user
06/03/2016, 6:51 AMSo wrap is the verb? - u
user
06/03/2016, 6:52 AMYeah, I think loop is more about going from 0-9 and then repeating that - u
user
06/03/2016, 6:52 AMAnd it can go backward - u
user
06/03/2016, 2:07 PMIn French we call it something like MODULO - u
user
06/03/2016, 2:07 PMIsn't it that? - u
user
06/03/2016, 2:08 PMModulo gives the remainder from a division - u
user
06/03/2016, 2:08 PMOr .. In english (translated) This number is CONGRUENT to index - u
user
06/03/2016, 2:08 PMYeah ^^ - u
user
06/03/2016, 2:08 PMBut it's something like that - u
user
06/03/2016, 2:08 PMFor example ... 5pi/2 [2pi] (modulo 2 pi) = pi/2 - s

06/03/2016, 7:16 PMow - u
user
06/04/2016, 6:44 PMI have an entity that walks around... And I want it to stop on the edge of the ground - u
user
06/04/2016, 6:44 PMHow can I detect that? - u
user
06/04/2016, 6:44 PMSo it won't fall - u
user
06/04/2016, 6:47 PMDo you want it to stop flush with the edge? - u
user
06/04/2016, 6:50 PMCause you could check the corner points of the entity - u

user
06/04/2016, 6:52 PMIf both points collide, then it's all good - u
user
06/04/2016, 6:53 PMIf one doesn't then it's going off the platform - u
user
06/04/2016, 6:57 PMUh... I mean ..; For something like lemmings .. So they won't fall from the platform - u
user
06/04/2016, 6:58 PMIn Lemmings, don't they just turn around at the edge? - u
