-   * health
-   * gravity
-   * movetype
-   * solid
-   * rendermode
-   * rendercolor (vector)

-   * rename: set entity targetname
-   * settarget: set entity target (only targetnames)
-   * setmodel: set entity model (does not update)
-   * set: set key/value by server library
-       * See game FGD to get list.
-       * command takes two arguments

-   * drop2floor: place entity to nearest floor surface
-   * moveup: move entity to 25 units up
-   * moveup (value): move by y axis relatively to specified value
-* Flags (Set/clear specified flag bit, arg is bit number):
-   * setflag
-   * clearflag
-   * setspawnflag
-   * clearspawnflag
-
-### ent_info
-Print information about entity by identificator
-
-`ent_info <identificator>`
-
-### ent_getvars
-Set client cvars containing entity information (useful for [[Scripting]]) and call ent_last_cb
-
-`ent_getvars <identificator>`
-
-These cvars are set:
-```
-ent_last_name
-ent_last_num
-ent_last_inst
-ent_last_origin
-ent_last_class
-```
-
-### ent_list
-Print short information about antities, filtered by pattern
-
-`ent_list <pattern>`
-
-## Syntax description
-
-### \<identificator\>
-
-* !cross: entity under aim
-* Instance code: !\<number\>_\<seria\l>
- * set by ent_getvars command
-* Entity index
-* targetname pattern
-
-### \<pattern\>
-
-Pattern is like identificator, but may filter many entities by classname
-
-### (vector)
-
-used by ent_fire command. vector means three float values, entered without quotes
-
-### key/value
-
-All entities parameters may be set by specifiing key and value strings.
-
-Originally, this mechanizm is used in map/bsp format, but it can be used in enttools too.
-
-Keys and values are passed to server library and processed by entity keyvalue function, setting edict and entity owns parameters.
-
-If value contains spaces, it must be put in quotes:
-
-`ent_fire !cross set origin "0 0 0"`
-
-## Using with scripting
-
-ent_create and ent_getvars commands are setting cvars on client
-
-It can be used with ent_last_cb alias that is executed after setting cvars.
-
-Simple example:
-
-```
-ent_create weapon_c4
-alias ent_last_cb "ent_fire \$ent_last_inst use"
-```
-
-Use weapon_c4 after creating it.
-
-Note that you cannot use many dfferent callbacks at the same time.
-
-You can set entity name by by pattern and create special script, contatning all callbacks.
-
-Example:
-
-example.cfg
-```
-alias ent_last_cb exec entity_cb.cfg
-ent create \<class\> targetname my_ent1_$name
-ent_create \<class\> targetname my_ent2_$name
-```
-entity_cb.cfg
-```
-if $ent_last_name == my_ent1_$name
-:(ent1 actions)
-if $ent_last_name == my_ent2_$name
-:(ent2 actions)
-```
-Note that scripting cannot be blocking. You cannot wait for server answer and continue. But you can use small scripts, connected with ent_last_cb command. The best usage is user interaction. You can add touch buttons to screen or call user command menu actions by callbacks.
-##  Server side
-
-To enable entity tools on server, set sv_enttools_enable to 1
-
-To change maximum number of entities, touched by ent_fire, change sv_enttools_maxfire to required number.
-
-To enable actions on players, set sv_enttools_players to 1.
-
-To enable entity tools for player by nickname, set sv_enttools_godplayer to nickname. Useful to temporary enable from rcon.
-
-To prevent crash on some actions, set host_mapdesign_fatal to 0

+Set client cvars containing entity information (useful for [scripting](extensions/console-scripting.md)) and then calls ent_last_cb.
+
+`ent_getvars <identificator>`
+
+These cvars are set:
+```
+ent_last_name
+ent_last_num
+ent_last_inst
+ent_last_origin
+ent_last_class
+```
+
+### ent_list
+Print short information about antities, filtered by pattern.
+
+`ent_list <pattern>`
+
+## Syntax description
+
+#### \<identificator\>
+* !cross: entity under aim
+* !\<number\>_\<serial\>: instance code
+* Set by ent_getvars command
+* Entity index
+* Targetname pattern
+
+#### \<pattern\>
+
+Pattern is like identificator, but may filter many entities by classname.
+
+#### (vector)
+
+Used by ent_fire command. vector means three float values, entered without quotes.
+
+#### key/value
+
+All entities parameters may be set by specifiing key and value strings.
+
+Originally, this mechanizm is used in map/bsp format, but it can be used in enttools too.
+
+Keys and values are passed to server library and processed by entity keyvalue function, setting edict and entity owns parameters.
+
+If value contains spaces, it must be put in quotes:
+
+`ent_fire !cross set origin "0 0 0"`
+
+## Using with scripting
+
+ent_create and ent_getvars commands are setting cvars on client
+
+It can be used with ent_last_cb alias that is executed after setting cvars.
+
+Simple example:
+
+```
+ent_create weapon_c4
+alias ent_last_cb "ent_fire \$ent_last_inst use"
+```
+
+Use weapon_c4 after creating it.
+
+Note that you cannot use many different callbacks at the same time.
+
+You can set entity name by by pattern and create special script, contatning all callbacks.
+
+Example:
+
+> example.cfg
+```
+alias ent_last_cb exec entity_cb.cfg
+ent create \<class\> targetname my_ent1_$name
+ent_create \<class\> targetname my_ent2_$name
+```
+> entity_cb.cfg
+```
+if $ent_last_name == my_ent1_$name
+:(ent1 actions)
+if $ent_last_name == my_ent2_$name
+:(ent2 actions)
+```
+Note that scripting cannot be blocking. You cannot wait for server answer and continue. But you can use small scripts, connected with ent_last_cb command. The best usage is user interaction. You can add touch buttons to screen or call user command menu actions by callbacks.
+
+## Server side configuration
+
+To enable entity tools on server, set sv_enttools_enable to 1
+
+To change maximum number of entities, touched by ent_fire, change sv_enttools_maxfire to required number.

+# Support for GoldSrc network protocol
+This feature is still work-in-progress, but for now it's available for all users, and we appreciate any bug-reports and contributions around it.
+
+For connecting to GoldSrc-based servers, use this command:
+```
+connect ip:port gs
+```
+
+But keep in mind, there are requirement for server to be able to accept connections from Xash3D-based clients: it should use Reunion or Dproto.
+Without this requirement, you will just get "Steam validation rejected" error on connecting.
+
+That is because proper authorization with Steam API is not implemented in engine yet (but we have plans on it).
+
+Also, we encountered that some GoldSrc-based servers are recognizing Xash3D clients as "fake clients" and banning/kicking them. Maybe this problem will be
+solved along with better compatibility with GoldSrc behavior, but may be not - we don't know logic behind this fake client checks.

+### HD (external) textures support
+
+Xash3D supports loading texture replacements in TGA format for almost all types of models in the game, except alias models at this time.
+
+Textures are expected to be located at:
+* `modfolder/materials/<mapname>` - for a specific map
+* `modfolder/materials/common` - common for all maps
+* `modfolder/materials/decals` - for decals
+* `modfolder/materials/models/<model>` - for models (texture name must match the internal texture name in the model)
+
+Support for high-resolution textures is enabled setting `host_allow_materials` cvar to `1` or in the menu, in "Video options" section.
+
+#### Xash3D FWGS additions
+
+In addition to paths above, Xash3D FWGS checks following paths:
+
+* `modfolder/materials/sprites/<sprite>` - for sprites, except HUD sprites
+
+Also, to check which texture replacements are loaded successfully, failed or weren't found, a mod developer can set `host_allow_materials` cvar value to `2`. The engine will spew log at any developer level in the following format:
+
+```
+Looking for <replacement> replacement... <status code> (<path relative to mod directory>)
+```
+
+Status codes:
+* `OK` - texture replacement file was found and loaded into GPU memory successfully
+* `FAIL` - texture file was found but hasn't been parsed or loaded successfully. Refer to engine log for more details.
+* `MISS` - texture file wasn't found
+
+Example:
+```
+Looking for maps/bounce.bsp:!waterblue tex replacement...OK (materials/common/!waterblue.tga)
+Looking for maps/bounce.bsp:!waterblue_luma tex replacement...MISS (not found)
+Looking for {shot2 decal replacement...MISS (materials/decals/{shot2.tga)
+Looking for {shot4 decal replacement...MISS (materials/decals/{shot4.tga)
+Looking for {shot3 decal replacement...MISS (materials/decals/{shot3.tga)

+# NAT bypass feature in Xash3D FWGS
+Since IPv6 not as widespread as we would like, NAT (Network Address Translation) still being actively used by many internet service providers in an attempts to
+mitigate IPv4 addresses exhaustion. In short, they uses one IPv4 address and doing some tricks with ports to represent many other users behind this address.
+
+But this leads to a problem for users: they cannot accept direct
+incoming connections anymore. This means that if you are behind provider's NAT and will try to setup Xash3D FWGS server - nobody will be able to connect to it,
+and the server will not show up in servers public list.
+
+## Is it possible to avoid this problem?
+In most cases, it is possible to bypass NAT with UDP hole punching, and Xash3D FWGS uses this method too. But this method is not 100% guaranteed to work - it depends
+on NAT configurations on both server and client side, and there is no way to control it.
+
+First of all, server should not be behind symmetric NAT. You can check your NAT type on [this page](https://www.checkmynat.com/).
+If you get "Symmetric NAT" result in this test, that means you cannot setup publicly available server with internet connection that you are using.
+
+Here is more detailed scheme of different NAT types compatibility, it explains are users with different NAT types can connect to each other or not.
+Client NAT type on rows, server NAT type on columns:
+
+| *NAT Type*           | Full Cone | Restricted Cone | Port Restricted Cone | Symmetric |
+| -------------------- | --------- | --------------- | -------------------- | --------- |
+| Full Cone            | ✔️        | ✔️              | ✔️                    | ✔️        | 
+| Restricted Cone      | ✔️        | ✔️              | ✔️                    | ✔️        |
+| Port Restricted Cone | ✔️        | ✔️              | ✔️                    | ❌        |
+| Symmetric            | ✔️        | ✔️              | ❌                   | ❌        |
+
+## How to use NAT bypass feature?
+If you are starting server within the game, you need to enable option "*Use NAT Bypass instead of direct mode*" in bottom left corner of screen.
+
+If you are starting dedicated server, you should add console variable `sv_nat 1` to server.cfg file, or add `+sv_nat 1` to server startup parameters.
+
+If you need to connect to server behind NAT, there is separate tab named *NAT* for such servers in server browser. Note that it is useless to add NAT server to favorites,
+or somehow trying manually to store it, because it has changing address and port.
