Debug renderer: more options for drawing sensors?

[eliasdaler]

Currently, sensors are always drawn in yellow and in wire mode:

It would be nice to have the ability to:

• Draw sensors in solid mode
• Have sensors be colored differently by instance

It would look like this:

Hello,

I think it's a bit much for me to try to cater to everyone's wishes w.r.t. how the debug rendering should look. If you set DrawSettings::mDrawShape = false you can easily render the bodies however you want, e.g.:

BodyIDVector body_ids;
mPhysicsSystem->GetBodies(body_ids);
for (BodyID id : body_ids)
{
	BodyLockRead lock(mPhysicsSystem->GetBodyLockInterface(), id);
	if (lock.Succeeded())
	{
		const Body &body = lock.GetBody();
		if (body.IsSensor())
			body.GetShape()->Draw(DebugRenderer::sInstance, body.GetCenterOfMassTransform(), Vec3::sReplicate(1.0f), Color::sRed /* Pick a color you like */, false, false);
		else
			// Draw the non-sensors in the way you like...
	}
}

Checked out BodyManager::Draw more closely and I see that it doesn't do that much magical stuff or call into any internal APIs after all.

I guess I'll just implement my own, right. :)

Maybe it's worth mentioning somewhere in the docs that your drawing almost from scratch, because so far only this is mentioned:

Finally call for example PhysicsSystem::DrawBodies or PhysicsSystem::DrawConstraints to draw the state of the simulation.

... and this made me think that DrawBodies and DrawConstraints could access some internal state that you couldn't pull yourself. :)
