[code] defusable bombs...

This is a really easy tutorial...
Though I suppose in this tutorial that you have enabled WSJs
in-game messages and Flamer46s timer display.

We start from WL_Def.H. Add these lines in the end of the file:

Code:


//--Bomb variables

int bombs;
int bombcount;

int active;
int deact;

int test;

//--


Now open WL_Agent.C (the main code is implemented here),
and search for "Thrust" (without quotes). Now in the end of the
function add these lines:

Code:


if(*(mapsegs[1] + offset) == 399)  //399 is the objects ID 
{
  if(!test) //Well, this isn't really needed
  {
    switch(gamestate.mapon) //If you want the object to act differently
    {                                    //from level to level
      case 1:
          if(deact==true){}      //Do nothing...
          else                          //Bombs defused
          {
            if(!active) //Bombs activated?
            {
                active = true;
                test = true;               
    gamestate.finaltime = 70l*70; //Set TimerDisplay: 2min
    GetMessage("2 minutes time to defuse the bombs");
            }
          }
        break;
        default: break; //If map isn't defined
    }
  } 
}


This code activates the bombs... Now to make them "defusable",
go to the Cmd_Use function (still in WL_Agent.C)
and underneath this block:

Code:


//
// use elevator
//
  buttonheld[bt_use] = true;

//--
    gamestate.finaltime = 0; //Remember to add this!!!
//--
    tilemap[checkx][checky]++;   // flip switch
    if (*(mapsegs[0]+farmapylookup[player->tiley]+player->tilex) == ALTELEVATORTILE)
          playstate = ex_secretlevel;
    else
          playstate = ex_completed;
      SD_PlaySound (LEVELDONESND);
      SD_WaitSoundDone();
}


Add these lines (note: this is based partly on Dugtrios "opening crates"
code, so remember to credit him too) directly under it:

Code:


for(statptr = &statobjlist[0]; statptr != laststatobj; statptr++)
{
  if(statptr->tilex == checkx && statptr->tiley == checky &&
    statptr->shapenum == SPR_STAT_X1 && !buttonheld[bt_use])
  {
    buttonheld[bt_use] = true;
    statptr->shapenum = SPR_STAT_X2;

    SD_PlaySound(BONUS1UPSND);
    bombs = bombs+1; //also bombs++; works
    switch(bombs) // for different messages
    {
          case 1: GetMessage("Bombs defused 1/4"); break;
          case 2: GetMessage("Bombs defused 2/4"); break;
          case 3: GetMessage("Bombs defused 3/4"); break;
          case 4: GetMessage("All bombs are now defused.");
                    deact=true; break;
      }
      if(bombs >3) // All bombs defused... No need for timer
        gamestate.finaltime=0;
  }
}


Note: "SPR_STAT_X1" and "SPR_STAT_X2" are the definitions for
the active bomb and the defused bomb... Change the X1,X2 to match
the sprite you have selected (make sure they're blocking ones in WL_Act1.C)...
Or you can just define new sprites in the source.

Then the final touchups. Open WL_Play.C, and scroll down to "Playloop" and add
these lines in to it:

Code:


if(active)
  {
  bombcount += tics;
  if(bombs <4) //Check wether all bombs are defused in time.
  {
      if(bombcount > 70l*70) //two minutes
      {  playstate = ex_died;//kill player
                        active = false;
      }
  }
  else //Player made it on time
  {
      bombcount = 0;
      active = false;
      deact = true;
  }
}
#endif


Now last thing to do is to add these line:

Code:


 active = false;
 gamestate.finaltime=0;
 bombcount=0;
 bombs = 0;
 deact = false;


to the "NewGame" - function in WL_Main.C and in the
"Died" - function in WL_Game.C...

Now you just need to compile and you're ready to go...
In case I didn't forgot to mention something.

you say this is easy? wow, heh because you're really good in coding.

I loved this feature in Operation Wintersturm, good work!

@ Wolf3D Fan - Its just a matter of copy and pasting the code and defining the sprites.

No? I dont understand how you all make codes.. heh I only maded changing the amount of otto's rockets.

hm...it requires understanding of the code.
anyways, nice work. who is flame?
i remember the time stuff in double trouble, though i never used it...

hmmmm i keep on getting "Undefined symbol 'statptr' "

Have you defined the statpr to the beginning of CMD_Use?
