It seems even if I have a fastloop running in the background doing absolutely nothing, my game still lags when I get to upwards of 300+ iterations. Is there any way to alleviate this?
I should clarify that I'm using I think Nifflas' example on how to use a platform movement object for multiple objects at once, so I have to run a fastloop for each object constantly.
I read somewhere that for each loops are supposed to be faster.
Yeah they are because you can control how many for each loops iterations are created, but I'm making this for XNA in the end and I read ForEach isn't compatible with the XNA exporter.
As far as i heard, the ForEach should be made compatible with XNA ( after release of XNA ).Quote:

Yes. Figure out when you need it to fastloop, and then only fastloop when needed. I can almost guarantee you that you don't need to be running the fastloop at all times.Quote:

That's all good and well Konidias, but I meant even when the fastloop isn't applied to anything and is simply running in the background, it still slows the game down. I need to have the fastloop running constantly because I'm using Nifflas' example for the PMO to be applied to multiple objects.
At any rate, I'm just going to use ForEach and hope by the time I can buy the XNA exporter and release the game, the ForEach will be compatible with XNA. ForEach runs faster because I can force it to apply iterations only to objects on the screen rather than all objects in the entire frame.
Empty fast loops will not effect your framerate.
That's weird, I ran those 10,000 fastloops always and it was fine but when I run an empty fastloop in my current game, it slows it down after 300+ iterations.
Well, unless you feel like uploading your mfa, I guess this is a dead end.
Remember that conditions in events without actions are not checked. If you want to test the speed of only an empty fast loop, you need to put a dummy action in the "on loop" event like running another loop (it doesn't need to exist) 0 times.
Also, make sure to test iterating through a bunch of objects without making an operation (apart from the dummy action) just to see what the slowdowns is.
Loops in MM2 are really inefficient. In most dev platforms it's normal to iterate through tens of thousands of objects, much more than MMF2 can handle even if you optimize everything perfectly. So, it's not always an user error if you can't get something to run fast enough in MMF2, you got to limit your game features according to the dev platform. The ForEach object helps a bit though.
Yeah ForEach is better. It works good in combination with your multiple PMO tutorial. I also optimized the getting rid of PMOs part of it a bit by making the fastloop to remove PMOs only initiate when the number of objects using PMOs changes. I was just hoping there was some trick thing (like built in collision boxes for example) that would speed up fastloops.
Yeah, when I created the PMO thing the ForEach object didn't exist yet. I'm not writing this from a machine with MMF installed, but perhaps it's possible to use ForEach to iterate through PMO objects to detect if its active no longer exist, and iterate through actives to detect if an PMO object has not yet been created for it. That'd get rid of the fastloop need completely.
Doesn't appear as though you can. I just tried to create a ForEach loop for PMO but PMO didn't even show up in the list of objects. Oh well, it's not like running a lot of fastloops for one frame is detrimental to my game.
