Talk:Tears

Eh, we should probably include stuff from this. https://www.reddit.com/r/bindingofisaac/comments/4rta4f/so_since_the_wikis_page_on_tear_delay_modifiers/ --Chainsawsforhands (talk) 05:02, 7 May 2017 (UTC)

Missing formula for Tear Delay calculation
There is a missing formula in Tear Delay calculation for certain negative values of TotalTears (namely, the case when the expression in the square root isn't negative, but TotalTears itself is still negative, i.e. -0.77 < TotalTears < 0). This is the missing formula: TearDelay = 16 - 6 * sqrt(TotalTears * 1.3 + 1) - TotalTears * 6 (must be rounded down). I checked this formula using the AB+ console and it seems to be correct.

The current formula, 16 - 6 * sqrt(TotalTears * 1.3 + 1), is incorrect for negative values of TotalTears (for example, getting -0.5 tears from Experimental Treatment results in 15 TD in-game while, according to the formula, it's 12 TD; -0.28 from Tears Down pill results in 12 TD in-game and 11 TD according to formula; -0.3 from Death's Touch results in 13 TD in-game and 11 TD as per formula). I tested these negative values with the missing formula and the results matched with in-game values.

I'll add the information to the page, but the formatting and wording could probably be improved. The formula was taken from here: https://docs.google.com/spreadsheets/d/1HsZF-jXtb-zAnJH5Py_b38mv1hv0WZp323efY4ZpMW4/edit?pli=1#gid=596000734

There was an extensive Tear Delay analysis in the reddit thread linked above, but the account associated with that post has been deleted, unfortunately. --Flyingvalenok (talk) 15:39, 7 January 2020 (UTC)
