[Release]Modify Magic and Rare Items Drop Rate (VSRO188)

MeGaMaX · 05/07/2017, 20:37

Hello,

Since many people keep asking about it, on the other hand @Exo keep asking me for it too, so here is the example function for the RareItems Drop

Note: Most of the silkroad uniques drop factor is hardcoded and limited for example the WhiteSnake can only drop from 1 to 3 elixirs, but Roc can drop between 50-300.

//****VSRO 188 Rare Items Drop Formula ASM Code****//

Spoiler

Note: Rare Items Drop is 1000
SR_GameServer.exe Address:
// Try to drop a rare item with a chance of 1/1000.

Spoiler

/************************************************/

//****VSRO 188 Magic Items Drop Formula ASM Code****//

Spoiler

Note: Magic Items Drop is 30% and this rate is not for the customized items in the database that were already given another values.
SR_GameServer.exe Address:
// If the random value came back over > 30 the whole function will go false.

Spoiler

That's it

,
Greetings MeGaMaX.

So you have the source but you decide to post the ASM version that we all could check.
Uhh, could you please make this release more useful and explain the drops in detail? There's a global drop rate, specific drop groups, ClassSel ref tables. Instead of posting instructions (thanks for releasing them btw, I guess?)
I am not interested in the copy that, paste that stuff. If you can you could perhaps give me a detailed explanation. I'd include it (with credits for sure) at the FayoxDoc when it's published.

I could probably change the exp rate from the src and be happy and never look again to them.

Given the first post about "who cannot handle it" with 90%, you adding yourself up to the 99,9¯%, this is not ... why do I even explain it? Duh.
