Two slightly different version for what is is worth (not much):
checkKey:=func(k int) int {
if rl.IsKeyDown(k) {
return 1
}
return 0
}
p.Rect.X+=-checkKey(rl.KeyA)+checkKey(rl.KeyD)
p.Rect.Y+=-checkKey(rl.KeyW)+checkKey(,rl.KeyS)
or
checkKey:=func(m,p int) (i int) {
if rl.IsKeyDown(p) {
i++
}
if rl.IsKeyDown(m) {
i--
}
return
}
p.Rect.X+=-checkKey(rl.KeyA,rl.KeyD)
p.Rect.Y+=-checkKey(rl.KeyW,rl.KeyS)
