superjers ladder has the extra ting that players can't pass trough it but you can shoot and trow grenades trough it nothing else .
also you just need the textures to make the ladder download zhlt.wad from here
and add it in your "hammer - tools - option - textures"
what you need for a simple ladder is 1) a climby part and 2) a solid part
1 : make a thin brush (object rectangle whatever you call it)
apply the AAAtrigger texture on it (from zhtl.wad)
press Ctrl + T and select func_ladder from the list
this is invisible
2: solid / visible part
make another brush, put a ladder texture on it,
put it exactly behind the Climby part ( so they are touching )
make it as thin as your ladder would be in real life
now for superjers ladder (the best one)
1 make the climby part just like before with aaatigger texture
2 make a brush and apply a ladder texture , now press ctrl + T and select "Func_illusionary" this will make it non-solid but visible
3 make one last brush and put the "Clip" texture on it ( also from zhlt.wad ) place this one behind the visible part
any brush that has "clip" texture on it is:
stops players like a normal wall
lest you shoot/ trow grenades trough it like it was air
thats about it ( this is a really long detailed explanation )
