Unable to compile starter example

[saltlakrits]

Not sure if I'm doing something wrong or not, because I am still very new to Rust, Cargo, Screeps and transpiling, but I can't get anything to compile. I get about 33 errors all (seemingly) relating to the same thing. If required I can paste the whole thing.

Try using the fix-build branch of screeps-game-api. Apparently there's some confusing stuff happening with stdweb atm. To do this, replace the screeps-game-api = "0.6" line in your Cargo.toml with the following : screeps-game-api = { git = "https://github.com/rustyscreeps/screeps-game-api.git", branch = "fix-build" }

Please tell us if it works. We might need to update the starter script.

[ASalvail]

@saltlakrits The branch has been merged, so now you'd need to use master instead of fix-build.

I believe we'll make a release as soon as the factory stuff has been merged.

Apologies for being slow to get back, I had no chance to sit down and try this stuff. After trying to build the starter example again with the master branch of screeps-game-api, I get another couple of errors, but this looks like the starter code is using methods that no longer exist perhaps?

I sadly couldn´t check if my solution is working because somehow my rustc is compiling endlessly. I´m not sure if that issue is related to my changes but that´s what i found.

I ran into the same problem and after a bit of digging in the git history i found the following commit: https://github.com/rustyscreeps/screeps-game-api/commit/aa545b48f8240a493e4abd5e14f219aebbee3841

The api was changed due to deprecation, so the syntax changed from this:

if creep.memory().bool("harvesting") {
    if creep.carry_total() == creep.carry_capacity() {
        creep.memory().set("harvesting", false);
    }
} else {
    if creep.carry_total() == 0 {
        creep.memory().set("harvesting", true);
    }
}

to this:

if creep.memory().bool("harvesting") {
    if creep.store_free_capacity(ResourceType::Energy) == 0 {
        creep.memory().set("harvesting", false);
    }
} else {
    if creep.store_used_capacity(ResourceType::Energy) == 0 {
        creep.memory().set("harvesting", true);
    }
}

You also need to change line 4 to include ResourceType like this:

use screeps::{find, prelude::*, Part, ReturnCode, RoomObjectProperties, ResourceType};

Also you don´t need to use the git version anymore since version 0.7.0 of screeps-game-api released.

Now I got this

With the way we've written the HasStore APIs, store_free_capacity takes an Option<ResourceType>. Specifically, you'll want to use store_free_capacity(Some(ResourceType::Energy)) - or probably, store_free_capacity(None), to account for any non-energy resources.

With #16, the starter code has also been updated to do this.

Compiled without issue! Cool beans, although I think I need a far better grasp on Rust before I can get anywhere, I find the documentation a little hard to follow. Thanks for resolving the issues!
