TDM Movers

For The Dark Mod, we extended the existing idMover class by a set of classes specifically designed for creating maps in the medieval steampunk setting. Apart from elevators, most movers in TDM are two-state movers, meaning that they can be either in "open" or "closed" state. The class hierarchy is depicted here (I use the internal C++ class names here):

There are two base classes: BinaryFrobMover and MultiStateMover, which both build on top of the vanilla Doom 3 idMover class and provides all the methods needed to make all kinds of two- or multistate movers.

Each following section is dedicated to a certain subclass, listing information about spawnargs, script events as well as the C++ methods. This article is going to be long and should probably be split into pieces once the rough shape is formed.

CBinaryFrobMover

The corresponding entityDef is atdm:mover_binarymover_base

This is the base class for all kind of TDM movers like doors, levers and buttons. The class is designed for movers with two final states, namely open and closed. "Open" and "closed" are abstract definitions and just refer to the "one" and the "other" state of the mover. All movers are considered to spawn "closed", until specifically specified otherwise.

The class provides a set of virtual C++ methods which can be specialised by their subclasses to implement the correct behaviour. It also supports a number if spawnargs which allow for easy customisation right in the editor.

Spawnargs

• rotate: Describes the angles (pitch, yaw, roll) the mover will rotate from its closed to its open position (default is: "90 0 0").
• translate: Describes the relative movement of the origin from the closed position to the open position (default is "0 0 0" = no movement).
• translate_speed: Is the linear velocity in units per second (defaults to "0", which means that the idMover's "move_time" value is in effect).

• open: (1/0) Specifies whether this frobmover spawns at the open position. Can be used to let doors be open right at map start (default is "0").
• locked: (1/0) Specifies whether this frobmover is locked (default is "0").

• open_on_unlock: (1/0) When set to 1, the mover will automatically open when unlocked.
• interruptable: (1/0) When set to 1, the mover can be stopped by frobbing it while moving. Doors are interruptable by default, whereas levers are not.
• stop_when_blocked: (1/0) Set stop_when_blocked to 0 to let this entity keep moving after the blocking entity is out of the way. Default is "1".
• push_player: (1/0) Set this to 1 to let this entity push the player (default is 0). Note: belongs to idMover class.

• start_rotate: (Angles) Defines the angles (pitch, yaw, roll) the mover should have at spawn time (to let the mover start out half-open, for instance). Defaults to "0 0 0".
• "start_position": (Vector) Defines the position the mover should have at spawn time (to let the mover start out open, for instance). Defaults to "0 0 0".
• first_frob_open: (1/0) This helps to disambiguate the behaviour when a mover starts at a half-open position. When this is set to "1" the first frob will make the mover open. Defaults to "0", which means that half-open doors will close on first frob by default.

• snd_open (Soundshader) The sound to be played when the door starts to open after being fully closed.
• snd_close (Soundshader) The sound to be played when the door reaches its fully closed position.
• snd_locked (Soundshader) The sound to be played when the mover becomes locked.
• snd_unlock (Soundshader) The sound to be played when the mover unlocks.

• trigger_on_open: (1/0) If set to "1", this binary mover will trigger its targets when it starts out completely closed and is opened. Default is "0".
• trigger_on_close: (1/0) If set to 1, this binary mover will trigger its targets when it completely closes after being open. Default is "0".
• trigger_when_opened: (1/0) If set to 1, this binary mover will trigger its targets when it is completely opened. Default is "0".

• auto_close_time: Set this to something >= 0 to let the mover automatically close (again) after this time when being fully opened (measured in seconds). Defaults to -1, which means 'do not autoclose'. The event is also activated when the mover starts at the open position at map start.
• auto_open_time: Set this to something >= 0 to let the mover automatically open (again) after this time when being fully closed (measured in seconds). Defaults to -1, which means 'do not autoopen'. The event is also activated when the mover starts at the closed position at map start.

• impulse_thresh_open: (float)
• impulse_thresh_close: (float)
• impulse_dir_open: (vector)
• impulse_dir_close: (vector)

• state_change_callback: (script function) Defines the (global) script function which gets called when the mover changes its state. Function signature is: void statChangeCallback(entity self, bool open, bool locked, bool interrupted);

CFrobDoor

Spawnargs

• loss_open (float) Defines the sound volume loss in dB when this door is open (default: 1).
• loss_closed (float) Defines the sound volume loss in dB when this door is fully closed (default: 15).
• loss_double_open (float) Defines the sound volume loss in dB when one of the double doors is open and the other is closed (default: 1).
