How does on step work?
I have a node called traps:cage and i want to know when someone walks on it.

The lua_api.txt says: on_step(self,dtime)

My current code is:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: minetest.register_node(":traps:cage",{ tile_images = {"default_grass.png", "default_dirt.png", "default_grass_side.png", "default_grass_side.png", "default_grass_side.png", "default_grass_side.png"}, inventory_image = minetest.inventorycube("default_grass.png", "default_grass_side.png", "default_grass_side.png"), dug_item = '', -- Get nothing groups={immortal}, description = "Mine Trap", on_step=function(pos) print("[Traps:Cage] Activated") minetest.env:add_node(pos,{name="default:dirt"}) local tmp={pos.x-1,pos.y+1,pos.z} minetest.env:add_node(tmp,{name="default:glass"}) end, })

You cant use this in a node definition.

ok, how do you do it?

you can create a list of traps, and add a traps position to that list when you place a trap. use table.insert in the traps node definitions on_construct function.

then you need to check if players are in range of a trap. you can register your own functions to be run periodically.
minetest.register_on_globalstep does that. supply a function that checks if a player is in range of a trap.

hope this helps and there may be better ways to do this...

Take a look at the pressureplates of the mesecon-mod.
