hud.remove does not work

[Red_King_Cyclops]

I'm adding a HUD feature to a mod. For some reason, I can add a HUD but I cannot remove it. "player.hud_remove(new_hud)" (example) is completely ignored by the program (it does not even give an error message if the ID variable is not declared).

Id is a number tho, correct?

You have to keep the ID given by player.hud_add and pass it to player.hud_remove as argument.

Please, refer to Rubenwardy's modding book, it's full of examples : https://rubenwardy.com/minetest_modding ... s/hud.html

I tried that. I found about hud.remove in Rubenwardy's modding book.

Have you checked that your stored ID is still the good one ?

EDIT: Maybe, post some code

[Eran]

player.hud_remove(handle) won't work since the player has to be passed as argument by using a colon instead of a dot like this player:hud_remove(handle). But that's not the problem here since it would cause an error. Are you sure the relevant code runs? You can verify this using minetest.log. Posting your code here might also help us find the error.

I'm using version 5.0.1. My code looks like this:

Code: Select all

		local fuel_display = clicker:hud_add({
			hud_elem_type = "text",
			position      = {x = 0.5, y = 0.5},
			offset        = {x = 0,   y = 0},
			text          = "Fuel text",
			alignment     = {x = 0, y = 0},
			scale         = {x = 100, y = 100},
		})
                --Later on
		clicker:hud_remove(fuel_display)

Notice that this code is very WIP.

Is the hud_remove in a minetest.after or otherwise delayed? If it's called in the same go as hud_add, removing appearently doesn't work.

The code follows a minetest.after but is not inside one.

[Eran]

Then it's propably not called with a delay. Try putting it inside a minetest.after.
minetest.after basically puts "run that function" on a To-do list for later. The code after the minetest.after call runs right away.

This looks like yet another packet order problem.
1) Lua calls to player:hud_add and sends the packet
2) Lua calls to player:hud_remove in almost the same instant and sends the packet
3) Some time passes: network latency (even on singleplayer)
4) The client receives player:hud_remove and does nothing
5) The client receives player:hud_add and adds the hud

Long story short: Delay your HUD remove function.
