Making a switch

Swithces can do alot of things but in vanilla doom they are a tad limited but can still be great for maps firstly follow the normal door tut http://doom.wikicities.com/wiki/Editing_tutorial:Making_a_door but make either a line or use your vertices tool and make two dots on the line where you want your switch now click on your newly created line that is tobe your switch and give it a Linedef action in the doors section door generic is a good choice now in the sectors tab put the sector number of your door now if you want to be able to use it multiple times make sure the repetable tag is clicked also make sure that you have the switch action set to "players presses use" now go into 3d mode or another mode in the respective editor and give it a nice switch texture there you go now you have a working switch also with zdoom and other ports you can make other things like crushers,light switches and other things thats all
