Varbits VarPlayers and Configs

[Teamwork]

I've been wanting to create a questing script recently so I spent some time looking at the Configs class from the api to understand how I can  get access to quest state and such. This led me down a rabbit hole of Varbits and Varplayers and I can't seem to understand how we can access a Varbit from the API. 

If I use configs.get(29) then this should return an int with the state of the quest cook's assistant because 29 is the Varplayer for cook's assistant's current state. But some quests use a Varbit instead of Varplayer, for example if I look at runelite's github or the wiki they both list Varbit 217 as the state of the quest Ghosts Ahoy. So does that mean that using configs.get(217) should return the state of Ghosts Ahoy or it just won't work because the get method only works for Varplayer IDs?(I haven't tested this) If none of the Varplayer and Varbit had the same ID I wouldn't be confused but it turns out Varbit 29 stores the type of rune in the rune pouch and some other IDs overlap as well. 

 

So I guess my question is, how do i access Varbit?

Also I didn't post link to the github or the wiki because I wasn't sure if it was against forum rules. But i can add them if it helps. 

 

Thanks for the help

@Teamwork OSBot doesn't hook var bits. So you can't access var bits with OSBot API. There was talk about adding them a while back, but they decided not to for some reason

Varbits are just a bitmask over the config in the end, so if you get hold of the config, most- and least significant bit, you can get the varbit value via something like this

EQUIPPED_WEAPON_TYPE(843, 5, 0);

private final int configId;
private final int msb;
private final int lsb;

Varbits(int configId, int msb, int lsb) {
    this.configId = configId;
    this.msb = msb;
    this.lsb = lsb;
}

public int getValue(Configs configs) {
    int mask = (1 << ((msb - lsb) + 1)) - 1;
    return (configs.get(configId) >> lsb) & mask;
}

imagine not using the keyword "this" in #getValue.

Wow that's very good stuff thanks for the info, it took me quite a while to understand it all but it makes a whole lot of sense. I didn't know that the Config instance we retrieved with method provider contained both Varplayer and Varbits.

I was looking at this post 

 and the last answer talked about how he got his info from the cache so I'll try to get the lsb, msb and config id from there.
