[1.8][SOLVED] How to sort potion effects on HUD

[Jedispencer21]

This is my current code for rendering and laying out the potion effect: http://pastebin.com/bs8gDxX5

You can use Collections.sort, create your own comparator that checks for the duration of the potion

[Jedispencer21]

I sort of thought so and I started to attempt to use it, not quite sure how I would though

there you go

 

EDIT: Maybe show your attempts and tell us ur problem?

Make a comparator, easiest way would be like this:

 

Comparator<PotionEffect> comparator = Ordering.natural().onResultOf(new Function<PotionEffect, Integer>() {
    @Override public Integer apply(PotionEffect potion) {
        return potion.getDuration();
    }
};

 

Or, if you can use Java 8:

Comparator<PotionEffect> comparator = Comparator.comparingInt(PotionEffect::getDuration);

 

Store that in a static field and then sort the Collection before rendering it:

PotionEffect[] effects = effectsCollection.toArray(new PotionEffect[effectsCollection.size()]);
Arrays.sort(effects, comparator)

 

This is 1st time I see " :: " in any piece of java code posted on this forum since I've come here.

Also - very nice post. I was doing it "slower" in past.

Welcome to the magic of java 8 check out lambda expressions

[Jedispencer21]

Now how would I incorporate this with the things like the

PotionEffect potioneffect = (PotionEffect) iterator.next();

Potion potion = Potion.potionTypes[potioneffect.getPotionID()];
