timer issues

[LeoStark_84]

Assuming the nodes "xpand:dirt_with_truffle" and "xpand:oak_trunk" are registered.

the following code:


minetest.override_item("default:dirt", {
on_construct = function(pos)
if minetest.find_node_near(pos, 2, "xpand:oak_trunk") ~= nil then
minetest.get_node_timer(pos):start(30)
end
end,
on_timer = function(pos)
local temp = math.random()
if temp > 0.85 then
minetest.set_node(pos, "xpand:dirt_with_truffle")
end
return false
end
})


I thought it would start a 30 seconds timer on every newly placed dirt node, at the end of which there should be a 15% chance that the dirt node will turn into a dirt with truffle node.
The mod starts and I can place dirt nodes correctly. 30 seconds later timers start to trigger.
However when temp is > 0.85 and the line inside the "if" is ran, game crashes with the following message:


2020-08-29 18:12:42: ERROR[Main]: ServerError: AsyncErr: ServerThread::run Lua: Node name is not set or is not a string


There are about 20 "player places node default:dirt" log entries in debug.txt prior to the crash, one (not the first-one) from exactly 30 seconds before.

So, what am I doing wrong?

Thank you for reading so far

set_node expects pos, and a table with the node data.

Code: Select all

 * `node`: table `{name=string, param1=number, param2=number}`

So something like,

Code: Select all

minetest.set_node(pos, {name="xpand:dirt_with_truffle"})

will probably work

Your code worked just perfect. Thank you very much Nathan
