Rigidbody2D never sleep if they are "characters"

[SuperiorHobo]

Operating system or device - Godot version:
Godot - 2.1 or 2.0/ windows 7

Issue description:
I put some 2d Rigidbodies with "character" mode in scene, they have no any forces applied to them, but debugger show this objects as "active" (with "rigid" mode they sleep and become non active just fine)

Steps to reproduce:
create RigidBody2D with Character mode and zero gravity, watch in monitoring window how it not sleep. Then change mode on Rigid and watch youre have -1 active body

Mhh this seems to be meant as a feature, not a bug :P

//Body2DSW::sleep_test
else if (mode==Physics2DServer::BODY_MODE_CHARACTER)
	return !active; // characters and kinematic bodies don't sleep unless asked to sleep

[SuperiorHobo]

why? if i want to make them sleep by manual i just can switch off "can sleep" func

[kubecz3k]

Yes by design characters should not sleep unless they are explicit asked to, since quite often their logic is processed inside _integrate_forces.

[razcore-rad]

Yeah, this doesn't make any sense to me either. As I understand it, even if _integrate_forces() is implemented the physics server still runs collisions and movement on the object unless custom_integrator is true.

I think sleeping should be managed by the server as long as can_sleep is on and custom_integrator is off as well, but not when custom_integrator is on perhaps.

This definitely needs to be documented better.

This was resolved in 4.0 as part of #48908. The change can't be backported to 3.x to preserve compatibility with existing projects, but this caveat is now documented.
