Can't get space when using physics engines direct

[BastiaanOlij]

Godot version:
Godot 3.0.2

OS/device including version:
Windows 10, but not important

Issue description:
The only way to obtain a space object is to use a physics body or area, as I'm using PhysicsServer directly to do testing not supported by the standard physics bodies. It seems a bit overdone to use those as Godot will complain of not adding any collision body nodes but as I'm using shapes directly, don't need those :)

Was talking with @AndreaCatania about adding the ability to get the main space or something like that.

Steps to reproduce:
See example once i have it uploaded

Minimal reproduction project:
This test project shows what I'm trying to accomplish:
https://www.dropbox.com/s/2wvmgddglkkg3oc/Test_teleport.zip?dl=0

In this project have a look at the Function_Teleport.tscn file, you'll see that the root node is a Kinematic Body but there really is no use for it to be a Kinematic Body

Looking at Function_Teleport.gd line 101 - 102, those 2 lines of code obtain the direct state object needed to perform the collision checks I'm doing. To be able to do var space = PhysicsServer.body_get_space(self.get_rid()) I need this node to be a kinematic body.

Can't you use get_viewport().find_world[_2d]().direct_space_state to get the space of the parent viewport?

[AndreaCatania]

Can't you use get_viewport().find_world_2d.direct_space_state to get the space of the parent viewport?

I think that we should create a specific function that does it internally

[BastiaanOlij]

@bojidar-bg I didn't know that, I'll try that tonight!

@AndreaCatania it would be nice as its not a clear step to take

[TGRCdev]

This has been fixed by PhysicsDirectBodyState.get_space_state(), hasn't it?

EDIT: Oct 17, 2019
This is wrong and completely unrelated to the actual issue. My mistake.

@BastiaanOlij Could you confirm the above comment?

[BastiaanOlij]

Owh, I have to find some time this weekend to see if I can verify that claim. If it does that would be splendid.

[TGRCdev]

Doesn't get_viewport().find_world().direct_space_state do what you need?

[AndreaCatania]

Yep, but the idea is to: #17401 (comment)

Closing this issues, since get_viewport().find_world().direct_space_state works.
