View Full Version : Tradeskill code fix

The current tradeskills code is not working like live code. The code is determining a tradeskill for the container type and as a result allows combines to be done in the wrong containers (ie, pottery has 2 combiners: Pottery Wheel (21) and Kiln (22). These are both used for pottery combines so current code lets either container do all pottery combines.) On live, some recipes require one and some the other.

Also on live, there are recipes that are done in a container that have nothing to do with the tradeskill that the container is normally used for. For example, the Toolbox is normally used by gnomes for Tinkering but can also be used by anybody to recharge tinkered items such as Anizok's Gauze Press. The current code prohibits other characters from doing this combine because of needing the Toolbox. With the new code, the recipes for recharging could be changed to tradeskill 75 and no fail and still use the toolbox.

The new code I am proposing does away with declaring combiners to only do certain tradeskills and eliminates being able to do all tradeskill combines in any container of that tradeskill type. (Example research or cultural recipes).

The following 5 posts show the changes made to the server code to support live like tradeskills. This code is working on my server.

changes made for tradeskills

files changed:
common/item.h
zone/zonedb.h
zone/client.h
zone/client_packet.cpp
zone/tradeskills.cpp

common/item.h

<! SLOT_TRADESKILL = 1000,
!> SLOT_WORLDCONTAINER = 1000,
This change is to make the purpose of the slot more clear. Although the object in the slot can be used for tradeskills, it is a worldcontainer object.

zone/zonedb.h

struct DBTradeskillRecipe_Struct {
!> SkillType tradeskill;
sint16 skill_needed;
uint16 trivial;
bool nofail;
bool replace_container;
vector< pair<uint32,uint8> > onsuccess;
vector< pair<uint32,uint8> > onfail;
};
added SkillType tradeskill; to the structure because the tradeskill should actually be determined by the recipe, not by the type of container you are trying to perform the recipe in.

<! bool GetTradeRecipe(const ItemInst* container, uint8 c_type, uint8 tradeskill, DBTradeskillRecipe_Struct *spec);
!> bool GetTradeRecipe(const ItemInst* container, uint8 c_type, uint32 some_id, DBTradeskillRecipe_Struct *spec);
<! bool GetTradeRecipe(uint32 recipe_id, uint8 c_type, uint8 tradeskill, DBTradeskillRecipe_Struct *spec);
!> bool GetTradeRecipe(uint32 recipe_id, uint8 c_type, uint32 some_id, DBTradeskillRecipe_Struct *spec);
Changed signitures. These should be receiving the item qualifier instead of the tradeskill.

zone/client.h

<! bool TradeskillExecute(DBTradeskillRecipe_Struct *spec, SkillType tradeskill);
!> bool TradeskillExecute(DBTradeskillRecipe_Struct *spec);
Changed signitures. Since SkillType tradeskill is now included in DBTradeskillRecipe_Struct it does not need to be passed separately.

zone/client_packet.cpp

After return from getting recipe (which now identifies tradeskill it wants to use) added code to check classes against tradeskill
changed function call to TradeskillExecute to remove tradeskill from parameter list as it is now included in spec.

KLS is revamping the tradeskills , you need to get in touch - try a PM and link your thread. Tell me if you don't get reply, I'll try and find

While I'm not revamping tradeskills =P I will take a look when I get a chance, thanks.

This looks like a real good fix for tradeskills - I wonder if it ever got into the source?

Yes, it did. Or, at least something did. Tradeskill combines work much better now in that items will only combine in containers that the db tells them to, not any container that is related to it like in the past. Also, there is no longer a need to specify the container type in the code, which means no more broken combines due to the server not knowing what the container is.
