I'm a little confused about this one. Is it a limit of eleven alarms in my game? or in an object? or an instance of an object?
Thanks a million.
Every Instance of an Object in GML has 12 alarms that can be used (starting from 0 and ending at 11).
PGmath's Sggestion:
If you really need more alarms you can make your own by having a variable which you manually decrement by 1 each step, then test if equal to 0 to perform an action.
