I don't think this is readable at all. I think the cascading-ifs
version is much easier to read.
You could do something like the following, but I think pointless
unless there's more to the original snippet:
checkKey:=func(k, v int) int {
if rl.IsKeyDown(k) {
return v
}
return 0
}
p.Rect.X+=checkKey(rl.KeyA,-1)+checkKey(rl.KeyD,1)
p.Rect.Y+=checkKey(rl.KeyW,-1)+checkKey(,rl.KeyS,1)
