collision sounds at start of scene

forklift

I have a bunch of the same actors stacked on each other that are already touching when the scene starts. I want them to make noise when a collision occurs, but when i have the rule set like so:

when Actor1 touches/collides with Actor1(itself)
play sound

Since they're already touching at the start, i get this erruption of sounds as the actors settle ontop of each other.

How do I work around not playing a sound until after they're settled? It seems that I can't use the rule above to keep these things silent at first until they settle.

Note: I can't see them moving, but for at least 2 seconds they make sounds.

You could put a timer in which says after 3 seconds, then your rules. That way, the rules won't apply for the first 3 seconds of the scene.

I tried that last night, but it didn't work. Maybe I need to set the timer longer. Since that rule didn't work, i figured it was reading collisions after the timer went off.

gazjm

Thats strange, i had a similar problem and that fixed it. Did you have all the rules in eg

timer after 3 run to completion (this needs to be checked from what i can remember)

when Actor1 touches/collides with Actor1(itself)
play sound

forklift

I'll make sure that 'run to completion' is checked after work today, thanks.

forklift

Run to completion doesn't matter. After numerous tests last night, the 'when collision with actor' rule is ALWAYS on no matter what, so I always get the sound at startup. Even when delaying using a timer, it will sound at the start of the scene, then sound again after the timer.

This has to be some kind of bug. I even set up other rules that made it impossible to be 'true' surrounding this sound. It still goes off on the start.

This is stupid.

Anyone know a way around this?

Hi forklift; It's odd it won't work as gazjm said...

Maybe try a boolean attribute, so:

When all conditions are true
when Actor1 touches/collides with Actor1(itself)
when attribute SuchandSuch is true
play sound

with an off-screen actor with a Timer in the Rules,
after 3 seconds
change attribute SuchandSuch to true.

Can't see why that wouldn't work.

forklift

I can't see how it's not working, either. I had the logic set up with a boolean which is ALWAYS off and it still made the sound!! After work, I will try to use an instance to control a game.boolean instead of the actor itself hosting it.

gyroscope

Fingers crossed that works for you. :-)

forklift

This just isn't working. I even started a brand new project and set it up like this:

game has a boolean called game.sound
2 actors: ground & box both have collision rules for eachother
1 instance: timer after 3 seconds set game.sound true
box has a rule: when game.sound = true, play sound on collision with ground & box

as soon as the timer is over, even after all the boxes have settled into place, the sound goes off!

Help!

Im at work at the moment so can't test this to see if its even possible, but I think it is.

Get rid of the timer

set the volume on the sounds to 0, then have a timer which after 3 seconds changes the volume to 1.

this should still let the initial sound play, but you won't be able to hear it as the volume is 0.

Like i said though, im not sure if you can control the volume with a rule, but i think you can.

cheers

forklift

Thanks, that's good thinking, gazjm. I'll see what I can do after the daily grind.

Just wrap the sound behavior in a rule that says when self.time is greater than 2

Don't add a timer when you already have the self.time running anyways.

forklift

More awesome suggestions, thank you so much everyone. I hope to have a video up soon of what I'm doing.

forklift

Scitunes, that method still has the sounds errupting after the self timer goes off.

Tshirtbooth, that method does work, thank you.

tshirtbooth,
I've been trying for four hours (prob longer) to figure it out on my own. No luck. How do you

"at the end of a level i change device.audio.sound to 0
then at the beginning of the level i change device.audio.sound to 1 AFTER 1.5 seconds:"

Is it done through rules in an actor? or some attribute of the scene? Thanks.
