trigger_always


A trigger that is always on, and starts when the level begins.


keypairs

target: the thing you are triggering

killtarget: after triggering the target once, it destroys the ent

delay: the time between firings



trigger_counter


A trigger that allows for multiple inputs. This means the trigger will only fire when multiple different inputs are satisfied. As an example, if you want a door to open only when two different buttons are pressed. First make the door and give it a targetname of door1. Then make a trigger_counter and set the target to door1, targetname to counter1, and count to 2. Now create two func_buttons and set their target to counter1.


keypairs

target: the thing you are triggering

targetname: the name of the trigger

count: the number of actions that are required to fire the trigger


spawnflags

1 nomessage: typically the counter will display how many items are left, this will disable those



trigger_elevator


This is by far one of the more annoying entities to use and setup, but provides a pretty neat function once you do. It is as the name implies, an elevator. You can setup buttons at each floor and call the elevator to it. Before you start making the elevator, you must know how each of the following work, and be comfortable using them:


Usage

  1. Place a trigger_elevator somewhere in the map. This is not the elevator platform, and will not be visible. Give the trigger_elevator a targetname of elevator and a target of train.

  2. Now create the actual elevator platform. This can be a simple square or something more elaborate. When you are finished turn the entire platform into a func_train. Give the func_train the targetname of train so it will be targetted by the trigger_elevator. Then give it a target of p1, which will be the first path_corner.

  3. Now create the actual path_corner and give it a targetname of p1 to link it to the func_train. Place this on the lowest floor the elevator will go to. Repeat this for each floor, and give each one a targetname according to the floor, p2, p3, p4, etc.

  4. Each path_corner needs a pathtarget keypair. Give each one a name like stop1 for each floor.

  5. Now we need to create a func_button for each floor. Give each button a target of elevator as that is what we named the trigger_elevator.

  6. Each func_button also needs a pathtarget that you want the elevator to stop on when pressed. For instance, for the bottom func_button on floor 1, you will want to make the pathtarget set to p2 as that is the name of the 2nd floor path_corner. Then so and so forth. Basically, you want to set the path_target of each floor to the floor you want it to go to next.

  7. If you want to setup buttons to call the elevator to your location, set a func_button’s pathtarget to floor the button is on.



trigger_gravity


This is a trigger that affects the gravity of the level. In vanilla quake 2, this only affects non-player entities. However, in jumpmod it was modified to work with players, and not entities.

Using it is very simple, just create a brush the size of the area you want to change gravity in. Alternatively, you can create the trigger over the exit a teleporter or in a confined space the player has to pass through. A downside of this trigger is that gravity does not reset when the player respawns. To combat this, just place another trigger_gravity over the player spawn. The default gravity you need to set is 800.


keypairs

gravity: default 800, it can be set negative to make a player float up



trigger_hurt


A trigger that hurts the player when they enter it.


keypairs

dmg: Default 5, how much damage the trigger will do.


spawnflags

1 start_off: the trigger doesn’t work until triggered on

2 toggle: the trigger can be turned on and off

4 silent: supresses the sounds the trigger makes

8 no_protection: damage goes directly to health, even if the player has armor, or any other form of protection

16 slow: the damage ticks are slower



trigger_key


This is used in combination with key entities. It is used to gate a door or trigger behind the player having a specific key. It does not work in jumpmod as the keys have been reworked to use as checkpoints instead. Using this item is a little counterintuitive, so an example is the easiest way. We will use a key_data_spinner to stop a fan.

  1. Make the fan using a func_rotating and give it a targetname of fan.

  2. Place a trigger_key somewhere and give it a target of fan. Also give it a targetname of key.

  3. Now give the trigger_key the item keypair with the value key_data_spinner.

  4. Wherever you want the player to bring the key to must have a trigger that triggers the trigger_key. In this case, set the target to key.


keypairs

item: used to specify the key you need, the options are on the key page above



trigger_monsterjump


An entity that can only be triggered by monster. It will make the monster jump in the specified direction, speed, and height.


keypairs

angle: the angle that the monster will jump

speed: default is 200, the speed thrown in the angle from above

height: default is 200, the height thrown upward



trigger_multiple


A trigger that can be fired multiple times. Used extensively along with trigger_once for every single map. It is the basis of many contraptions and has many different types of uses.


keypairs

target: the name of the ent this is triggering

targetname: used if also using the triggered spawnflag, as it must be triggered into existance by another ent

sounds: the sound that plays when triggered; 1 = secret, 2 = beepbeep, 3 = large switch

message: a message to display to players

delay: this is the time in seconds between touching the trigger and it firing

killtarget: will remove any entity that has a matching targetname

wait: default is 0.2, amount of time between firings


spawnflags

1 monster: allows monster and players to use the trigger

2 not_player: allows only monsters to use the trigger

4 triggered: the trigger must be triggered into existance before it can be used



trigger_once


Similar to a trigger_multiple, but only fires once before removing itself from the world. Refer to trigger_multiple on how to use this. The only differences are that the keypair wait, and the spawnflag monster do not function.



trigger_push

This is used to push the player in any direction.


keypairs

speed: default 1000, the speed at which you are launched

angle: -1 for up, -2 for down, the rest are normal

angles: you can also set a 3d angle much like in info_player_intermission which means you can send players at diagonals. A great example of this is in the castlejumps map.


spawnflags

1 push_once: the ent only pushes one time, and then deletes itself from the map



trigger_relay


Used to relay actions. It cannot be triggered by a player walking through it, which means it must have both a target and targetname. An example of use for this ent is to have a crate, that when shot, causes other nearby crates to explode. You would create a func_explosive crate, and give it a target that targets a trigger_relay. The relay would then target multiple other func_explosive crates.


keypairs

target: the ent the trigger_relay is triggering

targetname: the ent that triggers the relay

delay: the amount of time between being triggered and firing

killtarget: permanently destroy the ent listed in the target keypair

message: the message that displays when fired
