how to stop the character to stop moving when hes walking on a tree.

the background is image1 jpg and the character is image2 and the tree is image3.

the code is:

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode = vbKeyUp Then Image2.Top = Image2.Top - 200
If KeyCode = vbKeyDown Then Image2.Top = Image2.Top + 200
If KeyCode = vbKeyLeft Then Image2.Move Image2.Left - 200
If KeyCode = vbKeyRight Then Image2.Move Image2.Left + 200


End Sub
