Give 300ms delay between coin, kill and power up sounds

Question

I am working on a game that has coins, power ups, and death sounds. The usual for a game. My sound engineer is telling me that in order to make it sound good, I need to have a 300ms delay between all sounds so that they do not play on top of each other and make the sound louder.

E.g., if you pickup multiple coins within that 300ms I don't want to play the sound for all of them.

Here is how I am playing a randomized death sound. But how do I add a delay?

int random = rand() % 4;

switch (random) {
    case 0:
        CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect( enemyDeathSoundName );
        break;
    case 1:
        CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect( enemyDeathSoundName2 );
        break;
    case 2:
        CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect( enemyDeathSoundName3 );
        break;
    case 3:
        CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect( enemyDeathSoundName4 );
        break;

    default:
        break;
}

Does anyone have ideas on how this is possible?

@Patrick I am using `cocos2d-x, so I don't have those `Objective-C` methods available. — Nic Hubbard, Sep 02 '14 at 02:36

use some existing node, and play an delaytime action. like

node->runAction(Sequence.create(DelayTime.create(0.5), CallFunc.create(playSound)));

then play sound in function playSound.

it's a trick, if you don't have a better choice

But would that help if two get cued up at the same time? They would still play on top of each other... – Nic Hubbard Sep 02 '14 at 21:15

You can add in an array the events (as actions) and run the action as a sequence for example you add the event for one enemy in the array and if you killed 3 enemies add multiple actions in an array with the DelayTime and run in a Sequence.

You could check how to add an array (vector) of actions here:
