Help needed with Sound

hendrixnash

Hi all,

I'm currently having some issues with having sound on my piece.

I want it so that whenever I press inside a hotspot, sound plays, and then when the mouse is released from the hotspot, the sound stops.

The issue, however, is that if the very first click is outside of the hotspot, Processing attempts to stop sound that has not yet been loaded and hasn't played yet. If the very first click is inside the hotspot, the sound loads and plays and can stop as I want it to do.

The code is as follows :

If anybody is able to help, I'd appreciate it so much. Thanks in advance

in line 100 insert

if (isMouseDown) {

line 103 }

Chrisir

no need for == true

just if (variable) {

is enough

Sorry for being a pain.. Could you be a little clearer about what I should change? And should this rectify the issue?

Thanks!

Chrisir

??

just check the var and only execute the 2 lines if it's true

Thank you so much!
