failed to fill whole buffer

What causes it and how to fix it? Is it because there is no graphics card?

The source code is: v0.2.0.tar.gz

I think I got a similar error when I didn't had Vulkan installed, maybe that's it? We use bevy and it requires that, we probably need to add bevy requirements to our README

[Zac8668]

Here's bevy requirements: https://github.com/bevyengine/bevy/blob/main/docs/linux_dependencies.md

My guess is that you need to install one of these:

Depending on your graphics card, you may have to install one of the following: vulkan-radeon, vulkan-intel, or mesa-vulkan-drivers

I think I got it all wrong actually, sorry about that, it looks like it messed up the world file, if you delete the world file in assets/world/ it will probably work again, but it will erase you world, sorry about that

[rtczza]

is works!

rm  assets/world/* 
cargo run 

then, you can run the game normally

thanks.

I'm going to leave the issue open because this is a problem with how we deal with the worlds, for now it is not with enough care, without compressing, etc

When we add procedural generation we are going to fix this, but for now it works.
