func_conveyor

From Valve Developer Community
Jump to: navigation, search

func_conveyor is a brush entity available in all Source Source games. It functions as a conveyor belt, with a moving surface. The surface material should have a ConveyorScroll Material Proxy, to synchronize the material movement and push effect.


In code, it is represented by theCFuncConveyorclass, defined in thebmodels.cppfile.
Icon-Bug.pngBug:Left 4 Dead 2 Does not affect Common infected and witches
Icon-Bug.pngBug:Doesn't effect VPhysics objects, that means that only QPhysics objects (players, walking NPCs, etc.) interact with func_conveyor as as expected. VPhysics objects just stand like on normal surfaces. Fixed in Black Mesa Black Mesa for func_conveyor_bms.

Base:
Collisions (solid) <choices>
Method of collision for this entity.

Values:

Name (targetname) <string>
The name that other entities use to refer to this entity.
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.pngTip:Entities transition to the next map with their parents
Tip.pngTip: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.pngNote: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.pngNote: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.pngTip:Changing this on runtime still has use, like making matching an entry in S_PreserveEnts will persist the entity on new rounds!
Flags (spawnflags) <integer> !FGD
Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.
Effects (effects) <integer> !FGD
Combination of effect flags to use.
Entity Scripts (vscripts) <scriptlist> (in all games since Left 4 Dead 2) (also in Team Fortress 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. Scripts executed on the worldspawn entity will be placed in root scope.
Think function (thinkfunction) <string> (in all games since Left 4 Dead 2) (also in Team Fortress 2)
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 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> (in all games since 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.

EnableDrawInFastReflection  (in all games since Portal 2)
Turn on rendering of this entity in reflections when using $reflectonlymarkedentities in water material.

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 to FireUser4
Fires the respectiveOnUseroutputs; 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 thanKillinput.
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.

RunScriptCode <string> (in all games since Left 4 Dead 2) (also in Team Fortress 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.
Icon-Bug.pngBug:In Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.
Note.pngFix:Remove the string argument manually with a text editor.
Note.pngNote:Team Fortress 2 Backtick characters ` are replaced with quotation marks at runtime, allowing quotation marks to be used when normally not possible.
CallScriptFunction <string> (in all games since Left 4 Dead 2) (also in Team Fortress 2) !FGD
Calls a VScript function defined in the scope of the receiving entity.
TerminateScriptScope  (only in Team Fortress 2) !FGD
