/*QUAKED func_plat (0 .5 .8) ?
Rising platform the player can ride to reach higher places. Plats must always be drawn in the raised position, so they will operate and be lighted correctly but they spawn in the lowered position.

It will spawn in the game and work properly but it sounds silly (see Notes).

-------- KEYS --------

lip: lip remaining at end of move (default 16). Has no effect if "height" is set.

height: if set, this will determine the total amount of vertical travel of the plat.

dmg: damage to inflict on player when he blocks operation of plat (default 4). Plat will reverse direction when blocked.

targetname: if set, the trigger that points to this will raise the plat each time it fires. The plat raises and comes back down a second later if no player is on it.

light: constantLight radius of .md3 model included with entity. Has no effect on the entity's brushes (default 0).

_layers OR layers: Integer value is the number unique root shaders that will be use on the terrain.

_shader OR shader: Path to the metashader used to assign textures to the terrain entity. Note: Omit the "textures/" prefix.

-------- NOTES --------
By default, the total amount of vertical travel of a platform is implicitly determined by the overall vertical size of the brushes of which it's made minus the lip value. But if the "height" key is used, then the total amount of vertical travel of the plat will be exactly that value regardless of the shape and size of the plat and regardless of the value of the "lip" key. Using the "height" key is the best method for any kind of platforms and the only possible one for thin plats which need to travel vertical distances many times their own thickness. Setting the origin key is simply an alternate method to using an origin brush. When using the model2 key, the origin point of the model will correspond to the origin point defined by either the origin brush or the origin coordinate value.

There is a way to make plats play proper sounds. Just create a sound\movers\plats folder under baseq3 and put 2 sounds named pt1_strt.wav and pt1_end.wav in it. Those can be the renamed sounds from the Q2 plats or renamed copies of the sound\movers\doors sounds you can extract from your pak0.pk3 file or new custom sounds if you're up to it. Thanks to Fragzilla for the tip.

Target this entity with a misc_model to have the model attached to the entity (set the model's "target" key to the same value as this entity's "targetname").

_remap: Used to remap textures/shaders in the model. To remap all shaders to a given shader, use "*;models/mymodel/mytexture". To remap a specific shader, use "models/mymodel/old;models/mymodel/new".

target: Used to attach the misc_model to a brush entity, where its "targetname" key is the same value.

/*QUAKED misc_light_flare (.65 .65 1) (-8 -8 -8) (8 8 8) SPAWN_DISABLED
A light flare entity.

-------- KEYS --------
targetShaderName: The name of the shader of the light flare.

radius: The radius key is a vector.
The first component is the size of the light flare. The radius is calculated by taking the distance of the viewer from the light flare and dividing by this key, so the larger the key value, the smaller the flare. Values between 2 and 10 are sensible.
The second component indicates the angle around the direction the flare points for which it is visible. For example a value of 90 means that you can see the flare while infront of the entity, but not when behind it. If set to zero the light flare will be visible from any angle
The third component is similar to the first except that it specifies the size of the light source rather than the size of the light flare itself. This is useful when the higher detail flare fading modes are enabled. If this is set to the same value as the first component, fading will commence as soon as the edge of the light flare is occluded by some surface between the viewer and the flare. If it is set larger the flare will overlap the occluding surface before it begins to fade.

angles: This reflects which direction the flare points. It is not important unless the second component of the radius key is employed. angles is a vector of PITCH YAW ROLL. For example a value of "90 0 0" would create a flare pointing down. ROLL is redundant in this context and can be set arbitrarily.

-------- SPAWNFLAGS --------
SPAWN_DISABLED: Spawn disabled.

Triggering this entity toggles it.

target: point this to a target_position entity to set the camera's pointing direction.

targetname: a misc_portal_surface portal surface indicator must point to this.

roll: roll angle of camera. A value of 0 is upside down and 180 is the same as the player's view.

-------- NOTES --------
Both the setting "angles" key or "targeting a target_position" methods can be used to aim the camera. However, the target_position method is simpler. In both cases, the "roll" key must be used to set the roll angle. If either the SLOWROTATE or FASTROTATE spawnflag is set, then the "roll" value is irrelevant.

target: this points to the aiming entity to which the player will jump.

notfree: when set to 1, entity will not spawn in "Free for all" and "Tournament" modes.

notteam: when set to 1, entity will not spawn in "Teamplay" and "CTF" modes.

notsingle: when set to 1, entity will not spawn in Single Player mode (bot play mode).

-------- SPAWNFLAGS --------
BOUNCEPAD: if set, trigger will play bounce noise instead of beep noise when activated (recommended).

-------- NOTES --------
To make a jump pad or launch ramp, create a trigger_multiple where the jump must originate. Place the target_push directly above the trigger_multiple and place the target_position entity at the highest point of the jump. Target the trigger_multiple to the target_push and target the target_push to the target_position/info_notnull (or set the target_push's "angles" key). Note that the "angle" key also works.

/*QUAKED target_speaker (0 .7 .7) (-8 -8 -8) (8 8 8) LOOPED_ON LOOPED_OFF GLOBAL ACTIVATOR
Sound generating entity that plays .wav files. Normal non-looping sounds play each time the target_speaker is triggered. Looping sounds can be set to play by themselves (no activating trigger) or be toggled on/off by a trigger.

-------- KEYS --------
noise: path/name of .wav file to play (eg. sound/world/growl1.wav - see Notes).

wait: delay in seconds between each time the sound is played ("random" key must be set - see Notes).

random: random time variance in seconds added or subtracted from "wait" delay ("wait" key must be set - see Notes).

targetname: the activating button or trigger points to this.

notfree: when set to 1, entity will not spawn in "Free for all" and "Tournament" modes.

notteam: when set to 1, entity will not spawn in "Teamplay" and "CTF" modes.

notsingle: when set to 1, entity will not spawn in Single Player mode (bot play mode).

-------- SPAWNFLAGS --------
LOOPED_ON: sound will loop and initially start on in level (will toggle on/off when triggered).

LOOPED_OFF: sound will loop and initially start off in level (will toggle on/off when triggered).

GLOBAL: sound will play full volume throughout the level.

ACTIVATOR: sound will play only for the player that activated the target.

-------- NOTES --------
The path portion value of the "noise" key can be replaced by the implicit folder character "*" for triggered sounds that belong to a particular player model. For example, if you want to create a "bottomless pit" in which the player screams and dies when he falls into, you would place a trigger_multiple over the floor of the pit and target a target_speaker with it. Then, you would set the "noise" key to "*falling1.wav". The * character means the current player model's sound folder. So if your current player model is Visor, * = sound/player/visor, if your current player model is Sarge, * = sound/player/sarge, etc. This cool feature provides an excellent way to create "player-specific" triggered sounds in your levels.

The combination of the "wait" and "random" keys can be used to play non-looping sounds without requiring an activating trigger but both keys must be used together. The value of the "random" key is used to calculate a minimum and a maximum delay. The final time delay will be a random value anywhere between the minimum and maximum values: (min delay = wait - random) (max delay = wait + random).

humanBuildPoints: The maximum amount of power the humans can use. Defaults to 1000.

humanMaxStage: The highest stage the humans are allowed to use [0/1/2]. Defaults to 2.
humanStage2Threshold: The number of kills the humans must aquire to advance to stage 2. Defaults to 50.
humanStage3Threshold: The number of kills the humans must aquire to advance to stage 3. Defaults to 100.

alienBuildPoints: The maximum amount of sentience available to the overmind. Defaults to 1000.

alienMaxStage: The highest stage the aliens are allowed to use [0/1/2]. Defaults to 2.

disabledEquipment: A comma delimited list of human weapons or upgrades to disable for this map.
disabledClasses: A comma delimited list of alien classes to disable for this map.
disabledBuildables: A comma delimited list of buildables to disable for this map.

_ambient OR ambient: Adds a constant value to overall lighting. Use is not recommended. Ambient light will have a tendency to flatten out variations in light and shade.

_color: RGB value for ambient light color (default is 0 0 0).

gravity: gravity of level (default is normal gravity: 800).

gridsize: granularity of the lightgrid created by q3map. Value is three integers separated by spaces, representing number of units between grid points in X Y Z. Default gridsize value is 128 128 256. Use larger powers of 2 to reduce BSP size and compile time on very large maps.

_blocksize: q3map always splits the BSP tree along the planes X=_blocksize*n and Y=_blocksize*n. Default _blocksize value is 1024. Increase the blocksize using larger powers of 2 to reduce compile times on very large maps with a low structural brush density.

-------- Q3MAP2 KEYS --------
_minlight: Minimum light value, levelwide. Uses the _color key to set color. Does not add unlike ambient.

_minvertexlight: Minimum vertex lighting, levelwide.

_mingridlight: Minimum lightgrid (dynamic entity lighting) levelwide.

_keeplights: Keep light entities in the BSP. Normally stripped out by the BSP process and read from the .map file by the lighting phase.

_noshadersun: Ignore q3map_sun/sun directives in sky shaders and ONLY use entity sun lights.

_farplanedist: Limit on how many units the vis phase of compilation can see. Used in combination with level-wide fog, it can help reduce r_speeds on large, open maps.

_foghull: Shader to use for "fog hull." Foghull shader should be a sky shader. Omit the "textures/" prefix.

_lightmapscale: Floating point value scaling the resolution of lightmaps on brushes/patches in the world. Can be overridden in func_group (or other entities) (default 1.0).

_cs OR _castshadows: Allows per-entity control over shadow casting. Defaults to 0 on entities, 1 on world. 0 = no shadow casting. 1 = cast shadows on world. > 1 = cast shadows on entities with _rs (or _receiveshadows) with the corresponding value, AND world. Negative values imply same, but DO NOT cast shadows on world.

_rs OR _receiveshadows: Allows per-entity control over shadow reception. Defaults to 1 on everything (world shadows). 0 = receives NO shadows. > 1 = receive shadows only from corresponding keyed entities (see above) and world. < 1 = receive shadows ONLY from corresponding keyed entities.

_celshader: Sets the cel shader used for this geometry. Note: omit the "textures/" prefix. Overridable in entities.

-------- Q3MAP2 TERRAIN KEYS --------
_indexmap OR alphamap: Path/name for the art file used to guide the mapping of textures on the terrain surface.

_layers OR layers: Integer value is the number unique root shaders that will be use on the terrain.

_shader OR shader: Path to the metashader used to assign textures to the terrain entity. Note: Omit the "textures/" prefix.
