Failed to load resource: /home/[usr]/.local/share/Rhythm Game Mayhem/Levels/Toby Fox - Spider Dance/audio.wav (-3)

StrategicVirus · September 18, 2025, 11:11am

I am trying to load a .wav file using sys.load_resource, and for a reason i can’t figure out, it is giving me the above error. As i have been typing this out, i do realize that it could just be me trying to load an incompatible file type but if this is the case, it would be helpful if i could get some help as to what would be a better method or an alternative

any help would be greatly appreciated, thanks

sys.load_resource()is for reading resources in our archive file (aka [custom resources](Working with files))

Beware that loading files from any place isn’t a portable way for all the platforms.

As for loading directly from disc, you can use Lua’s io.* module.

Then you can use the [sound.create_sound_data()](API reference (Resource)) to add it to the engine.

Then set the sound [hash property](API reference (Resource)), and you should be ready to play.

Here’s an example, albeit from streaming from Http:

main/sound.script

master


      
          local function http_result(self, _id, response, extra)
          	if response.status == 200 or response.status == 206 or response.status == 304 then
          		--pprint(response.headers)
          		pprint(response)
          		print("Playing web sound:", response.url)
          		local relative_path = self.filename
          		-- local range = response.headers['content-range'] -- content-range = "bytes 0-16383/103277"
          		-- local rstart, rend, filesize = parse_range(range)
          		-- Create the Defold resource, "partial" will enable the streaming mode
          		print("Creating resource", relative_path)
          		local hash = resource.create_sound_data(relative_path, { data = response.response, filesize = response.document_size, partial = true })
          		-- send "play_sound" to the component
          		play_sound(self, hash)
          	end
          end
          
          local function load_web_sound(base_url, relative_path)
          	local url = base_url .. "/" .. relative_path
          
          	local range_start = 0
          	local range_end = 16384-1
