Entity Scripts (vscripts) <scriptlist> Space delimited list of VScript files (without file extension) that are executed after all entities have spawned.

Parent Model Bone/Attachment Name (parentAttachmentName) <string> The name of the bone or attachment to attach to on the entity's parent in the movement hierarchy. Use !bonemerge to use bone-merge style attachment. Model Attachment position offset (local.origin) <coordinates> Offset in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment. Model Attachment angular offset (local.angles) <angles> Angular offset in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment. Model Attachment scale (local.scales) <vector> Scale in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment. Use Model Attachment Offset (useLocalOffset) <boolean> Whether to respect the specified local offset when doing the initial hierarchical attachment to its parent.

Source 2 Transform

Note: These are "Embedded Properties" which are hard-coded to appear on every entity in Hammer, regardless of their presence in any FGD files. Origin (origin) <coordinates> The world space origin of the entity. Angles (angles) <angles> The pitch, yaw, roll orientation of the entity. Scale (scales) <vector> The x, y, z scales of the entity.

Inputs

BeginHack

Begins the hack.

EndHack

EnableDisable:

Enable / Disable <void>

Enable/disable this entity from performing its task. It might also disappear from view.

Source 2 Targetname

Kill Removes this entity from the world. KillHierarchy Removes this entity and all 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 <stringRedirectInput/string> Evaluates a keyvalue/output on 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. RunScriptFile <stringRedirectInput/string> Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity. RunScriptCode <stringRedirectInput/string> 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. CallScriptFunction <stringRedirectInput/string> Execute a VScript function in the scope of the receiving entity. CallPrivateScriptFunction <stringRedirectInput/string> Calls a script function from this entity's private script scope. CallGlobalScriptFunction <stringRedirectInput/string> Calls a script function in the global script scope.

Source 2 Hierarchy

SetParent <stringRedirectInput/string> Changes the entity's parent in the movement hierarchy. SetParentAttachment <stringRedirectInput/string> Change this entity to attach to a specific attachment point on its parent. Entities must be parented before being sent this input. The parameter passed in should be the name of the attachment. SetParentAttachmentMaintainOffset <stringRedirectInput/string> Change this entity to attach to a specific attachment point on it's parent. Entities must be parented before being sent this input. The parameter passed in should be the name of the attachment. The entity will maintain it's position relative to the parent at the time it is attached. ClearParent Removes this entity from the the movement hierarchy, leaving it free to move independently.

Hack Types

Type	Image	Description
Sphere Trace		The player must connect two blue points together by moving one or both, while avoiding red dots. Difficulty determines how many times it must be done, the speed of the red dots and the length of the trails they leave behind.
Point Search		The player must move a central core such that the lasers leading to the core also pass through several points arranged around an area. Difficulty determines the number of connection points and cores needed to align.
Point Match		The player must connect colored pairs of nodes by memory, while also contending with a dividing barrier. Difficulty determines the number of pairs and allowed failures.
Rod Pull		The player must rotate a wedge such that it passes through a small opening in three partial circles. Difficulty has not been implemented on this puzzle. The basic puzzle allows for collisions by adding additional circles to the end of the rod.
Point Drag		The Player must drag a point through several circles while a "fuse" burns down along the same path. Difficulty will reduce the visibility of future circles and increase the fuse speed.
Simple Activate / Toner interact		No puzzle interaction. Basically a variation of a button for electronics.
