Proc:Trap

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.

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
Generic	Activates when players enter the room or perform a command.
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.

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	40	The maximum prime level allowed to activate the trigger.
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_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.

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.

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.

EFFECTS_AFFECT_OBJECTS	0	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.

Enabling the Trap

Before the trap will be enabled, you must run the following commands:

• setproc room # PROC_ENABLED 1
• compile

Compiling will copy all the KVP into an internal data structure for faster execution. Failure to compile the trap after modifications will cause any old settings to remain in effect.

In addition, setting PROC_DEBUG to 1 will send extra debugging information to those in the room.
