logic_autosave is a point entity available in all Source games.

Entity description

Logic autosave.png

It is used to force an autosave. It is usually triggered before large firefights or dangerous areas where the player might die.

  • Arguably pointless for multiplayer.

Keyvalues

Force New Level Unit <boolean>
If set, the save will discard any savedata from previous levels, for the purpose of keeping savegame filesizes down. Can only be safely used if there is no way for the player to return to previous levels.
Minimum Hit Points <integer>
Don't save dangerous when player has less than this many hitpoints.
Minimum Hit Points to Commit <integer>
Minimum hitpoints required to commit to save. The save will be made if you have at least Minimum Hit Points, but when the autosave timer expires, the autosave is only kept if you have at least Min Hitpoints to Commit.

Targetname:

Name (targetname) <string>
The targetname that other entities refer to this entity by.
Entity Scripts (vscripts) <scriptlist> (in all games since <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> (in all games since <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.
Note:Try to avoid expensive operations in this function, as it may cause performance problems.

Inputs

Save
Force an autosave.
SaveDangerous <float>
Force an autosave as autosavedangerous.sav. If the player is alive after the passed number of seconds it replaces the standard auto save.
SetMinHitpointsThreshold <integer>
Set MinimumHitPoints to this.

Targetname:

Kill
Removes this entity from the world.
KillHierarchy
Removes this entity and its children from the world.
Note:Entities already remove orphaned children upon being removed, but this input removes all children on the same frame, being marginally faster than Kill.
AddOutput <string>
Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
KV Format: <key> <value>
I/O 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 depending on the entity. Can also be invoked by firing an output that does not specify an input.
RunScriptFile <script> (in all games since <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> (in all games since <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> (in all games since <Left 4 Dead 2>) !FGD
Execute a VScript function in the scope of the receiving entity.
SetLocalOrigin <coordinates> (in all games since <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> (in all games since <Alien Swarm>) !FGD
Set this entity's angles.

Outputs

Targetname:

OnUser1 to OnUser4
These outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.
OnKilled  (only in <Left 4 Dead><Left 4 Dead 2>)
This output fires when the entity is killed and removed from the game.
