I'm trying to put some variety of engine sound. So, I replace the "empty" by the filename of my wav file. But, during in-game, my ships doesn't have this sound. I have modified my ships.tbl to use those news one.
here the code :
$Name: 160 BT_dwn_5.wav, 0, 0.70, 2, 2000, 3000 ; BFGreen warm down
$Name: 161 BT_dwn_6.wav, 0, 0.70, 2, 2000, 3000 ; T_AntiFtr warm down
$Name: 162 Empty, 0, 0.50, 0
$Name: 163 EngineIntAG.wav, 0, 0.90, 1, 200, 400 ; Assault Gunboat engine (3d sound)
$Name: 164 EngineIntAW.wav, 0, 0.90, 1, 200, 400 ; A wing engine (3d sound)
$Name: 165 EngineIntTi.wav, 0, 0.90, 1, 200, 400 ; Tie engine (3d sound)
$Name: 166 EngineIntXW.wav, 0, 0.90, 1, 200, 400 ; X Wing engine (3d sound)
$Name: 167 EngineIntYW.wav, 0, 0.90, 1, 200, 400 ; Y Wing engine (3d sound)
$Name: 168 Empty, 0, 0.50, 0
$Name: 169 Empty, 0, 0.50, 0
Just before the modification I've got this in the table :
$Name: 163 Empty, 0, 0.50, 0
$Name: 164 Empty, 0, 0.50, 0
$Name: 165 Empty, 0, 0.50, 0
$Name: 166 Empty, 0, 0.50, 0
$Name: 167 Empty, 0, 0.50, 0
$Name: 168 Empty, 0, 0.50, 0
