START_OPEN the door to moves to its destination when spawned, and operate in reverse. It is used to temporarily or permanently close off an area when triggered (not useful for touch or takedamage doors).
FORCE_ACTIVATE Can only be activated by a force push or pull
CRUSHER ?
TOGGLE wait in both the start and end states for a trigger event - does NOT work on Trek doors.
LOCKED Starts locked, with the shader animmap at the first frame and inactive. Once used, the animmap changes to the second frame and the door operates normally. Note that you cannot use the door again after this.
PLAYER_USE Player can use it with the use button
INACTIVE must be used by a target_activate before it can be used
"target" Door fires this when it starts moving from it's closed position to its open position.
"opentarget" Door fires this after reaching its "open" position
"target2" Door fires this when it starts moving from it's open position to its closed position.
"closetarget" Door fires this after reaching its "closed" position
"model2" .md3 model to also draw
"angle" determines the opening direction
"targetname" if set, no touch field will be spawned and a remote button or trigger field activates the door.
"speed" movement speed (100 default)
"wait" wait before returning (3 default, -1 = never return)
"delay" when used, how many seconds to wait before moving - default is none
"lip" lip remaining at end of move (8 default)
"dmg" damage to inflict when blocked (2 default, set to negative for no damage)
"color" constantLight color
"light" constantLight radius
"health" if set, the door must be shot open
"linear" set to 1 and it will move linearly rather than with acceleration (default is 0)
"teamallow" even if locked, this team can always open and close it just by walking up to it
0 - none (locked to everyone)
1 - red
2 - blue

RADAR - shows up on Radar in Siege mode (good for asteroids when you're in a ship)
IMPACT - Kills anything on impact when rotating (10000 points of damage, unless specified otherwise)
You need to have an origin brush as part of this entity. The center of that brush will be
the point around which it is rotated. It will rotate around the Z axis by default. You can
check either the X_AXIS or Y_AXIS box to change that.
"model2" .md3 model to also draw
"model2scale" percent of normal scale (on all x y and z axes) to scale the model2 if there is one. 100 is normal scale, min is 1 (100 times smaller than normal), max is 1000 (ten times normal).
"speed" determines how fast it moves; default value is 100.
"dmg" damage to inflict when blocked (2 default)
"color" constantLight color
"light" constantLight radius
"spinangles" instead of using "speed", you can set use this to set rotation on all 3 axes (pitch yaw and roll)
==================================================
"health" default is 0
If health is set, the following key/values are available:
"numchunks" Multiplies the number of chunks spawned. Chunk code tries to pick a good volume of chunks, but you can alter this to scale the number of spawned chunks. (default 1) (.5) is half as many chunks, (2) is twice as many chunks
"chunksize" scales up/down the chunk size by this number (default is 1)
"showhealth" if non-0, will display the health bar on the hud when the crosshair is over this ent (in siege)
"teamowner" in siege this will specify which team this thing is "owned" by. To that team the crosshair will
highlight green, to the other team it will highlight red.
Damage: default is none
"splashDamage" - damage to do
"splashRadius" - radius for above damage
"team" - If set, only this team can trip this trigger
0 - any
1 - red
2 - blue
Don't know if these work:
"color" constantLight color
"light" constantLight radius
"material" - default is "0 - MAT_METAL" - choose from this list:
0 = MAT_METAL (basic blue-grey scorched-DEFAULT)
1 = MAT_GLASS
2 = MAT_ELECTRICAL (sparks only)
3 = MAT_ELEC_METAL (METAL2 chunks and sparks)
4 = MAT_DRK_STONE (brown stone chunks)
5 = MAT_LT_STONE (tan stone chunks)
6 = MAT_GLASS_METAL (glass and METAL2 chunks)
7 = MAT_METAL2 (electronic type of metal)
8 = MAT_NONE (no chunks)
9 = MAT_GREY_STONE (grey colored stone)
10 = MAT_METAL3 (METAL and METAL2 chunk combo)
11 = MAT_CRATE1 (yellow multi-colored crate chunks)
12 = MAT_GRATE1 (grate chunks--looks horrible right now)
13 = MAT_ROPE (for yavin_trial, no chunks, just wispy bits )

/*QUAKED func_breakable (0 .8 .5) ? INVINCIBLE IMPACT CRUSHER THIN SABERONLY HEAVY_WEAP USE_NOT_BREAK PLAYER_USE NO_EXPLOSION
INVINCIBLE - can only be broken by being used
IMPACT - does damage on impact
CRUSHER - won't reverse movement when hit an obstacle
THIN - can be broken by impact damage, like glass
SABERONLY - only takes damage from sabers
HEAVY_WEAP - only takes damage by a heavy weapon, like an emplaced gun or AT-ST gun.
USE_NOT_BREAK - Using it doesn't make it break, still can be destroyed by damage
PLAYER_USE - Player can use it with the use button
NO_EXPLOSION - Does not play an explosion effect, though will still create chunks if specified
When destroyed, fires it's trigger and chunks and plays sound "noise" or sound for type if no noise specified
"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
"delay" When killed or used, how long (in seconds) to wait before blowing up (none by default)
"model2" .md3 model to also draw
"target" all entities with a matching targetname will be used when this is destoryed
"health" default is 10
"numchunks" Multiplies the number of chunks spawned. Chunk code tries to pick a good volume of chunks, but you can alter this to scale the number of spawned chunks. (default 1) (.5) is half as many chunks, (2) is twice as many chunks
"chunksize" scales up/down the chunk size by this number (default is 1)
"playfx" path of effect to play on death
"showhealth" if non-0, will display the health bar on the hud when the crosshair is over this ent (in siege)
"teamowner" in siege this will specify which team this thing is "owned" by. To that team the crosshair will
highlight green, to the other team it will highlight red.
Damage: default is none
"splashDamage" - damage to do
"splashRadius" - radius for above damage
"team" - If set, only this team can trip this trigger
0 - any
1 - red
2 - blue
Don't know if these work:
"color" constantLight color
"light" constantLight radius
"material" - default is "0 - MAT_METAL" - choose from this list:
0 = MAT_METAL (basic blue-grey scorched-DEFAULT)
1 = MAT_GLASS
2 = MAT_ELECTRICAL (sparks only)
3 = MAT_ELEC_METAL (METAL2 chunks and sparks)
4 = MAT_DRK_STONE (brown stone chunks)
5 = MAT_LT_STONE (tan stone chunks)
6 = MAT_GLASS_METAL (glass and METAL2 chunks)
7 = MAT_METAL2 (electronic type of metal)
8 = MAT_NONE (no chunks)
9 = MAT_GREY_STONE (grey colored stone)
10 = MAT_METAL3 (METAL and METAL2 chunk combo)
11 = MAT_CRATE1 (yellow multi-colored crate chunks)
12 = MAT_GRATE1 (grate chunks--looks horrible right now)
13 = MAT_ROPE (for yavin_trial, no chunks, just wispy bits )
14 = MAT_CRATE2 (red multi-colored crate chunks)
15 = MAT_WHITE_METAL (white angular chunks for Stu, NS_hideout )
16 = MAT_SNOWY_ROCK (mix of gray and brown rocks)
Applicable only during Siege gametype:
teamnodmg - if 1, team 1 can't damage this. If 2, team 2 can't damage this.
