func_smokevolume is a brush entity available in all Source games.
Warning: Smoke volumes should be used sparingly as they can decrease performance in heavily detailed scenes, or scenes with high amounts of action. Particle systems may be cheaper to use, depending on CPU usage restraints.
Warning: Smoke volumes shouldn't be placed in the same volume as func_precipitation is. Otherwise engine may freeze at the end of loading the level. It is probably caused by some particle coding that do not accept this two types of sprites to render at once (in the same volume).
particle/smoke_grenade1, which does not exist. However,
- Particle Color1 (R G B)
- How dim particles can be.
- Particle Color2 (R G B)
- How bright particles can be.
- The material to use for the particles
- Particle Draw Width (units)
- The size of the particles, in units/inches. (Typical Values: 128,175,200,500,512)
- Particle Spacing Distance (units)
- The distance between the particles inside the volume. The lower the number, the denser the particles, and the more overdraw there will be. It is best to keep it as high as you can without it looking bad. (Typical Values: 125,150,200 and sometimes 80 or 480)
- Density Ramp Speed (seconds)
- Time to go from density 0 to density 1, in seconds.
- Rotation Speed (degrees/sec)
- The speed that the particles should rotate, in degrees per second. (Typical Values: 3,10)
- Movement Speed (units/sec)
- The speed that the particles should move around, in units/inches per second.
- Density [0..1]
- Particle density, from 0 to 1. (Typical Values: .1-.5)
- Entity Scripts
- 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
- 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.
- 1 : Emissive
- Makes sprites render fullbright. Normally the brightness is affected by light nearby.
- Set the particle rotation speed (in degrees per second).
- Set the particle movement speed (in inches per second).
- Set the particle density. It should be a range from 0 to 1.
- Removes this entity from the world.
- 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
- Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
<output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
- Fire the
OnUseroutputs; see User Inputs and Outputs.
- 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.
- Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
- 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 , 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.
- Execute a VScript function in the scope of the receiving entity.
- 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.
- Set this entity's angles.
- These outputs each fire in response to the firing of the like-numbered
FireUser4Input; see User Inputs and Outputs.
- This output fires when the entity is killed and removed from the game.
