anybody encounter this error here and know what's up?
likely a 2.3 issue.
EDIT: oh I see someone below posted a solution to this already my bad:
In GMS v2.3.2, there's been a bugfix where array_length returns undefined instead of 0 when you pass in non-array values.
Replace line 16 in Alarm 0 with effects_al = effects[page] != -1 ? array_length(effects[page])/2 : -infinity;
thx toronto!
EDIT2: Looks like I finally get to view the demo project, but some of the text is showing up 'black' instead of with its appropriate style. unless that's just how that portion is supposed to draw :D
