Comparing sounds

[Solu9]

Is there a way to compare sounds?
Fx. in a if/then/else loop.

loop
if
Sound_var = sound A
Then
Stop sound immediately
Else

I can't seem to find the condition in the editor.

I doubt one exists for comparing sounds.

Perhaps you should just use a custom script:

• Set Sound1 = Some Sound <gen>
• Set Sound2 = Other Sound <gen>
• Custom script: if udg_Sound1 == udg_Sound2 then
• Sound - Stop Sound1 immediately
• Custom script: else
• Game - Display text to player <..>
• Custom script: endif

It will just check if two sound variables are pointing to the same handle. If you are comparing it with a generated sound variable, then you would have to use gg_snd_, but that is a little more complicated, so it is better to just assign another global and compare the two globals as I did above.

The "else" part is optional. If you don't need it, you can delete the "else" custom script. If/then/elses in JASS behave as: if <some condition> then. Anything after that, and before "else" or "endif" will be evaluated if the condition is true. If it is false, it'll look for an "else" part. If there isn't one, it'll skip to the end of "endif". You don't really need to know this, but that is just some general info for you to work off of.

So, refering do your trigger up there, if Sound1 is a standard sound played. Can Sound2 then act as a buffer sound?

Fx.
If I need to store Sound1 while Sound436 plays.
Can I then set Sound1 = Sound2 so Sound2 act as this buffer?

It is pretty redundant in that example but I hope you get the gist.

I assume by 'buffer' you mean that Sound2 is just a temporary holding place. If so, then yes.

All it is doing is checking if the two sounds are equivalent. Let's say you have some sound variable "Sound_var" and you want to see if it equals the "AltarOfStormsWhat1.wav" variable that you made in the sound editor. Here is one way to check:

• Custom script: if udg_Sound_var == gg_snd_AltarOfStormsWhat1 then

However, it is rather complicated/annoying to type out the sound variable. That is why I made a second variable. It just simplifies the process so you don't have to look up what the JASS equivalent of "AltarOfStormsWhat1" is:

• Set Comparison_Sound = AltarOfStormsWhat1 <gen>
• Custom script: if udg_Sound_var == udg_Comparison_Sound then

But you can really use either one. I just chose the second option since it requires less knowledge of JASS.

Great!
Lovely info.

Thanks Purge.
