1102 |

|
* eg, the player or monster. |
1103 |
|
|
* caster is the actual object (wand, potion) casting the spell. can be |
1104 |
|
|
* same as op. |
1105 |
|
|
* dir is the direction to cast in. Note in some cases, if the spell |
1106 |
|
|
* is self only, dir really doesn't make a difference. |
1107 |
|
|
* spell_ob is the spell object that is being cast. From that, |
1108 |
|
|
* we can determine what to do. |
1109 |
|
|
* stringarg is any options that are being used. It can be NULL. Almost |
1110 |
|
|
* certainly, only players will set it. It is basically used as optional |
1111 |
|
|
* parameters to a spell (eg, item to create, information for marking runes, |
1112 |
|
|
* etc. |
1113 |
|
|
* returns 1 on successful cast, or 0 on error. These values should really |
1114 |
|
|
* be swapped, so that 0 is successful, and non zero is failure, with a code |
1115 |
|
|
* of what it failed. |
1116 |
|
|
* |
1117 |

|
* Note that this function is really a dispatch routine that calls other |
1118 |
|
|
* functions - it just blindly returns what ever value those functions |
1119 |
|
|
* return. So if your writing a new function that is called from this, |
1120 |
|
|
* it shoudl also return 1 on success, 0 on failure. |
1121 |
|
|
* |
1122 |
|
|
* if it is a player casting the spell (op->type == PLAYER, op == caster), |
1123 |
|
|
* this function will decrease the mana/grace appropriately. For other |
1124 |
|
|
* objects, the caller should do what it considers appropriate. |
