ive tried to create one using the keyboardfunctions but still not quite getting it.
int xt = 30;
int max_height = 20;
int min_height = 10;
int letter_height = max_height; // Height of the letters
int letter_width = 10; // Width of the letter
int x = -letter_width; // X position of the letters
int y = 0; // Y position of the letters
boolean newletter;
int numChars = 26; // There are 26 characters in the alphabet
color[] colors = new color[numChars];
PFont fontA;
void setup()
{
size(200, 200);
noStroke();
// Set the font and its size (in units of pixels)
textFont(fontA, 32);
colorMode(RGB, numChars);
background(numChars/2);
// Set a gray value for each key
for(int i=0; i<numChars; i++) {
colors[i] = color(i, i, i);
}
}
void draw()
{
if(newletter == true) {
// Draw the "letter"
int y_pos;
if (letter_height == max_height) {
y_pos = y;
text( x, y_pos, letter_width, letter_height );
} else {
y_pos = y + min_height;
text( x, y_pos, letter_width, letter_height );
fill(numChars/2);
text( x, y_pos-min_height, letter_width, letter_height );
}
newletter = false;
}
}
void keyPressed()
{
// if the key is between 'A'(65) and 'z'(122)
if( key >= 'A' && key <= 'z') {
int keyIndex;
if(key <= 'Z') {
keyIndex = key-'A';
letter_height = max_height;
fill(colors[key-'A']);
} else {
keyIndex = key-'a';
letter_height = min_height;
fill(colors[key-'a']);
}
} else {
fill(0);
letter_height = 10;
}
newletter = true;
// Update the "letter" position
x = ( x + letter_width );
// Wrap horizontally
if (x > width - letter_width) {
x = 0;
y+= max_height;
}
// Wrap vertically
if( y > height - letter_height) {
y = 0; // reset y to 0
}
}
