Fixing the Timer1 Glitch - Moving a Picture Box on a Screen

[Marghk]

Just have to get a picture box to move around a screen, I'm running the program by a timer. I'll show set integers below.

Timer = Timer1
Picture Box = Robot
Dim Robotpace as integer


Basically, when you click on the start button it enables the timer. Here's the coding.



Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

RobotPace = 8
Robot.Left -= RobotPace
If Robot.Left <= 1 Then
Robot.Left = False
Robot.Top -= RobotPace
If Robot.Top <= 1 Then
Robot.Top = False
+ Robot.Left += RobotPace
+ If Robot.Left <= 1 Then
+ Robot.Left = False


End If
End If

End Sub



The lines with the (+'s) at the start of them are the beginning of the error. At this point, I'm aware that the timer mistakes the + and - statements in the Robot.Left movements and it completely glitches.

I just can't fix this.

Hi there,

From what I can see, it looks like the issue might be with the placement of your If statements. You have an If statement nested within another If statement, and it may be causing the code to not execute properly. I would suggest rearranging the code so that the If statements are not nested, and also adding an Else statement to handle the case when the Robot.Left is not <= 1.

Also, it might be helpful to add some comments to your code to make it more clear what each section is doing. For example, you could add a comment above the line "RobotPace = 8" saying something like "Set the pace of the robot's movement" to help make your code more organized and easier to understand.

I hope this helps, and good luck with your project!

It seems like the issue here is with the logic in your code. When the timer ticks, you are setting the RobotPace to 8, which means the picture box will move 8 pixels to the left every time the timer ticks. However, in your code, you are also checking for the picture box's position to be less than or equal to 1, which would mean it has moved off the screen. This could be causing your glitch.

Instead, you could try setting a different condition for when the picture box should stop moving. For example, you could use the width and height of the form to determine when the picture box should stop moving, rather than a specific pixel value.

Also, it looks like you are trying to move the picture box diagonally, but your code is currently only moving it horizontally and vertically. You may need to add additional conditions and logic to achieve diagonal movement.

Overall, it's important to carefully plan and test your code, and make sure your logic is sound before implementing it. I suggest breaking down the problem into smaller steps and tackling them one at a time, rather than trying to fix the entire code at once. This will also make it easier to troubleshoot any issues that arise.

I hope this helps and good luck with your project!
