Hello world
I wouldn' say my math skills are horrible, I would rather say I don't have such a skills at all. Whole my life I had deep math phobia, so you can laugh as much as you like, but please tell me:
How to reset from rotate(PI/3.0); in to normal state?
I'm calling function which is rotating an image ( there is a guy and the image is his hand ). It goes like this:
void display() { // display the guy
image(dzih,0,0); // dzih is the name of the guy
hand();
}
void hand() { // set up his hand under certain angle
translate(translateX, translateY); // So far so good
rotate(PI/3.0 + angle); // set up angle // I don't know that yet, but this will cause trouble soon
image(rotateHand, handX, handY); // display hand
if (suprise) { // if start button clicked, move hand
// here is the code for hand animation, doesn't really matter
}
translate(-translateX,-translateY); // reset orgin point
// And here where my problem begin:
HOW To reset from this rotate(PI/3.0 + angle) in to normal state? everyting I draw after is rotated! Must be
silly questions I know, but believe me - I'm not kidding! I have deadline for my coursework tommorow
Also, I want to create array of samples using Sonia library, and later I want to use random() to play sounds from it when,
e.g. mouseClicked(). I think I've set it up properly, but I don't know how to play the samples. Here is what I have:
Global variables:
Sample [] sounds = new Sample[3]; // there will be more in it, but for simplicity just 3
Setup():
String[] filenames = {"sound1.aiff", "another_sound.aiff", "and_another"};
for (int i = 0; i < filenames.lenght; i++) {
sounds[i] = new Sample( filenames[i]);
}
I don't know if it's gonna work, because I dont know how to play them randomly later, If anybody could come with the right commends, it will be strongly appreciated.
Regards
