These are the root sound operators referenced in Portal 2. See scripts/sound_operator_stacks.txt and Soundscripts#Sound operators for more details.
Common properties
execute_once- Whether the operator should run every time the stack is evaluated, or only the first time. Output values are presumable stored between executions in the latter case.
input_execute- The operator will only run if this value is true (i.e. non-zero).
import_stack- Inserts another named stack into this one.
Operator list
System
Affect sound playback.
sys_stop_entries- Stops sounds from playing.
match_channel- Sound must have the same channel (e.g. CHAN_STATIC) to match
match_entity- Sound must be coming from the same entity as this one
match_entry- The sound entry name to look for
match_substring- Whether
match_entrycan be part of a larger string (e.g. "MyGun" matches MyGun.fire, MyGun.reload...). input_max_entries
Confirm:The number of times this sound can be playing at once?
- sys_start_entry
- sys_block_entries
- sys_output
- sys_platform
- sys_mixlayer
Maths
Generate or process numbers.
math_random- Produces a random number. Access it with
@MyRandom.output.input_mininput_max- Range of values to output.
- math_float
- math_delta
- math_remap_float
- math_func1
Getters
Provide values from the engine.
- get_entry_time
- get_sys_time
- get_source_info
- get_soundmixer
- get_convar
- get_dashboard
- get_map_name
Calculations
Calculate pre-set algorithms.
- calc_angles_facing
- calc_distant_dsp
- calc_occlusion
- calc_falloff
- calc_source_distance
- calc_spatialize_speakers
Other
