Car Timer

Question

Trying to find away to get my car image to slow down from an initial fast speed before stopping using this timer. Can someone offer some help please I don't no how to link my image to these calculations

private int speedCounter = 100; //Speed for this many intervals
private void timer1_Tick(object sender, EventArgs e)
{

         if (speedCounter > 0)
              {
   --speedCounter;
         if (timer1.Interval < 600)
              {
                timer1.Interval++;
                }
         else
               timer1.Enabled = false;
            }
}

It would be better if you uploaded the source as a file. -As then i would be able to test and see the problem myself

Thanks for the reply. I 'll show what I'm working with with maybe that will make it a bit clearer. I think it may be my delaycount at the start which is causing the problem, what do you think? using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; namespace Move { public partial class Move : Form { public Move() { InitializeComponent(); } static void Main() { Application .Run( new Move ()); } double carBrake; double roadCon; double combWeight; double thinkDis; double thinkTime; double vehSpeed; double brakDis; double brakeTime; double stopTime; double stopDist; int position; double vehSpeedkmh; private void delayloop( int delayCount) // simple nested loop to delay processing //method called with paramater passed { for ( int i = 0; i // outer loop controlled by delayCount { for ( int j = 0; j // empty loop to act as delay } //loop i } //delay private void ThinkingTime_SelectedIndexChanged( object sender, EventArgs e) { switch (ThinkingTime.SelectedIndex) { case 0: thinkTime = ( float ) 0.25; break ; case 1: thinkTime = ( float ) 0.7; break ; case 2: thinkTime = ( float ) 1.25; break ; } // switch (ThinkingTime.SelectedIndex) } // ThinkingTime_SelectedIndexChanged private void cbImage_SelectedIndexChanged_1( object sender, EventArgs e) { switch (cbImage.SelectedIndex) { case 0: pbCar.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Racing.jpg" )); carBrake = ( float )2; break ; case 1: pbCar.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Rally.jpg" )); carBrake = ( float )1.6; break ; case 2: pbCar.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Performance.jpg" )); carBrake = ( float )1.3; break ; case 3: pbCar.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Normal.jpg" )); carBrake = ( float )1; break ; case 4: pbCar.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Worn Brakes.jpg" )); carBrake = ( float )0.7; break ; case 5: pbCar.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Poor tyres and brakes.jpg" )); carBrake = ( float )0.4; break ; } //switch (cbImage.SelectedIndex) } // cbImage_SelectedIndexChanged_1 private void cbRoadCondition_SelectedIndexChanged( object sender, EventArgs e) { switch (cbRoadCondition.SelectedIndex) { case 0: pbWeather.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Dry Road.jpg" )); roadCon = ( float ) 0.75; break ; case 1: pbWeather.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Dry Road.jpg" )); roadCon = ( float ) 0.6; break ; case 2: pbWeather.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Damp Road.jpg" )); roadCon = ( float ) 0.6; break ; case 3: pbWeather.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Damp Road.jpg" )); roadCon = ( float ) 0.45; break ; case 4: pbWeather.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Wet Road.jpg" )); roadCon = ( float ) 0.4; break ; case 5: pbWeather.Image = Image .FromFile( Path .Combine( Application .StartupPath, "Wet Road.jpg" )); roadCon = ( float ) 0.26; break ; } // switch (cbRoadCondition.SelectedIndex) } // cbRoadCondition_SelectedIndexChanged private void btnReset_Click_1( object sender, EventArgs e) { pbCar.Left = 0; // Reset Image back to start } private void sbSpeed_Scroll( object sender, ScrollEventArgs e) { lblSpeed.Text = "Speed in Km/h = " + sbSpeed.Value.ToString(); } // sbSpeed_Scroll private void btnMove_Click_1( object sender, EventArgs e) { // set delay from slider then move picture with delay time int delay = 4 * sbSpeed.Value; // Proportional delay for (position = 0; position { delayloop(delay); pbCar.Left = position; } // For Move // Calculations combWeight = carBrake * roadCon; thinkDis = vehSpeedkmh * thinkTime; vehSpeed = vehSpeedkmh * 1000 / 3600; brakDis = (vehSpeedkmh * vehSpeedkmh) / (2 * combWeight * 9.81); brakeTime = 2 * brakDis / vehSpeedkmh; stopTime = thinkTime + brakeTime; stopDist = brakDis + thinkDis; delay = sbSpeed.Maximum - sbSpeed.Value; // Output Results Results.Text = "Speed (Km/h) = " + vehSpeedkmh.ToString() + "

Hello, If your desire is to move an image using the PictureBox then all you need to do is: //At the end of the if statement add pictureBox1.Location = new Point(pictureBox1.Location.X + 1, pictureBox1.Location.Y); //This will increase the X position of the pictureBox by 1 each time the timer tick. //It won't look so natural as you might desire but it's what I believe you ask for
