Creating spell that gives a Skin/Transform to player - Like Demon Skin Glitch was created by wlessard1

So I setup the applies for the Demon Skin. It is working fine except for one thing.

When I do a apply_hit or apply_move and try and put MORE than 100 as the modifier, it ends up giving me a negative number to the Maxhits/Maxmoves.

case SPELL_DEMON_SKIN:
af[0].location = APPLY_AC;
af[0].duration = 1 + (GET_LEVEL(ch) / 2);
af[0].modifier = -50;
SET_BIT_AR(af[0].bitvector, AFF_DEMON);

af[1].location = APPLY_HITROLL;
af[1].duration = 1 + (GET_LEVEL(ch) / 2);
af[1].modifier = (GET_LEVEL(ch))/4;
SET_BIT_AR(af[1].bitvector, AFF_DEMON);

af[2].location = APPLY_DAMROLL;
af[2].duration = 1 + (GET_LEVEL(ch) / 2);
af[2].modifier = (GET_LEVEL(ch))/4;
SET_BIT_AR(af[2].bitvector, AFF_DEMON);

af[3].location = APPLY_HIT;
af[3].duration = (GET_LEVEL(ch) / 2);
af[3].modifier = 200;
SET_BIT_AR(af[3].bitvector, AFF_DEMON);

af[4].location = APPLY_MOVE;
af[4].duration = 1 + (GET_LEVEL(ch) / 2);
af[4].modifier = 200;
SET_BIT_AR(af[4].bitvector, AFF_DEMON);

to_vict = "You skin becomes leathery.";
break;

Results -- If I see the modifier to 100, it works fine but anything over that produces a negative to maxmove and hits, probably maxmana as well.

Affected by: DEMON
SPL: ( 29hr) Demon Skin -56 to MAXMOVE, sets DEMON,
SPL: ( 28hr) Demon Skin -56 to MAXHIT, sets DEMON,
SPL: ( 29hr) Demon Skin +13 to DAMROLL, sets DEMON,
SPL: ( 29hr) Demon Skin +13 to HITROLL, sets DEMON,
SPL: ( 29hr) Demon Skin -50 to ARMOR, sets DEMON,

I would like to be able to run the modifier up a bit higher as I want to add some other spells that do things like this.

Stock TBAmud has the following in structs.h

Code:

/** An affect structure. */
struct affected_type
{
  sh_int spell; /**< The spell that caused this */
  sh_int duration; /**< For how long its effects will last      */
  sbyte modifier;  /**< Added/subtracted to/from apropriate ability     */
  byte location;   /**< Tells which ability to change(APPLY_XXX). */
  int bitvector[AF_ARRAY_MAX]; /**< Tells which bits to set (AFF_XXX). */

  struct affected_type *next; /**< The next affect in the list of affects. */
};

sbyte is defined in structs.h as:

Code:

typedef signed char sbyte;          /**< 1 byte; vals = -127 to 127 */

If you want larger values for affect.modifier[] you will need to change it to something like sh_int or ubyte.

I'n my game I went with sh_int:

Code:

/** An affect structure. */
struct affected_type
{
  sh_int spell;                /**< The spell that caused this */
  sh_int duration;             /**< For how long its effects will last      */
  sh_int modifier;             /**< Added/subtracted to/from apropriate ability     */
  byte location;               /**< Tells which ability to change(APPLY_XXX). */
  int bitvector[AF_ARRAY_MAX]; /**< Tells which bits to set (AFF_XXX). */

  struct affected_type *next; /**< The next affect in the list of affects. */
};

You could use ubyte or sh_int, whichever suits your fancy. They are defined as:

Code:

typedef unsigned char ubyte;        /**< 1 byte; vals = 0 to 255 */
typedef signed short int sh_int;    /**< 2 bytes; vals = -32,768 to 32,767 */

Hope this helps
