Interactive music script in Cube

slashback79 | 2012-07-05 14:26

I'm doing a project for university looking at audio design for games and I'm using Cube as the game and Audiokinetic's Wwise and the audio engine.
For the most part I can go into the source, modify the code to trigger Wwise sound events for things like weapons and footsteps etc, but I'm struggling getting an interactive music system going.
I have an event in Wwise that contains ambient, tension and action music sequences and there is a game switch to change between them.
What I want to do is have it so ambient is default but if the player is within X distance of a monster the switch is set to tension and if the monster has seen the player the switch is set to action.

I have been following this tutorial which works fine with just one monster but it fails in a single player or deathmatch map with many monsters.
I think its because its checking the distance to the player for every enemy every frame.

Anyone have an idea on how this can be achieved in Cube?

As you seem to know how to code, what about adding tags to the monsters? They already have a trigger right before they die, but not before they wake up (as far as I know, be sure to look into the docs).

An work around could be to set a trigger-entity which could activate a certain sound (this "should" work in cubescript; though I've never managed to get it work) right before the monster activates.

I hope that helped...

Thanks. Actually I'm only a beginner when it comes to c++ so I've mostly been following tutorials.
I'm picking it up pretty quickly though, so I'm going to look into tags.
Thanks for the help

Almost forgot, monsters probably do have a trigger (as for c++, not for cubescript) when they wake up, as they always make their noise to tell they've seen you.
Find that line of code and modify it a little bit could do the job already?

Thanks, I managed to get something working in the end. Basically I used a boolean for whether or not the player is being seen by a monster, and then used monster distance to player and the seen boolean to control which music states play.

So let's share our end result with us?

Sure, well a lot of credit has to be given to the tutorials I followed from this link http://www.gatheral.co.uk/tutorials/wwise/index.php?/archives/3-Music-Transitions.html

Its all done in monster.cpp

First declare a bool for whether the player is seen
bool seen = false;

Then is the monsterstate switch function, allow the seen bool to be true in M_PAIN, ATTACKING, SEARCH and HOME and set seen=false when monster is CS_DEAD and when the map reloads or the player is spawned.

Then use this code, substitute your actions inside the if statements to achieve what you want, in my case switching Wwise music states

if((disttoenemy<=30) && (seen == true) && (critical == false))
{
if (tension == false)

{snd_setmusic(player1, 1571361561);

tension = true;

action = false;

ambient = false;

}
}

if((disttoenemy<=30) && (seen == false) && (critical == false))
{
if (ambient == false)
{snd_setmusic(player1, 77978275);

ambient = true;

tension = false;

action = false;

}
}

If you want to look in more detail I can copy the whole monster.cpp file for you to see.
