - 100 = 600/400 * (x - 100)

y - 100 = 3/2 * x - 150

y = 3/2 * x - 50

So whenever we add one to x, we have to calculate y with 3/2 * x - 50.

Timer code:

picBall.Left = picBall.Left + 1
picBall.Top = picBall.Left * 3 / 2 - 50
If picBall.Left = 700 Then tmrBall.Enabled = False

Worth a shot!

still with that damn moving problem crap..

some how this doesnt want to move the img back to the original point it started moving from

here is the code if any one can see something i am not seeing please let me know, i changed orders of them like a million times, changed different subs..
still doesnt want to move backwards
grr

Option Explicit
Dim Slope As Double
Dim EndPoint As Integer
Dim x1, x2, y1, y2 As Integer

Private Sub imgOverDueMeters_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Call UpCordinates(3960, 2, 750, 2, 2)
End Sub

Private Sub imgPresentDueMeters_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Call DropCordinates(2, 3960, 2, 750, 3960)
End Sub

Private Sub tmrBack_Timer()
imgBall.Left = imgBall.Left - 50
imgBall.Top = (imgBall.Left * (y1 - y2) / (x1 - x2) + ((((y1 - y2) / (x1 - x2)) * (x1)) - y1))
If imgBall.Left <= EndPoint Then tmrBack.Enabled = False
End Sub

Private Sub TmrDrop_Timer()

imgBall.Left = imgBall.Left + 50
imgBall.Top = (imgBall.Left * (y2 - y1) / (x2 - x1) - ((((y2 - y1) / (x2 - x1)) * (x1)) - y1))
If imgBall.Left >= EndPoint Then TmrDrop.Enabled = False

End Sub
Private Sub SetCordinates(Xp1 As Integer, Xp2 As Integer, Yp1 As Integer, Yp2 As Integer, endP As Integer)
    x1 = Xp1
    x2 = Xp2
    y1 = Yp1
    y2 = Yp2
    EndPoint = endP
End Sub

Private Sub DropCordinates(x1 As Integer, x2 As Integer, y1 As Integer, y2 As Integer, endP As Integer)
If imgBall.Left >= endP Then
    Exit Sub
Else
    Call SetCordinates(x1, x2, y1, y2, x2)
    TmrDrop.Enabled = True
End If
End Sub
Private Sub UpCordinates(x1 As Integer, x2 As Integer, y1 As Integer, y2 As Integer, endP As Integer)
If imgBall.Left <= endP Then
    Exit Sub
Else
    Call SetCordinates(x2, x1, y2, y1, x1)
    TmrDrop.Enabled = True
End If
End Sub

Um, I'm not sure, but I think it has to do with the fact that you never enabled the tmrBack timer.
