 |
|
I hope this will be found really helpful to some people. It adds an armor attribute to the player, statusbar, and turns the suit of armor into a pickup. Let's begin.
Open VERSION.H and add the following line:
Save and close. Open WL_DEF.H and search for "keys" . You should get the gamestate structure:
| Code: |
//---------------
//
// gamestate structure
//
//---------------
typedef struct
{
int difficulty;
int mapon;
long oldscore,score,nextextra;
int lives;
int health;
int ammo;
int keys;
|
Add the following underneath int keys :
| Code: |
#ifdef ARMOR
int armor;
#endif
|
If ARMOR is defined in VERSION.H, then gamestate.armor will be defined. Now open WL_AGENT.C and
search for GiveAmmo. You should now be at the bottom of the Local Variables section. Add the
following definition at the bottom of this section:
| Code: |
#ifdef ARMOR
void GiveArmor (int points);
#endif
|
Then delete the DrawWeapon line. Now, search for the TakeDamage Routine. Edit the if(!godmode) statement to read the following:
| Code: |
#ifdef ARMOR
if (!godmode)
{
if (gamestate.armor)
{
if ((gamestate.health -= points / 3) >= 0)
{
gamestate.health -= ((int)points / 3);
if (gamestate.health > 115)
gamestate.health = 115;
}
gamestate.armor -= points / 2 + 2;
}
else
{
gamestate.health -= points;
}
}
if (gamestate.armor <= 0)
gamestate.armor = 0;
DrawWeapon ();
#else
if (!godmode)
gamestate.health -= points;
#endif
|
This tells the game that should the player have armor, the amount of damage taken is reduced.
Now, search for DrawWeapon and edit it to look like this::
| Code: |
/*
==================
=
= DrawArmor/Draw Weapon
=
= By Deathshead
==================
*/
void DrawWeapon (void)
{
#ifndef ARMOR
StatusDrawPic (32,8,KNIFEPIC+gamestate.weapon);
#else
if (gamestate.armor <=0) //didn't know where to put this, so used BW2SE source
gamestate.armor = 0; //didn't know where to put this, so used BW2SE source
LatchNumber (34,16,3,gamestate.armor);
#endif
}
|
This tells the compile that if the user has disabled ARMOR in VERSION.H, then draw the picture of
the selected weapon on the status bar. If it IS enabled, then the amount of armor the player has is
displayed instead.
Three more things to do in WL_AGENT.C . Search for bo_fullheal. You should get something like:
| Code: |
case bo_fullheal:
SD_PlaySound (BONUS1UPSND);
HealSelf (50);
GiveExtraMan ();
gamestate.treasurecount++;
break;
|
Add the following under GiveExtraMan ();
| Code: |
#ifdef ARMOR
GiveArmor (50); // Edit 50 to suit your needs
#endif
|
For that to work properly, add the following under the previously editted DrawWeapon Routine:
| Code: |
#ifdef ARMOR
/*
===============
=
= GiveArmor
=
===============
*/
void GiveArmor (int points)
{
gamestate.armor += points;
if (gamestate.armor>100)
gamestate.health = 100;
DrawArmor ();
}
#endif
|
Now, making an item for the Armor. Open up WL_AGENT.C and go back to where you editted the fullheal
case. Under that whole case, add the following:
| Code: |
#ifdef ARMOR
case bo_armor:
if (gamestate.armor >= 100)
return;
SD_PlaySound (BONUS1SND);
GiveArmor (25);
break;
#endif
|
If you wish this to contribute to the treasure count, add the following under GiveArmor (25);
| Code: |
gamestate.treasurecount++;
|
This means that for every armor pickup you collect, you gain a percentage of total treasure.
Now it's time to state how much armor you start off with. Open WL_MAIN.C and search for the NewGame
routine:
| Code: |
/*
=====================
=
= NewGame
=
= Set up new game to start from the beginning
=
=====================
*/
void NewGame (int difficulty,int episode)
{
memset (&gamestate,0,sizeof(gamestate));
gamestate.difficulty = difficulty;
gamestate.weapon = gamestate.bestweapon
= gamestate.chosenweapon = wp_pistol;
gamestate.health = 100;
gamestate.ammo = STARTAMMO;
gamestate.lives = 3;
gamestate.nextextra = EXTRAPOINTS;
gamestate.episode=episode;
startgame = true;
}
|
Underneath gamestate.health = 100; , add the following:
| Code: |
#ifdef ARMOR
gamestate.armor = 100; // Change 100 to your liking.
#endif
|
Save and Close that file then open WL_GAME.C and search for the Died Function. Scroll through that
until you find if (gamestate.lives > -1) . For some that might be if (gamestate.lives > 0) .
Add the following underneath gamestate.health = 100;
| Code: |
#ifdef ARMOR
gamestate.armor = 100; // Change 100 to your liking
#endif
|
All that's left is to choose which sprite will become the armor pickup.
Open up WL_DEF.H and search for bo_gibs, . Under that, add the following:
| Code: |
#ifdef ARMOR
bo_armor,
#endif
|
This is to define the bo_armor case you added earlier. If this isn't added, an
In this example, I will use
the suit of Armor. Open WL_ACT1.C and search for Armor. You will get the following hit:
| Code: |
{SPR_STAT_16,block}, // suit of armor spr3v
{SPR_STAT_17,block}, // Hanging cage "
{SPR_STAT_18,block}, // SkeletoninCage "
{SPR_STAT_19}, // Skeleton relax "
|
Change the Suit of Armor line to read the following:
| Code: |
#ifdef ARMOR
{SPR_STAT_16,bo_armor}, // suit of armor spr3v
#else
{SPR_STAT_16,block}, // suit of armor spr3v
#endif
|
If ARMOR is defined in VERSION.H, then the armor is a pickup. Now, if you compiled then tried this, you would find that the knight is transparent, but not yet a pickup. For that to happen, we have to add one more thing. In WL_ACT1.C search for 'bo_firstaid:' in the SpawnStatic Function. Underneath that line, add:
| Code: |
#ifdef ARMOR
case bo_armor:
#endif
|
That concludes my tutorial. If you use this, let me know, and email me at deathshead.frozenfire@gmail.com , I would like to see your mod!
There you go
