| | I'm having serious trouble, getting things to comply. I haven't had any error messages or anything, but when I run the program, my screen hasen't changed since step 1. At first I didn't mind the color thing, but now I can't get my triangle to appear. I followed the code step by step and have revised everything but to no avail. Here's my code so far:
#region Using Statements

public Game1()
{
graphics = new GraphicsDeviceManager(this);
content = new ContentManager(Services);
}
protected override void Initialize()
{
base.Initialize();
SetUpXNADevice();

}
private void SetUpXNADevice()

device = graphics.GraphicsDevice;
graphics.PreferredBackBufferWidth = 500;

effect = new Effect(graphics.GraphicsDevice, compiledEffect.GetEffectCode(), CompilerOptions.None, null);
}
private void SetUpVertices()
{
vertices = new VertexPositionColor[3];
vertices[0].Position = new Vector3(-0.5f, -0.5f, 0f);
vertices[0].Color = Color.Red;
vertices[1].Position = new Vector3(0, 0.5f, 0f);
vertices[1].Color = Color.Green;
vertices[2].Position = new Vector3(0.5f, -0.5f, 0f);
vertices[2].Color = Color.Yellow;
}
protected override void LoadGraphicsContent(bool loadAllContent)
{
if (loadAllContent)
{
}
}
protected override void UnloadGraphicsContent(bool unloadAllContent)
{
if (unloadAllContent)
{
content.Unload();
}
}
protected override void Update(GameTime gameTime)
{
device.Clear(Color.DarkSlateBlue);
effect.CurrentTechnique = effect.Techniques["Pretransformed"];
effect.Begin();
foreach (EffectPass pass in effect.CurrentTechnique.Passes)
{
pass.Begin();
device.VertexDeclaration = new VertexDeclaration(device, VertexPositionColor.VertexElements);
device.DrawUserPrimitives(PrimitiveType.TriangleList, vertices, 0, 1);
pass.End();
}
effect.End();
if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
this.Exit();
base.Update(gameTime);
}
protected override void Draw(GameTime gameTime)
{
graphics.GraphicsDevice.Clear(Color.CornflowerBlue);
base.Draw(gameTime);
}
}
}
Please help. Thanks for the toturials though :) | |
