Hi, if you mean making it as part of your map you can do 2 things:
1. Spawn a prop_physics using the entities tools and change the world model to something made of wood like a crate.
2. Make a brush face (a normal solid block, using the block tool) and press "Ctrl + T" or click tools, tie to entity and select func_breakable then choose the settings you want.
The only in game editors for portal are these 2 which I can think of: 1.garrys mod (not really much of a game EDITOR) 2.Valve's hammer editor, where you can create your own levels for more or less every game on steam (although im not sure and its very complicated)
In Valve Hammer Editor, you can view the selected face texture by selecting the face in the 3D view and then checking the "Texture Application" window. This window displays the current texture applied to the selected face, allowing you to see its properties and make any adjustments as needed. Additionally, you can use the "Texture Browser" to browse and apply different textures to your selected face. To preview the texture in the 3D view, you can also toggle the texture display mode.
Source SDK's Hammer editor is used to make all valve produced games such as CS:S, HL2, Team Fortress, L4D and more Go to www.devloper.valvesoftware.com
To get Hammer tutorials for Portal 2, you can start by downloading the Source SDK through Steam, which includes the Hammer Editor. Look for video tutorials on platforms like YouTube or check community forums and websites like the Steam Community or ModDB for guides. Additionally, the Valve Developer Community wiki offers detailed information and resources specific to creating maps for Portal 2.
A hammer arrester valve in a plumbing system is used to prevent water hammer, which is a loud banging noise that occurs when water flow is suddenly stopped. The valve absorbs the shock caused by the sudden stoppage of water flow, protecting the pipes and fixtures in the plumbing system from damage.
When a valve is closed quickly the flow of water is interupted causing a water hammer. A water hammer arrestor or air chamber can be used to absorb the hammer.
Water hammer in a toilet is often caused by high water pressure or a malfunctioning fill valve. To solve this issue, you can try adjusting the water pressure, installing a water hammer arrestor, or replacing the fill valve.
Any quick closing valve such as a solenoid can cause hydraulic shock waves
Spray wd40 or equal and tap valve "gently" with a hammer while "gently" appling turn pressure on valve.
To release air that cause water hammer
sudden stopages of flow by the closure of a valve
Through the spark plug hole, soak the valve with penetrating oil. After sitting a while, tap lightly on the valve stem with a hammer. If after several tries this does not work then the head will need to be removed to see why the valve is stuck.
