使用游戏引擎实现的水波纹
这是波纹的截图。 程序运行时是波动的。
代码如下:
public static void valfff()
{
int ScreenWidth = 800; //; Feel free to change this to see the pixel filling speed !
int ScreenHeight = 600;
int[] CosTable = new int[ScreenWidth * 2];
int[] ColorTable = new int[255];
for (int i = 0; i {
CosTable[i] = (int)(GSin(360 * i / 320) * 32 + 32);
}
GameScreen gs = new GameScreen();
// gs.OpenWindowedScreen(hande, 0, 0, 800, 600, 0, 0, 0);
gs.OpenFullScreen(ScreenResolution.R800X600, ScreenColorDepth.X32, "srlPlasma");
int Wave = 0;
do
{
int tc = GetTickCount();
Wave += 6;
Wave = (Wave > 320) ? Wave = 0 : Wave;
Console.Write(Wave);
if (gs.StartDrawing() != 0)
{
int iBuffer = gs.DrawingBuffer();
int iPitch = gs.DrawingBufferPitch();
PixelFormat iPixelFormat = gs.DrawingBufferPixelFormat();
if (iPixelFormat == PixelFormat.PF32Bits_RGB)
{
for (int i = 0; i {
ColorTable[i] = i }
}
else
{
for (int i = 0; i {
ColorTable[i] = i;
}
}
for (int y = 0; y {
int pos1 = CosTable[y + Wave];
int loc = iBuffer + iPitch * y;
for (int x = 0; x {
int pos2 = (CosTable[x + Wave] + CosTable[x + y] + pos1);
gs.SetVideoMemory(loc, ColorTable[pos2]);
loc += 4;
}
}
gs.StopDrawing();
}
gs.FlipBuffers();
Console.WriteLine(GetTickCount() - tc);
} while (gs.KeyIsReleased(Key.Escape) == false);
gs.Close();
}
public static float GSin(float angle)
{
return (float)Math.Sin(angle * (2 * 3.14 / 360));
}
