How to call a function from another Move contract?

Question

Ive deployed a contract with an address 0x3df... and a public function coll. Now, Im trying to write another contract that calls this coll function, but Im getting an error saying use 0x3df...::coll; use is invalid. Unbound module. Ive seen suggestions about using a dependencies file but Im not sure how to implement this properly. What steps should I take to resolve the error and successfully call the function?

To call a function from another Move contract, you need the source code of the first package. If its available locally or on GitHub, you should add it in the Move.toml file as a local dependency. When you published your first package, a Move.lock file was created which contains the packages published address. This address will be used in your other project that depends on this published package. Heres a resource for setting up dependencies: Move Book on Manifest.

Make sure you have set up your local dependencies correctly. Instead of directly using use 0x3df...::coll;, you should ensure that the first package is properly integrated. The error youre seeing generally suggests that the module isnt recognized because its not correctly linked in your dependencies.
