How to make Player SFX: Make a sector outside of your map somewhere. It only needs to hold SOUND and TOGGLE SWITCH sprites so it does not need to be big. Inside this sector place a toggle switch sprite and edit it in 2D mode using + keys and change the following data: Type 20 : TOGGLE SWITCH RX ID: 7 TX ID: select a number above 100 (the F10 key will assign one for you) CMD: 1: on tick boxes; x going off x 1- shot Now place a sound sprite in the same outside sector and edit it in 2D mode using the + keys. Change the following data: Type 711: Player SFX RX ID: SAME as the one selected above tick boxes; x going on x 1- shot Data1: the # sound you want to play. (see SFX list) This same basic idea is used for SFX Generators, just place those in the area of your map that you want the sound to be heard and use a TOGGLE SWITCH the same way as above. You can change the RX ID: to anything like one used to work a door or key pick up TX ID: number. then use Data2 to assign the sound number. no other data needs to be edited for these. Monolith uses this alot and if you extract their maps from the game it may be easier to understand after you read this. Good luck, Nailer http://www.greatbasin.net/~griffen/duke.htm
