Making a Real FenceThis would allow bullets to pass and block players going through.
You might have noticed that in some areas in Half-Life, there are fences that the player can shoot through. It's a simple idea, but it requires a little trick to set up.
You will notice that some entities, including the monster_generic ones that are in the example map as holograms, have a flag called Not Solid that allows you to let the player to walk through them. This has obvious uses, such as... well... for making a hologram. But it won't work for fences, because, firstly, func_wall entites don't have a Not Solid flag, and even if they did, the player would be able to move though as well as bullets. But there is a way round this problem.
It just so happens that func_illusionary was designed to be, um, illusionary, so it's basically a non-solid func_wall, and can be made to display masked textures in the same way as a normal func_wall. Then, to stop the player moving though, you can simply create a 'clip' brush - Select the texture called 'clip', and create a brush. This stops the player moving through, but not bullets... and not monsters. To stop the monsters, create another brush with some texture other than 'clip', and bind it to a func_monsterclip entity. Place all three brushes over each other, and you have a 'real' fence!
