This wall of particles destroys any objects that come in contact with it and closes any portals that have been opened by the player.
 
=== Step 1 ===
 
Due to the sheer size of the fizzler you may need to create an appropriate sized doorway to construct the fizzler in.
 
Use the portal_cleanser and cleanser_edge_1 particle effects. cleanser_edge_1 is best used for cleansers wider than 192 units.
 
=== Step 2 ===
The first thing that needs to be created is the doorway that will act as the fizzler holder. You can also use a prop for this effect as well, however for the purpose of this tutorial a model will be used.
 
{{Note|You can make a fizzler any size you want for your map, it will just require more [[info_particle_system]] entities.}}
 
The available props for this is:
* '''models/props/portal_cleanser_1.mdl'''
To use as a base we need to create a [[trigger_portal_cleanser]], which in size should be ''128x128''. Note that this is the base size for a '''normal sized''' fizzler. Also the trigger should be just '''2''' Units thick.
 
Go ahead and name it if you want, that way you can keep track of how many you might have.

Modify the following flags:
 
{{entity-flag-start}}
{{entity-flag|Everything|on|}}
{{entity-flag-end}}
 
{{note|If your fizzler models are a prop_dynamic, they will dissolve if the Everything flag is on, you can enable the <code>Physics Objects</code> Flag as an alternative}}
 
=== Step 3 ===
[[File:Fizzler framer&trigger.jpg|200px|thumb|right|framer&trigger]]
Make 2 [[prop_static]] entities and set their World Model to '''models/props/portal_cleanser_1.mdl''', rotate one of them by 180 degrees.
 
You are free to line up everything you have so far directly in a straight line, or you can change it to your liking.

=== Step 4 ===
[[File:Hindding particles.jpg|250px|thumb|right|two [[info_particle_system]] in model]]
Create a [[info_particle_system]] entity and enter the following properties:
 
{| class=standard-table
!  Property Name || Value
|-
| Particle System Name || portal_cleanser
|-
| Start Active || Yes
|}
 
Align it to the trigger brush precisely in the center.

=== Respawning Boxes ===
 
If you have a box dropper that you want to spawn a new box if the player destroys one with a fizzler, you can use the output ''OnDissolveBox'', but only if your box prop_physics is named '''box'''.
 
If you have multiple droppers in your map along with a cleanser and you want the box dropper to deliver a new box, follow these instructions:
 
Enter this output for the '''trigger_portal_cleanser''':
{| {{OutputsTable}}
| [[File:Io11.png]] || OnDissolve || !activator || FireUser1 || <none> || 0.00 || No
|}
 
Enter this output for the '''box''':
{| {{OutputsTable}}
| [[File:Io11.png]] || OnUser1 || logic_drop_box || Trigger || <none> || 0.00 || No
|}
 
You will have to change the logic_drop_box name in the output depending on which box dropper the box came from.
