I didnt know what section to post this in soooo here goes.

I am having a issue with hans211 d3d based menu. with it shadows are actually rendered from the game menu itself.
Also if i turn on the ingame bloom affect the seccond screen shot shows what happens. Any idea why?






Here is the 2 parts of the source code that handle it

First is d3dmenu.cpp
Code:
//   Project : Basic D3D Menu v1.2
//   Author   : Hans211
//   Date   : 4 April 2008
//
//   Credits : Game-Deception for their info and support
//   
//   Tools used:
//      Microsoft Visual Studio c++ 6.0
//      DirectX9 SDK Update (summer 2004)
//      D3Dfont.cpp
//
//   Features:
//      Use Insert key to show/hide menu
//      Use up and down arrow keys to manouvre through the menuitems
//      Use left and right arrow keys to toggle menuitems
//      Items can have multiple custom states like: "Off" "On"  or "Head" "Neck" "Spine"
//      Support for textonly items
//      Support for folder style items
//
//  Changes:
//    1.2   Thx to DXT-Wieter20 for pointing this out
//         Check for left and right key first and then if value is within range
//
#include "d3dmenu.h"

char      Mtitle[81]="";     // Some room for a title
int       Mpos=0;           // current highlighted menuitem   
int       Mmax=0;           // number of menu items
int         Mxofs =160;     // offset for option text
int         Mysize=14;     // heigh of a menuline
int         Mvisible=1;

// predifine some basic options
char      *Moptfolder[] = { "+"  , "-" };   
char      *Moptonoff[]  = { "Off", "On"};
bool menulock = false;

    SetRect( &rect, x+Mxofs/2, y, x+Mxofs /2 , y );
  if (!Mvisible) return;

  if (Mtitle[0]) {

     pFont->DrawText(NULL,Mtitle,-1,&rect,DT_NOCLIP | DT_CENTER, MCOLOR_TITLE);

     y+=Mysize;
  }
  for (i=0; i<Mmax; i++) {
      val=(MENU[i].var)?(*MENU[i].var):0;
      // determine color
       if (i==Mpos)
           color=MCOLOR_CURRENT;
       else if (MENU[i].typ==MENUFOLDER)

      pFont->DrawText(NULL,MENU[i].txt,-1,&rect3, DT_NOCLIP,color);
       if (MENU[i].opt) {

      }
       y+=Mysize;
  }
}

void MenuNav(void)
{
  if (GetAsyncKeyState(VK_INSERT)&1) Mvisible=(!Mvisible);
  if (!Mvisible) return;


  if ((GetAsyncKeyState(VK_END)&1)){
   
     if(menulock == false){    
        menulock = true;}else{
           menulock = false; }
  }

  if ((GetAsyncKeyState(VK_UP)&1) && (menulock == false)) {
      do {
         Mpos--;
         if (Mpos<0)  Mpos=Mmax-1;
      } while (MENU[Mpos].typ==MENUTEXT);      // skip textitems
  } else if ((GetAsyncKeyState(VK_DOWN)&1) && (menulock == false)) {
      do {
         Mpos++;
          if (Mpos==Mmax) Mpos=0;
      } while (MENU[Mpos].typ==MENUTEXT);      // skip textitems
  } else if (MENU[Mpos].var) {
      int dir=0;
      // bugfix: thx to Dxt-Wieter20
      if ((GetAsyncKeyState(VK_LEFT )&1) && (*MENU[Mpos].var > 0) && (menulock == false)) dir=-1;
      if ((GetAsyncKeyState(VK_RIGHT)&1) && (*MENU[Mpos].var < (MENU[Mpos].maxvalue-1)) && (menulock == false)) dir=1;
      if (dir) {
         *MENU[Mpos].var += dir;
         if (MENU[Mpos].typ==MENUFOLDER) Mmax=0;  // change on menufolder, force a rebuild
      }
  }


}








Seccond part is d3dmenu.h

#endif



I'm scratching my head on why it shows up in shadow and reflections in water and also if i enable bloom. ANY help is this issue is welcome and thanks

This is the effect the d3d hook has?

Looks like it's ending up in the water and is being refracted.
I'd guess some kind of weird render-to-texture problem

Right i thought same thing.. TIL i did this


Code:
  D3DCOLOR fontColor = D3DCOLOR_ARGB(255,0,0,255);   

// Create a rectangle to indicate where on the screen it should be drawn
RECT rct;
rct.left=((dwWidth/2)-300);
rct.right=(rct.left+600);
rct.top=30;
rct.bottom=rct.top+20;
 

ostringstream ss,jj;

currenthp=75;
maxhp= 100;

ss << currenthp;
hpdata = ss.str();

jj << maxhp;
hpdata = hpdata + " / " + jj.str();

hpdata = hpdata + " HP";
// Draw some text

m_pFont ->DrawText(NULL, hpdata.c_str(), -1, &rct, DT_CENTER|DT_NOCLIP, fontColor );



This is my place holder function for where im going to hold hp

the vars
dwWidth is screen width
currenthp the current hp of object
maxhp the highest amount of hp it can have at any point
ss and jj are just vars used to convert ints to string
hpdata is the final string that gets outputted


I have no clue WHY this wont give me the same shadow or bloom effect as the menu. I looked over the code a few times and i dont know what im missing.

I also have such a problem with my Flyff d3dhook: my menu sometimes appears on tree-shadows or when a notice is shown (text in the middle of screen) it displays under the notice. (so it appears at the normal position where it should be and ALSO on those other positions)

Were you ever able to figure out why its doing that?

No, it still does that. I just turned off shadows.

I do my drawing in the EndScene() hook.
So maybe, after the game called EndScene it does some more drawing (which it shouldn't) and then maybe the menu graphic data is still stored in some buffer and the stuff that's drawn after EndScene gets mixed/blended into that buffer?

Or, maybe there are multiple render-targets set or something? Like the menu is rendered to two surfaces at the same time. So maybe just reset all those things before drawing the menu, calling functions like SetRenderTarget() and SetTexture() with the default parameters.
SetRenderTarget. It says that it can support multiple render targets (depends on video card). So get the number of supported render targets, and call SetRenderTargets(i, NULL) in a loop, on each of them. I'm just guessing here, I have no idea how the 'render target' thing works....

A typical bloom effect uses the render to texture feature, as well as stuff like water reflections, so I'd guess what you draw is getting included. For the most part, it works exactly like you'd expect.

I guess you could save them before you do your drawing and put them back to whatever. Trashing them sounds like it may be a bad idea.

So this render-to-texture thing, how to turn it off? SetTexture? or SetRenderTarget?

(Yes I meant first saving them with GetTexture/GetRenderTarget before 'trashing' them. However, the game will probably set them again in their next loop so it depends on the game if you can 'trash' them or not.)
