Unity游戏开发实战：用Flow Field实现RTS百人军团流畅寻路（附完整代码）本文深入探讨了在Unity中利用流场寻路技术解决RTS游戏大规模单位移动性能瓶颈的实战方案。通过解析从Dijkstra算法生成成本场、积分场到最终向量场的核心原理，并结合分块、缓存及与DOTS/ECS架构集成的优化策略，实现了百人军团的流畅群体寻路。文章提供了完整的代码示例，助力开发者构建高性能的RTS寻路系统。阅读详情

本人用BCB6用SDK建立了一個WIN32程序，為什麼程序一運行就退出了？
工程的建立方式為file-new-other，選擇控制台應用程序，在向導中，沒有選中Use VCL, Use CLX, Multi threaded, Console Application
下面是源碼：

#include <windows.h>
#include <d3d9.h>

#pragma link "d3d9.lib"

const char *CLASS_NAME = "D3DExample1";
const char *WINDOW_NAME = "My first d3d application";

LPDIRECT3D9 g_lpD3D;
LPDIRECT3DDEVICE9 g_lpD3DDevice;

HRESULT CALLBACK WndProc(HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam)
{
switch (nMsg)
{
case WM_DESTROY:
{
PostQuitMessage(0);
return 0;
}
}

return DefWindowProc(hWnd, nMsg, wParam, lParam);
}

INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wndCls;

wndCls.lpszMenuName = NULL;
wndCls.lpszClassName = NULL;

if (!RegisterClassEx(&wndCls))
return -1;
