Press x to spawn or swing your mighty axe. Use arrow keys or WASD to move around. Use r and f to zoom in and out
On a Debian machine:
sudo apt install libgl1-mesa-dev xorg-dev
To start the server:
go run ./server
To start the client:
go build ./client
Should I go to /server and go run ., then cd to /client and go run .?
If you try to run client from an incorrect directory, you get a panic (SIGSEGV), because the various images in gamecore/weaponRenderSystem.go cannot be found and are thus initialized to nil.
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x565cab]

Because of this, I propose that we make a type Assets struct{} and a func NewAssets(assetsDir string) (*Assets, error). This way, we can avoid making globals, and ensure that we are handling errors correctly.
I would like to create a PR for this, but I wanted to get your opinions on this.
