ai_goal_assault
ai_goal_assault
is a point entity available in all Source games.
This entity specifies which NPCs are to carry out an assault, and triggers it when any conditions given are met. One goal can handle multiple rally points. Must be active to be able to be triggered.
Upon activation, the entity will round up all its actors (specified in a keyvalue), and instruct them to select their assault_rallypoint
(s) and move to it/them. Upon arrival at the rally point(s), each actor then begins waiting for an Assault Cue, unless instructed to assault immediately.
Upon the cue, it will then instruct all actors to begin moving on from their current rally point to the assault_assaultpoint
specified by the rally point.

Keyvalues
- Rally Point Set (rallypoint)
(???)
<targetname> - The name of the
assault_rallypoint
(s) at which this assault will begin. This field can also support wildcards, so that you can enter the root name of all rally points for this assault followed by an asterisk '*', to match all with the same root.
- Assault Cue (AssaultCue)
(???)
<choices> - Chooses when the goal is going to be set after this entity has been activated.
- 1: Entity System Input (
BeginAssault
) - 2: Gunfire (When the entity 'hears' gunfire Todo: Tested with player weapons and ai_sound, no results.
- 1: Entity System Input (
)
- 3: Don't wait for a cue. (Attack immediately after rallying finishes)
- Rally Point Selection Method (RallySelectMethod)
(???)
<choices> - How NPCs will decide which rallypoint to move to.
- For games before Alien Swarm (including 2013 SDK):
- 0: Choose by priority. If there are multiple tied for priority, go to the closest one.
- 1: Choose randomly
- 2: If priority is tied, go to the point farthest away.
- Branch Method (BranchMethod)
(???)
<integer> (in all games since ) !FGD - Confirm:Default (0) tells NPCs to pick randomly if they come across multiple
assault_assaultpoint
s they can use. 1 makes NPCs pick whichever is closest to them.
AI_GoalEntity:
- Actor(s) to affect
(actor)
<target_name_or_class> - The targetname or classname of any NPCs that will be included in this goal. Wildcards are supported.
- Search Type
(SearchType)
<choices> - What the Actor(s) to affect keyvalue targets by.
- 0: Entity Name
- 1: Classname
- Start Active
(StartActive)
<boolean> - Set if goal should be active immediately.
Base:
- Parent
(parentname)
<targetname> - Maintain the same initial offset to this entity. An attachment point can also be used if separated by a comma at the end. (
parentname [targetname],[attachment]
)Tip:Entities transition to the next map with their parentsTip:phys_constraint
can be used as a workaround if parenting fails.
- Origin (X Y Z)
(origin)
<coordinates> - The position of this entity's center in the world. Rotating entities typically rotate around their origin.Note:Hammer does not move the entities accordingly only in the editor.
- 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.
- Classname
(classname)
<string> !FGD - Determines the characteristics of the entity before it spawns. Tip:Changing this on runtime still has use, like making matching an entry in S_PreserveEnts will persist the entity on new rounds!
- Spawnflags
(spawnflags)
<flags> !FGD - Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.
- Effects
(effects)
<flags> !FGD - Combination of effect flags to use.
- Entity Scripts
(vscripts)
<scriptlist> (in all games since ) (also in ) - 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. Scripts executed on the worldspawn entity will be placed in root scope.
- Think function
(thinkfunction)
<string> (in all games since ) (also in ) - Name of the function within this entity's script that'll be called automatically every 100 milliseconds, or a user-defined interval if the function returns a number. Avoid expensive operations in this function, as it may cause performance problems.
- Lag Compensation
(LagCompensate)
<boolean> (in all games since ) !FGD - Set to Yes to lag compensate this entity. Should be used very sparingly!
- Is Automatic-Aim Target
(is_autoaim_target)
<boolean> (in all games since ) !FGD - If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.
Inputs
BeginAssault
- If the entity is active and this entity's Assault Cue keyvalue is set to Entity System Input, begin the assault. Tip:This will cause NPCs to "skip over" the rally point if they aren't there already. Useful for using rally points for selecting actors.
AI_GoalEntity:
Activate
- Make the goal active if it wasn't already. NPCs will begin taking orders.
Deactivate
- Make goal inactive.
UpdateActors
!FGD- Tell the goal entity to re-check Actor(s) to affect in case any disappeared, or any new NPCs spawned.[confirm]
Base:
AddContext
<string>- Adds to the entity's list of response contexts. See Context.
AddOutput
<string>- Assigns a new keyvalue/output on this entity. For keyvalues, some rely on extra necessary code to be ran and won't work if its simply just changed through this input. There is a strict format that must be followed:
// Format of changing KeyValues: "AddOutput [key] [value]"
//// Raw text:
"OnUser1" "!self,AddOutput,targetname new_name"
// Format of adding an Output: "AddOutput {targetname}:{inputname}:{parameter}:{delay}:{max times to fire, -1 means infinite}"
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:SetParent:!activator:0.0:-1"
// Arguments can be left blank, but the empty blank should still be contained.
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:ClearParent::0.0:-1"
|
ClearContext
- Removes all contexts from this entity's list.
ClearParent
- Removes this entity from the the movement hierarchy, leaving it free to move independently.
FireUser1
toFireUser4
- Fires the respective
OnUser
outputs; see User Inputs and Outputs.
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 thanKill
input.
RemoveContext
<string>- Remove a context from this entity's list. The name should match the key of an existing context.
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.
DispatchResponse
<string> !FGD- Dispatches a response to the entity. See Response and Concept.
DispatchEffect
<string> (removed since ) !FGD- Dispatches a special effect from the entity's origin; See also List of Client Effects. Replaced by the particle system since .
RunScriptFile
<script> (in all games since ) (also in )- 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 ) (also in )- 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 Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.Fix:Remove the string argument manually with a text editor.
CallScriptFunction
<string> (in all games since ) (also in ) !FGD- Calls a VScript function defined in the scope of the receiving entity.
TerminateScriptScope
(only in ) !FGD- Destroys the script scope of the receving entity.
SetLocalOrigin
<coordinates> (in all games since ) !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.
Outputs
Base:
OnUser1
toOnUser4
- These outputs each fire in response to the firing of the like-numbered
FireUser1
toFireUser4
Input; see User Inputs and Outputs.
