Proc:Trap
From WikiName
Overview
The trap procedure allows builders to combine a single trigger with multiple effects. Some effects maybe be harmful, while others helpful. The settings for the trap are assigned via the setproc command. The trap proc can be added to rooms or mobiles.
| Key | Default | Description |
|---|---|---|
| TRAP_INITIAL_CHARGES | 1 | The number of charges the trap has per zone reset. If this value is negative, the trap has infinite charges. |
Triggers
The trap may only have one trigger which is set in the TRIGGER_TYPE key value.
| Value | Description |
|---|---|
| Arrival | Activates when players enter the room. |
| Cast | Activates when the specified spell is cast at a particular target. |
| Command | Activates when players enter a particular command. |
| Departure | Activates when players attempt to leave the room. |
| HourOfDay | Activates once or every interval during a particular range of time each mud day. |
| MobileDeath | Activates when a particular mobile is killed. |
| Password | Activates when a player says a particular word. |
| PressurePlate | Activates when the sum of the weights of all players/mobiles in the room reach a particular threshhold. |
| Timer | Activates when the MUD's internal timer goes off. This occurs approximately every 10 seconds. |
| ZoneReset | Activates immediately after the zone reset occurs. |
Trigger Settings
Global settings that may be applied to the trigger.
| Key | Default | Description |
|---|---|---|
| TRIGGER_CHANCE | 100 | The percentage chance that the trigger will activate. |
| TRIGGER_MIN_PRIME_LEVEL | 0 | The minimum prime level required to activate the trigger. |
| TRIGGER_MAX_PRIME_LEVEL | 50 | The maximum prime level allowed to activate the trigger. Note that immortals will only trigger the trap if TRIGGER_INCLUDE_IMMORTALS is also set. |
| TRIGGER_ACTIVATION_DELAY | 0 | Approximate number of seconds to delay the effects after the trigger is activated. Note that setting this value allows for the player activating the trigger to escape - which means they may not be present for any of the effects. |
| TRIGGER_SPELL_EXEMPTION_LIST | No exemptions | A colon (:) separated list of spells/skills that make the player exempt from activating the trigger. |
| TRIGGER_INCLUDE_MOBILES | 0 (FALSE) | Indicates whether independant mobiles should be able to activate the trigger. If this value is left at zero, wandering mobiles will not activate the trap nor count toward cumulative activations such as pressure plate weights. Mobile followers (supplications, summoned undead, etc) are always able to activate the trigger unless their master's prime level falls outside the trigger's boundaries or unless the follower is affected by a spell in the spell exemption list. |
| TRIGGER_INCLUDE_SELF | 0 (FALSE) | Indicates whether a mobile with the trap procedure attached can trigger the procedure itself. Then must be TRUE if a mobile wishes to trigger on it's own death, for example. |
| TRIGGER_INCLUDE_IMMORTALS | 0 (FALSE) | Indicates whether immortals can trigger the trap. Best used when debugging or for helpful traps that perform tasks like opening doors. |
| TRIGGER_MESSAGE_ACTOR | No message | Message sent to the player who activates the trigger. |
| TRIGGER_MESSAGE_ROOM | No message | Message sent to the room when the trigger is activated. |
Cast
The cast trigger will activate if one of the specified spells is cast at one or more target keywords.
| Key | Default | Description |
|---|---|---|
| CAST_SPELL_LIST | None | Colon (:) separated list of spell names. |
| CAST_COMMAND_NAME | None | Either PLAY or SING if you want to force that command to be used. Otherwise the method used to cast the spell or sing/play the song is irrelevant. |
| CAST_TARGET_LIST | None | Colon (:) separated list of potential targets for the spell. Each value contains one or more keywords that must be specified to activate the trap. If this value is left empty, then the arguments are ignored and any matching spell will activate the trap. Leaving this field out of your script also uses the default setting which is 'no target' or 'None', and therefore spells that don't use a target can (and should) thus be used this way. |
Command
The command trigger will activate if a player enters the specified command and arguments.
| Key | Default | Description |
|---|---|---|
| COMMAND_LIST | None | Colon (:) separated list of commands and their arguments. |
For example, a value of push tomb:push stone:push tombstone would trigger on any of the three commands listed.
HourOfDay
The HourOfDay trigger will activate either once or once every interval during a range of hours during the day. It ignores most of the trigger settings including TRIGGER_MIN_PRIME_LEVEL, TRIGGER_MAX_PRIME_LEVEL, and TRIGGER_SPELL_EXEMPTION_LIST.
| Key | Default | Description |
|---|---|---|
| HOUR_OF_DAY_START | None | Start of the range. |
| HOUR_OF_DAY_START_MESSAGE | No message | Message to display when the hour range begins. This message is sent to the room. |
| HOUR_OF_DAY_STOP | None | End of the range. This value may not be the same as the start value otherwise the range is considered empty. |
| HOUR_OF_DAY_STOP_MESSAGE | No message | Message to display when the hour range ends. This message is sent to the room. |
| HOUR_OF_DAY_RUN_MULTIPLE | TRUE | Whether to run every interval (the default) or just once when the range begins. |
MobileDeath
The mobiledeath trigger will activate if a particular mobile is killed in this room. It ignores most of the trigger settings including TRIGGER_MIN_PRIME_LEVEL, TRIGGER_MAX_PRIME_LEVEL, and TRIGGER_SPELL_EXEMPTION_LIST.
| Key | Default | Description |
|---|---|---|
| MOBILE_DEATH_VNUM | -1 | Vnum of the mobile to react to. |
Note that if the trap procedure is added to a mobile and the TRIGGER_INCLUDE_SELF flag is set to TRUE, the MobileDeath trigger will activate the trap regardless of the MOBILE_DEATH_VNUM settings.
Password
The password trigger will activate if a player says a particular word.
| Key | Default | Description |
|---|---|---|
| PASSWORD_VALUE | (none) | The password. |
Pressure Plate
The pressure plate trigger activates when the weight of the applicable players and mobiles crosses a threshhold. Players/mobiles affected by the fly or wraithform spells are not counted.
| Key | Default | Description |
|---|---|---|
| PRESSURE_PLATE_WEIGHT | 0 | The amount of weight needed to activate the trigger. |
Zone Reset
There are no additional settings for this trigger.
Effects
Note that if a the trap has a non-zero activation time and is set to only affect the person triggering the trap, the person may be gone and the trap may affect noone.
| Key | Default | Description |

| EFFECTS_SPELL_EXEMPTION_LIST | Empty | Colon (:) separated list of spells that exempt the player/mobile from being affected by any of the trap's effects. |
| EFFECTS_LIST | Empty | Colon (:) separated list of effects enabled for this trap. Effects are activated in the order they appear. |
| EFFECTS_TARGET | Actor | A string value of "Actor" to target the person triggering the trap, or "Room" for the entire room, or a number from 1 to 32 indicating how many random eligible players/mobiles should be selected and affected. |
| EFFECTS_AFFECT_MOBILES | 0 (FALSE) | Boolean value indicating whether unrelated mobiles should be affected by the trap. If this value is left at zero, wandering mobiles will not be affected. Mobile followers (supplications, summoned undead, etc) will always be eligible unless their master's prime level falls outside the trigger's boundaries or unless the follower is affected by a spell in the spell exemption list. |
| EFFECTS_AFFECT_SELF | 0 (FALSE) | Boolean value indicating whether the mobile the trap is attached to should be affected by the trap. |
| EFFECTS_AFFECT_OBJECTS | 0 (FALSE) | Boolean value indicating whether objects in the room should be affected by the trap. |
| EFFECTS_ALLOW_DEATH | 0 | Boolean value determining whether players/mobiles can be killed by the trap. By default the player/mobile will be taken down to 0 hit points and stunned. It is strongly recommended that this only be changed in the most harshest of areas. |
| EFFECTS_OVERRIDE_COMMAND | 0 | Boolean value indicating whether activation of the trap overrides the current command. Only relevant if a command triggers and activates the trap. |
| EFFECTS_BLOCK_DEPARTURE | 0 | Boolean value indicating whether activation of the trap blocks departure of the room. Only relevant if the trap is triggered and activated by attempting to exit the room. |
| EFFECTS_SKIP_LOOK_ON_ARRIVAL | 0 | Boolean value indicating whether activation of the trap should stop the affected players from looking when arriving at their destination. Only relevant if the trap is triggered and activated during arrival into a new room. |
| EFFECTS_SKIP_REMAINING_PROCS | 0 | Boolean value indicating whether activation of the trap should stop any further procs from running for this event. |
| EFFECTS_RETURN_SUCCESS | 0 | Boolean value indicating whether the proc returns success. Currently this is only used during the CAST trigger to return whether the cast of the spell was successful or not. This allows the game to determine how much mana to subtract from the player. |
