I cant figure out why this isnt animating >=/

Code:

---

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace _D_game_01
{
    public partial class GForm : Form
    {
        Point BallLocation = new Point(10, 10);
        Size BallSize = new Size();
        Point LinePoint1 = new Point();
        Point LinePoint2 = new Point();
        int[] buffer = new int[1] { 0 };

        public GForm()
        {
            InitializeComponent();
        }

        private void GPanel_Paint(object sender, PaintEventArgs e)
        {
            Graphics G = e.Graphics;

            G.Clear(Color.CornflowerBlue);

            SetupLines(sender, e);
            SetupBall(sender, e);

            this.Invalidate();
        }

        private void SetupLines(object sender, PaintEventArgs e)
        {
            try
            {
                e.Graphics.DrawLine(Pens.Black, LinePoint1 = new Point(0, e.ClipRectangle.Height / 6 * 5), LinePoint2 = new Point(e.ClipRectangle.Width, e.ClipRectangle.Height / 6 * 5));
            }
            catch { }
        }

        private void SetupBall(object sender, PaintEventArgs e)
        {
            try
            {
                e.Graphics.DrawArc(Pens.Black, new Rectangle(BallLocation, BallSize = new Size(e.ClipRectangle.Height / 10, e.ClipRectangle.Height / 10)), 0, 360);
            }
            catch { }
        }

        private void Tmr_Update_Tick(object sender, EventArgs e)
        {
            try
            {
                BallLocation.Y += buffer[0];

                if (BallLocation.Y < LinePoint1.Y - BallSize.Height)
                    buffer[0] += 1;

                if (BallLocation.Y >= LinePoint1.Y - BallSize.Height)
                    buffer[0] = 0;

                if (BallLocation.Y > LinePoint1.Y - BallSize.Height)
                    BallLocation.Y = LinePoint1.Y - BallSize.Height;
            }
            catch { }
        }

        protected override void OnKeyPress(KeyPressEventArgs e)
        {
            if (e.KeyChar == (byte)Keys.Escape)
                this.Close();
        }
    }
}

Thanks in advance!

where are you creating your timer?

I created the timer in the designer. It's enabled with an interval of 10.

Seems the timer isnt working at all =/
If all my code in the timer tick is

Code:

---

this.Text += "a";

---

The window title doesnt change at all.

Whats wrong with the timer? =O

Hi

Check, Whether time is enable or not,

Check after loading the form or at the time of loading form

That is because of this line of code:

Code:

---

this.Invalidate();

---

in your paint handler. Please try to debug your program and see what happens. In addition I think you have some bugs in your timer function. Review the whole program.

The bugs in the timer function doesnt matter :) It's not even started yet. I will keep that going after i've gotten the timer to work.
I removed Invalidate(), but it still isnt moving

OK, i moved this.Invalidate() from the paint onverride to the Timer tick :)

Working =D

Thanks!
