Preformance Checkup + Audio System
Things I did:
- I stress tested my game to work with 512 & 1024 entities. Ran under 3ms and 5ms. The difference maker was the number of entities currently in the screen (rendering).
- Profiled all the “slow” parts
- Implemented sound system, for menu and game
- Recorded the sounds myself!! (both in-game and ui)!
Performance
I tried my best to find ways to increase speed in my game. Unfortunately, all the things that I thought were “slow” weren’t actually slow.
- Orui UI build was like under 50micro seconds.
- Orui Rendering was under 250micro seconds.
- Animation system ran under 50micro for all entities combined iirc
So, for now, there has been done no performance improvements this devlog
Sound System
First I made the sound system simple, for the menu. It worked and I was happy. I made 6 different similar sounds for the hover and click actions, and I play one of them randomly when clicked.
menu_hover_sounds: [6]rl.Sound
loadMenuSounds :: proc() {
for i in 0 ..< len(menu_hover_sounds) {
path := fmt.ctprintf("res/audio/menu/menu_click_%d.wav", i + 1)
menu_click_sounds[i] = rl.LoadSound(path)
}
}
playMenuHoveredSound :: proc() {
i := rand.int_max(len(menu_hover_sounds))
rl.PlaySound(menu_hover_sounds[i])
}
When I went on to make the Player sounds, I noticed that I am unable to the same sound twice simultaneously. I needed that so that I can simulate multiple enemies and other stuff.
So I googled a bit, found this raylib example. And implemented it. For both menu and entities.
TOTAL_ALIASES :: 4
Sound :: struct {
aliases: [TOTAL_ALIASES]rl.Sound,
index: int,
}
loadSound :: proc(path: cstring) -> Sound {
sound: Sound
sound.aliases[0] = rl.LoadSound(path)
for i in 1 ..< TOTAL_ALIASES {
sound.aliases[i] = rl.LoadSoundAlias(sound.aliases[0])
}
sound.index = 0
return sound
}
playSound :: proc(sound: ^Sound) {
rl.PlaySound(sound.aliases[sound.index])
sound.index = (sound.index + 1) % TOTAL_ALIASES
}
playMenuClickedSound :: proc() {
i := rand.int_max(len(menu_click_sounds))
playSound(&menu_click_sounds[i])
}
I also stole borrowed 
this really great background music from raylib source.
