Footsteps Tech Demo (V000-001)

Now dizzy knows how to make sounds of steps while walking.
You can make the sounds different depending on the surface (stone, grass, sand, metal, etc.).
--------------------
A little description of what was done.
--------------------
First the sounds. I took the sounds of footsteps from Counter Strike, they are not really suited to the game, but good to show the idea.
Next, the sounds are thrown into the Samples folder and renamed to our task, it turns out something like this:
10001 pl_step1.wav 10002 pl_step2.wav 10003 pl_step3.wav 10004 pl_step4.wav 10011 pl_wood1.wav 10012 pl_wood2.wav 10013 pl_wood3.wav 10014 pl_wood4.wav 10021 pl_grass1.wav 10022 pl_grass2.wav 10023 pl_grass3.wav 10024 pl_grass4.wav 10031 pl_metal1.wav 10032 pl_metal2.wav 10033 pl_metal3.wav 10034 pl_metal4.wav 10041 pl_sand1.wav 10042 pl_sand2.wav 10043 pl_sand3.wav 10044 pl_sand4.wav 10051 pl_tile1.wav 10052 pl_tile2.wav 10053 pl_tile3.wav 10054 pl_tile4.wav
For each type of surface there are 4 sounds, which will be selected random. Each sound is slightly different from each other, this is done in order to look more natural. First time i tried one sound for all, but i didn't like it.
The sample number is based on the following logic:
The first two digits(counting from left)"10" is to separate step samples from others
The third and fourth digit indicates the material that dizzy is walking
The last digit, the number of the sound in the set for one material.
Further changes in scripts:
sound.gs
#def FX_STEP_0_1 10001 //normal step #def FX_STEP_0_2 10002 #def FX_STEP_0_3 10003 #def FX_STEP_0_4 10004 #def FX_STEP_1_1 10011 //wood floor step #def FX_STEP_1_2 10012 #def FX_STEP_1_3 10013 #def FX_STEP_1_4 10014 #def FX_STEP_2_1 10021 //grass step #def FX_STEP_2_2 10022 #def FX_STEP_2_3 10023 #def FX_STEP_2_4 10024 #def FX_STEP_3_1 10031 //metal step #def FX_STEP_3_2 10032 #def FX_STEP_3_3 10033 #def FX_STEP_3_4 10034 #def FX_STEP_4_1 10041 //sand step #def FX_STEP_4_2 10042 #def FX_STEP_4_3 10043 #def FX_STEP_4_4 10044 #def FX_STEP_5_1 10051 //grass step #def FX_STEP_5_2 10052 #def FX_STEP_5_3 10053 #def FX_STEP_5_4 10054
Sample names are not important, in code used only their numbers.
def.gs #def G_FOOTSTEPS 88 // вкл/выкл звуки шагов #def MAT_STEP 20 // standart step #def MAT_STEP_WOOD 21 // wood floor #def MAT_STEP_GRASS 22 // grass #def MAT_STEP_METAL 23 // metal plates #def MAT_STEP_SAND 24 // sand #def MAT_STEP_STONE 25 // stone The first variable is the flag whether the sounds of steps are ON ot OFF in the game, the rest is the definition of different materials with different surfaces
in handlers.gs in HandlerGameInit function() add material properties:
МaterialSetDensity( MAT_STEP, MATD_HARD ); MaterialSetDensity( MAT_STEP_WOOD, MATD_HARD ); MaterialSetDensity( MAT_STEP_GRASS, MATD_HARD ); MaterialSetDensity( MAT_STEP_METAL, MATD_HARD ); MaterialSetDensity( MAT_STEP_SAND, MATD_HARD ); MaterialSetDensity( MAT_STEP_STONE, MATD_HARD ); MaterialSetColor( MAT_STEP, 0xFF006000 ); MaterialSetColor( MAT_STEP_WOOD, 0xFF006000 ); MaterialSetColor( MAT_STEP_GRASS, 0xFF006000 ); MaterialSetColor( MAT_STEP_METAL, 0xFF006000 ); MaterialSetColor( MAT_STEP_SAND, 0xFF006000 ); MaterialSetColor( MAT_STEP_STONE, 0xFF005000 );
All materials are set to BLOCK property, but you can do other things as needed. For example, the CLOUD property is quite suitable for snow
And in the HandlerGameStart () function, enable the flag of steps depending on the option in the ini file:
// footsteps mode = 1;
// Steps sound is ON by default
gs_inigetint("dizzy.ini", "AUDIO", "footsteps", &mode);
// read parameter from ini-file 'footsteps'
GameSet(G_FOOTSTEPS, mode);
// and writhe it to global variable G_FOOTSTEPS Then in movement.gs in CM_Update function() add the procedure of footsteps sound (I put it in the condition
if(PlayerGet(P_STATUS)!=STATUS_SCRIPTED ))
//steps sound
if(GameGet(G_FOOTSTEPS)) { mat_under=0; for(i=20;i<MAT_MAX-1;i++) { if(IsMaterialUnderPlayer(i)) mat_under = i; }
//here we determine the material on which is now walking Dizzy
if( status == STATUS_WALK && mat_under >= 20)
// check whether the sound of footsteps is ON, is dizzy in the status of the walk and that the material underneath is have sound
{ frame = PlayerGet(P_FRAME);
//check the frame number of the animation
if(frame%8 == 3 || frame%8 == 7 )
//checking if it's a frame where dizzy puts his foot on the ground.
{ dfx = ( mat_under - 20 ) * 10;
//convert the material number to find the sample
ddfx = gs_rand(4)+1;
//select one of four samples for this material by random
fx = 10000+dfx+ddfx;
//the final number of the sample that will sound for (i=SOUND_VOICES-1; i>=0; i--) {
if (SamplePlaying(i) == fx) SampleStop(i); }
//if the selected sample already sounds, then just turn it off, otherwise it will not playing
SamplePlay(fx);//play sample } } }
(here slightly changed that now in the code - cut out debugging information and added comments)
And finally in the map editor assign materials map to those surfaces on which we want hear the steps of those material numbers (20 and more) that we previously defined in def.gs
Now small remarks.
1. The sounds should be as short as possible and not too loud (think 20% or 30% quieter than other sounds), so as not to drown out everything else and not merge into a cacophony.
2. Since the engine produces material under the player in the form of a bitmask, if there are several materials in one place, the sound will be played for the last one in the list
3. Exactly the same principle you can add sounds to dizzy when he is rolling on any surface. Only need the sounds themselves and to experiment on what shots to lose them.
4. All changes were made on a modified engine with a 1-pixel movement Dizzy but the same logic is suitable for a standard engine.
