HOW TO BUILD A FIRE TRAP
DESCRIPTION
In the HL2 Ravenholm scene, you most likely encountered the fire trap obstacle.
To advance into the main building without taking damage from the fire; you discovered that you could extinguish the fire by turning the propane tank's valve off. Then, you may have cleverly deduced that you could draw out the zombies and re-ignite the fire, as they ambled through the trap zone. (Loads of fun!)
This page will describe the steps to build a fire trap from scratch, for use in your custom map.
FIRE TRAP SYSTEM DESCRIPTION
The fire-trap system is comprised of a set of smaller functioning components which, when triggered in a logical order of sequence, will invoke a controlled fire. If we were to build this in the real world, we would probably want to examine what the system is comprised of:
A Combustable Fuel Source:
- In this case, propane gas is a viable option.
A Fuel-Source Deleivery System:
- A Propane-Gas tank for storage of the gas
- A plunger (wheel-valve) to release the gas
- Some pipes to strategically channel the released gas. (Preferably with gas-jet nozzles).
A Fuel Igniter System:
- A pizzo-electric triggered spark via a push-button.
An Extinguisher System:
- The wheel-valve, as describe above.
