Dear all.

I'm completely new to DBp and am trying various noob stuff.

One anomoly I've come up against is a delay when I first try to play a sound.

This is my code...

+ Code Snippet

load image "bat.bmp",1
load image "ball.bmp",2
load sound "boing.wav",1

batx=320
ballx=0
bally=0
ballxx=1
ballyy=1

repeat

    cls rgb(0,0,0)
    sprite 1,batx,450,1
    sprite 2,ballx,bally,2

    inc ballx,ballxx
    inc bally,ballyy
        
    if rightkey() then inc batx,1
    if leftkey() then dec batx,1
    
    if batx<0 then batx=0
    if batx>560 then batx=560   

    if ballx>620 then ballxx=-1
    if ballx<0 then ballxx=1
    if bally>460 then ballyy=-1
    if bally<0 then ballyy=1    

    if sprite hit(1,2)
        ballyy=-1
        play sound 1
    endif

until escapekey()=1

When my ball first hits the bat 'sprite hit (1,2)' there is a delay before it plays the boing.wav sound. After this, it's instantaneous.

Anyone know why? I've done a search, but it didn't come up with anything.

Thank you.

It's because it has to load the sound into memory before playing it.

At the start of your game (right when you initialise everything), load the sound, set the volume to 0, play the sound, and then put the volume back to normal.

The sounds will then all be in RAM and available to play instantly.

Is that the official solution?

It sounds a bit of a bodge to me.

Okay, I've tried the 'if sound playing' method, and have used another type of .wav file. Both still have a pause the first time it's called from the 'sprite hit' condition.

Any other thoughts?

I've attached a RAR'd file of the executable with media, so you should see what I mean. if not, the it must be my PC.
