    GMS 2.3+ [Question] Is it possible to mirror/flip a Sequence?

    Hello all, I'm current experimenting with Sequences, and I'm trying to figure out how I can have a Sequence mirrored or flipped during run-time for an Object (similar to a sprite flipped using image_xscale = -1). Doing so, the same movements would occur but in the opposite direction and sprites...

    GML ds_priority_delete_max() returns 0 if the data structure is empty?

    Hellow, I seem to have inadvertently discovered that ds_priority_delete_max() returns 0 if the data structure is empty (and cleared beforehand using ds_priority_clear). Why does the function return 0 at all? Why not "undefined"? Could not find an answer in the documentation.
