How to check if resource exists?

Questions
#1

Hi all

I load resources when resource.load, but I dont found info about how to check resource exist.

Help please.

#2

There is no way to check if a filename exists among the custom resources you can embed in a Defold game. But, if you call sys.load_resource() on a resource name that doesn’t exist the function will return nil, and I guess that’s enough right?

You mean some that code

if sys.load_resource(<path_to_resource>) then
local var = resource.load(<path_to_resource>)
end

If yes - that enough thank you

Well, yes. I’m guessing that resource.load() also returns nil if the resource doesn’t exist. Give it a try!

#5

resource.load return script error about resource not found :frowning: And I goto find resolve for problem.

#6

It should be possible to wrap the call to resource.load in a pcall.

Something like this:

local success, result = pcall(resource.load, <path_to_resource>)
if success then
    print("Resource loaded!")
else
    print("Could not load resource, error: " .. tostring(result))
end
