But this error come:

Code: Select all

AsyncErr: ServerThread::run Lua: Runtime error from mod 'deathrun' in callback on_respawnplayer(): /home/debiankaios/.minetest/mods/deathrun/auto.lua:8: attempt to call method 'set_pos' (a nil value)

Object won't be an object in that case

Please post the rest of your code - a single line often doesn't show the problem

Code: Select all

minetest.register_on_respawnplayer(function(player, pos)
  if not arena_lib.is_player_in_arena(player:get_player_name(), "deathrun") then return end
  local object = player:get_player_name()
  object:set_pos(checkpoint)
end)

IDK...

Maybe try just using the player itself right away, instead of "object" that is actually player's name and see if it works ? ...

player:set_pos(checkpoint)

No there come the same error

[davidthecreator]

Odd...

Maybe you have to define the checkpoint before using it, if it's not global?

[debiankaios]

Odd...

What?

[davidthecreator]

What?

Are you getting the same error still, or is MineTest crashing over checkpoint now?

The same!

Code: Select all

minetest.register_on_respawnplayer(function(player, pos)
  if not arena_lib.is_player_in_arena(player:get_player_name(), "deathrun") then return end
  local object = player:get_player_name()
  object:set_pos(checkpoint)
end)

The problem is here:

Code: Select all

local object = player:get_player_name()

This line stores the player name into the object variable. Player names are text - strings - and so don't have a set_pos method. Player names are also not ObjectRefs.

You need to call set_pos() on the ObjectRef, not on the player name. You already have an ObjectRef available - player.

Code: Select all

minetest.register_on_respawnplayer(function(player, pos)
  if not arena_lib.is_player_in_arena(player:get_player_name(), "deathrun") then return end
  player:set_pos(checkpoint)
end)

Try using
{x=0,y=0,z=0}
Instead of " checkpoint "...
If you get teleported somewhere, then there is a problem with how checkpoint is defined...

If it still crashes... I have no clue what is wrong anymore...

Thank you, work now!
