Blinking text over Video (GSVIDEO)

in Contributed Library Questions • 2 years ago

Hi ho,

can someone explain, how to make a blinking text over a playing video?

This is my try, but the text is flickering:

import codeanticode.gsvideo.*;

GSMovie movie;

int newFrame = 0;

PFont font;

boolean on = true;

void setup() {

size(320, 240);

background(0);

movie = new GSMovie(this, "station.mov");

movie.loop();

font = loadFont("DejaVuSans-24.vlw");

textFont(font, 30);

}

void movieEvent(GSMovie movie) {

movie.read();

}

void draw() {

image(movie, 0, 0, width, height);

if (frameCount % 100 < 50) {

if (on) {

fill(255);

textAlign(CENTER);

text("YOU WIN!", width/2, height/2);

}

on = !on;

}

You were pretty close, see the adapted example below. Use modulo to toggle the blinking every n-th frame (blinkSpeed). In this case every 12th frame the display is toggled ON > OFF > ON > OFF etc. Therefore it will appear to blink.

Code Example

import codeanticode.gsvideo.*;
GSMovie movie;
boolean on;
int blinkSpeed = 12;
void setup() {
size(320, 240);
movie = new GSMovie(this, "station.mov");
movie.loop();
textFont(createFont("Arial",30));
}
void draw() {
image(movie, 0, 0, width, height);
if (frameCount % blinkSpeed == 0) { on = !on; }
if (on) {
fill(255);
textAlign(CENTER);
text("YOU WIN!", width/2, height/2);
}
}
void movieEvent(GSMovie movie) {
movie.read();
}
