Lesson 32: Creating Animation using Timer in VB6

Learn to create automatic animations using Timer control for smooth, continuous motion effects

Key Takeaway

VB6 Timer control enables creating automatic animations by triggering events at regular intervals, allowing for smooth and continuous motion effects.

Welcome to Lesson 32 of our Visual Basic 6 Tutorial! In this lesson, you'll learn how to create automatic animations using the Timer control, which allows you to create smooth and continuous motion effects without manual interaction.

32.1 Animation using Timer Control

All preceding examples of animation you've learned required manual interaction (clicking buttons or pressing keys). To create automatic animations, you need to use the Timer control. The Timer triggers events at regular intervals, allowing you to update your animation frames automatically.

1Timer Setup

Drag a Timer control from the toolbox onto your form and set its Interval property

2Interval Value

Set interval in milliseconds (1000ms = 1 second). Lower values create faster animations

3Timer Event

Write your animation code in the Timer's Timer event to execute at each interval

Simple Two-Frame Animation

This example shows a dinosaur and a dog alternating automatically using a Timer:

Dog and Dino Animation
Figure 32.1: Automatic Dog/Dino Animation
TimerAnimation.frm
Private Sub Timer1_Timer()
    If Image1.Visible = True Then
        Image1.Visible = False
        Image2.Visible = True
    ElseIf Image2.Visible = True Then
        Image2.Visible = False
        Image1.Visible = True
    End If
End Sub
                        

Explanation

The Timer event alternates between two images by toggling their Visible property. The Timer's Interval property determines how frequently this toggle happens.

Complete Motion Animation

For more complex animations like a butterfly flapping its wings, use a Timer to cycle through multiple frames:

Butterfly Animation
Figure 32.2: Automatic Butterfly Animation
ButterflyAnimation.frm
Private Sub Form_Load()
    Image1.Visible = True
    Timer1.Enabled = False ' Disabled until button click
End Sub

Private Sub Command1_Click()
    Timer1.Enabled = True ' Start animation
End Sub

Private Sub Timer1_Timer()
    If Image1.Visible = True Then
        Image1.Visible = False
        Image2.Visible = True
    ElseIf Image2.Visible = True Then
        Image2.Visible = False
        Image3.Visible = True
    '... (other frames similarly)
    ElseIf Image8.Visible = True Then
        Image8.Visible = False
        Image1.Visible = True
    End If
End Sub
                        

Timer Animation Demo

This demo simulates the Timer control in action. Adjust the interval to control animation speed:

100 ms
Frame 1

Important Note

For smoother animations, use a Timer with a low interval value (50-100ms) and ensure all frames are preloaded and positioned correctly.

Lesson Summary

In this lesson, you've learned how to create automatic animations in VB6 using the Timer control:

Timer Fundamentals

Use the Timer control to trigger events at regular intervals

Interval Control

Adjust the Interval property to control animation speed

Frame Cycling

Cycle through multiple frames in the Timer event for complex animations

Start/Stop Control

Enable/disable the Timer to start and stop animations programmatically

Pro Tip

For even smoother animations, consider using the Windows API for high-resolution timing, especially for games or complex animations.
