Type definitions are the equivalent of EVENTS that can be attached to items. There are different properties that can be used to attach a type block to an item or set of items:


In addition to handling triggers, type definitions can also be used to define different types of terrain. This can be used to affect the return value of the TYPE property on map points, or for some hardcoded types such as t_rock it can be used to define which terrain IDs Sphere should consider to be rock when the mining skill is used.

Built-in Types

The built-in types are all listed in the sphere_defs.scp file. The table below only lists some of the built-in types and it is VERY weak on actual details...so use with care.

DEFNAME Number Description
t_normal 0 No built-in behavior.
t_container 1 This type is used for unlocked containers. It leverages the following properties:
  • MORE = UID of this container's key (if it has one)
  • LINK = UID of a secondary key (see t_key for an explanation of this curious fact)
t_container_locked 2 This type is used for locked containers. It leverages the following properties:
  • MORE = UID of this container's key
  • LINK = UID of a secondary key (see t_key for an explanation of this curious fact)
t_door 3 This type is used for unlocked doors. It leverages the following properties:
  • MORE = UID of this door's key (if it has one)
t_door_locked 4 This type is used for locked doors. It leverages the following properties:
  • MORE = UID of this door's key
t_key 5 This type is used for keys. It leverages the following properties:
  • MORE = UID of the item this key can unlock
  • LINK = Usually the UID of a multi (house), etc, but can also be the UID of a door

Note: Keys, containers, and doors are very odd. If both a key and a door contain the same multi UID in either MORE or LINK, the key will open the door. This is how there can be multiple doors in one house using a single key. You can also have different UIDs stored in MORE and LINK so a single key will open more than one door.

t_light_lit 6 This type is used for light sources that can be turned on or off. It leverages the following properties:
  • MOREY = Number of charges before the item is consumed
  • MOREZ = Type of light pattern it will cast

Scripted TYPEDEFs

DEFNAME File Description
t_advance_gate  ??.scp MORE = ID of character to change into

Syntax

The syntax for defining a type is:


[TYPEDEF defname]
TERRAIN=id
TERRAIN=start_id, end_id

ON=trigger_name
    script

ON=trigger_name
    script


Any number of triggers can be handled by one TYPEDEF definition, however it is not possible to handle the same trigger twice without using multiple definitions.


The trigger name can be the name of any item trigger. The return value from the script can affect Sphere's hardcoded behaviour in different ways. See the documentation for the trigger to discover what parameters are passed in to each trigger and what the return values do.


Note: If the defname matches any of Sphere's hardcoded types (see 'typedefs' block in sphere_defs.scp), then the TYPEDEF can be used to override the behaviours of items of that type.


Examples

//
// Water definition from default script pack.
//
[TYPEDEF t_water]
TERRAIN = 0a8	0ab
TERRAIN = 0136	0137

//
// Makes an item speak when double clicked.
//
[TYPEDEF t_exampletype]
ON=@DClick
    SAY I have been double clicked!
    RETURN 2
