trigger_fall_catch

Sven Co-op point entity. Catches players that fall below a reference point: fires a target and/or respawns them.

Install

1. Copy fall_catch.as to scripts/maps/.
2. In the map .cfg add map_script <path without extension>.
3. Add fall_catch.fgd to your Hammer game configuration.

How it works

Every scantime seconds each alive player is checked. A player is fallen when feet.z < reference.z + offset, where feet.z = origin.z + mins.z. The reference is the watch entity, otherwise the trigger itself.

For a fallen player: target is fired (the player is the activator), then the player is respawned if the flag is set, then the sound plays. After that the player is ignored for cooldown seconds.

Keys

Key	Default	Description
targetname		Needed to turn the entity On/Off with Use.
initial_state	1	State at map start: 0 Off, 1 On.
target		Fired with the fallen player as activator. A delay in between replaces the activator.
watch		Entity used as the reference point instead of this one, for example a train. Brushes use their center.
offset	-8	Added to the reference Z. A player is fallen when their feet are below the result. Use a negative value.
radius	0	Horizontal radius around the reference. Players farther away are ignored. 0 = unlimited.
cooldown	0.5	Seconds before the same player can be caught again. Without it a player still below the line would trigger on every check.
scantime	0.1	Seconds between checks. Lower = faster reaction, more load. Below 0.01 falls back to 0.1.
sound		Path relative to sound/. Empty = no sound. Custom sounds must be in the map .res.
health	10	Sound volume, 1-10. 0 or unset = 10.
pitch	100	Sound pitch, 1-255. Above 100 = higher.

Flags

Value	Name	Effect
1	Respawn Player	Respawn the player on an active spawn point.
2	Debug Log	Print [fall_catch] diagnostics to the console.

On enables, Off disables, anything else toggles.

Notes

• Z-only check, meant for flat floors. On a slope a player can end up below the reference and gets caught.
• Respawn Player does not move spawn points. For a train or platform the spawn point has to follow it, for example with trigger_setorigin.
• Players only. Noclip players are not excluded.
• The sound is meant to be heard only by the fallen player (target_ent_unreliable). Not verified in-game.
