Hi,

i want to access the stimulusParameter[2] wich is located in the stimuli array to change it from string to color.

"stimuli[j] stimulusParameter[2] = unhex("FF" + stimuli[j] stimulusParameter[2]); "- gives me an error.

How can I do it?

if anybody has an idea i would be very thankful!

stimulus[] stimuli;

void setup() {
size (1024,768);
smooth();
String[] data = loadStrings("data.txt");
stimuli = new stimulus[data.length];

for (int i = 0; i < stimuli.length; i++){

// Each line from the data-Array is split into an array of Strings

String[] stimulusParameter = split(data[i],",");

for(int j = 0; j < stimuli.length; j++){

stimuli[j] stimulusParameter[2] = unhex("FF" + stimuli[j] stimulusParameter[2]);
}

// The stimulusParameters in the Array are passed into the stimulus class constructor.

stimuli[i] = new stimulus(stimulusParameter[0],stimulusParameter[1],stimulusParameter[2]);
}
}
}
void draw(){
background(0);

// stimulus Car = new stimulus ("Car" ,Blue );
// Car.display();

}

// Define Class Stimulus
class stimulus {
char condition;
String word;
color kleur;

// Construct Stimulus
stimulus(String C, String W, color K) {
this.condition = n;
this.word = mouse;
this.kleur = #FF0000;
}

// Method to display Stimulus
void display() {
textAlign(CENTER, CENTER);
textSize(45);
fill(kleur);
text(word, horizPos, vertiPos);
}
}

Hey, i'm absolutely a beginner...

who can tell me how to read out the values from the data.txt (

n,car,#FF0000
c,blue,#0000FF
c,green,#0000FF
i,yellow,#00FF00

)as strings and put each line from the .txt into a seperate array?

Another problem for me will be how to convert the hexcode which is then treated as string to a color.

THX alot to everbody helping me!

(later i want to replace Car and Blue in the line: "stimulus Car = new stimulus ("Car" ,Blue );" with the data from the txt file ...)

stimulus[] stimuli;

void setup() {
size (1024,768);
smooth();
// Load text file as an array of String
String[] data = loadStrings("data.txt");
stimuli = new stimulus[data.length];
//each line from the data is converted into and array
for (int i = 0; i < stimuli.length; i++){
String[] values = String(split(data[i],","));
stimuli[i] = new stimulus(values[0],values[1],values[2]);
}
}

void draw(){
background(0);

stimulus Car = new stimulus ("Car" ,Blue );
Car.display();

}

// Define Class Stimulus
class stimulus {
String condition;
String word;
color kleur;

// Construct Stimulus
stimulus(String C, String W, color K) {
this.condition = n;
this.word = mouse;
this.kleur = #FF0000;
}

// Method to display Stimulus
void display() {
textAlign(CENTER, CENTER);
textSize(45);
fill(kleur);
text(word, horizPos, vertiPos);
}
}
