[Completed] silverhawk feather/agility xp calculator

[Enkilbakstar]

Hey tippers, I was wondering why isn't there a silverhawk feathers agility calculator? I feel it would be incredibly helpful to figure out how many u would need ofc minus bxp to get to a certain lvl. anyway we can find a way to do this?

[Steph]

I believe each feather gives 1/10 of the exp you'd gain from a small lamp

[Enkilbakstar]

well all i know is, as the lvl chances so does ur xp like a lamp, but even a small agility lamp i would get more then 8k xp at me lvl so idk if its 1/10 of the xp, thats why i asked

[Stev]

Find me the rates and you'll have yourself a calculator. ;). I would look into it, but my time over the past week and over the next few days (funeral stuff) has/will be limited.

When recharged the boots have up to 500 charges. Whilst equipped each charge gives Agility experience equal to 10% of the XP rewarded from a small XP lamp. They require a minimum of 1 Defence to wear, and can have their stats changed in increments of 10 up to level 60.

 

So that's what, 860ish at 99. 1720ish with bonus experience

[Stev]

Kks, so it is 10%. I'll work on it - Thanks!

[Stev]

Alright. Just to let ya's know, I put a bit of work into it tonight.

 

I've finished the functions which return feather XP based on level and that calculate feathers needed from level/XP to level/XP. Rewrote my methods for calculating level and XP - which will speed up large future projects. For anyone who's interested, I used to use:

 

 

        function toLevel(n){
            for(i=1;i<=127;i++){
                if(n>=toXP(i)&&n<toXP(i+1))
                    return i;
            }
        }
        function toXP(n){
            var p=0;
            for(l=1;l<=128;l++){
                if(n==l)
                    return l!=127?Math.floor(p/4):200000000;
                p+=Math.floor(l+300*Math.pow(2,l/7));
            }
        }

 

That approach seems to be what's used across most sites. It works well, though for large projects I've rewritten them to:

 

 

Number.prototype.toLevel=function(){
	var valueOf=Math.round(this.valueOf());
	if(valueOf<=0||valueOf>=200000000)
		return valueOf<=0?1:126;
	for(var index=1;index<=127;index++)
		if(valueOf>=index.toXP()&&valueOf<(index+1).toXP())
			return index;
};
Number.prototype.toXP=function(){
	var levelIndex,totalXP=0,valueOf=Math.round(this.valueOf());
	if(valueOf<=1||valueOf>=127)
		return valueOf<=1?0:200000000;
	if(typeof Number.prototype.toXP.arrayOfXP=='undefined'){
		Number.prototype.toXP.arrayOfXP=new Array();
		for(var index=1;index<=125;index++)
			Number.prototype.toXP.arrayOfXP[index+1]=Math.floor((totalXP+=Math.floor(index+300*Math.pow(2,index/7)))/4);
	}
	return Number.prototype.toXP.arrayOfXP[valueOf];
};

 

This way, the first time the method is called it will create/calculate the array of XP. Each call after that, it won't have to loop a potential 126 times (231 times with a single toLevel() call) and calculate each XP - it'll just grab it from the array.

 

Anyways, enough babbling - the calculator will be finished tomorrow. Just wanted to get under the hood finished today. Making it pretty and usable will be tomorrow.

Extend Number to xp dont just add xp methods to the number prototype

[Stev]

Why?

[Hedgehog]

Because toLevel and toXP don't apply to all numbers, just to a specific type of number

[Stev]

I still don't see what's wrong with having it as is - if it's not meant to be called on a specific number then it won't be. But it's much easier to have it as is because of:

variable.toXP();

or

$('#someLevelInput').val().toXP();

or even

(120).toXP();

 

What's the downside to having it as is?

[Hedgehog]

There are benefits to doing it like that, but it isn't "proper" in object-oriented languages

[Stev]

It's standard practice in JavaScript. >.<

 

Edit - In any case, the calculator is finished and public here:

It can be accessed via the special calculators page found here:

I think I got the XP rates very close. The only thing that'd be incorrect is whether or not the XP rates are rounded or floored. Knowing Jagex, I went with floored. In any case, it wouldn't be off by much.

 

Due to it having to do fairly big calculations, slower computers may not like it. For example, to calculate the feathers required for level 1 to 200M XP, it has to loop 243406 times. :P.

 

The inputs support things like 12.3K, 1.2M, etc. ;).

 

 

 

Cheers.

Actually the exp is not rounded. It is 10% to the single digit.

 

For example at 99, it would give 860.2 exp each, however we would see just 860 exp and the occasional 861.

[Stev]

So if something is, say, 306.5, it'd be 30.7?

[Stev]

Thought I'd mention...

 

I updated it to account for Miss Lioness' input.

 

Ambler also recommended that I include bonus experience. The calculator's been updated to reflect this.

 

Also, because large calculations could take up to 3 seconds on slower computers, I stopped it from calculating/planning every time an input lost focus or user pressed enter. To calculate now, click the "Tip Me!" button after filling out all the information.

Sorry for bumping this thread again, but it now shows cost. Feathers exceeding 200M XP will not be counted toward the cost. Cost is based on market value of the Silverhawk Feathers.
