Hi ! I’m very new to processing and java, and for one of my first programs i need to create data file in .txt to store some variables… but when i use the syntax below, in the .txt file i have this :
-2097152
red
… i can’t figure out why the #e00000 (red colour) turned into “-2097152”…
is my code right ? Thanks for help and sorry for bad english
here is my code :
String preferences;
final int backgroundcolorreference= #000000;
int backgroundcolor;
String clr;
void setup(){
size(800,600);
background(backgroundcolorreference);
}
void draw(){
if (keyPressed==true){
if (keyCode==UP){
backgroundcolor=#ffffff;
clr="white";
}
if (keyCode==DOWN){
backgroundcolor=#e00000;
clr="red;
}
if (keyCode==LEFT){
preferences=backgroundcolor+" "+clr;
String[] tosave = split(preferences," ");
saveStrings("data/saveddata.txt",tosave);
exit();
}
background(backgroundcolor);
}
}
A quotation mark seems to be missing after clr = “red”, but I’m not sure if that’s a copying issue.
Use the hex() function before writing as a string, or else it will get converted to a number (see first example in the reference): https://processing.org/reference/hex_.html
Hey again ! sorry to ask something again but i can’t figure out how to get the color i saved into “saveddata.txt”
String preferences;
final int backgroundcolorreference= #000000;
int backgroundcolor;
String clr;
void setup(){
size(800,600);
background(backgroundcolorreference);
String[] loaded= loadStrings("data/saveddata.txt");
// backgroundcolor= and i dont know what to put here
background(backgroundcolor);
clr = loaded[1];
print(clr," ",backgroundcolor);
}
void draw(){
if (keyPressed==true){
if (keyCode==UP){
backgroundcolor=#ffffff;
clr="white";
}
if (keyCode==DOWN){
backgroundcolor=#e00000;
clr="red";
}
if (keyCode==LEFT){
preferences=hex(backgroundcolor)+" "+clr;
String[] tosave = split(preferences," ");
saveStrings("data/saveddata.txt",tosave);
exit();
}
background(backgroundcolor);
}
}
.
