My next commit on the EQEmu SVN will include an overhauled loot system. It will contain a SQL that will convert your loot tables to the new system preserving both drop rates and drop behavior. I just wanted to post so that everybody understands the new system.
First, the table changes:
Two new columns have been added to loottable_entries called droplimit and mindrop. Probability has been removed from loottable_entries. Multiplier has been added to lootdrop_entries, and chance in lootdrop_entries has been changed to a float so it can handle decimals.
The biggest change is in the new system, each item is rolled individually instead of against every other item in the same lootdrop table. I have already confirmed on PEQ that there is no performance hit with this change. This means that you could potentially have every item on a single lootdrop table per loottable if you so wish. However, multiple lootdrop tables per loottable is still very much supported. The added columns preserve ALL of the functionality the old system, plus adds some new functionality.
The new columns are:
mindrop: This value forces the lootdrop table to always drop the number of items specified. If all of the items are rolled and mindrop is not met, everything is re-rolled until it is. 0 is no mindrop, so the table could potentially drop no items if none are 100%.
droplimit: The opposite of the above column. Once this value is met, no more items will drop from the lootdrop table, even if entries with a 100% chance are left to roll. There is also a chance that the droplimit is not met, and fewer items than the value specified will drop. 0 means there is no limit, and the lootdrop table could potentially drop every item.
multiplier: Same as before really. The simplest way to explain this is it multiplies the other 2 columns. So, if your mindrop is 2 and your multiplier is 4, the lootdrop will drop AT LEAST 8 items. If your droplimit is 2 and your multiplier is 4, the lootdrop will drop NO MORE than 8 items. multiplier is useful if you want a different number range of items to drop every time, instead of just the number of items in the lootdrop table.
It is important to note using either mindrop and multiplier can cause the same item to be dropped multiple times.
It is also important to note that all 3 columns will effect the true percentage every item has of dropping. droplimit may prevent items from even getting a roll at all, mindrop may potentially give items extra rolls, and multiplier will give every item an extra roll per each value (multiplier of 4 gives every item 3 extra rolls.) Setting mindrop to 0, droplimit to 0, and multiplier to 1 will give you 100% clean percentages, meaning the percentage specified in chance will be the exact chance the item has of dropping.
The order the items are rolled is randomly chosen every time, so no items will have an advantage over others due to location in the list.
Last, the new multiplier column in lootdrop_entries works exactly the same way as the one above, except it's per item. So, if you need rats eyes to potentially drop twice, but rat tail to only drop once you can do so and still have them in the same lootdrop table. Any items with multiplier set here receive an extra roll per value, while the ones with it set to 1 do not. Only the first successful roll counts towards mindrop above. So, if mindrop is set to 1 and ration's multiplier is set to 4, you can still drop 4 rations however no other items in that lootdrop will be able to drop.
