that is correct you can set idle animations for all 4 directions! all animations work in all 4 directions ( or 8 if the feature is on for the dataset used )
hmmmm so... columns( up and down ), will remain the same, unless your using 8 directional characters. however the rows( left to right ) you can make as many frames for each animation as you want so long as your have the memory for it. :)
that is correct this only applies to characters, the reason being was I am using this as a sort of base for my upcoming ABS( will be live probably pretty soon! ). :)
