Selecting last created Object

[Jaffob]

Pixelthief, I did a test, and it seems that finding an object by fixed value does in fact iterate through all the objects of that type. I tested this by creating a large number of objects with a loop, then using another loop that finds a random object by fixed value each time. Look at the file attached, run the application, then press Space. Note how long a pause you observe in the counter. Then go into the events and increase the number of objects created, and you should see a proportionally longer pause. I changed it from 1000 to 3000 objects, and the pause was about three times longer, so it seems like MMF does iterate through every object to find the one with the right fixed value.

Derp, no file attached. But I take your word on it, so I constructed one of my own. I hadn't thought about judging the time based on increasing the # of objects

If you watch it, for whatever reason, checking by fixed values is faster than by alt. values, but not exponentially as you would expect- it scales up by # of objects like you say. But its always about 3x faster than alt values. So indeed, its not an O(N) way of checking it, its still O(N^2) for sure, but its 3N^2 vs N^2. So yeah, it wouldn't be stable for a critical component of my engine. Which gives me a toughy, do I edit my code so that it might perform marginally faster, when its already 60 FPS and doesn't show any signs of slowdown, or do I make it more stable, when I've scoured my whole engine to make sure theres never any possible bad input anyway? Either one does nothing perceivable off the bat, but a year from now might be a crucial difference. So I'll run with the faster one and comment out but not delete the other
