I'm posting my complete code here in the hopes that someone can tell me what I'm doing wrong to get HGE to run in a child window (hwndHGE in this case).
| Code: |
#define SCREEN_X 1024
#define SCREEN_Y 768
#include <windows.h>
#include <hge.h>
#include <hgeresource.h>
#include <string>
#include "resource.h"
using namespace std;
HGE* hge = 0;
hgeResourceManager* g_pRes = NULL;
LRESULT CALLBACK ToolProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);
LRESULT CALLBACK HGEProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);
// This function will be called by HGE once per frame.
bool FrameFunc()
{
// Continue execution
return false;
}
// This function will be called by HGE when
// the application window should be redrawn.
// Put your rendering code here.
bool RenderFunc()
{
// Begin rendering quads.
// This function must be called
// before any actual rendering.
hge->Gfx_BeginScene();
// Clear screen with black color
hge->Gfx_Clear(0);
// End rendering and update the screen
hge->Gfx_EndScene();
// RenderFunc should always return false
return false;
}
