[GM7] Speed problems when deactivating instances, Game speeds up when deactivating objects

Well, I'm working at my game Super Mario 2009: The Stars Story. I had to deactivate the solid objects because the game lagged extremely. I did that, and I also needed to deactivate the enemy parent so that they didn't fall through the solids. That means the enemy object (obj_basicenemy) must be deactivated in a smaller region, or else it would fall through the solids if it leaves the bottom of the screen. There isn't a function to deactivate a certain object within a region so I had to use a with statement for that, but now it happens: the game gets super fast, so fast it's just extreme.

This is the deactivation code (end step event):

The room speed is 60, just in case you want to know it. I tried everything but just nothing helps! If you know the solution, then tell it. Thanks.

my guess would be it's the room speed, try 30

instance_deactivate_region(x1,y1,x2,y2,inside,notme)

x1/y1/x2/y2 are the bounds of the rectangle
inside is true/false depending on if it is inside the box or outside of it
notme is whether or not to include the instance performing the code in deactivation

That has nothing to do with it, GM defaulting to 30 is a plague anyways, 60 fps = better looking.

I see no reason why it would go faster, other than the lag cancels out the room speed.
so if 30 helps, then program everything so they move 1/2 the speed they do now.

The strange thing is: in a room without enemies the room goes at normal speed, and when the enemies are in a room it goes crazy. But maybe the room speed is something I'm going to look at.

This might sound crazy, but have you checked to make sure each object's step event is activating only once per frame? Weird things happen when you deactivate/reactivate objects on the same frame.

You mean (de)activating the same object? Or doesn't that matter?

Sorry if I seem newbish.

Not sure. What does matter is the order in which your instances are calling the step event, and you can lose control of that when you deactivate things.

First I'd make absolutely sure whether that's your problem, because it's a fairly obscure glitch. Use show_error to have each instance output its own ID during step. Look for the same ID to appear more than once per frame. If that doesn't happen, then your problem lies elsewhere.

I ran into this issue a year ago and I've forgotten all of the specifics by now, sorry. Here's the post I made at the time. I don't remember exactly how I solved it.

... can you show us the code and their triggers for the enemy objects themselves? If the presence of the enemy object is causing this glitch, shouldn't that be the first place you look?

Well, I fixed it. Now the with statement's gone, everything is OK. Glitch eliminated, problem solved, topic can be closed .
