So I'm writing a class that displays a filter over all the images rendered onto my screen. To give my game a more fun effect. So far I have created a flickering effect, which I feel like could be better, it's suppose to feel like a tv that's screen is flickering on and off because its half way broken. My code:
public void initFlicker(){
flick = false;
alpha = 1.0f;
currentTime = getTime();
flickerTime = getTime();
random = new Random();
flickerCount = random.nextInt(10);
waitPeriod = new int[flickerCount];
flickerPeriod = new int[flickerCount];
count = 0;
flickerRest = random.nextInt(5) + 2;
for(int i = 0; i < flickerCount; i++){
waitPeriod[i] = (random.nextInt(10) + 1) * 10;
flickerPeriod[i] = (random.nextInt(10) + 1) * 10;
}
}
public void renderFlicker(){
long time = getTime();
deltaTime = (time - currentTime)/1000;
if(deltaTime >= flickerRest){
if(count < flickerCount){
if(flick){
//flickerPeriod
if((getTime() - flickerTime) < flickerPeriod[count]){
flick();
}else{
flickerTime = getTime();
count++;
flick = false;
}
}else{
if((getTime() - flickerTime) > waitPeriod[count]){
flickerTime = getTime();
flick = true;
}
}
}else{
//Reset Flicker
count = 0;
flickerCount = random.nextInt(10);
waitPeriod = new int[flickerCount];
flickerPeriod = new int[flickerCount];
for(int i = 0; i < flickerCount; i++){
waitPeriod[i] = (random.nextInt(10) + 1) * 10;
flickerPeriod[i] = (random.nextInt(10) + 1) * 10;
}
flickerRest = random.nextInt(5) + 2;
currentTime = getTime();
}
}
}
private void flick(){
GL11.glDisable(GL11.GL_TEXTURE_2D);
GL11.glColor4f(0.0f, 0.0f, 0.0f, alpha);
GL11.glBegin(GL11.GL_QUADS);
GL11.glVertex2i(x, y);
GL11.glVertex2i(x + width, y);
GL11.glVertex2i(x + width, y + height);
GL11.glVertex2i(x, y + height);
GL11.glEnd();
GL11.glEnable(GL11.GL_TEXTURE_2D);
}
Anyone have any tips or ideas on how to improve my code. Thanks.
Also, I'm trying to make a static screen that creates random lines across that move down to the bottom of the screen and only shows a small part of the center of the screen. I attached a png file to show what I would like it to look like.
