How to make keyCode == ENTER update a string? - variables

Question

I have my programme here, where you can see I have a string called "S", and a void Get Temperature. At the bottom where keypresses are processed, it has an else If statement with ENTER. I want it so that when you press enter, it updates the string (s) to whatever you have typed, and then load it into the "SetAddress" field. How would I go about this?

AudioPlayer player;
Minim minim;
PImage bg;
String myText;
PFont Bold;
PFont Thin;
TembooSession session = new TembooSession("goldsmiths-c", "myFirstApp", "CNgLbwqnqzGdsnk6wHXPfAnQNSmV0Fmr");
String s = "Enter Location";
int prev = frameCount;
//KeyPressed KeyPressed = new KeyPressed();
void setup() {
size(960, 540);
bg = loadImage("mountains.jpg");
minim = new Minim(this);
player = minim.loadFile("song.mp3");
player.play();
player.loop();

frameRate (30);
}

textFont (Thin);
textSize (48);
text(s, 10, 500);
print(mouseY);
}
void runGetTemperatureChoreo() {
GetTemperature getTemperatureChoreo = new GetTemperature(session);
getTemperatureChoreo.setAddress(s);
getTemperatureChoreo.setUnits("c");
GetTemperatureResultSet getTemperatureResults = getTemperatureChoreo.run();
myText = (s) + (getTemperatureResults.getTemperature() + ("°c"));
print(getTemperatureResults.getTemperature());
}
void keyPressed()
{
if (keyPressed && prev <= frameCount-10) { //If a key is being pressed, and the security/delay is fine with it
prev = frameCount; //re-Init the clock
if (keyCode == BACKSPACE) { //Delete a char!
if (s.length() > 0) {
s = s.substring(0, s.length()-1);
}
} else if (keyCode == DELETE) {
s = "";
} else if (keyCode == ENTER && s.length() != 0) {
} else if (keyCode != SHIFT && keyCode != CONTROL && keyCode != ALT && s.length() < 20) { //It's an ok char, add it to the String
s += key;
}
}
}

Well, it looks like you're storing what the user types in the s variable. You then have this part of your if statement:
else if (keyCode == ENTER && s.length() != 0) {
}
That else if will be entered whenever the user presses enter after typing something. So you just have to put whatever code you want inside the body of that statement:
else if (keyCode == ENTER && s.length() != 0) {
getTemperatureChoreo.setAddress(s);
}
I might not be fully understanding your code, so this is just an example. But the basic idea is the same: to do something when the user presses enter, just put the code you want to happen inside this else if block.
In the future, please try to post an MCVE instead of your entire sketch. For example, your question has nothing to do with minim, so you can get rid of all of that code. Start over with a blank sketch and only add enough code so we can copy and paste it to run it ourselves to see where you're stuck. Good luck.
