Solved Firework spawning (Quick, please!)

Hello, I'm trying to spawn a firework in the onCommand function using:

Code:java

 
Location fireworkLoc = event.getClickedBlock().getRelative(event.getBlockFace()).getLocation();
Firework firework = spawnFirework(fireworkLoc);
FireworkMeta fMeta = firework.getFireworkMeta();
Random rnd = new Random();
 
final List<Color> colour = new ArrayList<Color>();
Collections.addAll(colour, Color.AQUA, Color.BLACK, Color.BLUE, Color.FUCHSIA, Color.GRAY, Color.GREEN, Color.LIME, Color.MAROON, Color.NAVY, Color.OLIVE, Color.ORANGE, Color.PURPLE, Color.RED, Color.SILVER, Color.TEAL, Color.WHITE, Color.YELLOW);
 
List<FireworkEffect> effectList = new ArrayList<FireworkEffect>();
int amount = 1 + rnd.nextInt(3);
 
for(int i = amount; i < 3; i++) {
 
FireworkEffect.Type type = FireworkEffect.Type.values()[rnd.nextInt(5)];
 
List<Color> colorList = new ArrayList<Color>();
int colorAmount = 1 + rnd.nextInt(3);
 
for(int j = colorAmount; j < 3; j++)
colorList.add(colour.get(rnd.nextInt(17)));
 
List<Color> fadeList = new ArrayList<Color>();
int fadeAmount = 1 + rnd.nextInt(3);
 
for(int k = fadeAmount; k < 3; k++)
fadeList.add(colour.get(rnd.nextInt(17)));
//This below is line #73.
FireworkEffect curEffect = FireworkEffect.builder().flicker(rnd.nextBoolean()).trail(rnd.nextBoolean()).with(type).withColor(colorList).withFade(fadeList).build();
 
effectList.add(curEffect);
 
}
 
fMeta.addEffects(effectList);
fMeta.setPower(1 + rnd.nextInt(3));
 
firework.setFireworkMeta(fMeta);
 

It is throwing me this error:

Code:text

I know I shouln't bump so often, but it's year 2013 in 3.5 hours. I'd like to have it done in 30 minutes, so I can use it on my server. Would you mind helping me, please?

Add the colors with a loop. What you're adding is a List and not a single color. I thinks thats the error.

 

I looked at the loop and I noticed that I set it to : 0, 1, 2 colors.
I changed "<" to "<=", it works perfectly! Thanks!

 

wow, that was close...
