TYPEDEF

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:

• item definitions via their TYPE and/or TEVENTS property.
• items via their TYPE and/or EVENTS property.

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 and t_container_locked	1 and 2	These types are used for containers. They leverage the following properties: MORE1 = "ID" from the key that can unlock this item (If the MORE1 of the key matches the MORE1 of the container then they are linked) MORE2 = The lock complexity (how hard it is to pick the lock) MOREX = The trap type (not used yet?) TDATA2 = The gumpID for the container (this is not a ITEMDEF) TDATA3 = The minimum gump size TDATA4 = The maximum gump size LINK = UID of a secondary key?
t_door or t_door_unlocked	3 or 4	This type is used for both locked and unlocked doors. They leverage the following properties: MORE1 = UID of this door's key (if it has one)
t_key	5	This type is used for keys. It leverages the following properties: MORE1 = "ID" of the item(s) this key can unlock (if the MORE1 of the key matches the MORE1 of the container/door then they are linked) LINK = If this is set to the UID of a "multi" object (like a house) the key can open all doors/containers in that multi? Note: Keys, containers, and doors are interesting. If both a key and a door/container contain the same arbitrary MORE1 value, the key can be used to lock or unlock the door/container. That action changes the TYPE of the door/container to indicate whether it is locked or not. It also seems like LINK on the key can be set to the UID of a multi so that it can be used to open all doors/containers inside that multi.
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

It leverages the following properties: MORE1L = Max hitpoints MORE1H = Current hitpoints MOREX = Spell effect when worn (for example, setting MOREX=1 causes a permanent Clumsy effect) MOREY = There are two possible effects of setting MOREY: If MOREX is set, then MOREY is the power/effect of that spell If the ATTR includes attr_magic, then there is an AR bonus (how is this calculated?) Note: Old versions of sphere stored remaining charges in MORE2, this is no longer true.

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
