For this tutorial I could have used just about anything for our electrified obstacle but picked this small railing because the player can jump over it once the electricity is turned off.
In this tutorial, we will create an obstacle in which it is electrified and can be toggled by a [[trigger]]. You can any [[model]] for this, but for the tutorial we will use a railing from ''Half Life 2'' (see right).  
Of course we could apply this same method to a ladder, door/gate or even water/ground.


In this example the railing is initially electrified but can be disabled by standing on the small Red carpet. Standing on the small Green carpet will re-enable the electricity. (The carpets are not shown here)

When a player "touches" the fence while it is electrified there will be sparks, smoke and sounds plus the player will get blown back a few feet.

The [[trigger_hurt]] used in this tutorial starts off a series of events when the player touches it.

Once the player touches the [[trigger_hurt]] these entities are excited to get going via outputs:

I don’t think you need a step by step on creating this.

Electrified Obstacles

Typical electrified obstacle.

In this tutorial, we will create an obstacle in which it is electrified and can be toggled by a trigger. You can any model for this, but for the tutorial we will use a railing from Half Life 2 (see right).

Note.pngNote:Remember the player has to get around the obstacle.
Note.pngNote:You could apply this concept to a ladder, door/gate or even water/ground.


For the purpose of this tutorial the rail obstacle is initially electrified, however, it can be disabled by standing on a small red carpet and re-enabled by standing on a small green carpet (the carpets are not shown in screenshots).

When a player "touches" the fence while it is electrified there will be sparks, and the player will get blown back a few feet.

Hammer design view.

In the tutorial, the prop_static entity is for the railing/electrified object but you could just as easily use motion enabled entity types.


Tip.pngIdea:This concept could be extended to a gate that would swing open once the electricity was turned off, or even a loose cable trapped under a vehicle.

Wrap up

There’s a lot more you can do, hopefully this article have stimulated your imagination.
