I intended to use jbox2d for my project. But as I went deeper into it's manual I'd found out that it supports dynamic objects between 0.1 and 10 meters (if use scaling and assume that 0.1 is smallest unit we would have 100 units). I want to create pretty complex and big shapes about 1000 units width.

• So will box2d will handle it?
• Or I should simplify them more to achieve 100 units width max?
• Or my calculations about 100 units width max are wrong? ( But if 0.1 meter is box2d minimum I don't think than I can get smaller unit as measure.)

I had also read about kollider2d, but can't find any info about stress testing it.

As in comment below:

I understand that it doesn't matter if 32 pixels of my system represents 0.1 meter of box2d system nor if it is 50 pixels. With good scale I can manage any value as minimum. I wan't to create objects 1000 times larger than smallest one. And I don't know if box2d will crash or try to handle it but will be very slow or inaccurate.
