/*QUAKED func_breakable (0 .5 .8) CHIPPABLE UNBREAKABLE EXPLOSIVE UNKICKABLE TOUCHY
Breakable object entity that breaks, chips or explodes when damaged.
-------- KEYS --------
health : determines the strength of the glass (default 5).
id : a unique identification. Each type of breakable in a given map needs to have a separate id. Valid values are 0 through 63.
type : type of breakable. See notes below.
amount : sets the number of fragments to generate when the entity breaks. 0 ~ 10 pieces; 1 ~ 25 pieces; 2 ~ 50 pieces; 3 ~ lots of pieces (default 0).
damage : sets the amount of damage dealt to nearbly players if the entity is made to be explosive (default 100).
damage_radius : sets the maximum distance from the explosion players will take damage (default 128).
-------- SPAWNFLAGS --------
CHIPPABLE : little pieces will spawn when the entity is shot.
UNBREAKABLE : entity will never break. To make the entity chip, but never break, check the first two spawnflags. To make the entity chip and eventually break, only set the first spawnflag.
EXPLOSIVE : entity will explode.
TOUCHY : entity will break when touched. If damage is set to a non-zero value, it specifies the damage to be inflicted to the touching entity
-------- NOTES --------
Breakables are defined in sets by the 'type' key (e.g. type : glass, type : wood). Each type used in a map must be given a unique id number. Each entity of a particular type must have the same id number (i.e. if your first glass breakable has id : 1, then every glass breakable must have id : 1). To add custom breakables, use this format:
Models: breakables/type/models/break1.md3, breakables/type/models/break2.md3, breakables/type/models/break3.md3
Type is the value set in the type key. No more, no less than three models are required. The names must be break#. Texture/shader information is contained in the .md3 file just like regular mapobjects.
Sounds: breakables/type/sounds/break1.wav, breakables/type/sounds/break2.wav, breakables/type/sounds/break3.wav, breakables/type/sounds/explosion.wav
Type is the value set in the type key. No more, no less than three break sounds are required. The names must be break#. If the entity will be exploding (explosive : 1), then the explosion.wav sound must be included as well.
Explosion graphic: breakables/type/explosion/texture
Type is the value set in the type key. Texture is any texture(s) referenced by the explosion shader. The shader script should be added to yourmap.shader.
If you wish to add a custom breakable to your map, please include your mapname (or perhaps 3 letters of it) in the type name to prevent conflicts (i.e. don't use 'brick', use 'tequila_brick' or just 'teq_brick'). See the breakables folder included in Reaction for the proper format.
