EFX environment and reverb effect. Closes #697. #702

ArtemPopof · 2019-02-16T11:33:02Z

Some classes to support EFX and realisation of a reverb.
Closes #697

ArtemPopof · 2019-02-16T11:39:39Z

It can be used like this:

// load random sound
size_t index = game->getWorld()->sound.createSfxInstance(555);

auto reverb = std::shared_ptr<SoundEffect>(new ReverbEffect);
auto slot = std::shared_ptr<EffectSlot>(new EffectSlot());
Sound& sound = game->getWorld()->sound.getSoundRef(index);
slot->attachEffect(reverb);
sound.attachToEffectSlot(slot);

game->getWorld()->sound.playSfx(index, {0.0f, 0.0f, 0.0f});

Multiple Sound instances can be attached to one effect slot. Effect slot can be binded to one effect.

default member initializer

ghost · 2019-02-16T22:07:05Z

I've kept possibility to manually operate on basic blocks Sound, SoundSource, SoundBuffer. It's useful to create simple tidy tests. But engine should use neat interface of SoundManager.

It (should) make usage of Sounds simpler and prevent code duplication.

So I think SoundEffect, EffectSlot should be squashed together. Instances of that class stored in vector (which is member of SoundManager).

So code would become something:

// Somewhere in header defined
enum class SoundEffectType {
    None,
    Reverb
};

// load random sound
size_t index = game->getWorld()->sound.createSfxInstance(555);

game->getWorld()->sound.playSfx(index, SoundEffectType::None, {0.0f, 0.0f, 0.0f}); // All logic are done behind

I look forward to your opinion about this idea. ;)

Maybe it's better to remove None from enum and add bool enabled. I think there are too many parameters for sfx to pass them around. Probably we should add some abstraction/wrapper later.

I have problems with understanding connection between this class and SoundEffect. I mean where is EffectSlot created, used, deleted. Because instances of EffectSlot and SoundEffect are in relation 1 to 1. I think solution when one of them contains/owns instances of second would be good enough.
