/*QUAKED func_breakable (0 .8 .5) ? x x x x INVINCIBLE x x x REPAIRABLE NOORIGIN
-----DESCRIPTION-----
When destroyed, fires it's trigger and explodes
When repaired just fires it's targets so things like forcefields get turned back on

-----SPAWNFLAGS-----
1: DO NOT USE! This may come in conflict with shared functions from misc_model_breakable.
2: DO NOT USE! This may come in conflict with shared functions from misc_model_breakable.
4: DO NOT USE! This may come in conflict with shared functions from misc_model_breakable.
8: DO NOT USE! This may come in conflict with shared functions from misc_model_breakable.
16: INVINCIBLE - can only be broken by being used
32: DO NOT USE! This may come in conflict with shared functions from misc_model_breakable.
64: DO NOT USE! This may come in conflict with shared functions from misc_model_breakable.
128: DO NOT USE! This may come in conflict with shared functions from misc_model_breakable.
256: REPAIRABLE - can be repaired with hyperspanner, requires an origin brush
512: NOORIGIN   - used for retrofitting repairability on func_breakables with no origin brush, do not use for new maps

-----KEYS-----
"targetname" - entities with matching target will fire it
"paintarget" - target to fire when hit (but not destroyed)
"wait" - how long minimum to wait between firing paintarget each time hit
"model2" - .md3 model to also draw
"target" - all entities with a matching targetname will be used when this is destoryed
"health" - default is 10

"luaDie" - Lua-Hook for when the breakable dies

"team" - This cannot take damage from members of this team (2 = blue, 1 = red) 2 will exclude players/clients in RPG-X

Damage: default is none
"splashDamage" - damage to do (will make it explode on death
"splashRadius" - radius for above damage

"material" - sets the chunk type:
 0 - none (default)
 1 - metal
 2 - glass
 3 - glass and metal
 4 - wood
 5 - stone

Don't know if these work:  
"color" - constantLight color
"light" - constantLight radius

q3map2:
"_clone" _clonename of entity to clone brushes from. Note: this entity still needs at least one brush which gets replaced.
"_clonename" see _clone
"_castShadows" OR "_cs" sets whether the entity casts shadows
"_receiveShadows" OR "_rs" sets whether the entity receives shadows

-----LUA-----
Retrofitting repairability using lua:
Retrofitting repairability is possible, however it is not easy as we likely have to come by the fact taht we do not have an origin brush.
To start here is the code with no origin brush present: 
			
	ent = entity.FindBModel(bmodel);  
	ent:SetSpawnflags(ent:GetSpawnflags() + 768);  
	--Do not use entity.CallSpawn(ent); after this point for this entity!
	mover.SetAngles2(ent, posX, posY, posZ);
	ent:SetN00bCount(radius);

The bmodel-number can be retrieved ingame as an admin/developer by pointing at the entity and using the /getentinfo command
posX, Y andf Z are the origin (usually the center of brush) of the entity and need too be retrieved manually from within the radiant
radius is a spherical distance around origin/angles2 that the hyperspanner will respond to. It should barely cover the entire facing side of the entity.

In the unlikely event that we do have an origin brush this is the code:
			
	ent = entity.FindBModel(bmodel);  
	ent:SetSpawnflags(ent:GetSpawnflags() + 256);

/*QUAKED misc_model_breakable (1 0 0) (-16 -16 -16) (16 16 16) SOLID AUTOANIMATE DEADSOLID NO_DMODEL INVINCIBLE X X X REPAIRABLE X
-----DESCRIPTION-----
Destroyable *.md3-model. If it dies it will display it's damge model if one exists and fire it's targets.
If repaired by either target_repair (not yet implemented) or hyperspanner (not yet fully implemented) it will fire it's targets

-----SPAWNFLAGS-----
1: SOLID - Movement is blocked by it, if not set, can still be broken by explosions and shots if it has health
2: AUTOANIMATE - Will cycle it's anim
4: DEADSOLID - Stay solid even when destroyed (in case damage model is rather large).
8: NO_DMODEL - Makes it NOT display a damage model when destroyed, even if one exists. Needs to be set if none exist.
16: INVINCIBLE - Can only be broken by being used
32: X - DO NOT USE! This may come in conflict with shared functions from func_breakable.
64: X - DO NOT USE! This may come in conflict with shared functions from func_breakable.
128: X - DO NOT USE! This may come in conflict with shared functions from func_breakable.
256: REPAIRABLE - can be repaired with hyperspanner
512: X - DO NOT USE! This may come in conflict with shared functions from func_breakable.

-----KEYS-----
"model"	- path to the arbitrary .md3 file to display
"model2" - custom damage model to use. If not set model + _d1 is used for example the damage model for circuit.md3 would be circuit_d1.md3.
"health" - how much health to have - default is zero (not breakable)  If you don't set the SOLID flag, but give it health, it can be shot but will not block NPCs or players from moving
"targetname" - when used, dies and displays damagemodel, if any (if not, removes itself)
"target" - What to use when it dies
"paintarget" - target to fire when hit (but not destroyed)
"wait" - how long minimum to wait between firing paintarget each time hit

"luaDie" - Lua-Hook for when the breakable dies

Damage: default is none
"splashDamage" - damage to do (will make it explode on death)
"splashRadius" - radius for above damage

"team" - This cannot take damage from members of this team (2 = blue, 1 = red) 2 will exclude players/clients in RPG-X

"material" - sets the chunk type:
 0 - none (default)
 1 - metal
 2 - glass
 3 - glass and metal
 4 - wood
 5 - stone

-----LUA-----
Finding an MMB for post-spawn manipulation:
For this purpose we have created a function that will return the first of these that has a matching s.origin.
You can get the s.origin ingame as an admin/developer by pointing at the MMB ingame and using the /getorigin-command.
This is how it should look:

	vec = vector.Construct(s.origin[X], s.origin[Y], s.origin[Z]);
	ent = entity.FindMMB(vec);

Refitting repairablility using lua:
This is a fairly simple addition, here's the code:

	vec = vector.Construct(s.origin[X], s.origin[Y], s.origin[Z]);
	MMB = entity.FindMMB(vec);
	MMB:SetSpawnflags(MMB:
	GetSpawnflags() + 256);
	if MMB:GetHealth() == 0 then --we do require health to be present for repairability
		MMB:SetHealth (1);
		entity.CallSpawn(MMB);
	end
