Chicken Sandwich

I just learned how to add custom textures to a wad, but i havent seen anything on custom switches. I searched through a heap of tutorial lists and forum posts but cant find anything telling you how to do this. Can someone please provide a link to a tutorial or post here on how to achieve this? Preferably in SLADE3 Note: Not looking to replace existing switches in the game.

Thanks guys that helped alot! Just now i have found this guy on youtube. I dont think english is his first language but he seems alright.

I wish to have standard ammo capacity at the normal amount. keep back pack capacity normal. but then have a second kind of backpack that increases it further and this is what i dont know how to do. I have looked at zdoom wiki's backpack decorate but it says nothing about max ammo capacity. any help is greatly appreciated :)

Thankyou R4L :) Even with all my searches that one still slipped by somehow..

I am using Gzdoom to make my maps, and i have come to a point where i want to make the maximum health pass 200%. How would i go about doing this?

Looks killer. Is all this meant to be played in single player?

im using gzdoom builder atm and im getting a glitch where i go to operate the door as normal, and it goes down one step then back to its original position. ive made countless doors and never encountered this but for some reason these 2 doors just do this. only been building for a month now tho. i read what was said here, so i made the ceilings in the sectors beside the door even with the roof again, then raised the floor to the ceiling instead. operated the door and it worked like a dream. i dont know the technical behind it but it would be good to know if anyone can be bothered explaining.
