Function to perform pitch bending on a sound in BGT
Hello!
I share with you a function in bgt and that I am using in my game to perform pitch bending on a sound.
It's very simple, follow the code below:
void pitch_bend(sound@ soundfile, double value, string mode, int time){
double original_value=soundfile.pitch;
while (soundfile.playing and value>1 or value>200){
if(mode=="up") value=value+1;
else if (mode=="down") value=value-1;
soundfile.pitch=value;
wait(time);
}
soundfile.pause();
soundfile.pitch=original_value;
soundfile.stop();
}
To test, you can do something like this:
#include "pitchbend.bgt"
sound test;
void main(){
show_game_window ("Pitch bend");
test.load ("filename.wav");
test.play();
wait (5000);
pitch_bend(@test,80,"down",25);
}
Or else:
#include "pitchbend.bgt"
sound test;
void main(){
show_game_window ("Pitch bend");
test.load ("filename.wav");
test.play();
wait (5000);
pitch_bend(@test,test.pitch,"up",50);
}
I hope this is useful.
