Add a Shape2D node to draw 2D shapes

[I7SOD]

Describe the project you are working on:
Checking out Game engines

Describe the problem or limitation you are having in your project:
I have to create my own Sprite by myself even if I want to use a basic shape like a triangle

Describe the feature / enhancement and how it helps to overcome the problem or limitation:
Add a shape node 2d to handle simple shape objects

Describe how your proposal will work, with code, pseudocode, mockups, and/or diagrams:
A shape2d object that has different basic shapes

If this enhancement will not be used often, can it be worked around with a few lines of script?:
Not sure still a noob

Is there a reason why this should be core and not an add-on in the asset library?:
I don't really know I come from unity background which has it as a core object

I also agree this should be in there. We have something similar for Meshes, but for 2D, there's no easy way (that I know of) to just create a simple shape Sprite.

Are you familiar with the Polygon2D node? https://docs.godotengine.org/en/3.2/classes/class_polygon2d.html

Or do you want to have a set of predefined polygons that you can choose from?

[jonbonazza]

I believe this is for the latter

I am familiar with the polygon node 2d @BeayemX but with the polygon node your shape is offset and gives really bad behavior. I see the polygon node as a way of creating objects like grounds, or objects that don't require precise position. And also the shape is never really accurate. There are lot of problems using the polygon node to create a shape that is used for character movement

I was about to create a proposal related to this then I saw this proposal so I totally agree with this proposal

your shape is offset

That depends on where you are drawing. If your Polygon2D contains the center of your scene, placing instances of your scene should be straight forward and work as expected.

objects that don't require precise position. And also the shape is never really accurate

You can use grid snapping in the 2D viewport to make the points' position precise or adjust the values in the inspector.

There are lot of problems using the polygon node to create a shape that is used for character movement

Like what? The Polygon2D node is just a visualization. This should not have any effect on the character movement.

Overall feedback

These proposals usually work better if we understand what you are trying to do and where the problem occurs. Things like

gives really bad behavior

are hard to relate to if we don't know your use case.

How does this proposal improve the situation?

godotengine/godot#37903 (available since 3.2.2 released yesterday) makes it possible to achieve visuals similar to "Visible Collision Shapes" option via script to draw any Shape2D resources, but there's no way to draw a texture over such shape alone as in Polygon2D, which is much more superior anyways I think, because you can represent any shape with it visually (even if you draw a circle, that's still approximated by series of arcs).

[Xrayez]

So I'm thinking that it should be made possible to add a tool to Convert Shape2D to Polygon2D as well to get the best from both worlds, either directly in the engine or as independent plugin.

I think it will be better as a plugin because for android developers like me I don't really see Godot allowing aab format as of now which makes the code heavier and also the feature isn't really much used at least from how I see it

@AndroidGod101 I actually disagree with you on this one because there is a 3D shape creation node why not have one for 2D, I see that as totally breaking consistency. And as of Godot 3.2.3 there will be support for android aab format (I hope ) because there have been a lot of requests for it check #342 . I don't know much about how frequently it will be used but from my Idea every game uses at least 1 shape

1. For platformers you could use a rectangle shape to create platform and just give it a color or texture resource

2. If you are creating a simple racing game just use circles for the tyre.
   But these are just a few uses on videos I have seen on Youtube where simple shapes are used to create amazing games

@AndroidGod101 Please don't derail the discussion with unrelated proposals. Generally, we want to review proposals individually, not in relation to others.

So do we have a go on this proposal?
