English
GMOD中一个投射一个多彩的材质的效果。
Portal 2 将其广泛运用于世界照明。

env_projectedtexture是一个点实体,可用于所有Source游戏以来Half-Life 2: Episode One。 它投射一个材质作为一个动态光源,可以影响这个世界上所有的对象。可选参见Shadow Mapping.

注意:求生之路不起作用(或许某些其他游戏也无效,不过实际有效果),因为valve仅允许一个projectedtexture在地图上,而这一个正好是玩家的手电筒那么hammer放置的此实体被排斥即失败,没有意义。

在源代码中,它由classCEnvProjectedTexture代表,定义在env_projectedtexture.cpp

注意事项

  • Valve's games only support one shadow map in the PVS at a time.
Fix: It is possible to modify/remove this limit by following these instructions.
  • Textures used for projected textures require the flags Clamp S, Clamp T and Clamp All to avoid glitchy tiling. Also note, that VTFs are used directly and no VMT is needed.
Note:In Garry's Mod, there can be up to 9 active env_projectedtextures turned on with shadow mapping at a time. You can also increase this limit by putting -numshadowtextures # in the Steam launch parameters of Garry's Mod, where # is the number of shadow maps the game should allow.
  • Shadows are only rendered when the user is running with "High" shadow detail. If your options menu does not show the "High" shadow detail setting by default, you can add -force_vendor_id 0x10DE -force_device_id 0x1180 to the game's launch options for it to show up.
  • In multiplayer, mat_supportflashlight must be set to 1 for flashlights to work. By default these ConVars are disabled in Team Fortress 2, so this entity won't work there without special configuration.
  • Viewmodels won't receive light or shadows from projected textures. You can follow these instructions to fix this bug.
Bug: In Portal 2, some Nvidia graphics cards render white specks or squares on certain textures. To fix this, remove the bumpmap ($bumpmap or $ssbump) or $detail textures.
Video of said bug.
Bug: Parenting does not work with stock SDK code.
Code Fix: This bug is fixable by following these instructions: Env_projectedtexture/fixes#Fixing Parenting.

Source 2007/2009 bugs

These have all been fixed in more recent engine builds.

Bug: The configurable texture value from Hammer is not accepted - will always default to the flashlight. You must use the SpotlightTexture input or you can also override the actual contents of the default VTF with a new one.
Code Fix: You can fix this issue by following these instructions: Env_projectedtexture/fixes#Fix_configurable_texture_value_in_Hammer.
Note:The SpotlightTexture input has been disabled in the Portal 2 and CS:GO engines, and instead shows an error message: "SetSpotlightTexture is disabled. If you need this feature reimplemented, tell a programmer."
Bug: The entity cannot target another entity.
Code Fix: This bug is fixable by following these instructions: env_projectedtexture/fixes#Fixing targeting.
Bug: Models will not receive their own shadows correctly unless using $bumpmap. Even a flat bump map is sufficient.
Bug: Causes issues if the entity overlaps a portal in Portal 1. Simply the projection overlapping a portal works fine.

Custom Appearance (pattern) <string> (New with Portal 2)
Set a custom pattern of light brightness for this light. Pattern format is a string of characters, where a is total darkness, z fully bright. i.e. aaggnnttzz would be a steppy fade in from dark to light.
Default Appearance (defaultstyle) <string> (New with Portal 2)

Base:

Classname (classname) <string>
The classname defines the type of entity. Classnames can be changed using AddOutput, which will influence how the engine deals with the entity in certain circumstances.
Name (targetname) <string>
The name that other entities refer to this entity by.
Global Entity Name (globalname) <string>
Name by which this entity is linked to another entity in a different map. When the player transitions to a new map, entities in the new map with globalnames matching entities in the previous map will have the previous map's state copied over their state.
Parent (parentname) <targetname>
Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma. Every entity can be parented, even point entities. Entities which are parented will be forced to transition to the next map, such as from a trigger_transition. Some entities which aren't intended to be parented may not function correctly. phys_constraint can be used as a workaround to parenting.
Origin (X Y Z) (origin) <coordinates>
The position of this entity's center in the world. Rotating entities typically rotate around their origin.
Pitch Yaw Roll (X Y Z) (angles) <angle>
This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
Note:This works on brush entities, although Hammer doesn't show the new angles.
Flags (spawnflags) <integer>
Toggles features of an entity, its specific number is determined by the combination of flags added.
Response Contexts (ResponseContext) <string>
Pre-defined response system contexts for this entity. Format is key:value,key:value,.... Contexts may be filtered.
Effects (effects) <integer> !FGD
Combination of effect flags to use.
Local Time (ltime) <float> !FGD
The local time of the entity, independent of the global clock. Used mainly for physics calculations.
Next Think (nextthink) <float> !FGD
Amount of time before the entity thinks again.
Hammer ID (hammerid) <integer> !FGD
The entity's Hammer ID. Mainly used by plugins and debugging commands, such as ent_keyvalue. Can be manually assigned with the "hammerid" or "id" keyvalue. Entities spawned at run-time are not assigned any Hammer ID.
Disable for Xbox 360 (disableX360) <boolean> (New with Left 4 Dead 2) !FGD
If Yes, disables this entity on the Xbox 360 version of Source.
Entity Scripts (vscripts) <scriptlist> (New with Left 4 Dead 2)
Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions.
Script think function (thinkfunction) <string> (New with Left 4 Dead 2)
Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior. The return value (if present) will set the time until the next call. Try to avoid expensive operations in this function, as it may cause performance problems.
Lag Compensation (LagCompensate) <boolean> (New with Left 4 Dead 2) !FGD
Set to Yes to lag compensate this entity. Should be used very sparingly!
Is Automatic-Aim Target (is_autoaim_target) <boolean> (New with Counter-Strike: Global Offensive) !FGD
If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.

Base:

Kill
Removes this entity and any entities parented to it from the world.
KillHierarchy
Functions the same as Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster than Kill.
SetParent  <string>
Move with this entity. See Entity Hierarchy (parenting).
SetParentAttachment  <string>
Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.
SetParentAttachmentMaintainOffset  <string>
As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.
ClearParent
Removes this entity from the the movement hierarchy, leaving it free to move independently.
AddOutput  <string>
Evaluates a keyvalue/output on this entity.
Format: <key> <value>
Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
FireUser1 to FireUser4
Fire the OnUser outputs; see User Inputs and Outputs.
Use  !FGD
Same as a player invoking +use; may not do anything. Can also be invoked by creating an output that does not specify an input.
This input is not included in Valve's FGDs.
DispatchEffect  <string> !FGD
Dispatches a special effect from the entity's origin. Removed and replaced entirely by the particle system since <Left 4 Dead>.
DispatchResponse  <string> !FGD
Dispatches a response to the entity. See Response and Concept.
AddContext  <string>
Adds to the entity's list of response contexts. Format is <key>:<value>.
RemoveContext  <string>
Remove a context from this entity's list. The name should match the key of an existing context.
ClearContext  <string>
Removes all contexts from this entity's list.
RunScriptFile  <script> (New with Left 4 Dead 2)
Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
RunScriptCode  <string> (New with Left 4 Dead 2)
Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console.
Bug:  In <Left 4 Dead 2>, the code is executed in the script scope of the entity that fires the output, not the one receiving the input.
Warning: Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.
CallScriptFunction  <string> (New with Left 4 Dead 2) !FGD
Execute a VScript function in the scope of the receiving entity.
SetLocalOrigin  <coordinates> (New with Alien Swarm) !FGD
Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.
SetLocalAngles  <angles> (New with Alien Swarm) !FGD
Set this entity's angles.

输出

基础:

OnUser1 to OnUser4
这些输出将分别响应于FireUser1 to FireUser4 输入。 详见 User Inputs and Outputs.
