Creating a ladder that our character can climb to escape from the zombies for just a few seconds is simple. Watch the video to find out how and check out the notes.
1. Place prop_static entity where you want your ladder to go. This will be the ladder you will climb. This is not a ladder you can actually climb yet.
If you don't know how to add a prop_static into your map, see Adding Props Tutorial.
2. Create a brush with 'nodraw' texture on it. Position it in front of the ladder and make sure it is 2 units in depth.
3. Apply 'Ladder' texture to the front of the brush face.
4. Select your newly created ladder brush and press Cntrl+T or click toEntity.
