RED Objects

Objects can make or break a level. The addition of objects to a level helps to provide a better reference for scale, as well as giving a level a more realistic feel. Objects are classed as any 3D thing in a level that is not made from level geometry, and there are several different categories of objects, ranging from characters to vehicles to light fixtures and weapons. Objects can be manipulated in Object Mode or Group Mode.

This page lists available object types in RED. For specifics on Object Mode in RED, see the Object Mode Overview.

Events

The event/scripting system for Red is very powerful, yet easy to use. The basic philosophy behind it is that you LINK a TRIGGER to an EVENT(s). This system is very versatile and will let you create an almost unlimited number of special scripted sequences.

An "Event" is a basic game action that occurs when it receives either an On and/or Off message. On messages can be sent from triggers, objects, or they can be received from other Events. Off messages are sent from the off state of events like the Switch Event, or are sent through an Invert Event. Most Events only respond to On messages (since most Events do a single thing which doesn’t need to be stopped with an Off message). Events must be linked to the trigger source so they know when to trigger. You link a trigger and event together by using the objects unique id number, or by just selecting the first object, then the second object, and hitting the "K" hot-key.

Events can also be linked to other Events to set up a "Chain reaction" of event all triggered from one source. For example, you might have a trigger which links to a Play_Sound Event (which plays a scream), and the Play_Sound Event could link to a Play_Animation Event (which plays an animation of an AI holding his head in agony).

All Events have an optional delay associated with them, which you can specify in the Event properties (CTRL-P or by right clicking over the selected event and selecting "Properties" from the pop-up menu). This will delay the action of the event by the specified amount of time, after an On or Off message is received.

Events can link to other objects, which is used to tell the Event which objects to affect. Each Event affects their linked objects in different ways, so refer to the Event list below for a detailed description of each event. The link HAS to go from the event to the object for it to work- even if the object is being used at the "trigger"!

Event Types

• See RED Event List for a comprehensive list of event types and their functions.

Entity

Entities include all characters, vehicles, turrets, and cameras in the game.

Properties

Entity Options

Entities include all characters, vehicles, turrets, and cameras in the game. Available entity properties are listed below.

• Class Name: What entity class this entity is (from entity.tbl). The list of entity classes is accessible in the editor via the "Entity" tree in the Object list.
• Script Name: Name for entity. This is used primarily for the designer to help organize entities.
• AI Mode: Default AI behavior for the entity:
  • Catatonic: Entity will not react to anything in the world.
  • Waiting: Entity will react to enemies that are seen, and will react to sounds (if not flagged as Deaf)
  • Waypoints: Entity is following waypoints (waypoint list is specified via Waypoint List field described below, or through a Follow_Waypoints Event)
  • Collecting: Entity is picking up and collecting clutter (usually rocks) and dropping them off at a specific location. This is currently used for grabber robots that collect rocks and deposit them in rock crushers.
  • Motion Detection: Entity will attack any moving objects that it has line of sight to. This is currently used for unmanned turrets.
• AI Attack Style:
  • Evasive: Entity will move evasively while attacking target.
  • Direct: Entity will move directly towards target when attacking.
  • Stand Ground: Entity will stay rooted to it's current position while attacking, and will not pursue targets.
• Min Attack Dist: The distance that an entity must be to a target to open fire (in meters). For example, if you only wanted an enemy to open fire if within 10 meters of a target, then specify 10 for the min attack dist.
• FOV: Field-of-view for the entity. The default FOV for the entity is specified in entity.tbl ($FOV), but you can adjust it here to simulate an entity being having reduced peripheral vision.
• Life: The hit points for the entity. The default value is their max life. You can reduce the life of an entity to simulate the entity being injured, or to make certain scripted sequences work better (e.g., you want an entity to die after being hit once).
• Cooperation: Currently not used.
• Friendliness: Alignment for this entity. The player and allies are Friendly. Entities hostile to the player are considered Unfriendly. Neutral is used for entities which won't attack the player on sight, but they also won't help the player when attacked. Outcast is used for entities which attack all other entites, including other Outcast entities.
• Default Primary: Weapon class (from weapons.tbl) that the entity is using for a primary weapon.
• Default Secondary: Weapon class (from weapons.tbl) that the entity is using for a secondary weapon. Currently only vehicles and some robots utilize secondary weapons.
• Item Drop: Item class name (from items.tbl) that the entity will drop when killed.
• State Anim: Animation state that entity is forced to be in. State animations are looping, so the entity will remain in this animation state until attacked or given scripted instructions.
• Corpse Pose: If specified, entity will be created as a corpse in this position. This is how corpses are placed by the designer.
• Death Anim: Death animation that is forced to play when entity dies.
• Skin: Texture set to use for the entity. When you place an entity, a random skin is selected. Alternate skins are specified in entity.tbl ($Skin).
• Team ID: Currently not used.
• Waypont List: Name of the waypoint list that the entity will follow (if their AI mode is set to Waypoints).
• Waypoint Method: How the entity should follow waypoints
  • One Way: go from first to last waypoint and stop
  • Loop: go from first to last waypoint, and repeat (go directly from last to first waypoint)
  • Ping Pong: go from first to last waypoint, then follow waypoints backwards back to first waypoint, and repeat
• Path Follow Style: Currently not used.
• Sweep Min/Max Angle: This is used by entities that sweep back and forth as part of their default behavior (security cameras, motion detecting turrets). The angle is specified in degrees, and is relative to zero degrees. The min angle must always be less than the max angle.
• Turret UID: If specified, this is the UID for a turret that the entity should be attached to (i.e., is using).
• Alert Camera UID: If specified, this entity will be alerted to the player when the specified camera sights the player. This is used to simulate guards being alerted to the player via security monitors.

Entity Flags

• Only Attack Player: Entity will only attack the player. It will never attack other AI, even if attacked.
• Weapon Is Holstered: Entity has weapon holstered by default. The weapon is still available for the entity to use, but it must be unholstered first.
• Ready To Fire State: Entity is posed in a ready to fire animation state.
• Ignore Terrain When Firing: Entity doesn't do collision detection with terrain when deciding to fire on targets, once target is sighted initally through line of sight. This is useful for large turrets or other weapons which you want to keep firing even if the player is hidden by cover.
• Hidden: Entity is hidden. This means the entity isn't visible. No AI or physics of any kind is applied to the entity.
• Cower From Weapon: Entity will flee and cower if it sees an entity of different friendliness with an unholstered weapon.
• Question Unarmed Player: Entity will question the presence of the player if he is unarmed.
• Deaf: Entity does not hear, so it will not investigate or react to sounds.
• Boarded (vehicles only): Entity is boarded. This is used to indicate that vehicles are manned by AI.
• Wear Helmet: Entity wears a helmet if one is defined for that entity class in entity.tbl ($Helmet V3D Filename).
• End Game If Killed: Game ends if this entity is killed. When the entity is killed, the game cuts to a black screen with scrolling text. The scriptname of the entity determines what text is displayed. The text for various scriptnames is defined in endgame.tbl. This means that you must have a unique scriptname for an entity that has this flag set.
• Start Crouched: Entity begins crouched.

Keyframe

The editor uses keyframes as the method for animating how moving groups move. They are a way to tell the game engine where the mover should go and in what order. You also use the keyframes to tell the mover how fast to go to the next keyframe, if the mover should reverse or start the process over when it finishes, and other such information.

Properties

• Is Door: Set this flag for a Translating or Rotating Mover that's used as a door so it will block visibility when it's closed. A door is considered "closed" then the mover is at the the gold keyframe.
• Start Moving Backwards: This flag causes a translating mover to start at its last keyframe and go backwards through the keyframe list. On a rotating mover, it will start at its final position.
• Rotate In Place: Set this flag for creating a Rotating Mover.
• Use Travel Time as Velocity: This flag uses the values in "Departing Travel Time" and "Return Travel Time" to set a mover's speed (meters per second).
• Force Orient: Not Supported.
• No Player Collide: This flag causes the mover to not do collision detection.
• Propagate Sounds: This will make all keyframes that have the same script name as the currently selected keyframe have the same sounds. This will not affect keyframes with the script name of "keyframe".
• Propagate Properties: This will make all keyframes that have the same script name as the currently selected keyframe have the same properties. This will not affect keyframes with the script name of "keyframe".
• Stop Sounds: This will cause all looping sounds that have been activated by a "Preview" button to stop playing.
• Movement Type: Defines the movement behavior for the keyframe list. The movement types are explained below:

Movement Type	Translating	Rotating
One Way	Goes from first to the last then stops until it receives a turn on message again. e.g. 1 > 2 >3 - STOP	Goes from start to finish then stops until it receives a turn on message again. e.g. START > FINISH - STOP
Ping Pong Once	Goes from first to last then back again then stops until it receives a turn-on message again. e.g. 1 > 2 > 3 > 2 > 1 - STOP	Goes from start to finish then back to start until it receives a turn-on message again. e.g. START > FINISH > START - STOP
Ping Pong Infinite	Goes from first to last then back again until it receives a turn-off message again. e.g. 1 > 2 > 3 > 2 > 1 etc.	Goes from start to finish then back to start then loops e.g. START > FINISH > START LOOP
Loop Once	Goes from first to last then back to first then stops. e.g. 1 > 2 > 3 > 1 - STOP	Same As Ping Pong Once
Loop Infinite	Goes from first to last then back to first and repeats until it receives a turn off message. e.g. 1 > 2 > 3 > 1 > 2 > 3 etc.	Goes from start to finish then loops. e.g. START > FINISH > LOOP

• Starting Keyframe: This will determine the keyframe a mover will start at. This does not affect rotation movers. Also used conjunction with the "Preview" button to show a mover at a specific keyframe in the editor.
• Preview: This will show the mover (in the editor) at the keyframe specified in "Starting Keyframe".
• Start Sound: This is the sound that is played when a mover starts moving.
• Looping Sound: This is the sound that is played when a mover is moving between any keyframes in it's keyframe list.
• Stop Sound: This is the sound that is played when a mover either stops or pause at a keyframe.
• Close Sound: This is the sound that is played when a mover that is flagged as a door reverses direction.
• Volume: Each value will set the volume for the respective sounds. Default is 1.00
• Preview: Click this button to preview the respective sound in the editor. This only works if you have extracted the sounds from the audio.vpp file.
• Script Name: Enter a custom script name to allow sounds and properties to be propagated to other keyframes with same custom script name.
• Pause Time: This sets the time a mover will pause at the currently select keyframe. This only works on silver keyframes.
• Departing Travel Time: This is the time it will take a mover to go from the currently selected keyframe to the next keyframe.
• Return Travel Time: This is the time it will take the mover to go from the previous keyframe to the currently selected keyframe.
• Acceleration Time: This is the time it takes the mover to reach maximum velocity.
• Deceleration Time: This is the time it will take the mover to reach zero velocity.
• Trigger Event with UID: You can specify an event's UID so that when the mover reaches this keyframe, it will send a turn-on message to the event.
• Contains Item UID(s): If you create a container (like a locker or crate), you have to specify the UID(s) of the object(s) here so the item(s) cannot be picked up until the container is opened.
• Degrees About Axis: This is where you specify the amount a rotating mover rotates.
• OK: Click this to confirm any changes you have made and close the dialog box.
• Cancel: Click this to close the dialog box and lose any changes you have made.
