Linux bin (not Wine) not working?

[tatref]

First off, congratulations for your work!

I tried to run the bot-simple example on a Linux, using the native Starcraft bin (without Wine).

The example seems to start fine, but exists right away. Nothing is ever printed, and exit code is 0. I might be dump, but it seems to me that the into_future function in Melee does nothing if break_on_ctrlc is not true

I tried to fix it by adding a self.run() call (ctrl-C seems to be handled fine): https://github.com/awestlake87/sc2-rs/blob/75a4727cb30c5f1ccb12bfb65b9bc9fbfb4b0729/src/services/melee_service.rs#L207-L209

The program starts fine, until:

Configure: score interface enabled
Configure: render interface disabled
Entering load game phase.
Entering load game phase.

Then nothing else happens. I added a bunch of prints in the bot code, but on_event and on_step are never called.

Using pysc2_agent from https://github.com/deepmind/pysc2 works fine, I get:

Configure: feature layer interface enabled
Configure: score interface enabled
Configure: render interface disabled
Entering load game phase.
Launching next game.
(game is actually running here)

Am I missing something?

The bot-simple example can require some command line arguments to get started properly especially in the headless linux version since there is no standard install location.

What versions and map packs do you have installed and what arguments are you passing into the example program?

Here is how I did the setup:

git clone https://github.com/awestlake87/sc2-rs
cd sc2-rs/

# Download SC2 + maps
wget http://blzdistsc2-a.akamaihd.net/Linux/SC2.4.1.2.60604_2018_05_16.zip
wget http://blzdistsc2-a.akamaihd.net/MapPacks/Ladder2018Season2_Updated.zip
wget http://blzdistsc2-a.akamaihd.net/MapPacks/Melee.zip

# Extract
unzip -P iagreetotheeula SC2.4.1.2.60604_2018_05_16.zip 
unzip -P iagreetotheeula -d StarCraftII/Maps/ Ladder2018Season2_Updated.zip 
unzip -P iagreetotheeula -d StarCraftII/Maps/  Melee.zip

Then I launch bot-simple with:

cargo build --examples

./target/debug/examples/bot-simple -d $PWD/StarCraftII -m $PWD/StarCraftII/Maps/Melee/Simple64.SC2Map

After some more digging, it seems that one of the Starcraft processes is not looking for the correct path. One is uppercase, and the other one is lowercase:

strace -f ./target/debug/examples/bot-simple -d $PWD/StarCraftII -m $PWD/StarCraftII/Maps/Melee/Simple64.SC2Map 2>&1 | grep -i sc2map

(...)
[pid 26808] open("/data/sc2-rs/StarCraftII/Maps/Melee/Simple64.SC2Map", O_RDONLY <unfinished ...>
(...)
[pid 26809] stat("/data/sc2-rs/StarCraftII/maps/Melee/Simple64.SC2Map",  <unfinished ...>

Here, process ID 26809 looks for ../maps/.., whereas process ID 26808 looks for ../Maps/.. (correct path). I'm not sure if this is directly related with sc2-rs.

Strange bug indeed!

Windows (and wine) allows that sort of thing to happen since the paths are case-insensitive. It could be that SC2 is the culprit since linux isn't their primary platform.

They do tell people to use a Maps directory on their page, but my examples have been based on just having a lowercase maps/ in my StarCraftII directory.

I think this problem does originate outside of sc2-rs, but since pysc2 works OK, I think there is probably a way to get around it for the headless linux version. A quick hack to get it working in both cases might be to just symlink Maps to maps in your StarCraftII directory.

[tatref]

You are correct: after renaming the dir to maps/, it works as expected, thanks! I couldn't find any public issue about that for the native Linux exe...

It's still unexpected that one of the processes find the Maps dir, but not the other one.
