In a lot of the games, if the sound is behind you, it is muffled. If it is in front of you, it is not muffled. I think the best way of doing it, though, is used in Shades of Doom. There is a drum beat heard if the monsters are behind you.



If you think you're finished, you! really! are! finished!!

Hi.

No need to use any sort of 3D sound, many of the windows games that used
sterrio did not.

what I was thinking in terms of cars or trains is you hear the sounds
passing left to right in front of you, line yourself up according to their
position then take a single hop, after which you move on to the next
obstacle and the previous one is no longer audible, rather the way the
lillypads work now.

Actually, compratively few audio arcade games have used 3D sound, mostly
it's just a combination of sterrio pan and volume which give fairly accurate
ideas, ---- well enough for an arcade game anyway.

All the best,

Dark.

One of the limitations I have is that only stereo is available; I cannot do sounds in front of you versus behind you. By varying the amplitude, I can make a sound seem further away, and it usually sounds in front of you. I licensed the Something Else 3D audio engine for the iphone, but ran into many difficulties and stopped using it.

Many windows games take advantage of 3D sounds, either through having more speakers in the headphones, or by the same algorithms used n the something else 3D engine, but since it was Microsoft that provided the technology, it was far more stable.

Hi Marty.

Obviously previous games of this type haven't had analogue control, but it's a cool idea.

The simplest way would be for the frog to stay static and the cars move from side to side ahead of you and then a tap to hop past each car or set of cars when the coast was clear not using analogue movement at all. That however is missing a key element of gameplay and would probably be limited in challenge.

The second way might be to have a varient of the lilly pads gameplay, with your frog having to cross roads in various directions rather than streight forward, and need to first turn and face the road itself (perhaps with an audio beep when on target), then jump when the sounds of the car or cars were not in the center of the sterrio field.

A more interesting, though probably more problematic idea idea might be that moving your phone left and right moved your frog along the bottom of the road with the cars in front of you, and you could jump at any point.

So for example say you were hearing two cars above you, a fast car coming in from the left and a slower one from the right. Well you might want to jump at the far left to leave the maximum amount of time between the fast moving left cars, provided the right one was out of the way. On the other hand, for two fast moving cars moving at relative speed, the clearest place might be in the center.

I'm not sure how much there would be to add to this in terms of audio mechanics, sinse you'd need to hear the sound of the cars in front of you and being able to move your phone left and right to alter your frog's position relative to the cars, and thus choose whether you wanted to jump in the center, to the right or left depending on the traffic's position.

For example if a very fast car were coming from the left hand side, you might want to get to the far left of the playing area to give yourself maximum time between cars, while if there were two cars moving at relative speeds from opposite ends, then your more likely to have a chance in the center of the field.

Just some thoughts.


Btw, I appologise if this explanation isn't adequate, however if you want some ideas on this type of thing or how to do audio arcade games in general, perhaps checking out previous audio games for pc might help sinse while they don't have analogue control of the Iphone some of the audio sound design for arcade challenges was rather good, the game Hunter for example produced by Bsc programs (and annoyingly now not available sinse the developer went bust and took his games with him), has some very well put together sterrio targeting challenges which add together different elements one after another.

Hopper in particular and the ethos of adding together different elements to make harder levels in audio very much reminded me of Bsc games and Hunter in particular.

All the best,

Dark.
