1.20.1 fabric. adds spikes. many variants:
-iron spikes: when trod on, act like honey, so cannot be jumped on and slow you down, when powered, the spikes retract, and can be walked over, if not powered externally, something tredding on them will make them produce a redstone pulse like a pressure plate.
-bamboo spikes: when trod on, act like honey, so cannot be jumped on and slow you down, when trod on, like void damage, it doubles each time, starting at half a heart, then a heart, then 2, 4, 8, etc, when their damage increases it has a animation where the spikes grow a few pixels. no redstone capabilities, are always dangerous.
-blaze rod spikes, like iron spikes, but they burn you and emit light when trod on.
-end rod spikes, like bamboo spikes with stacking damage, but kills any entity like xp or items dropped onto it.
all spikes but end rod spikes if a hopper is placed beneath will put these items into the hoppers, for a good player trap and entity farming mechanic.
