[1.7.10] How can I tweak the xpBarCap?

[SleepingxForest]

Hey ive been sitting on this for a few days and have acquired a nice collection of crashlogs

 

im trying to make leveling a little harder to do by tweaking the multipliers in the xpBarCap method that returns how much xp you need to level again after doing a little math.

 

i have a bit of game modding under my belt from previous games ive played but im not all that knowledgeable in java however enough to read+understand whats going on for the most part

 

ive been looking into using event handlers to look for the playerpickupxp but im not sure if thats a viable solution and havent been able to figure out how i can use it to override the method in entityplayer that determines what to set the cap at when you level up.

 

i deleted my initial class files out of frustration last night so i dont have my source anymore

 

anyone care to point me in the right direction?

 

it seems like it should be pretty simple right? im probably thinking about it too hard and missing obvious solutions

 

ill probably also be looking to decrease the amount lost on death to make reaching a level harder but a little more sustainable

 

kind of like a MMO style leveling system but with risk still included and makes enchanting more worthwhile

i have alot of other ideas in mind but i havent seen any mods that do something like this so ill share my source code when its finished

I was just messing around and came up with this without using an event handler

got:

oh crap really? well i guess that puts my idea to rest

 

are there any workarounds?

possibly just reducing the xp things drop i guess

 

thank you for the answer

[SleepingxForest]

mind helping me understand how i can call out the entityxporb?

 

i kinda guessed on using the entityjoinworld event

so far i have this. keep in mind its just a guess because im still trying to find what actually determines who drops "x"f of orbs

public class levelupevent extends EntityJoinWorldEvent
{

    public levelupevent(Entity entity) {
	super(entity, world);
	// TODO Auto-generated constructor stub
               // does the auto gen even make a constructor right?
}

public final levelupevent entity;

    public void EntityEvent(levelupevent entity)
    {
        this.entity = entity;
    }
    
}

 

Im not looking to have someone finish the code for me, im looking for the how and why

all help is very appreciated!

You could just make a coremod. ASM is actually pretty fun.

[GotoLink]

@Mod(modid = "exptest", name = "exptest", version = "1.0.0")

public class levelupevent extends EntityPlayer {

In case you haven't learned it yet, that is not how @Mod is used. Look at the basic tutorials on the wiki.

 

As for events, i recommend PlayerPickupXpEvent.
