Stepping Sound

[GameDeveloper]

   I was wondering if there was a way to implement stepping sounds?  Maybe it plays the sound of the main characters boot hitting dirt once every (x) amount of pixels?  I recently played a few games by the Author Yogi, and I noticed that he had stepping sounds in his games (It seemed like it, anyway).  Is there a simple way to do this?  Maybe tile interaction?

mmm, one way you could do it is have a function that just raises an event, and is acticated by pressing left or right (not "initial press only" or "all at once" though) and in the media settings have a short walk sound (like one step) play when that function was activated. the sound should not be looping or the interruptalbe/reset one. that should work, haven't tried it

  That sounds like it'll work, but I think there might be one problem.  When the player jumps, and in the air they press toward one of those directions, it will still make the sound, right?  Do you know of a way past this?  Maybe, when up is pressed, remove an item that allows you to activate the sound, and give it back to you when you hit a solid?  If you have any other ideas, it would be greatly appreciated.  I'll go try and implement what you stated in your above post.

yes, that sounds like it should work, but it might be a little messy with hitting walls and everything. you'd have to have all of the "ground" tiles in 2 catagorys, one for solid, and one other one just for adding the inventory. then have a player interaction with that other catagory (not the solid one, the one with only the ground in it) that adds back 1 inventory . 2 problems i can think of are these. 1, what if you walk off a ledge? theres not going to be a way to subtract teh inventory unless you have some sort of invisible non-solid tile a little after the edge that removed the inventory. and 2, what about platform sprites? after you jump wont wont get the inventory back unless you have a collision function set up with the sprite (which will still get a little messy with moving platforms and the whole ledge thing). i'm sure someone else has a better way of doing this (wink wink, durnurd?, bluemonkmn? cbass?), or you could try seeing what the games by yogi did. good luck

If you aren't opposed to using script, the script for this would be relatiely simple: check the tile below the player's feet, and depending on the type of tile it is, play a particular sound effect or don't play any sound effect.  But also check 2 more things before playing the sound effect: check the current frame of the sprite, and check a global variable.  There should be 2 frames on which the sound should play: 1 when the left foot hits the gound and 1 when the right foot hits the ground.  Only play the sound effect if you are on one of these two frames, and if the global variable indicates that you haven't already played it for this frame.  After playing the sound, set the global variable to a new value.

If you're interested in following this thought and need more help, post a reply.

   Maybe I should go with the scripting now.  i would try the other, non-scripting idea billybob884 and me devised, but this might be a faster way. However, I have a question: could it be possible, in the script, to check to see if the player is walking on wood, and play a sound hitting wood, or if he is walking on grass, and play a sound for touching grass, etc.?

Thank you both for your help.

Yes, I tried to suggest that in my post, but I guess I didn't make it clear enough.  When you check what type of tile is below the player, you can choose a different sound effect based on what kind of tile it is.
