Pit

"Could you just jump into that pit?"
- Wheatley

Bottomless pits are used as obstacles in Portal 2 and destroy objects and players that drop into them, just like grinders and deadly goo. They trigger a fade to black for players that fall into them.

Entities you need

• trigger_hurt - Using the block tool
• player_loadsaved - Using to load to a recent save

Optional:

• trigger_multiple - For destroying objects like prop_weighted_cube

Making the deadly pit

Take your Block tool and make a block, with the trigger texture, in the place where you want the player's death. After that press Ctrl+T and make the it trigger_hurt. You can see many properties but we are only going to use the Damage, Damage cap (only if you have chosen Doubling w/Forgiveness) and the damage type properties.

Change Damage and Damage cap to 1000, and for Damage type to FALL.

Create an entity with Entity tool and change it to player_loadsaved, add a name like "player_loadsaved", then change Fade Duration (seconds) to 1, Hold Fade (seconds) to 5 and Reload Delay to 3, these parameters are used in official maps.

Optionally you can create a brush to destroy objects, simply copy the trigger_hurt and move it down, if you have a fog then move it just enough that you don't see the object getting destroyed, and change the class to trigger_multiple.

Set these flags to checked and the rest to unchecked:

• Pushables
• Physics Objects
• Physics debris

Outputs

Add this output for trigger_hurt:

	My Output >	Target Entity	Target Input	Parameter	Delay	Only Once
	OnStartTouch	player_loadsaved	Reload		0.00	No

Add these outputs for trigger_multiple:

	My Output >	Target Entity	Target Input	Parameter	Delay	Only Once
	OnStartTouch	!activator	SilentDissolve		0.00	No
	OnStartTouch	!activator	Kill		0.10	No

The SilentDissolve input destroys cubes and fires their OnDissolved output correctly, so they can respawn. The Kill output removes other entities that ignore SilentDissolve. It is delayed to ensure SilentDissolve executes first.

If there is no output for SilentDissolve, the player won't able to get a new cube, this could lead to a soft lock in your level.
