I was curious so I did some testing in this c++ reference: https://en.cppreference.com/w/cpp/algorithm/stable_sort and it seems like stable_sort() is faster when there are redundant values, but when they are made quite different on purpose, sort() is faster. -

int CompareLengthSquared(u64 cmpSquared) const { u64 d2 = SQUARE_U64_FIXED(X) + SQUARE_U64_FIXED(Y); // d2 <= 2^63 (no overflow) if (d2 < cmpSquared) return -1; if (d2 > cmpSquared) return +1; return 0; } https://code.wildfiregames.com/source/0ad/browse/ps/trunk/source/maths/FixedVector2D.h#:~:text=int CompareLengthSquared(,} ok so, yes the precision for lengths is 1 meter, but the differences are found for x^2+y^2, so for a 70 meter range archer, 1 meter out of up to 4900 is very little. So basically, the precision when sorting lengths gets higher the farther away the unit is: a single integer represents a range differences of 0.014 meters near 70 meters range. The relationship looks like this: The only thing is the relationship needs to be a parabola, so you can't just do (x^3/Px^2) because this would incorrectly rank units distances. I suppose the thing to do would be to use an integer square root estimation algorithm, and then integer division by the precision value. Then, the profiling would be needed to see if the potential improvements to sorting would be worth it. Even if its pretty similar, I think the impacts on the overkill situation would be nice. https://stackoverflow.com/questions/34187171/fast-integer-square-root-approximation -
Well like anything it depends. Would need to be profiled. @wraitii had an optimization for the range manager here https://code.wildfiregames.com/D5022 not sure what it's worth. -

Weird that it doesn't work in single player. Did you enter it in gamesetup or after the game started? I'll give it a try later. -
real_tabasco_sause, I tried this command on the console. It fails on single player mode, so I had to open 2 instances of 0AD, one as host and one as client. As soon as I entered the command on the host machine I got an OOS. And when I tried this command on the client it failed telling me only hosts can enter this command. So apparently both host and client should be patched via mod before the game starts.
