首先我们要做一些前置操作 SDL: 开放源代码的跨平台多媒体开发库 Premake量跨平台构建系统
环境: VS 2019以及完整的C编译环境
Rider For Unreal Engine 2022.2.1下面简称Rider
Unity 2019.4.8 lts
.Net Core 2.2
1.首先把git库拉到本地先将下载的SDL库放到ecastnavigation\RecastDemo\Contrib,需要改名为SDL应该得到如下目录recastnavigation-master\RecastDemo\Contrib\SDL\lib\x64 2/然后将下载premake5.exe放入 recastnavigation\RecastDemo 3.然后通过命令行控制premake编译recastnavigation为sln工程
PS E:\recastnavigation\RecastDemo .\premake5.exe vs2019

Done (160ms).然后目录中会生成一个Build文件夹里面是我们编译出来的sln工程
recastnavigation\RecastDemo\Build\vs2019\recastnavigation.sln用rider打开直接运行我们就能看到编辑器画面了
接下去我们要对源码进行一些改造 原始的recast是没有开始点和结束点的坐标的那如何能显示出来呢
void NavMeshTesterTool::handleRenderOverlay(double* proj, double* model, int* view)
{GLdouble x, y, z;char buf[64];// Draw start and end point labelsif (m_sposSet gluProject((GLdouble)m_spos[0], (GLdouble)m_spos[1], (GLdouble)m_spos[2],model, proj, view, x, y, z)){if (m_showCoord){snprintf(buf, sizeof(buf), Start (%.1f, %.1f, %.1f), m_spos[0], m_spos[1], m_spos[2]);imguiDrawText((int)x, (int)(y - 25), IMGUI_ALIGN_CENTER, buf, imguiRGBA(0, 0, 0, 220));}elseimguiDrawText((int)x, (int)(y - 25), IMGUI_ALIGN_CENTER, Start, imguiRGBA(0, 0, 0, 220));}if (m_toolMode TOOLMODE_RAYCAST m_hitResult m_showCoord gluProject((GLdouble)m_hitPos[0], (GLdouble)m_hitPos[1], (GLdouble)m_hitPos[2],model, proj, view, x, y, z)){snprintf(buf, sizeof(buf), HitPos (%.1f, %.1f, %.1f), m_hitPos[0], m_hitPos[1], m_hitPos[2]);imguiDrawText((int)x, (int)(y - 25), IMGUI_ALIGN_CENTER, buf, imguiRGBA(0, 0, 0, 220));}if (m_eposSet gluProject((GLdouble)m_epos[0], (GLdouble)m_epos[1], (GLdouble)m_epos[2],model, proj, view, x, y, z)){if (m_showCoord){float totalCost 0.0f;for (int i 0; i 1 m_nstraightPath; i)totalCost dtVdist(m_straightPath[i * 3], m_straightPath[(i 1) * 3]);snprintf(buf, sizeof(buf), End (%.1f, %.1f, %.1f), Cost %.1f, m_epos[0], m_epos[1], m_epos[2], totalCost);imguiDrawText((int)x, (int)(y - 25), IMGUI_ALIGN_CENTER, buf, imguiRGBA(0, 0, 0, 220));}elseimguiDrawText((int)x, (int)(y - 25), IMGUI_ALIGN_CENTER, End, imguiRGBA(0, 0, 0, 220));}
}那么如何能显示出关键点point list?首先路径搜索的模式要改成TOOLMODE_PATHFIND_STRAIGHT模式代码需要增加如下的打印 在NavMeshTesterTool.cpp中增加
void NavMeshTesterTool::recalc(){
....
....if (m_toolMode TOOLMODE_PATHFIND_STRAIGHT m_nstraightPath0) {stringstream os;os total point size m_nstraightPath ,;//m_sample-getContext()-log(RC_LOG_PROGRESS, total point size%d, m_nstraightPath);for (int i 0; i m_nstraightPath; i){if (i 0i%100) {m_sample-getContext()-log(RC_LOG_PROGRESS, %s, os.str().c_str());os.str();}os [ m_straightPath[i * 3] , m_straightPath[i * 3 1] , m_straightPath[i * 3 2] ] ;}m_sample-getContext()-log(RC_LOG_PROGRESS, %s, os.str().c_str());}
}在Sample.h中增加
public:Sample();virtual ~Sample();void setContext(BuildContext* ctx) { m_ctx ctx; }BuildContext* getContext() {return m_ctx;}最后一个问题如何把显示日志的地方的文本能鼠标选中目前还没搞定
