[CODE][4.2.0] How to determine if a game object is gatherable

[Tanaris4]

The below code snippet allows you to determine if a gameobject is 1) Herb or Mining node and 2) If it's gatherable due to skill level

Huge thanks to JuJu and TOM_RUS, without them I wouldn't have the below. Enjoy!

Assumptions: You have the offsets for Lock.dbc and you understand how to read a row from it. SkillLineOffset is 0x790 and PlayerField_Ptr is 0x11FC (Note: This is for OS X, I'm sure it's close but not the same for windows)

#define NODE_NAMESTRUCT_POINTER_OFFSET     0x1BC

enum eNodeNameStructFields {
	NAMESTRUCT_NAME_PTR         = 0xB4,
	NAMESTRUCT_ENTRY_ID         = 0xC4,
    NAMESTRUCT_LockIndex        = 0x14,            // 0x15C for mining objects!
};

How the f*ck can anyone understand that code? Obj-C must be the most meticulous, confusing language ever...

[Tanaris4]

Your welcome?

[Frosttall]

Try ASM xD

[lanman92]

ASM makes sense. Obj-C is just.... Makes my eyes bleed.

[DarkLinux]

Just because all the script kiddies only understand AutoIt and C# doesn't mean that intelligent people need to dumb down there code for them. I know it does not look perfect, but its your problem you don't understand it, so keep it to your self lols

[Frosttall]

Well, because you've learned ASM... Learn this language and you'll understand it, too xD

Math is confusing, if you don't understand it. But if you understand it, is it easy

Erlang says hi.

Just because all the script kiddies only understand AutoIt and C#...

First time I've heard anyone accusing "script kiddies" of understanding C#


On Topic:

This is awesome. I'm not working on anything that could use this right now but it'll definitely make things easier when I do. Thanks.

Because the language you're coding in shows how intelligent you are? :confused:
And doesn't the term "script-kiddie" reference to people using already-made scripts and programs to achieve something?

Also, as some people seem to think, using a managed language doesn't make you less intelligent. There are tons of advantages from it other than easiness.

[Serpious]

It does, yes. I am not sure if DarkLinux knows what he's talking about.

[Tanaris4]

Bah you would all derail my thread!

Also, the NODE STRUCT thing is 0x1BC, someone asked in IRC (obv could be something else on windows, but usually nearby)

[Tanaris4]

Just discovered this doesn't ALWAYS work (basically it sucks for low level nodes).

The check for lock.Skill[i] > 0 needs to be removed. But, it will try to mine/herb quest items as well, which is obviously a problem.

Anyone have any ideas?

[caytchen]

Blacklisting and whitelisting, of course quest nodes have a LockType, too. You're just causing yourself more trouble.

[Tanaris4]

Yea but there has to be a way. I was going to try "is usable", but I can't find a function for GameObjects... CGGameObject_CanUse actually calls another function, but I don't know which.

[Traxex84]

intelligent people

dumb down there code

Just sayin'
